3 Medications to Treat Erectile Dysfunction

Everything Men Need to Know About  Erectile Dysfunction Medication

Is erectile dysfunction making a healthy and fulfilling sex life impossible to achieve? You’re not alone in your struggle.

Erectile dysfunction is a disorder characterized by the inability to produce or maintain an erection This condition can occur at any age, although it is more common in older men over the age of 50. Due to the substantial amount of negative effects relating to both you and your partner, this issue is becoming more prevalent as more and more men seek diagnosis and treatment. 

What’s worse, ED can lead to a variety of adverse consequences including stress, relationship problems, low self-esteem, and the inability to conceive without medical intervention. Luckily, medical treatment can help to restore erectile function, giving you back a satisfying sex life and the confidence that comes with it. 

We offer three popular medications for the treatment of ED. They work by inhibiting a chemical in the body called phosphodiesterase type-5, allowing the blood vessels to relax. As a result, this increases blood flow to the penis which can encourage lasting erections. It is important to note, however, that the medications only work when sexually stimulated — and are not for increasing sex drive.
