How to Get a Prescription for Low-Dose Oral Minoxidil (2026 Guide)

The short answer: you can't buy oral minoxidil over the counter at any strength. The precise low doses dermatologists prescribe for hair loss (0.625 mg, 1.25 mg, 1.875 mg) cannot be bought anywhere as manufactured products. Commercial tablets exist only in the 2.5 mg and 10 mg blood-pressure strengths. Low-dose oral minoxidil is a prescription, compounding-pharmacy medication: your prescriber sets the exact strength, and a pharmacy like ours prepares it as capsules. Here's the route from consult to capsule.

KeyPoints

• Commercial minoxidil tablets come only in 2.5 mg and 10 mg. There is no manufactured sub-2.5 mg product
• Oral minoxidil for hair loss is off-label and prescription-only; prescribers screen cardiovascular history first
• Exact low strengths (0.625, 1.25, 1.875 mg) are prepared by compounding pharmacies as capsules
• Cash-pay; we quote the price before we fill
• Generation Pharmacy compounds it in West LA but cannot prescribe it

EndKeyPoints

Why you can't buy it over the counter, or even at a regular pharmacy

Two distinct barriers. First, oral minoxidil is prescription-only. It was approved decades ago as a blood-pressure medication, and the hair-loss use is off-label, requiring prescriber judgment and cardiovascular screening. Second, even with a prescription in hand, a conventional pharmacy can only hand you what manufacturers make: 2.5 mg or 10 mg tablets. The modern dermatology practice of starting at 0.625–1.25 mg daily has no commercial product behind it. Every dose below 2.5 mg, and every intermediate step in a careful titration, is pharmacy-compounded by definition.

If you're still deciding between routes, our oral vs. topical minoxidil comparison lays out who tends to do better on each.

How to actually get it

1. Get a prescription. A dermatologist, your primary care physician, or a hair-loss telehealth provider reviews your health history, particularly cardiovascular, and chooses a starting strength if low-dose oral minoxidil fits.
2. Have them send it to a compounding pharmacy. Providers e-prescribe to Generation Pharmacy via SiPrescribe or fax the order; the prescribing guide has formulation language ready to copy.
3. Pick up or arrange delivery. Capsules are typically ready in 1–2 business days, pick up at 12203 W Pico Blvd in West LA or ask about delivery options within California.

Commercial vs. compounded: what exists where

What we compound

Our oral minoxidil capsules are prepared at exactly the strength your prescriber specifies, under USP 795 with certificates of analysis. Which makes the standard titration approach practical: start low, reassess at three to six months, and step the dose in small increments rather than doubling. Prescribers running combination protocols can also fold minoxidil into a single multi-ingredient capsule.

What does it cost?

Low-dose oral minoxidil is usually cash-pay since the use is off-label and the product compounded. Cost varies with strength and quantity, and we'll quote it before the prescription is sent, call 424-228-1049 or see the compounded medication cost guide for context.

Red flags to avoid

• No-prescription tablet websites: oral minoxidil is a cardiovascular-active drug, buying it from sites that skip the prescriber means nobody has screened your heart history
• Splitting blood-pressure tablets at home: quartering a small 2.5 mg tablet produces unpredictable doses of a medication where dose precision is the whole point
• Gray-market imports and "research" powders: unverified purity and potency, no USP standards, no pharmacist accountability

Next steps
