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.
Viagra typically begins working within 30-60 minutes of taking it, with effects lasting up to 4-6 hours. The medication works by increasing blood flow to the penis when you're sexually aroused, but it still requires sexual stimulation to be effective. If you're finding that Viagra isn't working as well as it used to, several factors could be influencing its effectiveness.
One of the most common reasons Viagra may seem less effective is poor timing. Taking the medication with a large or fatty meal can significantly delay its onset of action. Alcohol can also interfere with effectiveness, as it reduces blood flow and can make it harder to achieve an erection even with medication. For best results, take Viagra on an empty stomach or after a light meal, and limit alcohol consumption.
Your health status may have changed since you first started taking Viagra, which could affect how well it works. Conditions such as diabetes, heart disease, or high blood pressure can worsen over time and impact erectile function. Additionally, new medications you've started taking may interact with Viagra or affect your ability to achieve an erection. It's important to keep your prescriber informed about any changes to your health or other medications.
Stress, anxiety, depression, or relationship problems can significantly impact the effectiveness of ED medications. If you're worried about whether Viagra will work, this anxiety itself can interfere with the medication's effectiveness. Performance anxiety can create a cycle where concern about erectile function makes the problem worse, even when taking medication.
Your current dosage may no longer be optimal for your needs. If you're taking 25mg or 50mg, your doctor might consider increasing to a higher strength. Conversely, if you're experiencing side effects, a lower dose combined with lifestyle changes might be more appropriate. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, with both containing the same active ingredient.
If Viagra has stopped working effectively, it's important to speak with a healthcare provider rather than simply increasing your dose. They can review your current health status, medications, and lifestyle factors to identify potential causes. Sometimes switching from Viagra to generic sildenafil (or vice versa) can help, as different formulations may work better for some individuals. Your prescriber might also consider alternative ED treatments if sildenafil-based medications are no longer suitable.
Regular exercise, maintaining a healthy weight, quitting smoking, and managing stress can all improve the effectiveness of ED medications. These lifestyle changes can enhance blood flow and overall sexual health, potentially making your current Viagra dosage more effective. Good sleep patterns and open communication with your partner can also contribute to better treatment outcomes.
