Children aren't just small adults. It is especially important to remember this when giving medicines to children. Giving a child the wrong dose or a medicine that is not for children can have serious side effects.

The drug labels for prescription medicines have a section on "Pediatric Use." It says whether the medicine has been studied for its effects on children. It also tells you which age groups were studied. Some over-the-counter (OTC) medicines, like those that treat fever and pain, have been studied for effectiveness, safety, or dosing in children. But many other OTC medicines have not. It is important to read the labels carefully, to make sure that the medicine is right for your child.

Here are some other tips for giving medicine safely to your child:

• Read and follow the label directions every time. Pay special attention to usage directions and warnings.
• Watch out for problems. Contact your health care provider or pharmacist right away if
• You notice any new symptoms or unexpected side effects in your child
• The medicine doesn't appear to be working when you expect it to. For example, antibiotics may take a few days to start working, but a pain reliever usually starts working soon after your child takes it.
• Know the abbreviations for the amounts of medicines:
• Tablespoon (tbsp.)
• Teaspoon (tsp.)
• Milligram (mg.)
• Milliliter (mL.)
• Ounce (oz.)
• Use the correct dosing device. If the label says two teaspoons and you're using a dosing cup with ounces only, don't try to guess how many teaspoons it would be. Get the proper measuring device. Don't substitute another item, such as a kitchen spoon.
• Check with your health care provider or pharmacist before giving two medicines at the same time. That way, you can avoid a possible overdose or an unwanted interaction.
• Follow age and weight limit recommendations. If the label says don't give to children under a certain age or weight, then don't do it.
• Always use the child-resistant cap and re-lock the cap after each use. Also, keep all medicines out of the reach of children.
• Ask your health care provider or pharmacist if you have any questions.

Antibiotics are medicines that fight bacterial infections. Used properly, they can save lives. But there is a growing problem of antibiotic resistance. It happens when bacteria change and resist the effects of an antibiotic. Resistant bacteria may continue to grow and multiply.

Each time you take antibiotics there is a risk that the bacteria will become resistant. Resistant infections can be difficult and sometimes impossible to treat. They can spread to other people. Methicillin-resistant Staphylococcus aureus (MRSA) is one example. It causes infections that are resistant to several common antibiotics.

Antibiotic resistance can cause problems. To help prevent antibiotic resistance:

• Don't use antibiotics for viruses like colds or flu. Antibiotics don't work on viruses.
• Don't ask your health care provider to give you an antibiotic.
• When you take antibiotics, follow the directions carefully. Finish your medicine even if you feel better. If you stop treatment too soon, some bacteria may survive and re-infect you.
• Do not share your antibiotics with others.
• Don't save antibiotics for later or use someone else's prescription.

Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.

Antibiotics can be taken in different ways:

• Orally (by mouth). This could be pills, capsules, or liquids.
• Topically. This might be a cream, spray, or ointment that you put on your skin. It could also be eye ointment, eye drops, or ear drops.
• Through an injection or intravenously (IV). This is usually for more serious infections.

Antibiotics only treat certain bacterial infections, such as strep throat, urinary tract infections, and E. coli.

You may not need to take antibiotics for some bacterial infections. For example, you might not need them for many sinus infections or some ear infections. Taking antibiotics when they're not needed won't help you, and they can have side effects. Your health care provider can decide the best treatment for you when you're sick. Don't ask your provider to prescribe an antibiotic for you.

Antibiotics do not work on viral infections. For example, you shouldn't take antibiotics for:

• Colds and runny noses, even if the mucus is thick, yellow, or green
• Most sore throats (except strep throat)
• Flu
• Most cases of bronchitis

The side effects of antibiotics range from minor to very severe. Some of the common side effects include:

• Rash
• Nausea
• Diarrhea
• Yeast infections

More serious side effects can include:

• C. diff infections, which cause diarrhea that can lead to severe colon damage and sometimes even death
• Severe and life-threatening allergic reactions
• Antibiotic resistance infections

Call your health care provider if you develop any side effects while taking your antibiotic.

You should only take antibiotics when they are needed because they can cause side effects and can contribute to antibiotic resistance. Antibiotic resistance happens when the bacteria change and become able to resist the effects of an antibiotic. This means that the bacteria continue to grow.

When you take antibiotics, it is important that you take them responsibly:

• Always follow the directions carefully. Finish your medicine even if you feel better. If you stop taking them too soon, some bacteria may survive and re-infect you.
• Don't save your antibiotics for later.
• Don't share your antibiotic with others.
• Don't take antibiotics prescribed for someone else. This may delay the best treatment for you, make you even sicker, or cause side effects.

Antidepressants are prescription medicines to treat depression. Depression is more than feeling a little sad or "blue" for a few days. It's a very common, serious medical illness that affects your mood and general mental health It can make you feel tired, hopeless, worried, or fearful. It can change your thinking, sleeping, and eating. Depression may make some people think about ending their lives.

But antidepressants can help many people who have depression. Researchers think antidepressants may help improve the way your brain uses certain chemicals that control mood or stress.

A health care provider may prescribe antidepressants for anxiety, chronic pain, or insomnia. Sometimes providers also prescribe antidepressants for other conditions.

There are many types of antidepressants. Each one works differently. Providers usually prescribe newer antidepressants first because they don't cause as many side effects as older types. They also seem to help more kinds of depression and anxiety problems.

Most of the newer antidepressants belong to one of these three groups:

• Selective serotonin reuptake inhibitors (SSRIs)
• Serotonin and norepinephrine reuptake inhibitors (SNRIs)
• Atypical antidepressants, which are newer antidepressants that don't fit into the other groups

If these antidepressants don't help, your provider might suggest one of the older antidepressants. The older types include tricyclic antidepressants (TCAs), tetracyclics, and monoamine oxidase inhibitors (MAOIs). Even though these antidepressants may cause more serious side effects, the benefits may outweigh the risks for some people.

Our bodies and brains all work differently. That means one antidepressant won't work for everyone. You may need to try two or more medicines before you find one that works for you.

Your provider will work with you to choose the best option to try first. You'll consider questions such as:

• Which symptoms bother you most? Some antidepressants may do a better job helping specific symptoms, such as trouble sleeping.
• What other medicines and supplements do you take? Some antidepressants can cause problems if you take them with certain medicines and herbs.
• Did a certain antidepressant work well for a close relative? An antidepressant that helped a parent, brother, or sister could be a good choice for you, too.
• Do you have other health conditions? Certain antidepressants can make some other conditions better or worse. Any other conditions that you have will be part of choosing your depression treatment.
• Are you pregnant, planning for pregnancy, or breastfeeding? If so, your provider will help you find a way to treat your depression that's safe for you and your baby.

Antidepressants usually take 4 to 8 weeks to work, so you'll need to be patient. You may notice that some problems, such as sleeping and eating, get better before your mood improves. That's a good sign. You may just need to give the medicine a little more time to do its job.

Sometimes an antidepressant helps at first, but symptoms return while you're still taking it. But there's usually another one you can try. To get more relief from depression, your provider may suggest combining two antidepressants, using another kind of medicine with an antidepressant, or adding talk therapy or other approaches to improve your mental health.

When an antidepressant starts to work, you and your provider can decide how long you need to stay on it. The typical length of treatment is 6 to 12 months, but some people may stay on antidepressants for much longer.

Not everyone has side effects from antidepressants. But if you do have them, they're usually mild and may get better over time as your body gets used to the new medicine.

The most common side effects from antidepressants include:

• Nausea and vomiting
• Weight gain
• Diarrhea
• Sleepiness
• Sexual problems, such as a lack of desire or ability to have sex

When thinking about side effects, it's important to remember that there are also risks from not treating depression. Your provider can help you think through the pros and cons of all your options.

If you have any side effects from antidepressants, your provider may suggest ways to manage them while you wait to see if the antidepressant will work. If the side effects bother you too much, you may need to change antidepressants. But you should never change your dose or stop taking an antidepressant on your own.

If you have serious problems or notice any changes that worry you, such as new or worsening symptoms, unusual changes in your mood, or you start acting differently, call your provider right away.

In some cases, children, teenagers, and young adults under 25 may be more likely to think about hurting or killing themselves when starting antidepressants or when the dose is changed. Get medical help right away if this happens.

Antidepressants are generally safe when you use them correctly:

• Tell your provider about everything you take. That includes medicines, herbs, supplements, and over-the-counter medicines you take, such as pain relievers and decongestants. Be honest about recreational drugs and alcohol, too.
• Try to get all your medicines from the same pharmacy. That way the pharmacist can warn you and your provider if you take medicines that may cause problems when used together.
• Follow all instructions about how to take your medicine.
• Talk with your provider if side effects bother you.
• Never stop taking antidepressants without your provider's help. Stopping too fast may make depression come back. You could even make your condition worse. To stop antidepressants safely, you need to give your body time to get used to being without the medicine. Your provider can tell you the safest way to go off an antidepressant.

High blood pressure, also called hypertension, is when blood puts too much pressure against the walls of your arteries. Almost half of American adults have high blood pressure, usually with no symptoms. But it can cause serious problems such as stroke, heart failure, heart attack, and kidney disease.

Healthy lifestyle changes can help reduce high blood pressure:

• Losing weight
• Being physically active
• Managing stress
• Reducing sodium in your diet
• Avoiding alcohol, tobacco, and illegal drugs
• Getting enough sleep

Sometimes lifestyle changes alone cannot control or lower your high blood pressure. In that case, your health care provider may prescribe blood pressure medicines.

The most commonly used blood pressure medicines work in different ways to lower blood pressure:

• Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) keep your blood vessels from narrowing as much and allows blood to move through them with less pressure.
• Beta blockers help your heart beat slower and with less force. This means that your heart pumps less blood through your blood vessels. Beta blockers are typically used only as a backup option or if you also have certain other conditions.
• Calcium channel blockers prevent calcium from entering the muscle cells of your heart and blood vessels. This allows the blood vessels to relax.
• Diuretics remove extra water and sodium (salt) from your body. This lowers the amount of fluid in your blood. Diuretics are often used with other high blood pressure medicines, sometimes in one combined pill.

Often, two or more medicines work better than one. If these medicines do not lower your blood pressure enough, your provider may suggest that you take another type of blood pressure medicine.

While taking the medicines, it is still important to keep up with your healthy lifestyle changes. Doing both helps keep blood pressure lower than lifestyle changes or medicines alone.

Blood thinners are medicines that prevent blood clots from forming. They do not break up clots that you already have. But they can stop those clots from getting bigger. It's important to treat blood clots, because clots in your blood vessels and heart can cause heart attacks, strokes, and blockages.

You may need a blood thinner if you have:

• Certain heart or blood vessel diseases
• An abnormal heart rhythm called atrial fibrillation
• A heart valve replacement
• A risk of blood clots after surgery
• Congenital heart defects

There are different types of blood thinners:

• Anticoagulants, such as heparin or warfarin (also called Coumadin), slow down your body's process of making clots.
• Antiplatelets, such as aspirin and clopidogrel, prevent blood cells called platelets from clumping together to form a clot. Antiplatelets are mainly taken by people who have had a heart attack or stroke.

When you take a blood thinner, follow the directions carefully. Blood thinners may interact with certain foods, medicines, vitamins, and alcohol. Make sure that your health care provider knows all of the medicines and supplements you are using.

You may need regular blood tests to check how well your blood is clotting. It is important to make sure that you're taking enough medicine to prevent clots, but not so much that it causes bleeding.

Bleeding is the most common side effect of blood thinners. They can also cause an upset stomach, nausea, and diarrhea.

Other possible side effects can depend on which type of blood thinner that you are taking.

Call your provider if you have any sign of serious bleeding, such as:

• Menstrual bleeding that is much heavier than normal
• Red or brown urine
• Bowel movements that are red or black
• Bleeding from the gums or nose that does not stop quickly
• Vomit that is brown or bright red
• Coughing up something red
• Severe pain, such as a headache or stomachache
• Unusual bruising
• A cut that does not stop bleeding
• A serious fall or bump on the head
• Dizziness or weakness

Cancer chemotherapy is a type of cancer treatment. It uses medicines to destroy cancer cells.

Normally, the cells in your body grow and die in a controlled way. Cancer cells keep growing without control. Chemotherapy works by killing the cancer cells, stopping them from spreading, or slowing their growth.

Chemotherapy is used to:

• Treat cancer by curing the cancer, lessening the chance it will return, or stopping or slowing its growth.
• Ease cancer symptoms by shrinking tumors that are causing pain and other problems.

Chemotherapy does not just destroy cancer cells. It can also harm some healthy cells, which causes side effects.

You may have a lot of side effects, some side effects, or none at all. It depends on the type and amount of chemotherapy you get and how your body reacts.

Some common side effects are:

• Mouth sores
• Fatigue
• Nausea and vomiting
• Pain
• Hair loss

There are ways to prevent or control some side effects. Talk with your health care provider about how to manage them. Healthy cells usually recover after chemotherapy is over, so most side effects gradually go away.

You may get chemotherapy in a hospital or at home, a doctor's office, or a medical clinic. You might be given the medicines by mouth, in a shot, as a cream, through a catheter, or intravenously (by IV).

Your treatment plan will depend on the type of cancer you have, which chemotherapy medicines are used, the treatment goals, and how your body responds to the medicines.

Chemotherapy may be given alone or with other treatments. You may get treatment every day, every week, or every month. You may have breaks between treatments so that your body has a chance to build new healthy cells.

Cold and cough medicines can help relieve symptoms of a common cold. The symptoms of a cold can include a sore throat, stuffy or runny nose, sneezing, and coughing.

You don't usually need to treat a cold or the cough that it causes. You can't cure a cold, and antibiotics won't help you get better. But sometimes the symptoms can keep you awake or cause a lot of discomfort. In that case, cold and cough medicines can sometimes be helpful.

There are lots of different cold and cough medicines, and they do different things:

• Nasal decongestants - unclog a stuffy nose
• Cough suppressants - quiet a cough
• Expectorants - loosen mucus in your lungs so you can cough it up
• Antihistamines - stop runny noses and sneezing
• Pain relievers - ease fever, headaches, and minor aches and pains

Before taking these medicines, read the labels and follow the instructions carefully. Many cold and cough medicines contain the same active ingredients. For example, some of them include pain relievers. If you are taking these medicines and are also taking a separate pain reliever, you could be getting a dangerous amount of the pain reliever.

Do not give cold or cough medicines to children under two, and don't give aspirin to children.

If you decide that you don't want to take cold and cough medicines, there are other ways to feel better:

• Drink lots of fluids
• Get plenty of rest
• Use a cool mist humidifier
• Use saline nose drops or sprays
• Use nasal suctioning with a bulb syringe, which can be very helpful in children under a year old

Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. The cells of your body need glucose for energy. A hormone called insulin helps the glucose get into your cells.

Treatments for diabetes can depend on the type. Common treatments include a diabetic meal plan, regular physical activity, and medicines. Some less common treatments are weight loss surgery for either type and an artificial pancreas or pancreatic islet transplantation for some people with type 1 diabetes.

People with type 1 diabetes need to take a diabetes medicine called insulin to control their blood sugar.

Some people with type 2 diabetes can control their blood sugar with healthy food choices and physical activity. But for others, a diabetic meal plan and physical activity are not enough. They need to take diabetes medicines.

The kind of medicine you take depends on your type of diabetes, daily schedule, medicine costs, and any other health conditions that you have. Over time, you may need to take more than one diabetes medicine.

If you have type 1 diabetes, you must take insulin because your body no longer makes it. There are different types of insulin that start to work at different speeds, and the effects of each last a different length of time. Your health care provider will measure your blood glucose to decide on the type of insulin. You may need to use more than one type.

You will also need to check your blood sugar at home. Your provider will tell you how often. The results of your blood sugar testing can help you make decisions about food, physical activity, and medicines.

You can take insulin several different ways. The most common are with a needle and syringe, an insulin pen, or an insulin pump. If you use a needle and syringe or a pen, you have to take insulin several times during the day, including with meals. An insulin pump gives you small, steady doses throughout the day. Less common ways to take insulin include inhalers, injection ports, and jet injectors.

In rare cases, taking insulin alone might not be enough to manage your blood sugar. Then you would need to take another diabetes medicine.

There are several different medicines for type 2 diabetes. Each works in a different way. Many of them are pills. There are also medicines that you inject under your skin, such as insulin.

Over time, you may need more than one diabetes medicine to manage your blood sugar. You might add another diabetes medicine or switch to a combination medicine. A combination medicine contains more than one type of diabetes medicine in the same pill. Some people with type 2 diabetes take both pills and injections.

Even if you don't usually take insulin, you may need it at special times, such as during pregnancy or if you are in the hospital.

Even if you take medicines for diabetes, you still need to eat a healthy diet, stop smoking, take your other medicines, and get regular physical activity. These will help you manage your diabetes.

It is important to make sure that you understand your diabetes treatment plan. Talk to your provider about:

• What your target blood sugar level is
• What to do if your blood sugar gets too low or too high
• Whether your diabetes medicines will affect other medicines you take
• If you will have any side effects from the diabetes medicines

You should not change or stop your diabetes medicines on your own. Talk to your provider first.

Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions, such as drug interactions, side effects, and allergies.

A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs, foods, or supplements or when taken while you have certain medical conditions. Examples include:

• Two drugs, such as aspirin and blood thinners
• Drugs and food, such as statins and grapefruit
• Drugs and supplements, such as gingko and blood thinners
• Drugs and medical conditions, such as aspirin and peptic ulcers

Interactions could cause a drug to be more or less effective, cause side effects, or change the way one or both drugs work.

Side effects are unwanted, usually unpleasant, effects caused by medicines. Most are mild, such as a stomachache, dry mouth, or drowsiness, and go away after you stop taking the medicine. Others can be more serious. Sometimes a drug can interact with a disease that you have and cause a side effect. For example, if you have a heart condition, certain decongestants can cause you to have a rapid heartbeat.

Drug allergies are another type of reaction. They can range from mild to life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is less common.

When you start a new prescription or over-the-counter medicine, make sure you understand how to take it correctly. Know which other medicines, foods, and supplements you need to avoid. Always talk to your health care provider or pharmacist if you have questions about your medicines.
