Why does he feel unwell after Polvertic?

Polvertic may cause side effects, mainly from the gastrointestinal tract, e.g. nausea and vomiting. To avoid these effects, it is best to take the medicine with a meal. Each drug poses a risk of side effects, but sometimes they disappear during treatment. It also happens that the positive effects of the drug are so large that some side effects can be accepted. If you feel unwell enough to stop treatment, tell your neurologist who will decide whether to change your treatment.
