  • US status, topical 2% and 5% / Over-the-counter drugs [2]
  • US status, minoxidil tablets / Prescription-only, for severe hypertension [1]
  • Hair growth as an indication / Not approved for minoxidil tablets [1]

What is minoxidil's legal status in the US?

Two different products share the name, and only one is the hair product.

Rogaine 2% solution, for men and women, was first approved on 08/17/1988; the Rx-to-OTC switch was approved on 02/09/1996, and Drugs@FDA lists it as over-the-counter [2].

Minoxidil tablets are prescription antihypertensives reserved for severe hypertension that is not controlled with a diuretic and two other antihypertensive drugs. Their labeling states that using minoxidil tablets to promote hair growth is not an approved indication [1].

Does 'minoxidil' always mean the topical?

No. The tablet and the topical are separate products with different regulatory status. The tablet label also states that extemporaneous compounded topical formulations have not been shown to be safe or effective and share the full contraindications, warnings and adverse reactions of the label, because systemic absorption can occur [1].

What the OTC labels say

The US men's 5% solution label describes 1 mL twice daily on the vertex for men, while the women's 5% foam label describes half a capful once daily. Both labels say that continued use is needed to maintain regrowth [3][4].

The labels list heart disease among their warnings. They also name chest pain, rapid heartbeat, faintness, dizziness, sudden unexplained weight gain, swelling of the hands or feet, scalp irritation or redness, and unwanted facial hair growth as reasons to stop use [3][4].

Is 5% stronger than 2%?

In a 48-week double-blind trial of 393 men, 5% topical minoxidil solution was significantly superior to 2% solution and placebo after 48 weeks, with more itching and local irritation reported with 5% [5].

Frequently asked questions

Is topical minoxidil 5% over the counter in the US?
Yes. The Men's Rogaine Extra Strength 5% solution carries an over-the-counter Drug Facts label [3]. Drugs@FDA lists Rogaine 2% solution as over-the-counter, with the prescription-to-OTC switch approved 02/09/1996 [2].
Do I need a prescription for minoxidil tablets?
Yes. Minoxidil tablets are prescription antihypertensives for severe hypertension, and their labeling states that using them to promote hair growth is not an approved indication [1].
Can women use 5% minoxidil?
The 5% solution is labeled for men only. Women's options on the US over-the-counter labels are the 2% solution twice daily or the 5% foam once daily [3][4].
Are generic minoxidil products equivalent to Rogaine?
Over-the-counter drugs in Drugs@FDA do not receive therapeutic equivalence ratings and may not be interchangeable, even at the same strength and dosage form [2].
