Q: Are the symptoms such as tremors in the limbs, dull eyes, and slow movement after taking the medication side effects or an aggravation of the disease? Is it necessary to stop or change the medication if side effects occur? A: If there are no such symptoms before taking the medication, then it is more likely to be considered a side effect of the medication. This manifestation of side effects is called extrapyramidal syndrome (EPS). If the medication is still effective, it is not recommended to stop the medication and drugs such as Antan can be added to improve the side effects. If such side effects are still not relieved by taking drugs such as Antan, then consider reducing or stopping the drug or changing the drug. Of course, if the medication is not effective and EPS is obvious, consider stopping the medication and switching to another medication.
