The main difference is duration. While Viagra (Sildenafil) lasts for about 4 hours, Cialis (Tadalafil) remains active in your system for up to 36 hours. This has earned it the nickname "the weekend pill," as it allows for greater spontaneity without needing to time your dose exactly right before intimacy.

No, and this is a common myth. The medication remains active in your system for 36 hours, meaning you can achieve an erection easily when stimulated during that window. You will not experience a continuous erection; the medication simply supports your body's natural response when you are aroused.

The recommended starting dose of Cialis is usually 10 mg, taken before anticipated sexual activity. However, your healthcare provider may adjust the dosage based on your individual response.

Cialis is generally safe for long-term use when taken as prescribed by a healthcare provider. However, regular follow-up appointments are recommended to monitor its effectiveness and assess any potential side effects.

Cialis can be taken with or without food. However, consuming excessive amounts of alcohol while taking Tadalafil may increase the risk of side effects and should be avoided.
