Doxazosin No Prescription
Doxazosin is prescribed for treatment and management of Hypertension and urinary obstruction symptoms of BPH.
Doxazosin is prescribed in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH), which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. Doxazosin (Doxazosin) is also used alone or in combination with other prescription to treat high blood pressure. Doxazosin is in a class of prescription called alpha-blockers. It relieves the symptoms of BPH by relaxing the muscles of the bladder and prostate. It lowers blood pressure by relaxing the blood vessels so that blood can flow more easily through the body.
A selective alpha-1-adrenergic blocker that lowers serum cholesterol. It is also effective in the treatment of hypertension.
Doxazosin mesylate is contraindicated in patients with a known sensitivity to quinazolines (e.g., prazosin, terazosin) or any of the inert ingredients.
Doxazosin Without a Prescription
Doxazosin comes as a tablet and an extended-release tablet to take by mouth. The doxazosin tablet is usually taken with or without food once a day in the morning or in the evening. The doxazosin extended-release tablet is usually taken once a day with breakfast. To help you remember to take doxazosin, take it around the same time every day.
Swallow the extended-release tablets whole; do not split, chew, or crush them.
Your doctor will start you on a low dose of doxazosin and gradually increase your dose, not more than once every 1 to 2 weeks. If you stop taking doxazosin for a few days or longer, call your doctor. Your doctor will have to start you again on the lowest dose of doxazosin and gradually increase your dose.
Doxazosin controls high blood pressure and the symptoms of BPH but does not cure them. It may take a few weeks before you feel the full benefit of doxazosin.
Doxazosin is an alpha-adrenergic blocking agent used to treat hypertension and benign prostatic hyperplasia. Accordingly, Doxazosin is a selective inhibitor of the alpha1 subtype of alpha adrenergic receptors. In the human prostate, Doxazosin antagonizes phenylephrine (alpha1 agonist)-induced contractions, in vitro, and binds with high affinity to the alpha1c adrenoceptor, which is thought to be the predominant functional type in the prostate. Studies in normal human subjects have shown that Doxazosin competitively antagonized the pressor effects of phenylephrine (an alpha1 agonist) and the systolic pressor effect of norepinephrine. The antihypertensive effect of Doxazosin results from a decrease in systemic vascular resistance and the parent compound Doxazosin is primarily responsible for the antihypertensive activity.
