Flunisolide - oral inhalation
Flunisolide - oral inhalation
Flunisolide is used to prevent and control symptoms (wheezing and shortness of breath) caused by asthma. This medication belongs to a class of drugs known as corticosteroids. It works directly in the lungs to make breathing easier by reducing the irritation and swelling of the airways.
This medication must be used regularly to prevent breathing problems (attacks of wheezing/shortness of breath). It does not work right away and should not be used to relieve an asthma attack. If an attack occurs, use your quick-relief inhaler as prescribed.
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 for lung diseases such as bronchitis and emphysema.
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, consult your doctor, pharmacist, or respiratory therapist.
Shake the canister well before each use. Inhale this medication by mouth, usually 2 times a day or as directed by your doctor. The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on age.
If 2 or more inhalations/puffs for each dose are prescribed, wait at least 1 minute between them. Shake the canister well between each puff.
If you are using other inhalers at the same time, wait at least 1 minute between the use of each medication, and use this drug (the corticosteroid) last.
To prevent dry mouth, hoarseness, and fungal infection of the mouth, rinse your mouth with water after each use. Do not swallow the rinse water.
Use this medication exactly as prescribed. Follow the dosing schedule carefully. If you have any questions, ask your doctor or pharmacist.
Keep track of the number of inhalations used. Discard the canister after using the labeled number of inhalations on the package, even if it feels as though there is medication left in the canister. Follow the instructions for cleaning the mouthpiece. Do not wash the metal canister or put any part of it in water.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time(s) each day. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Learn which of your inhalers you should use every day (controller drugs) and which you should use if your breathing suddenly worsens (quick-relief drugs). Ask your doctor ahead of time what you should do if you have new or worsening cough or shortness of breath, wheezing, increased sputum, worsening peak flow meter readings, waking up at night with trouble breathing, if you use your quick-relief inhaler more often (more than 2 days a week), or if your quick-relief inhaler does not seem to be working well. Learn when you can treat sudden breathing problems by yourself and when you must get medical help right away.
If you are regularly taking a different corticosteroid by mouth (such as prednisone), you should not stop taking it unless directed by your doctor. Some conditions (such as asthma, allergies) may become worse when the drug is suddenly stopped. If you suddenly stop taking the drug, you may also have withdrawal symptoms (such as weakness, weight loss, nausea, muscle pain, headache, tiredness, dizziness). To help prevent withdrawal, your doctor may slowly lower the dose of your old medication after you begin using flunisolide. Tell your doctor or pharmacist right away if you have withdrawal. See also Precautions section.
You may begin to feel this medication working within a week, but it may take 4 weeks before the full benefit of this drug takes effect. Tell your doctor if your condition does not improve or if it worsens.
See also Precautions section.
Dry/sore throat, hoarseness, a bad taste in the mouth, headache, or voice changes may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Infrequently, this medication may cause severe sudden worsening of breathing problems/asthma immediately after use. If you have sudden worsening of breathing, use your quick-relief inhaler and seek immediate medical attention.
Because this drug works by weakening the immune system, it may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as ear pain, sore throat, fever, chills). Use of this medication for prolonged or repeated periods may result in oral thrush (yeast infection). Contact your doctor if you notice white patches in your mouth or on your tongue.
Tell your doctor right away if any of these rare but very serious side effects occur:
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:

If you have switched from a corticosteroid taken by mouth (such as prednisone tablets) to this inhaler within the past 12 months, or if you have been using this product in higher-than-usual doses for a long time, it may be 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 a corticosteroid taken by mouth within the past 12 months. Tell your doctor right away if you develop unusual/extreme tiredness or weight loss. Carry a warning card or medical ID bracelet that says you use (or have used) corticosteroid medications.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
This medication may mask signs of infection. It can make you more likely to get infections or may worsen any current infections. Therefore, wash your hands well to prevent the spread of infection. Avoid contact with people who have infections that may spread to others (such as chickenpox, measles, flu). Consult your doctor if you have been exposed to an infection or for more details.
Flunisolide may cause vaccines not to work as well. Therefore, do not have any immunizations/vaccinations while using this medication without the consent of your doctor. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).

Lifestyle changes that reduce the risk of bone loss include doing weight-bearing exercise, getting enough calcium and vitamin D, stopping smoking, and limiting alcohol. To help prevent osteoporosis later in life, encourage children to exercise and eat a healthy diet (including calcium).
