Fildena Double 200 mg is a medication that contains sildenafil, which is commonly used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. Typically, sildenafil-based medications like Fildena Double 200 mg are taken on an as-needed basis rather than on a regular schedule. You usually take it about 30 to 60 minutes before sexual activity. It’s not designed for daily use or long-term regular use in the same way that some other medications might be. However, if you have any specific questions about how to use it or how often you should take it, it's always best to consult with your healthcare provider. They can give you personalized advice based on your health needs and medical history.
