Precautions
Drug information provided by: Merative, Micromedex®
It is very important that your doctor check your or your child's progress after treatment. This is to make sure that the infection is cleared up completely, and to allow your doctor to check for any unwanted effects.
This medicine is not a substitute for an annual flu shot. It also will not keep you or your child from getting a bacterial infection that starts with flu-like symptoms.
Zanamivir may cause people with lung disease (e.g., chronic obstructive lung disease or asthma) to have shortness of breath, trouble breathing, or wheezing. If you have these symptoms after using this medicine, stop using this medicine and call your doctor right away.
Bronchospasm (wheezing) is a risk for patients with asthma or chronic respiratory disease. Always have a fast-acting inhaled bronchodilator available for your use.
This medicine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Stop using this medicine and call your doctor right away if you or your child have itching, hives, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.
Zanamivir may cause some people, especially children and teenagers, to be agitated, irritable, or display other abnormal behaviors, which may result in injury. If you, your child, or your caregiver notice any of these side effects, tell your doctor or your child's doctor right away.
Make sure your doctor knows if you or your child plan to get the live nasal flu vaccine (FluMist®) before you start using this medicine. You should not receive the vaccine within two weeks before or 48 hours after using this medicine.
If your or your child's symptoms do not improve after you or your child finish taking the medicine, or if they become worse, check with your doctor.
