Low-dose oral minoxidil: a hair loss tablet for men and women

Oral minoxidil is an FDA-approved generic tablet for severe high blood pressure. Physicians prescribe it at much lower doses for pattern hair loss in men and women, which is off-label: the FDA has not approved it for hair. In a study of 1,404 people taking it for hair loss, the most common side effect was unwanted facial or body hair. A US-licensed physician decides whether it fits you after checking your heart and blood pressure history.

Who it may be for

  • Men and women with pattern hair loss who would rather take a tablet than use a scalp product every day.
  • People whose scalp did not tolerate topical minoxidil, or who found a twice-a-day scalp routine hard to keep.
  • People with normal blood pressure and no heart disease, who can watch for swelling or a fast heartbeat.

Only your physician can decide whether it is appropriate. A prescription is not guaranteed.

Who it is not for

  • Anyone with pheochromocytoma, a rare adrenal tumor: the label rules minoxidil out.[1]
  • People with heart disease, heart failure, chest pain (angina), very low blood pressure or fluid around the heart in the past, unless their own heart doctor agrees.[1]
  • Anyone breastfeeding: the label says minoxidil tablets should not be given to a nursing woman. Anyone pregnant or planning to be should say so first.[1]
  • Anyone already taking blood pressure medicine should say so first, because minoxidil lowers blood pressure too.[1]

How it works

Minoxidil widens small blood vessels, which is how it lowers blood pressure. Extra hair growth (hypertrichosis) was noticed as a side effect: at blood pressure doses it appears in about 80% of people within 3 to 6 weeks. For hair loss, physicians prescribe far lower doses than for blood pressure. Exactly how it grows hair is not fully understood.[1]

How long it takes

There is no FDA timeline for minoxidil tablets in hair loss. For minoxidil on the scalp, the American Academy of Dermatology says it usually takes about 6 to 12 months to show its effect, and some people shed more in the first weeks. The trial comparing the tablet with scalp solution ran 24 weeks. Any benefit lasts only while you keep taking it.[2][3][4]

Tablet or scalp solution?

In a randomized, double-blind trial of 90 men, a daily minoxidil tablet was compared with 5% minoxidil solution on the scalp for 24 weeks. The tablet was not shown to be better overall; photo ratings favored it at the crown but not at the front.[4]

Side effects and safety

  • In 1,404 people taking low-dose oral minoxidil for hair loss: unwanted facial or body hair 15.1%, lightheadedness 1.7%, fluid retention 1.3%, fast heartbeat 0.9%, headache 0.4%, swelling around the eyes 0.3% and trouble sleeping 0.2%. 1.7% stopped because of side effects, and no life-threatening effects were seen.[5]
  • At blood pressure doses, its label carries a boxed warning: it can cause fluid around the heart (pericardial effusion), occasionally serious, and can worsen angina. One case of fluid around the heart and lungs has been reported at a low hair-loss dose; it resolved after stopping.[1][6]
  • Get medical care right away for chest pain, shortness of breath, fainting, sudden weight gain, or swelling of your face, hands, feet or ankles.[1]

Common questions

Is oral minoxidil FDA-approved for hair loss?

No. Minoxidil tablets are FDA-approved for severe high blood pressure, and their label says using them to grow hair is not an approved use. Physicians prescribe low doses for hair loss off-label.

Can women take oral minoxidil for hair loss?

Yes, if a physician decides it fits. Of 1,404 people in the largest safety study of low-dose oral minoxidil for hair loss, 943 were women. It is not used while breastfeeding, and women are asked about pregnancy first.

What is the most common side effect?

Unwanted hair on the face or body. It was reported by 15.1% of people in a study of 1,404 taking low-dose oral minoxidil for hair loss, and led very few to stop.

Will oral minoxidil lower my blood pressure?

It can. Minoxidil is a blood pressure medicine, and lightheadedness was reported by 1.7% of people taking low doses for hair loss. Your physician asks about your blood pressure, heart and current medicines first.

Is oral minoxidil better than minoxidil on the scalp?

Not clearly. In a 24-week randomized trial of 90 men, the tablet was not shown to be better than 5% minoxidil solution overall. Some people simply find a tablet easier to keep taking.

Does oral minoxidil cause shedding at first?

Some people shed more in the first weeks of starting minoxidil. The American Academy of Dermatology describes this shedding, with minoxidil on the scalp, as temporary.

Can I get oral minoxidil online?

Yes, with VevaMD: a US-licensed physician from Beluga Health, P.A. reviews your intake, including your heart and blood pressure history, and decides whether it fits you.
