Hytrin® (Terazosin) Uses, Dosing, and Savings

What Hytrin® (Terazosin) Is and How It Works

Terazosin is an alpha-1 blocker. It relaxes smooth muscle in the prostate, bladder neck, and blood vessels. This helps ease urinary symptoms from benign prostatic hyperplasia (BPH) and lowers blood pressure in hypertension. It comes as oral tablets or capsules in 1 mg, 2 mg, 5 mg, and 10 mg strengths, including terazosin HCl 2mg. Dosing is once daily, often at bedtime to reduce dizziness.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; prescriptions are reviewed by licensed pharmacists before dispensing. We source from licensed, vetted partner pharmacies so you receive authentic brands and generics at fair prices and with a wide selection.

Terazosin blocks alpha-1 receptors in the prostate and vascular smooth muscle. This reduces urethral resistance and lowers systemic vascular resistance. It does not shrink the prostate. For hypertension, it can be used with other agents when extra control is needed.

Common uses include BPH symptom relief and support for blood pressure control. Some clinicians may use it off-label to help pass certain kidney stones by relaxing ureteral smooth muscle. Your prescriber decides if it fits your treatment plan.

Dosage and Usage

• Starting dose for BPH: 1 mg at bedtime.
• Titration for BPH: increase gradually (for example to 2 mg, 5 mg, and if needed 10 mg once daily) at intervals set by your prescriber.
• Starting dose for hypertension: 1 mg at bedtime. Usual range 1–5 mg once daily; some patients need higher doses.
• Take the dose at the same time each day. Bedtime dosing helps limit lightheadedness.
• Swallow tablets or capsules whole with water. Do not crush or chew.
• If you miss a dose, take it when remembered unless it is close to the next dose. Do not double up.
• If you stop terazosin for several days, contact your prescriber before restarting. You may need to restart at 1 mg due to the first-dose effect.
• Stand up slowly from sitting or lying positions to reduce dizziness or fainting.
• Tell your ophthalmologist you use an alpha-1 blocker before cataract surgery due to a risk of intraoperative floppy iris syndrome.

• Storage: store at 15–30 °C (59–86 °F) in a dry place. Keep in the original container with the lid closed.
• Protect from moisture and excess heat. Do not store in a bathroom.
• For travel, keep medicine in your carry-on. Bring enough doses for your trip plus a few extra days.
• Use a pill organizer if helpful. Keep the label and prescription details with you.
• Do not use after the expiration date.

Benefits and Savings

Terazosin helps reduce BPH symptoms like weak stream, hesitancy, and nighttime urination. Many patients notice improvements after dose titration. For hypertension, it helps lower blood pressure as part of a combination plan.

Once-daily dosing is convenient. Multiple strengths support careful titration from 1 mg to 10 mg. Options include terazosin 1 mg tablet, terazosin HCl tablet 2 mg, terazosin 5 mg tablet, and terazosin 5mg capsules. Your prescriber chooses the form and strength that fit your needs.

Buying at Canadian prices can lower the terazosin cost. Typical savings are 60–80% versus common US pricing. Multi-month supplies and bulk promotions can reduce the per-month terazosin price further. You can set reorder reminders so you do not run out.

We carry both brand and generic options when available, and we ship to the US with secure handling.

Side Effects and Safety

• Dizziness or lightheadedness, especially after the first dose or a dose increase
• Orthostatic hypotension (drop in blood pressure when standing)
• Headache, fatigue, or weakness
• Nasal congestion
• Nausea
• Palpitations or peripheral edema
• Rare: drowsiness or blurred vision

Serious but uncommon risks include fainting (syncope), priapism (painful, prolonged erection), and severe hypotension. Intraoperative floppy iris syndrome can occur during cataract surgery. Use caution with other blood pressure medicines and with PDE5 inhibitors like sildenafil or tadalafil, as these can increase dizziness or low blood pressure. Avoid driving until you know how terazosin affects you.

Onset Time

Some blood pressure lowering can occur within hours of the first dose. Dizziness is most likely after initial dosing and after increases. For BPH, symptom relief often begins within a few days as the dose is adjusted. The full effect may take 2–6 weeks at a steady dose. Your prescriber will adjust the dose based on response and tolerance.

Compare With Alternatives

Tamsulosin is another alpha-1 blocker used for BPH. It is more selective for the prostate and may cause less orthostatic dizziness. It is not typically used for blood pressure. Terazosin can help both BPH and hypertension, which may suit some patients.

Doxazosin is similar to terazosin and is dosed once daily. Side effects and precautions resemble terazosin. Choice often depends on response, tolerability, and cost.

For hypertension, first-line classes are usually thiazide diuretics, ACE inhibitors, angiotensin receptor blockers, and calcium channel blockers. Options include combinations like Hyzaar® and calcium channel blockers such as Norvasc®. Your clinician considers your overall risk, comorbidities, and current regimen.

For BPH with a large prostate, a 5-alpha-reductase inhibitor (finasteride or dutasteride) may be added to reduce prostate size over months. Terazosin can provide earlier symptom relief while the second agent takes effect.

Combination Therapy

• Terazosin plus a thiazide diuretic, ACE inhibitor, ARB, or calcium channel blocker for hypertension. Monitor for low blood pressure and adjust doses.
• Terazosin plus a 5-alpha-reductase inhibitor (finasteride or dutasteride) for BPH with enlarged prostate. This may improve symptoms and reduce progression.
• Use caution if combined with PDE5 inhibitors (sildenafil, tadalafil). Start low and separate dosing to reduce dizziness.
• Avoid duplicate alpha-blockers. Do not combine terazosin with tamsulosin, doxazosin, or alfuzosin.

Patient Suitability and Cost-Saving Tips

Terazosin may suit adults with BPH symptoms, especially those who also need help with blood pressure. It may also be used as an add-on for hypertension when other agents do not provide enough control. It is not usually the first choice for blood pressure alone.

It may not suit people with a history of fainting, severe orthostatic hypotension, or those at high risk of falls. Caution is needed in liver impairment. Discuss use if you are pregnant or breastfeeding. It is not approved for children. Tell your eye surgeon about alpha-blocker use before cataract surgery.

To manage terazosin cost, consider a larger supply if appropriate, which may lower the per-month price. Compare strengths such as terazosin tablets 2mg and terazosin 5mg price to see which pack sizes offer better value. Set a reorder reminder so you have time to process a new fill.

If you have questions about terazosin uses, terazosin for hypertension, or terazosin for high blood pressure, speak with your prescriber or pharmacist. They can review your other medicines and help reduce side effects like dizziness.
