Filagra, also known as sildenafil, is commonly used to treat erectile dysfunction. Tremors are not typically listed as a common side effect of sildenafil. However, like any medication, individual reactions can vary, and some people may experience uncommon side effects. If you're experiencing tremors or any other concerning symptoms while taking Filagra, it's important to consult with your healthcare provider. They can evaluate your symptoms and determine the best course of action, which may include adjusting your medication or exploring other potential causes for the tremors.
