When Cialis is taken for daily use, the recommended initial dosage is 2.5mg once daily, or 5mg for people who also have BPH. Timing of the daily dosage does not matter in people using it solely for ED; however, those with BPH are advised to take it at the same time each day. Do not take more than one dose a day but your doctor may consider an increase in dosage from 2.5 to 5mg if ineffective. Side effects of Cialis include headache and indigestion. 1.
Cialis is the brand name for tadalafil and Viagra is the brand name for sildenafil. 1,2 Both belong to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors work only in the presence of sexual stimulation, as they rely on the natural release of nitric oxide (NO), a chemical only released during sexual arousal. NO in turn activates other substances to relax the smooth muscle inside the penis to allow the inflow of blood and an erection to occur. 1,2,3 PDE5 inhibitors enhance the effect of NO. 1,2.
