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.

What is Doxazosin Mesylate?

Doxazosin Mesylate, an alpha-adrenergic blocker, is the active ingredient that makes up the brand-name medication Cardura XL. It comes in the form of an oral tablet in 2 strengths; 4 and 8 mg. After being administered, Doxazosin Mesylate is metabolized by the liver and remains in the system for up to 5 days. The active ingredient, Doxazosin Mesylate, has been used in medicine since 1988, over 30 years ago. We carry the brand-name product, as well as the generic alternative, at My Drug Center; the brand-name product can be purchased in 4 and 8 mg while the generic is available in 4mg.

What is Doxazosin Mesylate used for?

Doxazosin Mesylate, in the form of Cardura XL, is used to help alleviate the symptoms of an enlarged prostate in male adults. An enlarged prostate, also known as benign prostatic hyperplasia (BPH) is a common condition that affects approximately one third (1/3) of men above the age 50; at the age of 85, about 90% of men may have an enlarged prostate. The prostate is located between the bladder and the penis and is about the size of a walnut; when a man has BPH, the prostate may now be the size of a lemon. This change in size can obstruct urination and cause irritating symptoms. These symptoms may include trouble starting to urinate, having to strain or push in order to urinate, and having to stop and restart several times. Additionally, the stream may be weak and urine may dribble out at the end. Please note; this medication is not used for hypertension, unlike the regular release form of this medication (Cardura); do not use this medication for anything other than what it has been prescribed for.
