Ever wondered why your doctor prescribed terazosin? It’s an alpha‑blocker that relaxes blood vessels and the prostate muscle. That double action makes it useful for high blood pressure and an enlarged prostate (BPH). If you’re new to the drug, this guide breaks down the basics, dosing tricks, and red flags you should know.
Terazosin works by blocking alpha‑1 receptors. In the arteries, this widens the vessels so blood flows easier, lowering your pressure. In the prostate, it eases muscle tone, helping you pee more smoothly. Because it tackles two problems at once, many people with both hypertension and BPH end up on the same pill.
Start low and go slow. Most doctors begin with 1 mg at bedtime to reduce the chance of dizziness. If you tolerate it, the dose may be raised to 2 mg after a week, then up to 5 mg as needed. Some folks stay on 2 mg, others go as high as 10 mg for tougher blood pressure control. Always follow your prescriber’s schedule—don’t jump doses on your own.
Take terazosin with a full glass of water. If you feel light‑headed the first few days, sit or lie down until it passes. Avoid alcohol or other blood‑pressure meds that can amplify the drop. And remember: consistency matters. Skipping doses can cause a rebound rise in pressure.
Common side effects are usually mild: a sudden drop in blood pressure when you stand up (orthostatic hypotension), a headache, or a dry mouth. If any of these linger more than a week, give your doctor a call. Rare but serious signs include a fast or irregular heartbeat, severe dizziness, or an allergic rash. Seek medical help right away if you notice swelling of the face or trouble breathing.
Terazosin can interact with several drugs. Antihypertensives, nitroglycerin, and other alpha‑blockers may push your pressure down too low. Certain antibiotics like ciprofloxacin can raise terazosin levels, increasing side effects. Always share a full medication list with your prescriber, including over‑the‑counter pills and supplements.
Pregnant or nursing moms should avoid terazosin unless the benefits clearly outweigh the risks. It’s also not the first choice for people with severe liver disease, because the liver helps clear the drug.
Tips to stay comfortable: rise slowly from sitting or lying down, keep a water bottle handy, and track your blood pressure at home. If you’re on the higher dose, your doctor may ask for blood tests to check kidney function now and then.
In short, terazosin can be a handy tool for controlling blood pressure and easing prostate symptoms, but it works best when you take it exactly as directed and stay alert to side effects. Got a question about your dose or a new symptom? Reach out to your healthcare provider—better safe than guessing.
