The Buzz:

Erectile drugs increase the flow of into blood to the penis making it easier to get hard and stay hard. You may still need to stimulate yourself to make yourself erect.

A higher dose doesn’t mean better erections, but does increase the chance of an overdose and negative effects.

    • Avoid taking with nitrate medications, such as Poppers. Combining them can cause life-threatening hypotension or fatal drop in blood pressure.
    • Sildenafil and Vardenafil take 24 hours to leave the body, and Taladafil is still in effect up to 36 hours. Wait these lengths of time before taking more Erectile Drugs or Poppers.

    • Priapism: if you have an erection that lasts for more than 4 hours, get medical attention ASAP. Permanent damage and impotence can result in excessively prolonged erections.
    • Fake Erectile Drugs are available over the internet. Be careful to research into what you are getting.
