Phenylephrine nasal spray is a decongestant. It's used to treat nasal and sinus congestion in children and adults. The typical dose is 2 or 3 sprays every 4 hours, but for no longer than 3 days. It's typically well-tolerated, but some people might experience temporary side effects, such as stinging or sneezing, right after each spray. Phenylephrine nasal spray is available as brand name (e.g., Neo-Synephrine) and generic medications.

Increase in runny or stuffy nose
Symptoms of too much medicine being absorbed into the body
Fast, irregular, or pounding heartbeat
headache or dizziness
increased sweating
nervousness
paleness
trembling
trouble in sleeping
Note: The above side effects are more likely to occur in children because there is a greater chance that too much of this medicine may be absorbed into the body.

Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects.

Burning, dryness, or stinging of inside of nose

Can't be used for longer than 3 days due to the risk of rebound congestion

You might feel temporary discomforts, such as stinging or sneezing, right after using phenylephrine nasal spray. These side effects are typically mild and go away after a while. But if they're bothersome and don't go away, let your primary care provider (PCP) know because you might need to stop using this spray.
If phenylephrine nasal spray isn't enough to ease your congestion, ask a member of your care team about other nasal sprays, such as fluticasone (Flonase) or sodium chloride (Ocean Nasal Spray). These medications work differently than phenylephrine nasal spray and your care team can talk with you about other available options to help with your symptoms.
If you're pregnant, don't use phenylephrine nasal spray until you've talked with your obstetrician-gynecologist (OB-GYN) to understand the risks and benefits of this medication. There's not much research looking into how phenylephrine nasal spray might affect pregnancy, but evidence suggests oral decongestants can cause harm. Your care team can talk with you about safer options to treat your symptoms during pregnancy.
Tips on how to use phenylephrine nasal sprays:
Before using phenylephrine nasal spray, blow your nose and wash your hands with soap and water. Shake the bottle gently before each use and remove the cap. Press down one nostril with your index finger to close it. Tilt your head slightly forward and place the tip of the bottle into the other nostril aiming towards the back of your head. For each dose, squeeze the bottle with firm, quick pressure while breathing in.
It's normal for some of the spray or drops to drip out your nose after each dose. Don't give yourself or your child any additional sprays or drops than what's recommended to try to replace what drips out. You might accidentally use too much medication and put yourself or your child at higher risk for side effects.
Always clean the tip of the bottle after each use. Don't share phenylephrine nasal spray with other people to avoid spreading infections.
Stop using phenylephrine nasal spray if you feel nervous or dizzy, or if you can't sleep after using this medication. Ask your primary care provider for other options to help with your congestion.
Phenylephrine nasal spray is a decongestant, which are in many other over-the-counter medications. Using more than one medication containing a decongestant, including oral forms, can cause serious side effects, such as fast heart rate and dizziness. If you're not sure if a product has a decongestant, ask your pharmacist.
Phenylephrine nasal spray can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
While phenylephrine is available in forms that can be taken by mouth, phenylephrine nasal spray should only be used in your nose. Don't give yourself or your child this medication any other way. If you feel a nasal spray isn't the best choice for you, ask your pharmacist or primary care provider for other options to treat your congestion. If you or someone else takes phenylephrine nasal spray by mouth, get medical help right away or contact a poison control center at 1-800-222-1222.
