Fildena Super Active contains sildenafil citrate, the active ingredient found in medications like Viagra, and is used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, helping men achieve and maintain an erection during sexual activity. Sildenafil’s effects usually last around 4 to 6 hours, and taking another dose before 24 hours have passed could lead to an overdose or excessive levels of the drug in your system. Taking more than one dose per day could increase the risk of side effects such as headaches, dizziness, low blood pressure, and visual disturbances. If you’re unsure about the dosage or have concerns about how often you should take it, it’s best to follow up with your doctor for personalized advice.
