It contains a high dose of Sildenafil Citrate, the same active ingredient found in Viagra. This drug helps men achieve and maintain an erection during activity. Sildenafil works by relaxing the blood vessels in the penis and increasing blood flow during sexual stimulation. This allows for a firm, lasting erection. Fildena 200mg is one of the strongest available doses, typically used when lower doses are not effective. Fildena 200mg is taken orally, usually about 30 to 60 minutes before planned sexual activity. The effects can last for up to 4 to 6 hours.
