• Purpose: Viagra 100mg (sildenafil) by Pfizer is used to treat erectile dysfunction (ED) by increasing blood flow during sexual stimulation.
• Lethal Interaction: Never take with nitrates (chest pain medication); doing so causes a life-threatening drop in blood pressure.
• Key Risks: Seek emergency care if an erection lasts over 4 hours (priapism). Avoid if you have severe heart conditions.
Viagra 100mg is used to treat erectile dysfunction (ED) in men.
It works by relaxing the blood vessels in the penis. When sexual stimulation occurs, this relaxation allows increased blood flow into the penis, helping to achieve and maintain an erection firm enough for sexual activity. • It is not an aphrodisiac: It will not increase sexual desire or arousal on its own. Sexual stimulation is required for the medication to start working.
• Timing: It is typically taken 30 minutes to 1 hour before planned sexual activity.
• Duration: The medication remains active in the body for about 4 hours, meaning it helps you get an erection during that window if you are sexually stimulated.
