Pain Relievers

Pain relievers are medicines that reduce or relieve headaches, sore muscles, arthritis, or other aches and pains. There are many different pain medicines, and each one has advantages and risks. Some types of pain respond better to certain medicines than others. Each person may also have a slightly different response to a pain reliever.

Over-the-counter (OTC) medicines are good for many types of pain. There are two main types of OTC pain medicines: acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs). Aspirin, naproxen (Aleve), and ibuprofen (Advil, Motrin) are examples of OTC NSAIDs.

If OTC medicines don't relieve your pain, your doctor may prescribe something stronger. Many NSAIDs are also available at higher prescription doses. The most powerful pain relievers are opioids. They are very effective, but they can sometimes have serious side effects. There is also a risk of opioids. Because of the risks, you must use them only under a doctor's supervision.

There are many things you can do to help ease pain. Pain relievers are just one part of a pain treatment plan.

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:

Cold and Cough Medicines

What are cold and cough medicines?

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.

What are the different types of cold and cough medicines?

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

What do I need to know about taking cold and cough medicines?

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.

What else can I do to feel better for a cold or cough?

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

Fever

A fever is a body temperature that is higher than normal. A normal temperature can vary from person to person, but it is usually around 98.6 °F (37 °C). A fever is not a disease. It is usually a sign that your body is trying to fight an illness or infection.

Infections cause most fevers. You get a fever because your body is trying to kill the virus or bacteria that caused the infection. Most of those bacteria and viruses do well when your body is at your normal temperature. But if you have a fever, it is harder for them to survive. Fever also activates your body's immune system.

Other causes of fevers include:

Treatment depends on the cause of your fever. If the fever is very high, your health care provider may recommend taking an over-the-counter medicine such as acetaminophen or ibuprofen. Adults can also take aspirin, but children with fevers should not take aspirin. It is also important to drink enough liquids, to prevent dehydration.

Opioid Overdose

What are opioids?

Opioids, sometimes called narcotics, are a type of drug. They include strong prescription pain relievers such as oxycodone, hydrocodone, fentanyl, and tramadol. The illegal drug heroin is also an opioid.

A health care provider may give you a prescription opioid to reduce pain after you have had a major injury or surgery. You may get them if you have severe pain from health conditions like cancer. Some providers prescribe them for chronic pain.

Prescription opioids used for pain relief are generally safe when taken for a short time and as prescribed by your provider. However, people who take opioids are at risk for opioid use disorder (OUD) and overdose. These risks increase when these medicines are misused. Misuse can include taking more than your prescribed dose or taking it more often, using it to get high, or taking someone else's opioids.

What is an opioid overdose?

Opioids affect the part of the brain that regulates breathing. When people take high doses of opioids, it can lead to an overdose, with the slowing or stopping of breathing and sometimes death.

What causes an opioid overdose?

An opioid overdose can happen for a variety of reasons, including if you:

There is also a risk of overdose if you are getting medications for opioid use disorder (MOUD). MOUD is a treatment for OUD. Many of the medicines used for MOUD are also controlled substances that can be misused.

Who is at risk of an opioid overdose?

Anyone who takes an opioid can be at risk of an overdose, but you are at higher risk if you:

What are the signs of an opioid overdose?

The signs of an opioid overdose include:

What should I do if I think that someone is having an opioid overdose?

If you think someone is having an opioid overdose:

Naloxone won't harm someone if they're overdosing on drugs other than opioids, so it's best to use it if you think someone is overdosing.

Can an opioid overdose be prevented?

If you are taking opioid pain medicine, there are steps you can take to help prevent an opioid overdose:

It is also important to teach your family and friends how to respond to an overdose. If you are at higher risk of an overdose, you will want get naloxone and carry it with you wherever you go. You can buy naloxone at a pharmacy.

Opioids and Opioid Use Disorder (OUD)

What are opioids?

Opioids, sometimes called narcotics, are a type of drug. They include strong prescription pain relievers such as oxycodone, hydrocodone, fentanyl, and tramadol. The illegal drug heroin is also an opioid. Some opioids are made from the opium plant, and others are synthetic (man-made).

A health care provider may give you a prescription opioid to reduce pain after you have had a major injury or surgery. You may get them if you have severe pain from health conditions like cancer. Some providers prescribe them for chronic pain.

What are the side effects and risks of opioids?

Opioids can cause side effects such as drowsiness, mental fog, nausea, and constipation. They may also cause slowed breathing, which can lead to overdose deaths. If someone has signs of an overdose, call 911. These signs may include:

When using opioids, there is also a risk of opioid use disorder (OUD).

What is opioid use disorder (OUD)?

Opioid use disorder (OUD) means that you have a problematic pattern of using opioids. The pattern causes a lot of distress and impairment (meaning that it causes problems in and interferes with your daily life). Instead of OUD, sometimes people use the terms "opioid dependence" and "opioid addiction." Dependence means feeling withdrawal symptoms when not taking the drug. Addiction is a chronic brain disease that causes a person to compulsively seek out drugs, even though they cause harm.

The risk of OUD is higher if you misuse the medicines. Misuse can include taking more than your prescribed dose or taking it more often, using it to get high, or taking someone else's opioids.

Opioid use disorder and overdoses are serious public health problems in the United States. As more people misuse opioids, more women are misusing opioids during pregnancy. This can lead to health risks for the mother and baby. The baby may be born with neonatal abstinence syndrome (NAS). NAS is a group of withdrawal symptoms that a baby has after being exposed to drugs during pregnancy.

Another problem with increased opioid misuse is that it can also lead to more heroin use. There are some people who switch from prescription opioids to heroin because heroin may be cheaper and easier to get.

How are opioid use disorder (OUD) and opioid overdose treated?

There are effective medicines to treat OUD. Using medicines to treat OUD is called medications for opioid use disorder (MOUD). MOUD can help you stop using the drug, get through withdrawal, and cope with cravings. It is often combined with behavioral therapy and counseling. Having support from family and friends can also help.

There is also a medicine called naloxone which can treat opioid overdoses. It can reverse the effects of the overdose and prevent death if it is given quickly.

How can I prevent problems when taking prescription opioids?

To prevent problems with prescription opioids, be sure to follow your doctor's instructions when taking them. Do not share your medicines with anyone else. Contact your doctor if you have any concerns about taking the medicines.

Over-the-Counter Medicines

Over-the-counter (OTC) medicines are drugs you can buy without a prescription. Some OTC medicines relieve aches, pains, and itches. Some prevent or cure diseases, like tooth decay and athlete's foot. Others help manage recurring problems, like migraines and allergies.

In the United States, the Food and Drug Administration decides whether a medicine is safe and effective enough to sell over-the-counter. This allows you to take a more active role in your health care. But you also need to be careful to avoid mistakes. Make sure to follow the instructions on the drug label. If you don't understand the instructions, ask your pharmacist or health care provider.

Also keep in mind that that there are still risks to taking OTC medicines:

If you have been taking an OTC medicine but your symptoms don't go away, contact your health care provider. You should not take OTC medicines longer or in higher doses than the label recommends.

Acute Bronchitis

Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. It causes a cough that often brings up mucus. It can also cause shortness of breath, wheezing, a low fever, and chest tightness. There are two main types of bronchitis: acute and chronic.

Most cases of acute bronchitis get better within several days. But your cough can last for several weeks after the infection is gone.

The same viruses that cause colds and the flu often cause acute bronchitis. These viruses spread through the air when people cough, or though physical contact (for example, on unwashed hands). Being exposed to tobacco smoke, air pollution, dusts, vapors, and fumes can also cause acute bronchitis. Less often, bacteria can also cause acute bronchitis.

To diagnose acute bronchitis, your health care provider will ask about your symptoms and listen to your breathing. You may also have other tests.

Treatments include rest, fluids, and aspirin (for adults) or acetaminophen to treat fever. A humidifier or steam can also help. You may need inhaled medicine to open your airways if you are wheezing. Antibiotics won't help if the cause is viral. You may get antibiotics if the cause is bacterial.

Chickenpox

Chickenpox is an infection caused by the varicella-zoster virus. Most cases are in children under age 15, but older children and adults can get it. It spreads very easily from one person to another.

The classic symptom of chickenpox is an uncomfortable, itchy rash. The rash turns into fluid-filled blisters and eventually into scabs. It usually shows up on the face, chest, and back and then spreads to the rest of the body. Other symptoms include:

Chickenpox is usually mild and lasts 5 to 10 days. Calamine lotions and oatmeal baths can help with itching. Acetaminophen can treat the fever. Do not use aspirin for chickenpox; that combination can cause Reye syndrome.

Chickenpox can sometimes cause serious problems. Adults, babies, teenagers, pregnant women, and those with weak immune systems tend to get sicker from it. They may need to take antiviral medicines.

Once you catch chickenpox, the virus usually stays in your body. You probably will not get chickenpox again, but the virus can cause shingles in adults. A chickenpox vaccine can help prevent most cases of chickenpox, or make it less severe if you do get it.

Dengue

What is dengue?

Dengue is a viral infection. It can be caused by four related viruses. You can get it if an infected mosquito bites you. It is common in warm, wet areas of the world. Although rare, it can be found in some parts of the United States. Outbreaks are more common during rainy seasons.

How does dengue spread?

Dengue spreads to people through the bite of an infected mosquito. It does not spread directly from person to person. However, a pregnant person can pass the infection on to the baby. In rare cases, it can spread through a blood transfusion, organ transplant, or needle stick injury (an accidental injury from a used needle)..

What are the symptoms of dengue and severe dengue?

About one in four people infected with dengue will get sick. For those who do get sick, the infection can be mild or severe. The symptoms of dengue include:

The symptoms usually last two to seven days.

Severe dengue is a serious form of the illness. About 1 in 20 people who get sick with dengue will develop severe dengue. It can cause shock, internal bleeding, and even death. People are more likely to develop severe dengue if they have had dengue before, are pregnant, or are infants.

Watch for signs and symptoms of severe dengue. Warning signs usually begin about 24 - 48 hours after your fever has gone away. If you or your family member have these signs, get immediate medical care:

How is dengue diagnosed?

There is a blood test which can show if you have been infected with dengue.

What are the treatments for dengue?

There is no specific medicine to treat dengue. Most people will get better after about a week. But if you think you might have dengue:

Severe dengue often requires care at a hospital.

Can dengue be prevented?

In the United States, a dengue vaccine is approved for children who are ages 9 - 16. They must also have previously had dengue and live in areas where dengue is common.

You can also help prevent dengue by avoiding mosquito bites:
