What is Nexafed?
Nexafed is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
Nexafed is used to treat nasal and sinus congestion, or congestion of the tubes that drain fluid from your inner ears, called the eustachian (yoo-STAY-shun) tubes.
Nexafed may also be used for purposes not listed in this medication guide.
Always ask a doctor before giving a cough or cold medicine to a child.

How should I take Nexafed?
Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Cold medicine is usually taken only for a short time until your symptoms clear up.
Do not give this medication to a child younger than 4 years old. Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

Do not crush, chew, or break an extended-release tablet. Swallow it whole.
You may need to shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
If you need surgery, tell the surgeon ahead of time that you are using Nexafed. You may need to stop using the medicine for a short time.
Store at room temperature away from moisture and heat. Protect the liquid medicine from light, and do not allow it to freeze.
What happens if I miss a dose?
Since Nexafed is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include hallucinations, slow heartbeats, or seizure (convulsions).
What should I avoid while taking Nexafed?
Avoid taking this medication if you also take diet pills, caffeine pills, or other stimulants (such as ADHD medications). Taking a stimulant together with a decongestant can increase your risk of unpleasant side effects.
Ask a doctor or pharmacist before using any other cough or cold medicine. Many combination medicines contain Nexafed or another decongestant. Taking certain products together can cause you to get too much of this type of medicine.
