Sildenafil vs tadalafil

Sildenafil vs tadalafil: what is the difference?

Sildenafil and tadalafil are different prescription ED medications. Sildenafil is associated with Viagra, while tadalafil is associated with Cialis. The right option depends on your health, other medicines and the prescription a physician considers appropriate.

The direct answer

Sildenafil and tadalafil are both prescription ED medications, but they are not interchangeable. A physician considers safety, timing preferences, other medicines and health history before selecting a product and dose.

01

Sildenafil: generic Viagra

Sildenafil is generally prescribed for use according to a specific dosing plan. The prescribed strength and instructions must come from the physician and dispensing pharmacy.

02

Tadalafil: generic Cialis

Tadalafil may be prescribed using different schedules depending on the patient and indication. The physician determines whether it is appropriate and how it should be used.

03

Which medication should you request?

You may state a preference, but do not choose solely from advertising or another person’s experience. The physician’s decision must account for contraindications, interactions and your complete health information.

04

Help for erection difficulties

Getting and keeping an erection: how medication helps

Sildenafil and tadalafil help blood vessels relax, improving blood flow during sexual stimulation. That can make it easier to get and keep an erection firm enough for sex.

Losing your erection during sex?

ED can also mean getting an erection but not keeping it. Learn about losing firmness and when medication may be an option.

Difficulty keeping an erection

Erections feel less reliable?

An occasional difficulty does not always need medication. A recurring change is worth discussing, especially if it is affecting your sex life.

Occasional versus recurring ED

Sexual stimulation is still needed. These medicines do not increase desire and are not suitable for everyone; a prescription is required.
