Questions fréquentes
Is Meloxicam better than Chlorthalidone? ▾

Can Meloxicam and Chlorthalidone 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.
