Cardura 4 Mg Tablets

Cardura 4 Mg Tablets

Description:

Cardura 4 mg tablets are a prescription antihypertensive medicine containing doxazosin, an alpha-1 adrenergic receptor blocker (alpha-1 blocker). They are used primarily to treat high blood pressure (hypertension) and symptoms of benign prostatic hyperplasia (BPH) in adult men by relaxing blood vessels and smooth muscles in the prostate and bladder neck. By reducing peripheral vascular resistance and improving urinary flow, Cardura 4 mg helps control blood pressure and relieve lower urinary tract symptoms associated with enlarged prostate. Use only under medical supervision.

Indications:

• Treatment of essential hypertension in adults, as monotherapy or in combination with other antihypertensive agents.
• Management of benign prostatic hyperplasia (BPH) in adult men, to improve urinary flow and reduce symptoms such as weak stream, hesitancy, incomplete bladder emptying, and nocturia.
• Reduction of total peripheral vascular resistance and improvement of blood pressure control in patients at risk of cardiovascular complications related to hypertension.

Active Ingredients / Key Components:

• Doxazosin mesylate – 4 mg per tablet (equivalent to 4 mg doxazosin).
• Excipients: Full list of inactive ingredients (e.g., fillers, binders, colorants) is not available in the provided information; please refer to the package leaflet for complete excipient details.

Dosage & Administration / How to Use:

• Use exactly as prescribed by your physician. Do not change your dose or stop treatment without medical advice.
• Hypertension (adults): Therapy is usually started with a lower dose (e.g., 1 mg once daily) to reduce the risk of postural hypotension, then gradually increased based on response. The 4 mg strength is typically used as a maintenance dose once daily, with the exact dose individualized by the doctor. Specific dosing regimen must be confirmed by the prescribing physician.
• Benign prostatic hyperplasia (BPH) in adult men: Treatment is usually initiated at a lower dose and titrated up. Cardura 4 mg may be used as a maintenance dose once daily as directed by the physician.
• Administration: Swallow the tablet whole with a glass of water. Do not crush or chew.
• Timing: Usually taken once daily, at the same time each day. It may be taken with or without food, but follow your doctor’s instructions.
• First-dose and dose increase precautions: To minimize the risk of dizziness or fainting, your doctor may advise taking the first dose and dose increases at bedtime. Stand up slowly from sitting or lying positions.
• If you miss a dose: Take it as soon as you remember unless it is almost time for your next dose. Do not double the dose to make up for a missed one.
• Do not use in children or adolescents unless specifically prescribed, as safety and efficacy in pediatric patients are not well established.

Clinical Benefits:

• Helps lower high blood pressure by selectively blocking alpha-1 receptors, leading to dilation of arteries and veins and reduced total peripheral resistance.
• Improves urinary flow and reduces symptoms of benign prostatic hyperplasia by relaxing smooth muscle in the prostate, bladder neck, and urethra.
• May contribute to better cardiovascular risk management by improving blood pressure control when used as part of a comprehensive treatment plan.
• Can be used alone or in combination with other antihypertensive medications, allowing flexible treatment strategies tailored to individual patient needs.

Warnings & Contraindications:

• Contraindicated in patients with known hypersensitivity to doxazosin, other quinazoline derivatives, or any component of the formulation.
• Use with caution in patients with a history of orthostatic hypotension, severe heart disease, liver impairment, or those on other blood pressure–lowering medications.
• May cause a marked drop in blood pressure, especially after the first dose or dose increases (first-dose effect). This can lead to dizziness, fainting, or falls. Stand up slowly and avoid sudden position changes.
• Use with caution in patients with existing prostate cancer; evaluation to exclude malignancy is recommended before starting treatment for BPH.
• May affect the ability to drive or operate machinery, particularly at the start of therapy or after dose adjustments, due to dizziness or fatigue.
• Inform your doctor about all other medications you are taking, especially other antihypertensives, phosphodiesterase-5 inhibitors for erectile dysfunction (such as sildenafil, tadalafil), and any drugs that may lower blood pressure, as additive effects may occur.
• Consult your doctor before use if pregnant, planning pregnancy, or breastfeeding. Doxazosin should only be used in pregnancy or lactation if the potential benefit justifies the potential risk, as determined by the physician.
• Not intended to diagnose, treat, cure, or prevent any disease without appropriate medical supervision and prescription.
• Keep out of reach of children.

Side Effects:

• Common side effects may include dizziness, headache, drowsiness, fatigue, weakness, palpitations, nausea, and edema (swelling of ankles or feet).
• Postural (orthostatic) hypotension, lightheadedness, or fainting can occur, especially after the first dose, dose increases, or when standing up quickly.
• Less common side effects may include dry mouth, nasal congestion, gastrointestinal discomfort, blurred vision, or skin rash.
• Serious but rare side effects can include severe hypotension, chest pain, shortness of breath, allergic reactions (swelling of face, lips, tongue, or throat, difficulty breathing), or priapism (prolonged painful erection). Seek immediate medical attention if these occur.
• If you experience persistent or bothersome side effects, or any unusual symptoms, contact your doctor or pharmacist promptly.
