Erectile dysfunction is a common condition that affects millions of men, but ED is not a normal sign of aging. If you experience male sexual dysfunction, you should not hesitate to bring up concerns to your doctor. The earlier you get a handle on your ED symptoms, the quicker you will be back to a healthy and full life. Your doctor may prescribe several medications like Viagra, Cialis, or Levitra. Cheap tadalafil and sildenafil are available at discounted rates through online pharmacies like Mail My Meds. So, what’s the difference between these popular drugs? Read on to learn more. 1 

The Function of ED Drugs 

All of these drugs are approved for use by the Food and Drug Administration (FDA) and work in similar ways. Viagra, Cialis, and Levitra can help men achieve and maintain an erection through a chemical called phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme that affects blood flow and affects how cells signal in the body.

When a PDE5 inhibitor is present, it prevents PDE5 from working, relaxing the blood vessels and increasing blood flow. In the case of ED, these drugs increase blood flow to the penis and improve erectile dysfunction. Viagra, Cialis, and Levitra all include a PDE5 inhibitor, but they differ slightly in chemical makeup and the amount of time they need to be taken before a man wants to participate in sex. 2

Do These Drugs Increase Sex Drive?

Contrary to popular belief, ED drugs do not increase a man’s sex drive. Viagra, Cialis, and Levitra help men achieve erections only if sexual stimulation is present. These drugs do not make a man sexually aroused. If these drugs help a man with ED symptoms, their sexual confidence is likely to rise, which may be misconstrued as increased sex drive. You must note that these drugs may not work for everyone and may not work every time. 3 

Key Differences

These medications are quite similar, but there are a few factors that differentiate the drugs. The main difference between the drugs is the amount of time you have to take the drugs before participating in sexual activities. The lasting power of each drug also differs.

  • Viagra: Men should only take this drug when needed. It is recommended to take it 30 minutes to one hour before sex, and it typically lasts for three to five hours.
  • Cialis: This drug lasts longer than Viagra or Levitra, lasting up to 36 hours.
  • LevitraLevitra has been found to start working faster than Viagra but lasts for a similar time (three to five hours). 4 

Viagra and Levitra are usually taken as needed, whereas people may take Cialis daily. Cialis is available in low-dose versions, which is beneficial for some people because you can have sex anytime without the worry of ED symptoms. 5

Which ED Drug is Right for You? 

It depends. It would help if you considered several factors before you and your doctor decide on an erectile dysfunction drug. You may want to ponder the following questions before making a decision:

  • How often do you have sex?
  • How much alcohol do you drink?
  • How important is sexual spontaneity to you?
  • Do you take any other medications? 

It is essential to be transparent with your doctor about your health conditions and the medications you take. If you are taking high blood pressure drugs, antifungal drugs, HIV drugs, or nitrate medications for heart conditions, you may experience ED drug interactions. Your doctor may also ask if you have a history of heart problems, stroke, liver or kidney problems, stomach ulcers, blood cell problems, or an abnormal penis shape. 5
