Relenza Overdose: An OverviewRelenza® (zanamivir) is a prescription drug used to both treat and prevent the flu (influenza). Although very little is known about what to expect from a Relenza overdose, it is reasonable to assume that the effects will vary, depending on a number of factors, such as the Relenza dosage and whether it was taken with any other medicines, alcohol, food, or street drugs.
If you happen to overdose on Relenza, seek immediate medical attention.
Effects of a Relenza OverdoseThere have been no reported cases of Relenza overdose. This is probably due to many factors, including the way the drug is packaged. It is unlikely that a small child could figure out how to work the inhaler or could accidentally ingest the Relenza powder, which is contained within blisters in a foil disk.
It is reasonable to expect that an overdose could cause any of the usual Relenza side effects. In particular, difficulty breathing could be a concern.
Treatment for a Relenza OverdoseIt is also not known how to treat a Relenza overdose. As a result, treatment will focus on supportive care, which consists of treating any of the symptoms that occur as a result of the overdose. For instance, if a Relenza overdose caused breathing problems, then medications may be given to help open up the airways.
It is important that you seek prompt medical attention if you believe that you may have overdosed on Relenza.
