When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.
High-fat meals can significantly delay how long Viagra takes to work. Foods rich in fats slow gastric emptying, meaning the medication takes longer to reach your bloodstream. For optimal results, take Viagra on an empty stomach or after a light meal. If you've had a heavy meal, particularly one high in fats, you may need to wait 2-3 hours before taking your dose, or expect a delayed onset of action.
While moderate alcohol consumption doesn't necessarily prevent Viagra from working, excessive drinking can interfere with both the medication's effectiveness and your ability to achieve an erection naturally. Alcohol is a depressant that affects blood flow and nervous system function. For best results, limit alcohol intake when planning to use ED medication. Both Viagra and sildenafil generic versions are affected equally by alcohol consumption.
Never take Viagra with nitrate medications such as GTN spray, isosorbide mononitrate, or glyceryl trinitrate tablets. This combination can cause a dangerous drop in blood pressure that may be life-threatening. Always inform your prescriber about all medications you're taking during your consultation. Other medications that may interact include certain blood pressure medications, alpha-blockers, and some antifungal drugs.
Viagra typically works within 30-60 minutes of taking it, but several factors can affect this timing. Taking the medication at the same time daily isn't necessary since it's used as needed. However, planning around meals, avoiding grapefruit juice (which can affect metabolism), and ensuring you're in a relaxed state can help optimise the medication's effectiveness. Remember that sexual stimulation is still required - Viagra doesn't cause automatic erections.
EverydayMeds offers both Viagra (branded) and sildenafil (generic) options at checkout. Both contain the same active ingredient and have identical effectiveness and safety profiles. The generic sildenafil provides the same benefits at a lower cost, while some patients prefer the branded option. The same precautions and timing considerations apply to both medications.
