# Minoxidil

Minoxidil is FDA-approved on the scalp as Rogaine to regrow hair, and as a tablet for severe high blood pressure. For the scalp products the evidence grade is strong-human. Pills for hair loss are not an approved use. The tablet label warns of fluid around the heart.

| Label dosing | From the Rogaine and Loniten labels. Rogaine 2% and 5% solution: 1 mL on the scalp 2 times a day. Men's Rogaine foam: half a capful on the scalp 2 times a day. Women's Rogaine foam: half a capful once a day. The labels say using more or more often will not improve results, and regrowth takes months. Loniten tablets for severe high blood pressure, over 12 years of age: 5 mg once a day to start, usually 10 to 40 mg a day, at most 100 mg a day, usually with a diuretic and a beta-blocker. The prescriber sets the dose. | primary | 2026-10-26 | [source](https://www.accessdata.fda.gov/drugsatfda_docs/label/2015/018154s026lbl.pdf) |

## Short answer

Minoxidil is FDA-approved on the scalp as Rogaine to regrow hair, and as a tablet for severe high blood pressure. For the scalp products the evidence grade is strong-human. Pills for hair loss are not an approved use. The tablet label warns of fluid around the heart.

Source: https://peptideindex.ai/methodology#short-answer

## Known risks

- The tablet label opens with its strongest warning. The tablet can cause fluid around the heart, sometimes pressing on it, and can make chest pain worse [^2].
- Fluid around the heart was seen in about 3% of tablet users who were not on dialysis [^2].
- The tablet makes the body hold salt and water. Without a water pill, this can cause swelling and heart failure [^2].
- The tablet speeds up the heart. Chest pain may start or get worse [^2].
- About 8 in 10 people on the tablet grow longer, darker body hair, often first on the face [^2].
- Extra hair on newborns has been reported after tablet use in pregnancy. The label says not to give it to a nursing woman [^2].
- The scalp products say to stop and ask a doctor for chest pain, a fast heartbeat, faintness, dizziness, sudden weight gain or swollen hands or feet [^1].
- Itching and skin irritation are the most common problems with the scalp products. Unwanted facial hair can grow [^1].
- The scalp product labels say it may be harmful in pregnancy or breast-feeding. It is not for anyone under 18 [^1].
- Pets can be poisoned by contact with scalp products. In one review of poison center cases, 8 of 62 sick cats died [^19].
- In a study of 1,404 people on low-dose pills for hair loss, 15.1% grew extra body hair. Light-headedness, fluid build-up and a fast heartbeat were less common [^18].
- In 2020, compounded hair loss capsules were recalled because they held minoxidil not listed on the label. The notice cited 33 reports of a fast heart rate, dizziness or low blood pressure [^9].

## What nobody knows yet

- No pill has been through FDA review for hair loss. The tablet label says growing hair is not an approved use [^2].
- The 2021 safety study of low-dose pills looked back at records and had no comparison group. Long-term heart effects in healthy people are not settled [^18].
- Few trials compare pills with the scalp products. A 2021 trial in 72 women found no clear difference between them [^16] [^22].
- The 5% solution label says regrowth has not been shown to last past 48 weeks in large trials [^1].
- Minoxidil caused heart damage in dogs, rats and minipigs. The tablet label says what this means for people is not clear [^2].
- It is not clear how well pills help women. A 2020 review of 10 studies counted 19,003 men and only 215 women [^17].

## What it is

Minoxidil is a drug that widens small blood vessels [^2]. It is not a peptide. FDA first approved it in 1979 as a tablet for high blood pressure [^6]. Researchers saw that people taking it grew extra hair [^2] [^22].

Today it comes in two forms. Rogaine solution and foam go on the scalp to regrow hair, with no prescription needed [^1] [^3] [^5]. Rogaine was approved in 1988 and moved off prescription in 1996 [^3]. The tablet needs a prescription and is approved for severe high blood pressure [^2]. Some doctors now prescribe low-dose pills for hair loss, which is not an approved use [^2] [^22].

Source: https://www.accessdata.fda.gov/drugsatfda_docs/label/2015/018154s026lbl.pdf

## Where it stands legally

Minoxidil is FDA-approved: Drugs@FDA lists Rogaine products for the scalp and Loniten tablets taken by mouth [^3] [^4] [^5] [^6]. The scalp products are approved to regrow hair on the scalp, and they are sold without a prescription [^1] [^3]. The tablets are approved only for severe high blood pressure that other drugs did not control [^2]. The approval does not cover pills for hair loss. The tablet label says using it in any form to grow hair is not an approved use [^2]. Checked 26 October 2026.

Loniten, the brand-name tablet, is listed as discontinued. Drugs@FDA notes a Federal Register finding that it was not stopped for safety or effectiveness reasons [^6]. In October 2024, FDA posted draft advice for companies that want to make generic minoxidil tablets [^7].

Pharmacies may compound with a raw substance that meets a USP standard or is part of an FDA-approved drug [^10]. A compounded drug is not FDA-approved, and FDA does not review its quality before sale [^13]. Minoxidil is not on FDA's 503A category list [^11]. It is not among the substances FDA says may present significant safety risks [^12].

Source: https://www.accessdata.fda.gov/scripts/cder/daf/index.cfm?event=overview.process&ApplNo=019501

## What the evidence shows

The evidence grade is strong-human for the scalp products in hair loss [^1] [^14] [^15]. In a 48-week trial of 393 men, the 5% solution grew more hair than the 2% solution or a dummy liquid [^14]. Itching and irritation were more common with 5% [^14]. In a 16-week trial of 352 men, the 5% foam grew more hair than a dummy foam [^15]. In label studies of women, 19% saw moderate regrowth after 8 months, against 7% on a dummy liquid [^1].

For severe high blood pressure, the tablet lowered blood pressure to the label's target in about 75% of patients [^2]. Most of them had blood pressure other drugs could not control [^2].

The evidence for pills for hair loss is thinner. A 2020 review of 10 studies found most people with common hair loss improved [^17]. A 2021 trial in Iran gave 72 women a low-dose pill or the 2% solution for 9 months [^16]. Hair density rose in both groups, with no clear difference between them [^16]. A 2021 study of 1,404 people on low-dose pills found few stopped because of harms, but it had no comparison group [^18]. A phase 3 trial of minoxidil taken by mouth in men is planned in Brazil [^21]. In dogs and cats, even small contact with scalp products caused illness [^19].

## Legitimate ways to get it

The legal way to use minoxidil for hair loss is a Rogaine product on the scalp, sold without a prescription [^1] [^3] [^4] [^5]. Each Rogaine product is a reference drug for generic copies [^3] [^4] [^5].

Minoxidil tablets need a prescription, and they are approved only for severe high blood pressure [^2]. A doctor may prescribe them for hair loss, but that use is not approved [^2] [^22].

Pharmacies may compound with a raw substance that is part of an FDA-approved drug [^10]. A compounded drug is not FDA-approved, and FDA does not check it before sale [^13].

One US study in Ohio is recruiting people with breast cancer whose hormone treatment caused hair loss [^20]. It compares minoxidil taken by mouth with foam on the scalp [^20]. The trials block on this page lists open trials with their dates.

Source: https://clinicaltrials.gov/study/NCT05417308

## How people are getting it anyway

This section describes what happens and is not a recommendation.

Telehealth companies prescribe low-dose minoxidil pills for hair loss, often after an online form [^22]. The tablets are approved only for severe high blood pressure, so this use is not approved [^2]. Skin doctors quoted by AP said a visit in person, with a blood pressure check, is better [^22].

Some pharmacies and online sites also sell scalp mixes of minoxidil and finasteride [^8]. FDA says no topical product with finasteride, alone or mixed, is FDA-approved [^8]. From 2019 to 2024, FDA got 32 reports of harm from these finasteride products, alone or mixed [^8].

In 2020, compounded finasteride capsules for hair loss were recalled [^9]. Testing found minoxidil not listed on the label, at levels above approved products [^9]. The notice cited 33 reports of a fast heart rate, fluid build-up, dizziness or low blood pressure [^9].
