Decongestants

Decongestants may help shrink swollen tissues in the nose, sinuses, and throat and the space behind the eardrum (middle ear). This may relieve pressure, pain, and stuffiness (congestion).

Decongestants can be taken by mouth as a pill or liquid (oral). Or they can be used as nose drops, sprays, or gels. Sprays and drops provide rapid relief, but they should only be used for 2 to 3 days. Oral decongestants may cause more side effects than the ones used in the nose, but they can be taken for up to 7 days.

To know if an over-the-counter medicine contains a decongestant, check the label for the active ingredient. Examples of decongestants are:

• Oxymetazoline (such as in Afrin or Zicam Extreme Congestion Relief).
• Phenylephrine (such as in Neo-Synephrine or Sudafed PE).
• Pseudoephedrine (such as in Sudafed).

In some states, any medicine that contains pseudoephedrine is kept behind the pharmacist's counter so you will need to ask the pharmacist for it. In other states, you have to have a prescription from your doctor to buy medicine containing pseudoephedrine.

Cautions for decongestants include the following.

• Decongestants may not be safe for young children. The U.S. Food and Drug Administration (FDA) recommends not using over-the-counter cough and cold medicines in children younger than age 2. The FDA also recommends avoiding these medicines for children younger than age 4. If you use these medicines, always follow the directions about how much to use based on age and, in some cases, weight.
• Decongestants can cause problems for people who have certain health problems, such as heart disease, high blood pressure, glaucoma, diabetes, or an overactive thyroid. Decongestants may also interact with some drugs, such as certain antidepressants and high blood pressure medicines. Read the package carefully or ask your pharmacist or doctor to help you choose the best decongestant for you.
• Don't use decongestant nasal sprays, drops, or gels more times in one day or for more days in a row than the label says. Overuse can cause rebound congestion. It makes your mucous membranes swell up more than before you used the spray.
• If you are pregnant or breastfeeding, check with your doctor or pharmacist before you use a decongestant.
