Terazosin Tablets for Benign Prostatic Hyperplasia and Hypertension

What Terazosin Is and How It Works

Terazosin is an alpha-1 adrenergic blocker used for benign prostatic hyperplasia (BPH) and high blood pressure. It relaxes smooth muscle in the prostate and bladder neck, and it lowers vascular resistance. Tablets are taken once daily, usually at bedtime. Common strengths include terazosin 2 mg, 5 mg, and 10 mg. Terazosin is the generic of Hytrin®.

YouDrugstore is a licensed Canadian pharmacy based in Manitoba. Orders are processed under Canadian pharmacy standards, and prescriptions are reviewed by licensed pharmacists before dispensing. We offer brand and generic medicines at Canadian prices, and we also carry OTC health products.

We source through licensed, vetted partner pharmacies worldwide to keep a broad selection of authentic medicines available at affordable pricing.

Dosage and Usage

Terazosin dosing is individualized. A low first dose reduces the risk of dizziness or fainting. For BPH and hypertension, therapy often begins at 1 mg at bedtime, then increases in steps. Typical maintenance ranges are 2–10 mg once daily. Some patients need up to 20 mg daily, as directed by a prescriber.

If a dose is missed, the next scheduled dose is usually taken. After several days off therapy, the low starting dose is often used again, then retitrated. Stand up slowly, especially after the first dose and after increases. Avoid driving until individual response is known.

• Store tablets at 15–30°C in a dry place away from light.
• Keep in the original bottle when possible to protect from moisture.
• Bring your prescription label when you travel.
• Pack extra doses in your carry-on if you fly.
• If heat is expected, use an insulated pouch; do not freeze.
• Set reminders so you take your dose at the same time each night.

Benefits and Savings

In BPH, terazosin can reduce urinary hesitancy, weak stream, and nocturia. It works on dynamic obstruction by relaxing prostate and bladder neck muscle. In hypertension, it lowers blood pressure by dilating arteries and veins. Once-daily bedtime dosing supports adherence.

Buying from YouDrugstore can lower out-of-pocket costs. Many patients see 60–80% savings versus typical US retail prices for comparable products. Per-month costs may drop further with multi-month supplies. Reorder reminders can help you stay on schedule.

Side Effects and Safety

• Common: dizziness, lightheadedness, fatigue, nasal congestion, headache, drowsiness, swelling of ankles, and nausea.
• First-dose effect: marked dizziness or fainting can occur after the first dose or after a dose increase.
• Blood pressure effects: orthostatic hypotension may cause falls, especially in older adults.
• Sexual effects: ejaculation changes or erectile issues may occur.
• Less common: palpitations, edema, or shortness of breath.
• Serious but rare: syncope, prolonged erection (priapism), allergic reaction (rash, swelling, breathing trouble).

Use caution with other blood pressure medicines, diuretics, and PDE5 inhibitors such as tadalafil or sildenafil, because additive blood pressure lowering can occur. Cataract surgery patients may be at risk of intraoperative floppy iris syndrome. Tell the eye surgeon about current or past alpha-blocker use. People with severe liver disease or a history of fainting may need extra monitoring or a different option. Alcohol can worsen dizziness.

Onset Time

Blood pressure lowering can begin after the first dose, with the strongest effect several hours after dosing. BPH symptom relief can appear within days, but full benefit often takes 2–4 weeks as the dose is adjusted. Consistent bedtime dosing supports steady response.

Compare With Alternatives

Selective alpha-1 blockers such as tamsulosin (Flomax®) and silodosin (Rapaflo®) mainly target urinary symptoms and tend to cause less blood pressure lowering. Alfuzosin (Uroxatral®) and doxazosin (Cardura®) are other options. Terazosin is nonselective, so it helps both BPH symptoms and blood pressure but can cause more dizziness in some patients.

For hypertension alone, ARBs or combinations may be chosen first. Options include Micardis® (telmisartan) or a diuretic-containing ARB such as Edarbyclor® (azilsartan/chlorthalidone). Patients who need both BPH symptom relief and blood pressure control may still prefer terazosin for its dual action. Those who experience dizziness may discuss more selective agents or a lower dose.

In men with enlarged prostates, 5-alpha-reductase inhibitors such as finasteride or dutasteride shrink prostate tissue over months. They can be used alone or with an alpha-blocker when long-term reduction in size is needed.

Combination Therapy

Terazosin is often combined with other antihypertensives, such as thiazide diuretics, ACE inhibitors, or ARBs, under prescriber guidance. Dose adjustments reduce the risk of low blood pressure.

Combining with PDE5 inhibitors requires care. Separate the doses and use the lowest effective PDE5 inhibitor dose to limit additive hypotension.

Patient Suitability and Cost-Saving Tips

Terazosin can suit adults with BPH symptoms, adults needing an add-on for high blood pressure, and those who want once-daily dosing. It may not suit people with recurring syncope, severe liver impairment, or those unable to tolerate orthostatic changes. Before cataract surgery, eye surgeons should be informed about alpha-blocker use.

To manage costs, choose generic terazosin and consider larger supplies when appropriate. Multi-month packs often lower the per-month price. You can turn on simple reorder reminders in your account so you do not run short. For current offers and bulk options, check our terazosin discount page.
