Erectile Dysfunction Medicine: Where to Buy

Erectile Dysfunction

Erectile dysfunction (ED) is a condition that can cause difficulty in achieving or maintaining an erection, which can lead to decreased satisfaction with sexual activity.

Thankfully, there are several forms of erectile dysfunction medicine available today, ranging from lifestyle changes to prescription medication. This article provides an overview of how ED pills work and discuss their potential benefits and side effects.

Let’s get started.

An overview of erectile dysfunction

Erectile dysfunction (ED) is a condition that is defined by the inability to achieve or sustain an erection sufficient for satisfactory sexual activity. ED can have psychological effects that make it difficult for a man to develop and maintain an intimate relationship with his partner. 

The most common causes include stress, anxiety, depression, excessive alcohol consumption, smoking, diabetes, high blood pressure, low testosterone levels, and prostate cancer treatment.

How do erectile dysfunction pills work?

Here are five different ED pills and how they work:


Sildenafil works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down cGMP, a chemical that is needed to relax the blood vessels in the penis and allow for increased blood flow. By inhibiting PDE5, sildenafil helps to increase cGMP levels and improve blood flow to the penis, leading to an erection.


Tadalafil, sold under the brand name Cialis, works similarly to sildenafil by inhibiting PDE5. However, tadalafil has a longer half-life than sildenafil, which means it can be effective for up to 36 hours after taking a dose. This makes it a famous choice for those who want a longer window of opportunity for sexual activity.


Avanafil, sold under the brand name Stendra, works by inhibiting PDE5 and increasing cGMP levels, similar to sildenafil and tadalafil. However, avanafil has a faster onset of action than other ED pills, with some individuals experiencing results in as little as 15 minutes after taking a dose.


Udenafil, sold under the brand name Zydena, is a newer ED medication that works by blocking PDE5 and improving blood flow to the penis. It has a longer half-life than sildenafil and a faster onset of action than tadalafil, making it a popular choice for some individuals.


Vardenafil, sold under Levitra, also works by inhibiting PDE5 and increasing cGMP levels. It has a shorter half-life than tadalafil, but a faster onset of action than sildenafil, making it a good option for some individuals.

Common side effects of ED medication

Here are six common side effects of ED medication:


Headaches are among the common side effect of ED medication and can range from mild to severe. The cause of headaches is not fully understood, but it is related to blood flow and pressure changes.


Flushing is another common side effect of ED medication, characterized by redness or warmth in the face and neck. This occurs because the medication increases blood flow to the area.

Nasal congestion:

Nasal congestion is a side effect of ED medication. It can be caused by the medication’s effects on blood vessels in the nasal passages.

Digestive issues:

Some individuals may experience digestive issues, such as indigestion, nausea, or diarrhea, after taking ED medication. 

Vision changes:

Some individuals may experience vision changes, like blurred vision or sensitivity to light, after taking ED medication. 


In rare cases, ED medication can cause priapism, which is a painful and prolonged erection that lasts for more than four hours. This medical emergency requires immediate treatment to avoid permanent damage to the penis.


Erectile dysfunction medications can greatly help those suffering from the condition. While many options are available, it is important to discuss with your healthcare provider which type of medication is right for you and ensure you follow all instructions. With proper treatment, men can lead normal lives again and enjoy intimacy with their partners. 

Taking care of yourself is essential to maintaining good health, be sure to take steps toward addressing any problems associated with ED if they arise.


Why do I keep losing my erection?

It is normal to experience erection issues from time to time. There are several reasons why you are having difficulty maintaining an erection, including stress, anxiety, or health conditions such as diabetes or high blood pressure. It is important to discuss any concerns about erectile dysfunction with your doctor so that they can help you identify and treat the underlying cause. 

Is ED pills safe?

When taken as prescribed, erectile dysfunction (ED) medications are generally considered safe. However, like any medication, ED pills can have side effects and may interact with other medications you’re taking.

Can you get erectile dysfunction pills over-the-counter?

No, erectile dysfunction medications are prescription-only medications. To purchase ED pills, you must obtain a valid prescription from your medical professional.
