Fildena Double 200 mg is one of the strongest sildenafil-based medications used to treat erectile dysfunction (ED). Fildena Double 200 mg should be taken 30 to 60 minutes before sexual activity, with or without food, and never more than once per day. Avoid alcohol and fatty meals, as they can reduce the drug's effectiveness or increase side effects. Never combine it with nitrate medications or other ED drugs. Fildena Double 200 mg may be effective, but it's not for everyone. A consultation with a healthcare provider is the best way to determine if it's the right and safest choice for your specific needs.
