The biggest difference between Viagra and Cialis is the amount of time their effects last. Viagra remains effective for 4 to 6 hours, which offers ample opportunity to have sex on multiple occasions if you wish. However Cialis typically allows you to achieve erections for up to 36 hours after taking a tablet.
So to answer the above question, no, Viagra would not necessarily give a stronger erection than Cialis, and vice versa. However, Cialis will last longer and can help achieve one or more erections for up to 36 hours. This is considerably longer than Viagra, which is typically effective for 4-6 hours.
20mg is the maximum dose of Cialis and 100mg is the maximum dose of Viagra, meaning your healthcare provider may suggest that you use 100mg of Viagra if you're prescribed Cialis and want to change medications. Ultimately, Cialis and Viagra are different medications that treat the same condition.
It relaxes the smooth muscles and arteries inside the penis. At the same time, it increases blood flow to the penis. When aroused, this combination of relaxation and increased blood flow allows the penis to fill with blood, which results in an erection. Good to know: Cialis only works if you're sexually aroused.

Three of the most popular erectile dysfunction drugs on the market are sildenafil (active ingredient in Viagra®, generic Viagra), vardenafil (Levitra®) and tadalafil (Cialis). These are all first-generation treatments for ED that were introduced in the 1990s and early 2000s.
Recent studies have found that exercise, especially moderate to vigorous aerobic activity, can improve erectile dysfunction. Even less strenuous, regular exercise might reduce the risk of erectile dysfunction. Increasing your level of activity might also further reduce your risk.
A penile erection can normally last anywhere from a few minutes to about half an hour. On average, men have five erections a night while they're sleeping, each lasting about 25 to 35 minutes (Youn, 2017).
Viagra does not stimulate you sexually, it can only help you get an erection once you're already aroused. Because Viagra only helps you to get an erection by improving blood flow to the penis, it doesn't force you to get an erection, so it won't work unless you're sexually stimulated.
Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues.
The usual dose is 40mg – two 20mg tablets, taken once a day. If you have kidney or liver problems your doctor might decrease the starting dose to 10mg or 20mg.

You should take Cialis at least 2 hours before you plan to have sex. The effects may last for up to 36 hours after you take it.
The most common side effects with Cialis are: headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. These side effects usually go away after a few hours. Men who get back pain and muscle aches usually get it 12 to 24 hours after taking Cialis.
Taking Cialis and Viagra together doesn't offer a combined beneficial effect on ED. Although Cialis and Viagra aren't known to interact dangerously (they are both the same type of medication), you will be increasing the overall risk of side effects.
Because 100mg is the highest dose available, you should never 'double up' on tablets or take more than one in 24 hours. Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment.
Penile implant. A penile implant involves a 30- to 45-minute surgical procedure that places a water-based device into the erection chambers of the penis, which enables you to reliably control exactly when and how long an erection lasts. Dr. Starke says this is the closest option to a cure that exists for ED.
Patients who are taking nitrates, alpha-blockers, and other classes of drugs are not eligible to take certain erectile dysfunction medications, including Viagra, Cialis, and others. Mixing these medications can actually lead to a life-threatening or even fatally low blood pressure level.
In this case, Cialis may keep working for up to 36 hours in helping you have and maintain erections during that time. However, if you take Cialis each day for either benign prostatic hyperplasia (BPH) or ED, you'll always have medication in your system. Therefore, it will continue to work throughout the day.
"Our study shows Cialis works very well for these men with problems ejaculating." Dr. Paduch says up to 18 percent of men have a normal erection but don't ejaculate, or take a long time to do so. He adds that while the issue may be more prevalent in the elderly, it affects men of all ages.
Viagra and Cialis May Cut Risk of Early Death From Heart Disease by 25 Percent. A large new study shows that men who take erectile dysfunction medication are less likely to experience heart failure, stroke, and heart attack.
