Questions fréquentes
Is Minoxidil better than Tadalafil? ▾
Minoxidil and Tadalafil are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Minoxidil and Tadalafil be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.
