A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Cardura is a medication that belongs to a class of drugs called alpha-blockers. It is primarily used to treat high blood pressure (hypertension) and urinary symptoms associated with an enlarged prostate gland (benign prostatic hyperplasia or BPH). Cardura works by relaxing the muscles in the blood vessels and in the prostate, allowing for improved blood flow and the relief of urinary symptoms.
Before you buy Cardura or Cardura generic, it is important that you talk to your healthcare provider about its potential side effects and effectiveness.

What is Cardura, and what is it used for?
Cardura is a brand name for the medication doxazosin. It belongs to a class of drugs called alpha-blockers and is primarily prescribed to treat high blood pressure (hypertension) and benign prostatic hyperplasia (BPH), a condition where the prostate gland enlarges, causing urinary problems.
How does Cardura work to lower blood pressure?
Cardura works by relaxing the muscles in blood vessel walls, making it easier for blood to flow. This relaxation of blood vessels reduces resistance and ultimately lowers blood pressure.
Can Cardura cure high blood pressure or BPH?
No, Cardura does not cure high blood pressure or BPH. It helps manage the symptoms and complications associated with these conditions. To maintain its benefits, you need to continue taking the medication as prescribed by your healthcare provider.
What is the recommended dosage of Cardura?
The dosage of Cardura varies depending on the condition being treated. Typically, the starting dose for high blood pressure is 1 mg daily, while for BPH, it may start at 1 mg daily and increase gradually. Follow your doctor's instructions carefully on your recommended dosage.
How should I take Cardura?
Cardura is usually taken by mouth with or without food, as directed by your healthcare provider. It is essential to take it at the same time each day to maintain a consistent level of the medication in your body. Swallow the tablet whole and do not crush or chew it.
What are the potential side effects of Cardura?
Common side effects of Cardura may include dizziness, lightheadedness, headache, tiredness, and stomach upset.

Contact your healthcare provider if you experience severe or bothersome side effects.
Can I drink alcohol while taking Cardura?

Can I stop taking Cardura abruptly?
No, do not stop taking Cardura suddenly without consulting your healthcare provider. Abruptly discontinuing the medication can lead to an increase in blood pressure or worsening of BPH symptoms. Your doctor will provide guidance on how to gradually reduce the dose if necessary.
Is Cardura available as a generic medication?
