What’s the difference between Viagra and Cialis? 

Cialis (using the active ingredient Tadalafil) and Viagra (using the active ingredient Sildenafil) are both medications that are used to treat erectile dysfunction (ED), however they differ in key aspects such as how long they last, how they should be taken and a breakdown of the main differences.

•  Cialis typically starts to work within 30 minutes of taking it and its active ingredient (tadalafil) stays active in the body for 36 hours after taking it.
• Viagra typically starts to work for an hour after taking it and it’s active ingredient (sildenafil) stays active in the body for 4 hours after taking it. 
• Neither of these drugs cause erections to last for the full time period, instead they allow spontaneous erections whenever sexually aroused, erections should last a normal amount of time to complete sexual activity. 
• Cialis and Viagra both have dosages of 10mg and 20mg that can be taken prior to planned sexual activity to treat erectile dysfunction.
• Cialis has a lower dose (2.5mg or 5mg) which can be taken every day of the week to allow spontaneous sexual activity whenever required. The higher doses of Cialis or any dose of Viagra should not be taken more than once a day or daily, they should be taken 2-3 time a week. 

Both medications have similar side effects common to all ED medications such as headaches, flushing of the hands and face, indigestion and nasal congestion.

•  Cialis is more likely to cause muscle pains or bache pains than Viagra
• Viagra is more likely to cause visual disturbances than Cialis 

These common and mild side effects should gradually disappear with continued use, however if you find that they persist, please speak to your healthcare provider.

Cialis is less affected by food and can be taken with or without food. It is minimally affected by high fat meals. Viagra’s effectiveness can be reduced if taken with or after a heavy or high-fat meal.

The price of each medication varies depending on the dosage and whether you are purchasing the generic forms, i.e: Sildenafil and Tadalafil, or the branded forms, i.e Viagra or Cialis, respectively.

Please see our website page at Meds For Less, for each branded drug and the respective pages for the generic forms to compare prices.
