Topical Minoxidil Compounded vs Branded: A Clinical Comparison

At a glance

  • Branded Rogaine / FDA-approved OTC 2% solution [1], 5% solution [2] and 5% foam [4]
  • Generic OTC minoxidil / Approved under ANDAs [1]
  • Compounded topical / Extemporaneous topical forms not shown safe or effective, per oral tablet label [3]
  • Men's 5% solution / 1 mL twice daily, vertex only, not frontal baldness [2]
  • Women's 5% foam / Half a capful once daily [4]

What is the main difference?

Branded Rogaine is an FDA-approved OTC drug. The 2% solution was approved in 1988 and switched to OTC in 1996 [1]. Rogaine also has FDA-approved 5% solution and foam products [2][4], and generic OTC versions are approved under ANDAs [1]. Their labels fix the concentration, vehicle and directions. The men's 5% solution label directs 1 mL twice daily to the vertex only and says it is not for frontal baldness or a receding hairline [2]. The women's 5% foam label directs half a capful once daily [4].

The oral minoxidil tablet label says that using tablets to promote hair growth is not an approved indication, and that extemporaneous topical formulations have not been shown safe or effective [3].

What clinical evidence exists?

In a 48-week double-blind trial of 393 men, 5% topical minoxidil solution was superior to 2% solution and placebo for nonvellus hair count [5]. In a 16-week double-blind trial of 352 men, 5% minoxidil foam increased hair counts versus placebo (P<.0001) [6]. That foam trial collected no efficacy data past 16 weeks [6].

What do the OTC labels warn about?

The men's 5% solution label says for external use only, flammable, for men only, not for use by women or people under 18, and not for sudden or patchy hair loss, unknown cause, or a red, inflamed, infected, irritated or painful scalp [2]. The label includes a warning for people with heart disease [2]. The label lists chest pain, rapid heartbeat, faintness, dizziness, sudden unexplained weight gain, hand or foot swelling, scalp irritation or redness, unwanted facial hair growth, or no regrowth in 4 months as reasons to stop use [2]. The women's 5% foam label says extremely flammable and gives a 6-month check point [4].

What should a patient expect?

The labels say continued use is necessary to increase and keep hair regrowth, or hair loss will begin again [2][4]. The men's 5% solution label says results may occur at 2 months with twice-daily use, and some men may need at least 4 months [2]. The women's 5% foam label says results may occur at 3 months with once-daily use, and some women may need 6 months [4].

Frequently asked questions

Is compounded minoxidil as effective as Rogaine?
The oral minoxidil tablet label states that extemporaneous topical formulations have not been shown safe or effective [3]. Rogaine 2% and 5% products are FDA-approved OTC drugs [1][2][4].
What is the difference between the 5% solution and 5% foam?
Both are approved OTC products. The men's 5% solution label directs 1 mL twice daily to the vertex [2]. The women's 5% foam label directs half a capful once daily [4]. A 16-week trial of 5% foam in 352 men found increased hair counts versus placebo [6].
Can women use the men's 5% solution?
The men's 5% solution label says for use by men only and says do not use if you are a woman [2]. The OTC women's options are the 2% solution, used twice daily, and the 5% foam, used once daily [1][4].
What happens if I stop using minoxidil?
The OTC labels say continued use is necessary to increase and keep hair regrowth, or hair loss will begin again [2][4].
Does minoxidil work for frontal baldness?
The men's 5% solution label says it is not intended for frontal baldness or a receding hairline [2].
