Patients receiving zanamivir, commonly known as Relenza, may experience several side effects. Among the more frequently reported are headaches, throat and tonsil discomfort, and nasal symptoms.
Common Side Effects of Zanamivir (Relenza)
When undergoing treatment with zanamivir, marketed as Relenza, patients might encounter various side effects. These are generally mild to moderate and are often reported at similar rates in both the treated and placebo groups in clinical trials.
Here are some of the more commonly reported adverse events associated with zanamivir use:
| Adverse Event | Percentage in Zanamivir Group |
|---|---|
| Headaches | 24% |
| Throat and tonsil discomfort and pain | 19% |
| Nasal signs and symptoms | 12% |
It's important to note that while these percentages represent the incidence in the zanamivir group during studies, some of these effects, like headaches, were also common in individuals receiving a placebo, indicating they might not always be directly attributable solely to the medication.
