Tadaga is a medication for erectile dysfunction treatment in men of all ages. It is based on Tadalafil, the same active substance which is used in Cialis. The drug is, in fact, identical to the brand-name medication but is simply manufactured by another company that markets it under its own trade name. Tadaga is cheaper than the brand medication but has the same safety level, effect, and duration of effect. Find out more about the drug from our med guide.
