These tabs have a vasodilating effect, meaning that they open up the blood vessels so that enough blood reaches the penis for it to become erect as a response to arousal. They do not, however, cause an erection on their own. Moreover, they are an as needed medicine, so they can be taken at any point during the day or night, but no more than once every 24 hours. Talk to your local doctor for more info on how to properly use these Viagra or Cialis soft tabs (it is understood that both Sildenafil and Tadalafil should not be used at the same time).

Both Tadalafil and Sildenafil are PDE5 inhibitors, substances that are known to have negative interactions with such drugs as nitrates and alpha blockers. Other studied interactions include HIV protease inhibitors, and antifungal medications like ketoconazole and itraconazole. Do not forget to tell your doctor about all the medicines you have taken in the past and are taking now, so that all possible interactions may be anticipated.

Soft Tabs have the same side effects that other presentations of Cialis and Viagra drugs, both generic and branded, including but not limited to headache, dizziness, nausea, and other mild adverse effects. If, on the other hand, you were to experience more serious reactions, like an allergic reaction, or priapism, do not hesitate to search for urgent medical care. All in all, many patients do not report any side effects at all with Soft Tabs, and those who do find them to be moderate and temporary for the most part.
