RELENZA-Inhalant
Zanamivir is used to treat symptoms caused by the flu virus (influenza) if you have had symptoms for 2 days or less. It helps lessen symptoms (such as stuffy nose, cough, sore throat, fever/chills, headache, body aches, tiredness) and shortens the recovery time by about 1 to 2 days. Zanamivir may also be used to prevent the flu if you have been exposed to someone who already has the flu (such as a sick household member) or if there is a flu outbreak in the community. Talk to your doctor for more details. This medication works by stopping the flu virus from growing. It is not a substitute for the flu vaccine. If you have the flu, zanamivir does not reduce the risk of giving the flu to others.
Dizziness may occur. Also, because this medication is an inhaled powder, you may experience increased coughing after using it. If either of these effects persists or worsens, 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. This medication can cause breathing problems, which in rare cases can be fatal. If you experience trouble breathing such as wheezing or shortness of breath, stop using zanamivir and get medical help right away. Zanamivir is not recommended if you have lung/breathing problems. Discuss the risks and benefits with your doctor. However, if your doctor decides you should use zanamivir, have a quick-relief inhaled bronchodilator (such as albuterol inhaler) readily available. The flu itself or zanamivir may rarely cause serious mental/mood changes. This may be more likely in children. Tell your doctor right away of any signs of unusual behavior, including confusion, agitation, self-injury. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, 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.
