What hydrochlorothiazide costs if you have no insurance

What hydrochlorothiazide is for

According to MedlinePlus, a health site from the National Library of Medicine, hydrochlorothiazide treats high blood pressure. It also treats edema, which is extra fluid held in the body. It is a diuretic, also called a water pill, because it makes the kidneys remove extra water and salt in the urine. It comes as a tablet, a capsule or a liquid.

MedlinePlus explains that untreated high blood pressure can damage the brain, the heart and the kidneys. The Centers for Disease Control and Prevention says it usually has no signs or symptoms. Many people do not know they have it. Medicines for it are often taken for a long time, so a low price helps.

What a fill costs

The best government price we found for a real prescription fill comes from the Centers for Medicare and Medicaid Services. Its Part D spending report for 2024 counts what the drug plan and the member paid together for each fill. For plain hydrochlorothiazide, that came to about $4.40 per fill, and a fill held about 76 tablets. Medicare is the federal program that gives health coverage to people 65 and older and to some younger people with disabilities. Its plans negotiate prices, so your cash price may be a little higher or lower.

A fill of about 76 tablets for about $4.40 works out to roughly 6 cents a tablet. That is a bit higher than what pharmacies pay for the tablets, and the difference gives you a rough feel for what the pharmacy adds. Your own fill may have a different number of tablets.

What pharmacies pay for each tablet

The same agency surveys pharmacies each week to learn what they pay to buy drugs. The survey is called NADAC, and it tracks the average price pharmacies pay. It does not show shelf prices, but it shows how little the medicine itself costs. These numbers are for the week of October 21, 2026, and each price is for a generic.

• The 25 mg tablet cost pharmacies about 1.1 cents each.
• The 12.5 mg capsule cost about 2.7 cents each.
• The 12.5 mg tablet cost about 3.6 cents each.
• The 50 mg tablet cost about 3.1 cents each.

To estimate a month, multiply the price per tablet by the number of tablets on your prescription. As an example, 30 tablets of the 25 mg strength come to about $0.34 at the survey price. Thirty tablets of the 50 mg strength come to about $0.93. Your doctor decides the strength and the number of tablets, and we use these numbers only as a rough guide.

At the counter you will pay more than the survey price, because the pharmacy adds a fee and covers its own costs. The gap differs from store to store, so a few calls can show a big difference. Our guide on asking for the cash price gives you a script to read from.

Every plain hydrochlorothiazide row in the survey is a generic, and the Food and Drug Administration says competition among generic makers tends to lower prices. A generic has the same active ingredient as a brand-name medicine.

Combination pills cost more

Many blood pressure pills mix hydrochlorothiazide with a second medicine. The names of these pills list two medicines. They are priced on their own, and they cost more than the plain tablet. In the 2024 Medicare data, generic combination pills averaged about $23 to $33 per fill. The brand-name combination pills in that report averaged about $640 to $860 per fill.

Your prescriber may have good reasons to use a combination pill. If the price is a problem, please tell the office and ask what the choices are. Do not split, skip or switch pills on your own. Our guides on lisinopril costs and losartan costs cover two of the medicines that are often paired with it.

Other ways to spend less

At a community health center, the fee is set on a sliding scale. That means it goes up or down with your income and family size. These centers serve everyone, even people who cannot pay, according to the Health Resources and Services Administration. If you want to find one, our guide on community health centers can help.

The medicine is cheap, and the doctor visit to renew it is often the bigger cost. Ask the pharmacy whether a larger fill changes the price per tablet. Your prescriber decides how many tablets to write, so ask the office if a longer supply is possible. With a monthly membership, a cash-pay doctor can check your blood pressure and renew a prescription as often as you need. With direct primary care, you usually pay $50 to $200 a month, and our directory lets you see cash-pay doctors in your area.

Please do not stop it on your own

MedlinePlus says to keep taking hydrochlorothiazide even if you feel well, and not to stop without talking to your doctor. If cost is the problem, call your prescriber or pharmacist before you run out and say so. Please do not skip tablets to stretch a supply.
