Can headaches occur when taking oseltamivir?

A headache side effect has been reported very commonly with oseltamivir in more than 1 in 10 people. The specificity of the pain has not been specified, it is possible that the severity and continuity is intensified by the course of the infection. Complete elimination of the drug and its metabolites from the body after stopping taking it is about 30h to 50h. After this time, side effects should not occur. If side effects prevent normal functioning and pose a health risk, report this to your doctor.
