Rarely, using corticosteroid medications for a long time can make it more difficult for your body to respond to physical stress. Therefore, before having surgery or emergency treatment, or if you get a serious illness/injury, tell your doctor or dentist that you are using this medication or have used this medication within the past few months.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Though it is unlikely, this medication may slow down a child's growth if used for a long time. The effect on final adult height is unknown. See the doctor regularly so your child's height can be checked.
During pregnancy, this medication should be used only when clearly needed. Rarely, infants born to mothers who have been using corticosteroids (including flunisolide) for a long time may have low levels of corticosteroid hormone. Tell your doctor right away if you notice symptoms such as persistent nausea/vomiting, severe diarrhea, or weakness in your newborn. Discuss the risks and benefits with your doctor.
It is unknown if nasal flunisolide passes into breast milk. However, similar drugs pass into breast milk. Consult your doctor before breast-feeding.
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 serious side effects occur: loss 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. These side effects are more likely in children and people who use this medication for a long time and in high doses. 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).
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, wheezing/trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
