At a glance

  • Drug / minoxidil topical 2% and 5% (Rogaine and store brands)
  • Regulatory status / Over the counter; the switch from prescription status was approved 02/09/1996 [1]
  • Men's 5% solution directions / 1 mL twice daily, top of the scalp only, men only [2]
  • Women's 5% foam directions / Half a capful once daily [3]
  • Oral tablets / Prescription antihypertensive, approved for severe hypertension only [4]
  • Oral use for hair loss / Not an approved indication [4]
  • Account reimbursement / Not addressed in the minoxidil labeling or FDA records

The two products are regulated differently

FDA records list Rogaine 2% solution for men and for women as over the counter, and the switch from prescription to OTC status was approved on 02/09/1996 [1]. The men's 5% solution is likewise an OTC Drug Facts product, labeled for the top of the scalp only and not for frontal baldness or a receding hairline [2].

Minoxidil tablets are a different product in a different regulatory category: a prescription antihypertensive approved for hypertension that is symptomatic or associated with target organ damage and not manageable with maximum doses of a diuretic plus two other antihypertensive drugs [4]. The tablet label states that use of minoxidil, in any formulation, to promote hair growth is not an approved indication [4].

Oral minoxidil for hair loss is off-label and still carries the tablet label

Low-dose oral minoxidil for hair loss is off-label. It is still taken as minoxidil tablets, which carry a boxed warning [4]. Trials have tested it for androgenetic alopecia at 1 mg a day [5] and 5 mg a day [6]. The 5 mg trial was a 24-week double-blind randomized study of 90 men comparing oral minoxidil 5 mg daily with topical 5% twice daily; 68 men completed, and the between-group differences in frontal and vertex terminal hair density were not statistically significant [6].

Where the reimbursement question sits

The minoxidil labels and the FDA approval records cover directions, warnings and approval status. They say nothing about health savings accounts, flexible spending accounts, employer reimbursement or letters of medical necessity. What they do settle is which product is which: a bottle of 5% solution, a women's 5% foam, and minoxidil tablets are three separate labeled products [2][3][4].

Frequently asked questions

Is topical minoxidil 5% a prescription drug?
No. Rogaine 2% solution for men and for women is listed as over the counter in FDA records, and the switch from prescription status was approved 02/09/1996 [1]. The men's 5% solution is also an OTC Drug Facts product [2].
Is oral minoxidil approved for hair loss?
No. Minoxidil tablets are approved for hypertension, and the tablet label states that use of minoxidil, in any formulation, to promote hair growth is not an approved indication [4].
Which minoxidil products are labeled for women?
FDA records list a 2% solution for women as over the counter [1]. The women's 5% foam label directs half a capful once daily [3]. The 5% solution is labeled for men only [2].
How long does topical minoxidil take to work?
The men's 5% solution label says results may occur at 2 months with twice-daily use and that some men may need at least 4 months [2]. The women's foam label says results may occur at 3 months with once-daily use, and some women may need at least 6 months before seeing results [3].
Does the boxed warning apply to low-dose oral minoxidil for hair loss?
The boxed warning is part of the minoxidil tablet labeling [4]. Hair-loss use is off-label and is still use of the tablets. Trials have tested 1 mg a day [5] and 5 mg a day [6].
