Cardura is a medication that belongs to a class of drugs known as alpha-adrenergic blockers. The generic name of Cardura is doxazosin, and it is available in both brand-name and generic forms. This medication is primarily prescribed to treat high blood pressure (hypertension) and symptoms of an enlarged prostate (benign prostatic hyperplasia).

Cardura works by relaxing the muscles in the blood vessels and prostate, which allows for easier blood flow and relieves the symptoms associated with hypertension and an enlarged prostate. It is classified as an alpha-1 antagonist and functions by blocking certain receptors in the body.


Cardura should not be taken by individuals who are allergic to doxazosin or any other ingredients present in the medication. It is essential to inform the healthcare provider about any known allergies or sensitivities before starting this medication.

Furthermore, Cardura is contraindicated in patients with a history of orthostatic hypotension, a condition where the blood pressure drops significantly upon standing. It is also not recommended for individuals with liver disease or severe kidney disease, as doxazosin is primarily metabolized and excreted through the liver and kidneys.

Potential Side Effects

As with any medication, Cardura can cause certain side effects. However, not everyone who takes this medication will experience these side effects, and their severity may vary from person to person.

Common side effects of Cardura include dizziness, lightheadedness, headache, drowsiness, unusual tiredness, and swelling in the hands and feet. These side effects are usually mild and temporary. However, if they persist or worsen, it is important to inform your healthcare provider.

In rare cases, Cardura may cause more serious side effects, such as a prolonged and painful erection (priapism) or an allergic reaction. If you experience any of these serious side effects, seek immediate medical attention.

It is essential to note that this is not a complete list of all possible side effects. If you notice any other unusual symptoms while taking Cardura, contact your healthcare provider.


Cardura is available in tablet form and is typically taken once daily. It is important to follow the dosing instructions provided by your healthcare provider and take the medication at the same time each day.

If you miss a dose of Cardura, take it as soon as you remember. However, if it is close to the time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not take a double dose to make up for the missed one.

Overdosing on Cardura can lead to excessively low blood pressure, causing symptoms such as dizziness, fainting, or rapid heartbeat. In case of an overdose, seek immediate medical attention or contact a poison control center.

What to Watch Out For

It is crucial to be aware of potential drug interactions when taking Cardura. This medication may interact with other drugs, which can affect its effectiveness or increase the risk of side effects.

Cardura should not be taken concomitantly with other alpha-blocking medications, as this can lead to an increased risk of low blood pressure.

Additionally, certain medications like sildenafil (Viagra) or other phosphodiesterase inhibitors used for the treatment of erectile dysfunction can enhance the blood pressure-lowering effects of Cardura.

It is important to inform your healthcare provider about all the medications, including prescription, over-the-counter, and herbal supplements, that you are currently taking. They can help assess any potential interactions and adjust your treatment regimen accordingly.
