Doxacard 4 mg Tablet

Doxacard 4 mg Tablet is an oral tablet containing 4 mg of doxazosin in each tablet. It belongs to the alpha-1 blocker class and is used to help lower blood pressure and, in some patients, to improve urinary symptoms caused by an enlarged prostate. This Doxacard 4 mg Tablet is the higher-strength tablet in the Doxacard line, so it is usually chosen only after a doctor has assessed how you respond to lower strengths. Each pack contains Doxacard 4 mg tablets supplied by Cipla, India, in a strip/box of 10 packs.

How it works: Doxazosin in Doxacard 4 mg Tablet relaxes and widens certain blood vessels, which helps blood flow more easily and can lower blood pressure. It also relaxes smooth muscle in the prostate and bladder neck, which can make urination easier in men with an enlarged prostate.

Compared with Doxacard 1 mg Tablet and Doxacard 2 mg Tablet, the Doxacard 4 mg Tablet delivers a larger dose in each tablet, so it is not the usual starting strength. Doctors may choose Doxacard 4 mg Tablet when a lower dose has been tolerated but more effect is needed, or when a patient’s treatment plan calls for this strength. Because it can lower blood pressure more strongly, the 4 mg tablet may be more likely to cause dizziness or lightheadedness, especially after the first doses or after a dose increase.

• High blood pressure
• Benign prostatic hyperplasia (BPH) symptom relief
• Urinary hesitancy or weak stream related to enlarged prostate
• Blood pressure control when a lower dose is no longer enough

• Swallow Doxacard 4 mg Tablet whole with water; do not crush, chew, or split it unless your doctor or pharmacist tells you to.
• Take it exactly as prescribed, and try to take it at the same time each day.
• Your doctor may prefer bedtime dosing, especially when starting or increasing the dose, to reduce dizziness from a sudden drop in blood pressure.
• You may take it with or without food unless your prescriber gives different instructions.
• Stand up slowly from sitting or lying down, especially after taking the first doses of Doxacard 4 mg Tablet.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up.

Each Doxacard 4 mg Tablet provides 4 mg of doxazosin per tablet, so this is a moderate-to-higher tablet strength rather than a starting dose for many patients. It is usually taken once daily, but your doctor may adjust the schedule based on your response, side effects, blood pressure, and whether it is being used for BPH. Do not take more than the amount your doctor prescribes; the maximum daily dose depends on your condition and individual treatment plan.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Doxazosin may include:

• Doxacard 4 mg Tablet can cause a first-dose blood pressure drop, so the 4 mg strength should only be used under medical supervision.

• Inform all healthcare providers that you take doxazosin before surgery or procedures, including eye surgery.
• Use extra caution if you also take medicines for erectile dysfunction or other blood pressure medicines, because the blood pressure-lowering effect may be stronger.
