When a commercial product can't meet your patient's clinical needs — the wrong strength, a filler they react to, a titration schedule a fixed dose can't support — we're the compounding partner you can build a plan around. LegitScript Certified, licensed in Texas and New Mexico, with a pharmacist you can reach directly to talk through strengths and titration.
Low-dose naltrexone (LDN) is naltrexone compounded at much smaller doses than the standard prescription — typically 1.5 to 4.5 mg. Because it isn't available commercially at these strengths, a compounding pharmacy prepares it to the exact dose your provider prescribes. LDN is used to support several conditions, as directed by your healthcare provider.
Naltrexone has been used for decades at much higher doses for something else entirely. At a fraction of that strength — usually 1.5 to 4.5 mg — it does a very different job. Research suggests that at these low doses it may help calm an overactive immune response and change how the body processes pain signals. That's why more providers explore LDN for people living with chronic pain, autoimmune conditions, and fibromyalgia — situations where a standard, one-size-fits-all medication often isn't the right fit.
Because no commercial product is made at these strengths, LDN has to be compounded. That's exactly what a 503A compounding pharmacy is for: a licensed pharmacist prepares the medication at the precise dose your provider prescribes, in a capsule or liquid built around you — not pulled off a shelf. As prescribed by your healthcare provider, it becomes a medication made for your situation, not the average of everyone else's.
Every capsule made to your provider's exact strength — 1.5 to 4.5 mg is where LDN lives.
Compounded low-dose naltrexone is prepared by licensed pharmacists in a LegitScript-certified pharmacy, as prescribed by your healthcare provider. It's made patient-specific — at a dose no commercial product offers — under Texas and New Mexico pharmacy licensure. It is not an FDA-approved product; compounded medications are prepared for a specific patient on a valid prescription.
Yes. Low-dose naltrexone is patient-specific and compounded only on a valid prescription from your healthcare provider. If you don't have one yet, start a consultation and we'll coordinate the details with your provider, so the medication is prepared to the exact dose they determine is right for you.
Thornhill's commonly compounds low-dose naltrexone in the 1.5 to 4.5 mg range, and to the precise strength your provider prescribes. Because these low doses aren't available in a commercial product, compounding lets us match your provider's plan exactly — in a capsule or liquid form built around what works for you.
Side effects of low-dose naltrexone are generally reported as mild and may include vivid dreams, sleep changes, or headache, especially when starting. Your provider determines whether LDN is appropriate for you and how to dose it, and your Thornhill's pharmacist can talk through what to expect. Always follow your provider's guidance.
The cost of compounded low-dose naltrexone depends on the dose, form, and quantity your provider prescribes, since each prescription is prepared patient-specific. Because it isn't a commercial product, pricing isn't a fixed shelf price — talk to a Thornhill's pharmacist and we'll walk you through your specific prescription.
Low-dose naltrexone is sometimes discussed in the context of weight management, but it's prescribed by your healthcare provider based on your individual situation, not as a standalone weight-loss product. If weight management is your goal, our medical weight-loss consultations are a better starting point. As always, your provider directs your care.
