|Drug Class: What is Cardura an why is it prescribed?|
Cardura is an antihypertensive (treatment of high blood pressure). Cardura lowers, but does not cure, high blood pressure.
Cardura is effective when used alone or in combination with other blood pressure medications, such as diuretics, beta-blocking medications, calcium channel blockers or ACE inhibitors. Cardura works by relaxing your blood vessels.
Cardura is used in the treatment of benign prostatic hyperplasia, a condition in which the prostate gland grows larger, pressing on the urethra and threatening to block the flow of urine from the bladder.
Cardura relieves symptoms such as a weak stream, dribbling, incomplete emptying of the bladder, frequent urination, and burning during urination.
|Drug Mechanism: How does Cardura work?|
Cardura contains the active ingredient doxazosin, which is a type of medicine called an alpha-blocker. Cardura works by blocking alpha receptors in certain areas of the body.
Alpha-receptors are found on the muscle in the walls of blood vessels. When Cardura blocks these receptors it causes the muscle in the blood vessel to relax and the blood vessel to widen. This lets the blood pass more easily through the blood vessels and hence reduces the pressure in the blood vessels. Cardura can therefore be used to treat high blood pressure.
Alpha-receptors are also found on the muscle in the prostate gland. This gland is found only in men and lies at the top of the tube connecting the bladder to the outside (urethra). The prostate gland often enlarges with advancing age (benign prostatic hyperplasia), pressing on the urethra and obstructing the flow of urine from the bladder. This can cause various urinary symptoms such as difficulty passing urine. By blocking the alpha-receptors, Cardura causes the muscle in the prostate gland to relax. This allows urine to flow freely past the prostate and relieves the urinary symptoms of this condition.
|Dosage: How should you take Cardura|
|Take Cardura tablets by mouth. Swallow the tablets with a drink of water. Take your doses at regular intervals even if you feel better.
Cardura can be taken with or without food.
Cardura should be taken exactly as prescribed, even if your symptoms have disappeared. Try not to miss any doses. If Cardura is not taken regularly, your condition may worsen.
Your doctor will adjust the dose of Cardura to fit your needs. The usual starting dose is 1 milligram taken once a day. To minimize the potential for dizziness or fainting associated with Cardura, which may occur between 2 and 6 hours after a dose, your doctor will monitor your blood pressure during this period and afterwards.
After the effects of the starting dose are measured, your doctor may increase the daily dose to 2 milligrams and then, if necessary, to 4 milligrams, 8 milligrams, or, in people with high blood pressure only, up to 16 milligrams. As the dose increases, the potential for side effects such as dizziness, vertigo, light-headedness, and fainting also increases.
The safety and effectiveness of Cardura in children have not been established. If you miss a Cardura dose
If you miss a dose of Cardura, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses of Cardura.
If you miss several doses of Cardura, call your doctor to see at what dose you should start again.
Cardura taken in excess can have serious consequences. Although no specific information is available, low blood pressure is the most likely symptom of an overdose of Cardura.

Most Important Fact about Cardura
Cardura should be taken regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Cardura; and you must continue taking it even if you are feeling well. Cardura does not cure high blood pressure; it merely keeps it under control.
Cardura precautions if you are pregnant or breastfeeding
The safety of Cardura in pregnancy has not been established. Cardura should therefore be used with caution during pregnancy, and only if the benefits to the mother outweigh any risks to the fetus.
Cardura is present in breast milk. The effect on the infant is unknown. It is recommended not to use Cardura when breastfeeding or, alternatively, not to breastfeed when taking Cardura. Seek medical advice from your doctor.
Special warnings about Cardura
Cardura may cause fatigue and dizziness. You should take care when performing potentially hazardous activites, such as driving or operating machinery, until you know how Cardura affects you and are sure you can perform such activities safely.
There is insufficient information regarding the safety and efficacy of Cardura in children. Cardura is not recommended for children.
Cardura can occasionally cause your blood pressure to drop when you move from a lying down or sitting position to sitting or standing, especially when you first start taking Cardura. This may make you feel dizzy or unsteady. To avoid this try getting up slowly. If you do feel dizzy, sit or lie down until the symptoms pass.
