Minoxidil is one of the most familiar names in hair loss care. Most people know it as the foam or liquid sold over the counter. Compounded minoxidil is something different: a prescription formulation prepared by a pharmacy for one specific patient. This guide explains what that means, why a provider might prescribe it, and what to know before you start.
Minoxidil over the counter vs by prescription
Topical minoxidil is available without a prescription in standard 2% and 5% products, and it is FDA-approved for hereditary hair loss. Those products come in fixed strengths and fixed formulas, the same for everyone who buys them.
Minoxidil is also used in prescription forms. Oral minoxidil, for example, is FDA-approved to treat high blood pressure, and its use for hair loss is off-label, which means a provider prescribes it for a use outside its approved label based on their clinical judgment. For a closer look at the difference between the two routes, see topical versus oral minoxidil.
What "compounded" means
Compounding is when a licensed pharmacy prepares a medication for an individual patient, based on a prescription. Instead of a one-size-fits-all product, the pharmacy makes the formulation the provider specified for that person.
Because they are made individually, compounded medications are not FDA-approved. The FDA does not review compounded formulations for safety, effectiveness or quality before they are dispensed the way it reviews approved drugs. That is why it matters that compounding is done by a licensed pharmacy and only on a provider's prescription.
Why a provider might prescribe compounded minoxidil
A provider may choose a compounded formulation when a standard product is not a good fit. Common reasons include:
- Irritation from the standard base. Some people react to ingredients in retail solutions, such as propylene glycol. A pharmacy can prepare minoxidil in a different base.
- Combining ingredients. A provider may prescribe minoxidil alongside other prescription ingredients in a single formulation, rather than several separate products.
- A different form or strength. The provider can specify a form or strength that is not sold over the counter, based on your history.
Whether any of these apply to you is a decision for your provider after reviewing your health history. Compounded treatment is not automatically better than an over-the-counter product. It is a way to tailor treatment when there is a reason to.
Possible side effects
Like any medication, minoxidil can cause side effects. With topical use, the most common are scalp irritation, itching, dryness or flaking. Some people notice unwanted hair growth where the product touches the face. Some also notice increased shedding when they first start. Oral forms carry different considerations, which is one reason they require a prescription and a provider's review of your medical history.
Minoxidil is not for everyone. It is generally not recommended during pregnancy or breastfeeding, and certain heart conditions and medications need to be discussed with a provider first. Always follow your provider's instructions, and report side effects to your care team.
How compounded minoxidil is prescribed online
With telehealth, the process looks like this:
- You complete an online intake covering your hair loss, health history and medications, and upload photos of your scalp.
- A licensed provider reviews your case and decides whether treatment is appropriate and which formulation fits.
- If prescribed, a licensed pharmacy prepares your formulation individually and ships it to you with your provider's instructions.
