Erectile Dysfunction Prescriptions: Comparing ED Medication Options

By: Noah W Chung | PharmD

Choosing the right erectile dysfunction medication can feel overwhelming for many people who are trying to understand how ED drugs differ in effectiveness, timing, side effects, and cost. With several trusted PDE 5 inhibitors available, men often look for clear comparisons that explain which medication fits their lifestyle. Since prescription costs continue to rise, affordability has also become a central part of the conversation. Platforms such as SaveHealth.com help people compare pharmacy prices and explore cost saving opportunities for various prescriptions.

The guide below breaks down the major ED medications so you can approach your treatment options with clarity and confidence.

How Erectile Dysfunction Medications Work

Nearly all prescription ED drugs fall into the category of PDE 5 inhibitors. These medications work by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain erections more consistently.

What PDE 5 inhibitors do

• Increase nitric oxide levels in the body which activates an enzyme guanylate cyclase to produce cGMP (cyclic guanosine monophosphate)

• cGMP triggers to help relax smooth muscle tissue in the penis

• Improve blood vessel dilation

• Support stronger and more sustained erections

• Require sexual arousal to be effective

• Do not influence libido

Understanding how these medications work makes it easier to select the best option based on timing, duration, or personal preference. Cost can also play an important role. Some men learn quickly that switching brands or exploring generics can reduce spend significantly. This is where SaveHealth.com is helpful because it allows people to compare pharmacy prices for ED medications.

Most Common ED Medications

The four major prescription ED drugs available today are sildenafil, tadalafil, vardenafil, and avanafil. Each offers a unique profile that suits different needs.

ED Medication Comparison Table

This type of comparison helps highlight how lifestyle habits influence the best ED medication choice. Some men prefer longer action so they do not have to plan ahead, while others prefer shorter acting tablets that can be taken only when needed. Cost differences also become more noticeable when comparing medications, which is where SaveHealth.com can help people view pharmacy prices side by side.

Effectiveness of Major Erectile Dysfunction Drugs

All four medications are considered effective for erectile dysfunction, but drug have distinguishing characteristics that influence user preference.

Sildenafil

Even though tadalafil can cost more than other medications, affordability tools make it easier to find competitive pricing.
