Most people meet minoxidil as a liquid or foam you rub into the scalp. It also comes as a tablet. Low-dose oral minoxidil is the same medicine taken by mouth, and for some people it is easier to stick with and reaches the whole scalp at once. We prescribe it for men and women, after a proper check.

The same drug, a lower dose

Minoxidil started life as a blood-pressure tablet. People taking it grew more hair, and that side effect became a hair-loss treatment. For hair loss we use a much lower dose than the blood-pressure one, which is why the side effects are usually mild. Using it this way is off-label, which is routine in everyday medicine, and we explain what that means so the choice is yours.

How it works

Minoxidil widens small blood vessels and lengthens the growing phase of the hair follicle. As a tablet it works across the whole scalp, so you are not relying on an even coat from a bottle every day. Results take three to six months and depend on staying on it, the same as the topical.

Who it suits

It is worth considering if you have not got on with the topical, find the twice-a-day routine a chore, or your scalp reacts to the liquid. It can be used on its own or alongside finasteride or dutasteride. It is not right for everyone, which is why we check your heart and blood-pressure history first.

Men and women

Low-dose oral minoxidil is used in both men and women. The main thing to know is that it can increase fine body or facial hair in some people. This is dose-related and settles when you stop. We start low and review, and you decide whether the trade-off suits you.

Safety and monitoring

Because it began as a blood-pressure drug, the things we watch for are fluid retention and ankle swelling, a faster heartbeat, and light-headedness, more likely at higher doses. We do not start it with significant heart disease or uncontrolled blood pressure, and we avoid it in pregnancy and breastfeeding. We take a baseline, start at a low dose, and review. Tell us promptly about ankle swelling, breathlessness, palpitations or dizziness.

What to expect

Give it three to six months before judging it, keep taking it to keep the result, and expect a little extra shedding early on, just as with the topical. If you would like to consider it, you can read about oral minoxidil on our pharmacy page, and a doctor will confirm whether it is right for you.
