How does Viagra work for ED?
Viagra is effective in treating ED, as confirmed by numerous clinical studies. These studies indicate that men using Viagra report a significant enhancement in their ability to attain and sustain an erection that is adequate for sexual activity. It’s crucial to note that Viagra does not induce an erection autonomously; sexual arousal is a prerequisite for the medication to take effect.
Note: The term “male” refers to individuals assigned male at birth within this content.
How long does it take for Viagra to work?
Viagra typically begins to take effect within 30 to 60 minutes post-ingestion. However, sexual stimulation is required for the drug to be effective. Its effects can last for up to 5 hours, facilitating multiple erections during this timeframe if conditions of arousal are met.
In rare instances, Viagra may cause a prolonged erection, known as priapism, lasting over four hours and necessitating immediate medical intervention to prevent permanent damage.
How can I enhance the efficacy of Viagra?
Taking Viagra on an empty stomach may enhance its effectiveness and speed of action. Heavy meals, particularly those high in fats, can delay the onset of effects, so it is advisable to avoid consuming such meals before taking the medication.
How does Viagra work?
Viagra is approved for treating ED in men by targeting the physiological mechanisms contributing to this condition. Upon sexual arousal, nitric oxide is released, promoting blood flow into the penis. Viagra assists this process by inhibiting an enzyme known as phosphodiesterase type 5 (PDE5). This inhibition raises cyclic GMP levels, promoting relaxation and dilation of blood vessels, thus enhancing blood flow during arousal.
Does Viagra boost sex drive?
No, Viagra does not enhance libido or sexual desire. While it assists in achieving an erection, it does not directly influence an individual’s interest in engaging in sexual activities.
When to consult a doctor?
Contact your healthcare provider if Viagra does not yield expected results after ingestion within the recommended timeframe, or if you experience persistent side effects that cause concern.
