Pharmacist tips for Flunisolide

pharmacist
  • Follow the directions on how to use nasal sprays like flunisolide. Ask a healthcare professional if you have specific questions on how to use the flunisolide nasal spray.

    • Before you use a new bottle of flunisolide for the first time, you'll need to prime it. This means spraying 5 to 6 times into the air, or until you see a fine spray of medication come out of the nozzle tip. Priming the spray bottle makes sure you get a full dose of medication when you spray it into your nose.

      • Prime the bottle of flunisolide if you haven't used it for at least 5 days. Also prime the spray bottle after each time you've taken it apart to clean it.

        • Blow your nose gently before you use flunisolide. When you're ready, remove the dust cover. Insert the nozzle tip in one nostril and press close the other with a finger. Tilt your head forward a little. Then, spray towards the back and outer side of the nostril as you gently sniff at the same time. Tilt your head back to let the medication spread over the back of your nostril. Follow the same steps for the other nostril.

          • Avoid spraying flunisolide into your eyes. It can cause bothersome irritation.

            • Flunisolide can cause mild burning or stinging in your nose after you spray the medication into the nostril. This feeling should go away after a short while. Call a healthcare professional if the irritation is bothersome, if you get a nosebleed, or if your allergies get worse.

              • If the flunisolide spray nozzle gets clogged, don't use a sharp object to unplug it. This could damage the nozzle. Instead, take off the pump unit from the bottle and soak the pump in warm water. Squirt several times under the water. Let the pump unit dry before you put the spray bottle back together. Spray 5 or 6 times away from yourself before you use the medication again to make sure you get your full dose.

                • Tell your prescriber if you've been around someone with chickenpox or measles. This is especially important if you haven't been vaccinated or if you haven't had these infections before. Steroids like flunisolide can weaken your immune system and make it easier for you to get sick. Your prescriber can suggest ways to help protect you from serious infection.

                  faqs

                  Frequently asked questions about Flunisolide

                  Is flunisolide a steroid?
                  Yes, flunisolide is a steroid. This steroid medication comes as a nasal spray. You spray flunisolide into the nose to lower inflammation and irritation in the nose due to allergies. This helps treat congestion, runny nose, and other nasal symptoms of allergies.
                  Is flunisolide over the counter?
                  No. Flunisolide isn't available over the counter (OTC). You have to get a prescription for the flunisolide nasal spray from a healthcare professional. Ask a pharmacist if you're looking for an OTC nasal spray that can help with allergies. They can recommend one that best fits your needs.
                  Is flunisolide the same as Flonase?
                  No. Flunisolide and Flonase are different steroid nasal sprays that treat allergy symptoms of the nose, like runny nose and sneezing. Flunisolide is only available with a prescription from a healthcare professional. It's approved for people 6 years and older. But you can find Flonase and its generic version called fluticasone over the counter (OTC). Children can use Flonase, though the specific age depends on the Flonase product. Some Flonase products can be used in people as young as 2 years of age. Ask a healthcare professional about comparing between these two medications.
                  How long does it take flunisolide to start working?
                  In clinical studies, most people noticed symptom improvement within a few days after they start using flunisolide regularly. But it might take 1 to 2 weeks of regular use for you to feel the full effects of the medication. Contact your primary care provider if your symptoms don't improve after 3 weeks of using flunisolide every day. You might need a different medication to treat your allergy symptoms.
                  Can I use flunisolide as needed?
                  Flunisolide works best when you use it every day until your primary care provider says it's okay to stop. The medication helps lower inflammation in your nose. This helps relieve allergy symptoms while you're around things that trigger your allergies. If you'd rather use an allergy medication only when needed, talk to your primary care provider about your options.
                  Is flunisolide nasal spray being discontinued?
                  No. Generic flunisolide nasal spray is still available at pharmacies, even though all brand-name versions of the medication are discontinued. Sometimes, the pharmacy might not have the flunisolide nasal spray in stock when you need it. But they can order it for you.

                  What are the risks and warnings for Flunisolide?

                  Flunisolide can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                  risk-warning

                  Changes in stress hormone levels

                  • Risk factors: Using flunisolide for a long period of time | Using too much flunisolide | Starting flunisolide after long-term treatment with steroid pills | Also taking prednisone every other day

                    Using the flunisolide nasal spray for long periods of time or using too much of it can cause more medication to get absorbed into the body. This medication acts like a natural stress hormone in your body called cortisol. When too much medication gets absorbed into the body, your cortisol levels can get too high. Symptoms of high cortisol levels include weight gain around your gut, fatty deposits in the face and upper back, and tiredness.

                    Using too much flunisolide can also cause your body to make less of its own cortisol. This can make it harder for your body to respond to physical stress. Symptoms of low cortisol levels include muscle weakness, muscle or joint pain, and loss of appetite.

                    Let your prescriber know if you experience any of these symptoms so you can get proper treatment. To avoid large changes in your hormone levels, it's best to use the lowest dose of flunisolide possible for the shortest amount of time.

                    risk-warning

                    Risk of infection

                    • Risk factors: Long-term use of flunisolide | Untreated fungal, bacterial, or viral infection | Active or latent tuberculosis (TB) infection | Viral eye infection | Taking other medications that weaken your immune system

                      Flunisolide might affect your immune system's ability to fight infections. This can make it easier for you to get sick. In clinical studies, a few people who used flunisolide developed a type of fungal infection called thrush in the nose and throat. Other bacterial, fungal, and viral infections are possible, especially if you're taking other medications that can weaken your immune system.

                      Talk to a healthcare professional if you notice pain in the nose and throat with redness and white patches (a sign of thrush), fever, or other signs of infection while you're using the flunisolide nasal spray. You might need other treatment for the infection or have to stop using the flunisolide nasal spray.

                      risk-warning

                      Slowed wound healing

                      • Risk factors: Nasal surgery | Injury to the nose | Frequent nosebleeds | Ulcers in the nose

                        Steroid medications like flunisolide can slow your body's ability to heal wounds. Since this medication is directly sprayed into the nose, it can affect how long it takes for wounds in the nose to get better.

                        Be careful using flunisolide if you've had recent surgery in your nose, have nosebleeds that keep coming back, or have a nose injury. Your prescriber might recommend that you wait until the wound heals completely before you start using flunisolide.

                        risk-warning

                        Delayed growth in children

                        • Risk factors: Higher dose of flunisolide | Long-term use

                          Children who use steroid nasal sprays like flunisolide might have slower growth. It's not known how this slowed growth rate might affect their final adult height in the long run.

                          To lower the risk for slowed growth, your child's primary care provider or pediatrician will prescribe the lowest possible flunisolide dose that helps with their allergy symptoms. The healthcare professional will also keep track of your child's growth at follow-up visits. Talk to your child's primary care provider or pediatrician if you're concerned about how flunisolide might affect your child's growth.

                          Typical dosing for Flunisolide

                          Each spray contains 25 mcg of flunisolide.

                          • Adults and children 15 years and older: The typical starting dose is 2 sprays in each nostril twice a day. Your primary care provider might raise the dose to 2 sprays in each nostril three times a day if you need more relief. Don't use more than 8 sprays in each nostril in a day.

                          • Children age 6 to 14 years old: The typical starting dose is 1 spray in each nostril three times a day. Another option is 2 sprays in each nostril twice a day. Don't use more than 4 sprays in each nostril in a day.

                          Once your allergy symptoms get better, your prescriber will typically lower the dose to the smallest amount needed to keep your symptoms at bay. Some people might only need 1 spray in each nostril per day as a maintenance dose.

                          interactions

                          Interactions between Flunisolide and other drugs

                          Flunisolide may interact with certain medications or supplements. Always let your doctor and pharmacist know about any other medications or supplements (including prescribed and over-the-counter medications, vitamins, and dietary or herbal supplements) that you are currently taking. The list below does not include all possible drug interactions with Flunisolide. Please note that only the generic name of each medication is listed below.

                          Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
