Uses

What is Flunisolide used for?

Flunisolide is commonly used to prevent and treat seasonal and year-round allergy symptoms (such as stuffy/runny nose, itchy eyes/nose/throat, sneezing). Flunisolide belongs to a class of drugs known as corticosteroids. It works by reducing swelling (inflammation) in the nasal passages.

How should I take Flunisolide?

Temporary nose/throat dryness or irritation, cough, nosebleeds, sneezing and unpleasant taste/smell may occur. If any of these side effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if any of these rare but seriousloss of taste or smell, pain/sores in your nose.

Rarely, it is possible that corticosteroids given in the nose will be absorbed into the bloodstream. This can lead to side effects of too much corticosteroid.

Tell your doctor right away if any of the following side effects occur: unusual/extreme tiredness, weight loss, headache, swelling ankles/feet, increased thirst/urination, vision problems.

Corticosteroids may weaken the body’s ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. This effect might also rarely occur with corticosteroids inhaled through the nose (such as flunisolide). The risk may be increased if high doses are used, especially when used for a long time. Tell your doctor right away if you have any signs of infection (such as ear pain, persistent sore throat, fever, chills, white patches inside the nose or on the back of the throat).
