zanamivir inhaler - oral, Relenza (cont.)
HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist and learn all usage instructions before you start using zanamivir. If you have any questions, consult your doctor or pharmacist.For flu treatment: inhale the medication through the mouth, generally 2 inhalations twice daily (about 12 hours apart) for 5 days or as directed by your doctor. When possible, take two doses (2 inhalations each) on the first day of treatment, waiting at least 2 hours between doses.For flu prevention: inhale the medication through the mouth, generally 2 inhalations once daily for 28 days or as directed.Remove the cover on the disk inhaler. Before use, check the mouthpiece to be sure it is clean and free of particles. Load the medication disk into the disk inhaler. Puncture one medication blister. Keep disk inhaler level so that the medication will not spill. Breathe out through the mouth, put the mouthpiece into your mouth, and breathe in deeply. Hold your breath for a few seconds so that the medication will stay in your lungs. If you have been directed to inhale a second time, advance to the next medication blister and repeat the process. Once you have taken the number of inhalations prescribed, replace the cover of the disk inhaler.Do not mix this powder medication with any liquids, including nebulizer liquids.If a child is using this medication, a parent or other responsible adult should supervise the child to make sure the zanamivir is taken properly.This medication works best when the amount of medicine in your body is kept at a constant level. Take the drug at evenly spaced intervals (e.g., every 12 hours when used for flu treatment).Continue to take this medication until the full prescribed amount is finished, even if symptoms improve. Stopping the medication too early may allow the virus to continue to grow, resulting in a relapse of the infection. If your condition persists or worsens, contact your doctor or pharmacist.When this drug is used for treating the flu, it is recommended that it be started within 48 hours of the beginning of flu symptoms.If you have breathing problems (asthma or chronic obstructive pulmonary disease-COPD) and are scheduled to use inhaled bronchodilators (e.g., albuterol) at the same time as zanamivir, use the asthma medication before using zanamivir. Ask your doctor or pharmacist for more details.
