Relenza Side Effects
Although most people do not experience any problems while taking Relenza, side effects are possible. During clinical trials, some of the most common side effects included fever, sinus infections, and dizziness. Although side effects of Relenza are typically minor and easily treated, some may require immediate medical attention, such as difficulty breathing, seizures, and allergic reactions.
Relenza Side Effects: An IntroductionAs with any medicine, Relenza® (zanamivir) can cause side effects. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Relenza. Your healthcare provider can discuss a more complete list of Relenza side effects with you.)
Common Relenza Side EffectsRelenza has been thoroughly studied in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and then compared to the side effects that occur in another group of people not taking the medicine. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine. If a potential "side effect" occurs more frequently in people not taking the medication, it is not a true side effect.
In these studies, the most common Relenza side effects included:
- Sinus infections
- Ear, nose, or throat infections
- Joint pain or other joint problems.
Many other "side effects" occurred during these clinical studies, but these problems occurred just as often (or more often) in the people who were not taking Relenza.
