Pseudoephedrine is used to relieve nasal congestion caused by colds, allergies, and hay fever. It is also used to temporarily relieve sinus congestion and pressure. Pseudoephedrine will relieve symptoms but will not treat the cause of the symptoms or speed recovery. Pseudoephedrine is in a class of medications called nasal decongestants. It works by causing narrowing of the blood vessels in the nasal passages.

Pseudoephedrine comes as a regular tablet, a 12-hour extended-release (long-acting) tablet, a 24-hour extended-release tablet, and a solution (liquid) to be taken by mouth. The regular tablets and liquid are usually taken every 4 to 6 hours. The 12-hour extended-release tablets usually are taken every 12 hours, and you should not take more than two doses in a 24-hour period. The 24-hour extended-release tablets usually are taken once a day, and you should not take more than one dose in a 24-hour period. To help prevent trouble sleeping, take the last dose of the day several hours before bedtime. Follow the directions on the package label or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pseudoephedrine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor or directed on the label.

Pseudoephedrine comes alone and in combination with other medications. Ask your doctor or pharmacist for advice on which product is best for your symptoms. Check nonprescription cough and cold product labels carefully before using 2 or more products at the same time. These products may contain the same active ingredient(s) and taking them together could cause you to receive an overdose. This is especially important if you will be giving cough and cold medications to a child.

Nonprescription cough and cold combination products, including products that contain pseudoephedrine, can cause serious side effects or death in young children. Do not give nonprescription pseudoephedrine products to children younger than 4 years of age. If you give these products to children 4-11 years of age, use caution and follow the package directions carefully. Do not give pseudoephedrine extended-release tablets to children younger than 12 years of age.

If you are giving pseudoephedrine or a combination product that contains pseudoephedrine to a child, read the package label carefully to be sure that it is the right product for a child of that age. Do not give pseudoephedrine products that are made for adults to children.

Before you give a pseudoephedrine product to a child, check the package label to find out how much medication the child should receive. Give the dose that matches the child's age on the chart. Ask the child's doctor if you don't know how much medication to give the child.

If you are taking the liquid, do not use a household spoon to measure your dose. Use the measuring spoon or cup that came with the medication or use a spoon made especially for measuring medication.

If your symptoms do not get better within 7 days or if you have a fever, stop taking pseudoephedrine and call your doctor.

Swallow the extended-release tablets whole; do not break, crush, or chew them.

This medication is also sometimes used to prevent ear pain and blockage caused by pressure changes during air travel or underwater diving. Talk to your doctor or pharmacist for more information.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking pseudoephedrine,

  • tell your doctor and pharmacist if you are allergic to pseudoephedrine, any other medications, or any of the inactive ingredients in the pseudoephedrine product you plan to take. Check the package label for a list of the ingredients.
  • do not take pseudoephedrine if you are taking a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate), or if you have stopped taking one of these medications within the past 2 weeks.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention medications for diet or appetite control, asthma, colds, or high blood pressure.
  • tell your doctor if you have or have ever had high blood pressure, glaucoma (a condition in which increased pressure in the eye can lead to gradual loss of vision), diabetes, difficulty urinating (due to an enlarged prostate gland), or thyroid or heart disease. If you plan to take the 24-hour extended-release tablets, tell your doctor if you have had a narrowing or blockage of your digestive system.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking pseudoephedrine, call your doctor.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking pseudoephedrine.

Foods and drinks that contain large amounts of caffeine can make the side effects of pseudoephedrine worse.

This medication is usually taken as needed. If your doctor has told you to take pseudoephedrine regularly, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

If you are taking the 24-hour extended-release tablets, you may notice something that looks like a tablet in your stool. This is just the empty tablet shell, and this does not mean that you did not get your complete dose of medication.

Ask your pharmacist any questions you have about pseudoephedrine.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

Sudafed: What You Need to Know

We include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process.


If you’re stuffed up and looking for relief, Sudafed is one medication that could help. Sudafed helps relieve nasal and sinus congestion and pressure due to the common cold, hay fever, or upper respiratory allergies.

Here’s what you need to know to use this drug safely to relieve your congestion.

About Sudafed

The main active ingredient in Sudafed is called pseudoephedrine (PSE). It’s a nasal decongestant. PSE relieves congestion by making the blood vessels in your nasal passages narrower. This opens up your nasal passages and allows your sinuses to drain. As a result, your nasal passages are clearer and you breathe more easily.

Most forms of Sudafed only contain pseudoephedrine. But one form, called Sudafed 12 Hour Pressure + Pain, also contains the active drug naproxen sodium. Any additional side effects, interactions, or warnings caused by naproxen sodium are not covered in this article.

Sudafed PE products don’t contain pseudoephedrine. Instead, they contain a different active ingredient called phenylephrine.


All forms of Sudafed are taken by mouth. Sudafed Congestion, Sudafed 12 Hour, Sudafed 24 Hour, and Sudafed 12 Hour Pressure + Pain come as caplets, tablets, or extended-release tablets. Children’s Sudafed comes in liquid form in grape and berry flavors.

Below are dosage instructions for the different kinds of Sudafed. You can also find this information on the medication’s package.

Sudafed Congestion

  • Adults and children 12 years and older: Take two tablets every four to six hours. Do not take more than eight tablets every 24 hours.
  • Children ages 6–11 years: Take one tablet every four to six hours. Do not take more than four tablets every 24 hours.
  • Children younger than 6 years: Do not use this medication for children younger than 6 years.

Sudafed 12 Hour

  • Adults and children 12 years and older. Take one tablet every 12 hours. Do not take more than two tablets every 24 hours. Do not crush or chew the caplets.
  • Children younger than 12 years. Do not use this medication for children younger than 12 years.

  • Children younger than 12 years. Do not use this medication for children younger than 12 years.

  • Children younger than 12 years. Do not use this medication for children younger than 12 years

  • Children ages 4–5 years. Give 1 teaspoon every four to six hours. Do not give more than four doses every 24 hours.
  • Children younger than 4 years. Do not use this medication for children younger than 4 years.

Side effects

Like most drugs, Sudafed may cause side effects. Some of these side effects may go away as your body gets used to the medication. If any of these side effects are a problem for you or if they don’t go away, call your doctor.

More common side effects

The more common side effects of Sudafed can include:

  • weakness or dizziness
  • restlessness
  • headache
  • nausea
  • insomnia

Serious side effects

The rare but serious side effects of Sudafed can include:

  • very fast heart rate
  • trouble breathing
  • hallucinations (seeing or hearing things that aren’t there)
  • psychosis (mental changes that cause you to lose touch with reality)
  • heart problems, such as chest pain, increased blood pressure, and irregular heartbeat
  • heart attack or stroke

Drug interactions

Sudafed may interact with other medications you’re taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well. Talk to your pharmacist or doctor to see if Sudafed interacts with any medications you’re currently taking.

You should not take the following drugs with Sudafed:

  • dihydroergotamine
  • rasagiline
  • selegiline

Also, before taking Sudafed, be sure to tell your doctor if you take any of the following medications:

  • blood pressure or heart medications
  • asthma medications
  • migraine medications
  • antidepressants
  • over-the-counter herbal remedies, such as St. John’s Wort


There are a few warnings you should keep in mind if you take Sudafed.

Conditions of concern

Sudafed is safe for many people. However, you should avoid it if you have certain health conditions, which may get worse if you take Sudafed. Before using Sudafed, be sure to tell your doctor if you have:

Other warnings

There are concerns of misuse with Sudafed because it can be used to make illegal methamphetamine, a very addictive stimulant. However, Sudafed itself is not addictive.

There are also no warnings against drinking alcohol while taking Sudafed. However, in rare cases, alcohol may increase certain side effects of Sudafed, such as dizziness.

If you’ve taken Sudafed for a week and your symptoms don’t go away or get better, call your doctor. Also call if you have a high fever.

In case of overdose

Symptoms of an overdose of Sudafed can include:

  • fast heart rate
  • dizziness
  • anxiety or restlessness
  • increased blood pressure (likely without symptoms)
  • seizures

If you think you’ve taken too much of this drug, call your doctor or local poison control center. If your symptoms are severe, call 911 or go to the nearest emergency room right away.

Prescription status and restrictions

In most states, Sudafed is available over the counter (OTC). However, some locations in the United States require a prescription. The states of Oregon and Mississippi, as well as some cities in Missouri and Tennessee, all require a prescription for Sudafed.

The reason for these prescription requirements is that PSE, the main ingredient in Sudafed, is used to make illegal methamphetamine. Also called crystal meth, methamphetamine is a highly addictive drug. These requirements help prevent people from buying Sudafed to make this drug.

Efforts to prevent people from using PSE to make methamphetamine also restrict the sale of Sudafed. A piece of legislation called the Combat Methamphetamine Epidemic Act (CMEA) was passed in 2006. It requires you to present a photo ID to buy products that contain pseudoephedrine. It also limits the amount of these products you can buy.

In addition, it requires pharmacies to sell any products that contain PSE behind the counter. That means you can’t buy Sudafed on the shelf at your local drugstore like other OTC medications. You have to get Sudafed from the pharmacy. You also have to show your photo ID to the pharmacist, who is required to track your purchases of products that contain PSE.
