Decongestant spray - nasal
Nasal Four 1 % spray
This medication is used for temporary relief of congestion in the nose caused by various conditions including the common cold, sinusitis, hay fever, and allergies. It works by narrowing the blood vessels in the nose area, reducing swelling and congestion.
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
This drug may also be used to relieve "plugged ears" and to reduce swelling in the nose before certain surgery or procedures.
Use this medication in the nose as directed. Follow all directions on the product package, or use as directed by your doctor. If you have any questions, ask your doctor or pharmacist.
Gently blow your nose before using this drug. Use your finger to close the nostril on the side not receiving the medication. While keeping your head upright, place the spray tip into the open nostril. Spray the medication into the open nostril as you breathe in through your nose. Sniff hard a few times to be sure the medication reaches deep into the nose. Repeat these steps for the other nostril if needed.
Avoid spraying the medication into your eyes or onto the middle of the inside of your nose (nasal septum).
Rinse the spray tip with hot water or wipe with a clean tissue after each use. Make sure that water does not get inside the container. Replace cap after each use.
This medication provides only temporary relief. Do not use more often, use more sprays, or use longer than directed because doing so may increase the risk of side effects. Also, do not use this medication for more than 3 days or it may cause a condition called rebound congestion. Symptoms of rebound congestion include long-term redness and swelling inside the nose and increased runny nose. If this occurs, stop using this medication and consult your doctor or pharmacist.
Inform your doctor if your condition worsens or persists after 3 days.
Temporary burning, stinging, dryness in the nose, runny nose, and sneezing may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
