Cialis (Tadalafil 20mg)

Method of Use



It is recommended that Cialis is taken orally between 30 minutes and 12 hours prior to sexual activity. Its effect will start within 30 minutes and will last for up to 48 hours. Cialis can be taken daily at approximately the same time, with or without food, and as directed by your doctor. However, please consult your doctor prior to consuming grapefruit or grapefruit juice whilst using Cialis. Should you miss a regular dose but still wish to engage in sexual activity, take Cialis as soon as you remember and then continue as directed.

A phosphodiesterase Type-5 inhibitor, Cialis boosts the blood flow in to the penis, helping to achieve and maintain an erection during sexual intercourse. However, sexual stimulation is required as an erection will not occur just by taking Cialis. Compared to Viagra and Levitra, Cialis’s effect lasts up to 48 hours, with fewer side effects and can be used daily, so you can be prepared for sexual activity at any time. Cialis is available in four dosage levels (40mg, 20mg, 10mg and 5mg), and 66% of users prefer Cialis to Viagra.
