Flunisolide is 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 to use Nasarel Spray, Non-Aerosol
Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. Follow the illustrated directions for the proper use of this medication. If you have any questions, ask your doctor or pharmacist.
This medication is for use in the nose, usually 1 or 2 sprays in each nostril 2 to 3 times a day or as directed by your doctor. Avoid spraying this medication in your eyes. Gently blow your nose before using this drug. Gently shake the container before each use. Follow the instructions to properly prime the spray pump if you are using it for the first time, or if you have not used it for 5 or more days, or if you have taken the pump apart to clean. Follow the instructions to clean the spray pump if needed.
To use the spray, first remove the safety clip and plastic cap. Close one nostril by pressing it with your finger. Tilt your head slightly forward and, keeping the bottle upright, carefully insert the nasal applicator into the other nostril. Press down firmly on the pump to deliver the prescribed number of sprays while gently breathing in through the nose, keeping your mouth closed. Do not spray directly onto the middle wall of your nose (nasal septum). After spraying, remove the applicator tip and tilt your head back for a few seconds. This will allow the medication to spread over the back of your nose. Repeat in the other nostril. Wipe the applicator tip and replace the plastic cap. Avoid blowing your nose for 15 minutes after using this medication.
Dosage is based on your medical condition and response to treatment. Younger children may need a smaller dose and help from an adult to use this medication properly. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Do not increase your dose or use it more frequently than directed.
This medication does not work right away. Some people will feel this medication working within 1 to 2 days, but it may take up to 2 weeks before the full benefit of this drug takes effect. Ask your doctor or pharmacist if you should also use other medications (such as nose drops/spray, allergy drugs taken by mouth) along with this drug until it takes full effect.
Keep track of the number of sprays used from the bottle. Discard the bottle after you have used the number of sprays specified on the manufacturer's package. Do not pour any remaining medication into another container. Follow the package instructions to unblock the spray tip if needed and to clean the spray bottle.
Tell your doctor if your condition does not improve after 3 weeks or if it worsens.
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.

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.

Though it is unlikely, this medication may temporarily slow down a child's growth if used for a long time. 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.
The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring.
