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.
Cialis works by enhancing the effects of one of the chemicals the body normally releases into the penis during sexual arousal. This allows an increase of blood flow into the penis. An erection is the result of an increase in blood flow into certain internal areas of the penis.
Cialis provides penile hardness (the ability to obtain an erection) over a longer period than Viagra because it lasts up to 18 hours, while Viagra only lasts for about 4 to 6.
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.
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.
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.
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.
Peak plasma concentrations of Cialis are reached within 30 minutes to six hours (average time two hours) of a dose. Effects of 'as needed' Cialis last for up to 36 hours. The recommended starting dose for once-daily Cialis for ED is 2.5mg; once daily Cialis for BPH, 5mg; and 'as needed' Cialis, 10mg.
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 most common reasons why Cialis may not have worked are incorrect use or inadequate trial. It is important to understand that Cialis may not work after the first dose. It is advisable to try at least 8-10 doses before getting concerned about whether or not Cialis is working.
Using them incorrectly — having the wrong dosage or not following instructions — can cause Cialis not to work. Cialis might also fail if your ED is related to psychological issues — performance anxiety, intimacy issues, low self-confidence and depression can all affect your erections.
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.
Speak with your healthcare provider about a different dose
If Viagra isn't working for you, you might need a higher dose. But don't experiment on your own: Always speak with a healthcare provider about dosage changes and never take more than one dose of Viagra in any 24 hour period.
"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.
When taken correctly, Cialis should begin to work within 30-60 minutes. The effects of one Cialis tablet can last up to 36 hours; however during this period you will only achieve an erection if you become sexually aroused.
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.
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.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained. These medications may be combined with various creams aimed at reducing sensitivity.
You need a prescription from a doctor to buy tadalafil. You can buy it from a store-based pharmacy or reputable online pharmacy with a prescription.
Cialis works by relaxing smooth muscle cells in blood vessels, which widens them and increases blood flow.
Do not break or split a Cialis tablet. Swallow it whole. Take the medicine at the same time each day, with or without food.
