Viagra, containing sildenafil citrate, is a well-known medication for treating erectile dysfunction (ED). Each pack of Viagra 100mg Film-Coated Tablets contains four tablets designed to help men achieve and maintain erections sufficient for sexual activity. With its active ingredient, sildenafil, this medication works by increasing blood flow to the penis during sexual stimulation, aiding in the erection process. Hence, you can maintain bigger, harder, and stronger erections to achieve all benefits of a healthy sex life. It is advisable to take one tablet orally approximately 30-60 minutes before planned sexual activity, allowing time for the medication to take effect. The effects typically last up to four hours, but individual responses may vary.
