Medicines and Children

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:

Antibiotic Resistance

What are antibiotics?

Antibiotics are medicines that treat bacterial infections in humans and animals. They work by killing the bacteria or making it hard for the bacteria to grow and multiply. When used properly, antibiotics can save lives. But there is a growing problem of antibiotic resistance.

What is antibiotic resistance?

Antibiotic resistance happens when bacteria change and can resist the effects of an antibiotic. The bacteria are not killed, and they continue to grow. The infections these bacteria cause are called resistant infections. Resistant infections can be difficult, and sometimes impossible, to treat. In some cases, they can even be deadly.

Antibiotic resistance does not mean that your body is resistant to antibiotics.

There are many different types of resistant infections. They include MRSA and drug-resistant tuberculosis (TB). If you get a resistant infection, you might need:

Antibiotic resistance is one type of antimicrobial resistance. There are other types; viruses, fungi, and parasites can also become resistant to medicines.

How do bacteria become resistant to antibiotics?

Antibiotic resistance is a natural process that happens over time. To survive, bacteria can develop defense strategies against antibiotics. This happens through genetic changes in the bacteria. These resistant bacteria survive, grow, and spread.

Each time you take antibiotics, there is a risk that the bacteria will become resistant. So it is important to only take antibiotics when you really need them. They won't work on viral infections such as colds and the flu. And you don't need antibiotics for every bacterial infection. For example, you may not need them for some sinus and ear infections.

Who is more likely to develop an antibiotic-resistant infection?

Anyone can develop an antibiotic-resistant infection, but certain people may be at higher risk, including those who:

How can antibiotic resistance be prevented?

There will always be some antibiotic resistance, since it happens naturally. But you can help fight against antibiotic resistance by taking these steps:

Antibiotics can be taken in different ways:

What do antibiotics treat?

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.

Do antibiotics treat viral infections?

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

What are the side effects of antibiotics?

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

More serious side effects can include:

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

Why is it important to take antibiotics only when they're needed?

You should only take antibiotics when they are needed because they can cause side effects and can contribute to Antibiotic resistance infections. 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.

How do I use antibiotics correctly?

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

Antidepressants

What are antidepressants?

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.

Are antidepressants used for other conditions?

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

What are the different types of antidepressants?

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:

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.

Which type of antidepressant is right for me?

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:

How long do antidepressants take to work?

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.

How long will I need to take an antidepressant?

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.

What are the side effects of antidepressants?

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:

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.

What can I do to take antidepressants safely?

Antidepressants are generally safe when you use them correctly:

type 1 diabetestype 2 diabetes

What are the treatments for diabetes?

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.

Who needs diabetes medicines?

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.

What are the types of medicines for type 1 diabetes?

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.

What are the types of medicines for type 2 diabetes?

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.

What else should I know about taking medicines for diabetes?

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.

Drug Reactions

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.

What is a drug interaction?

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:

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

What are side effects?

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.

What are drug allergies?

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.

How can I stay safe when taking medicines?

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.
