Cardura XL is an extended release tablet made up of doxazosin mesylate. This medication is known as a beta blocker and comes in doses of 4mg and 8 mg. We carry both the brand name (Cardura XL) and its generic alternative, named after Cardura XLS ingredient (doxazosin mesylate)!
Cardura XL is very similar to Cardura but also has some important differences. Unlike Cardura, Cardura XL is not (and should not be) used to treat hypertension (high blood pressure). However, just like the original Cardura, it is used to treat BPH (benign prostatic hyperplasia) which is when a man’s prostate is enlarged. This can cause unwanted urination troubles where urination is hard to achieve or needing to urinate frequently or urgently (even while asleep).
Cardura XL works because the doxazosin mesylate acts on the prostate and bladder neck by relaxing the muscles. It does not shrink the prostate but relaxing the muscles allows relief from the symptoms.
