What is prazosin and how does it work?

Prazosin hydrochloride is an alpha-1 adrenergic blocker in the quinazoline class. It is FDA-approved for one use: the treatment of hypertension (high blood pressure), to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and heart attacks. It can be used on its own or alongside other blood-pressure medicines. It is the generic equivalent of the brand Minipress.

Prazosin works by blocking postsynaptic alpha-1 adrenoceptors. That relaxes the muscle in the walls of your blood vessels, widening them and lowering the resistance your heart has to pump against. Unlike some other blood-pressure medicines, it usually does this without causing reflex tachycardia (a fast heartbeat in response to the drop in pressure). Doctors also prescribe prazosin off-label for other conditions, including nightmares and sleep disruption related to PTSD. Off-label means the FDA has not reviewed and approved prazosin for that purpose. Only your prescriber can decide whether it is right for you.

Prazosin cost and how the coupon works

Prazosin is available as a generic. Whether your pharmacy can substitute a generic for a brand prescription depends on your state's substitution laws and the product's therapeutic-equivalence rating, so ask your pharmacist how it works where you live. And being generic does not mean the price is the same everywhere. Cash prices for prazosin swing widely by pharmacy and by ZIP code, because each chain sets its own cash price. That is exactly why comparing matters, and why a coupon can make a real difference at one pharmacy and less of one at another.

To see what you would pay: enter your ZIP code above, pick your strength and quantity, and Rx.com will show today's prices across more than 60,000 U.S. pharmacies. Show the coupon at the counter. It is free, there is no membership required, and you can use it whether you are uninsured or simply paying cash because it beats your copay. Note that a discount coupon and insurance cannot be combined on the same fill, so ask the pharmacist to run whichever is lower. There is no manufacturer savings card for generic prazosin.

Prazosin alternatives and related medicines

Prazosin belongs to a family of alpha-1 blockers, and several relatives are commonly prescribed. Which one is right depends on the condition being treated, so this is a conversation for your prescriber, not a swap you should make on your own.

• Minipress — the brand name for prazosin hydrochloride.
• Doxazosin mesylate — a longer-acting alpha-1 blocker.
• Terazosin HCl — another alpha-1 blocker in the same quinazoline family.
• Tamsulosin HCl — an alpha blocker used for prostate symptoms.
• Clonidine HCl — a different class of blood-pressure medicine.

If your prescriber does switch you, check the price of the new drug here too. Costs between these medicines are not interchangeable, and the cheapest option at your pharmacy may not be the one you expect.

Prazosin safety and side effects

Prazosin does not carry a boxed warning. Its signature risk is the "first-dose effect": a sharp drop in blood pressure on standing (orthostatic hypotension) that can cause fainting with sudden loss of consciousness. Fainting episodes have usually occurred within 30 to 90 minutes of the first dose, and the same risk applies after a dose increase or when another blood-pressure medicine is added. This is why therapy starts at a low dose, often at bedtime, and is increased slowly. The manufacturer's patient information advises avoiding driving or performing hazardous tasks for the first 24 hours after you take prazosin or when your dose is increased.

Other things to know: dizziness, drowsiness, and palpitations are common. Prolonged erections and priapism are rare, but an erection lasting more than 4 hours needs immediate medical care, because untreated priapism can cause permanent damage. Intraoperative floppy iris syndrome has been observed during cataract surgery in some patients treated with alpha-1 blockers, the class prazosin belongs to, so tell your eye surgeon you take it before any procedure. The label notes there does not appear to be a benefit to stopping alpha-1 blocker therapy before cataract surgery, so do not stop on your own. Prazosin can add to the blood-pressure-lowering effect of PDE5 inhibitors such as sildenafil and tadalafil, other alpha blockers, and other antihypertensives. Use caution with alcohol, hot weather, and anything that leaves you dehydrated. This is a summary, not medical advice, and not a complete list of warnings. Read the leaflet from your pharmacy and talk with your doctor or pharmacist about your full medicine list.
