FAQ

Oral capsules are generally suitable for normal transportation when packed protectively. Keep them in their packaging and follow the labeled storage conditions of 68°F to 77°F, protected from light and moisture; after arrival, check the package and capsules for damage, moisture, leaks, or visible changes.

It can cause dizziness, sleepiness, or reduced alertness in some people. Avoid driving or hazardous tasks until the individual effect of the capsules is known.

Naltrexone is used with behavioral treatment for alcohol dependence and to help maintain opioid abstinence after detoxification. It is an opioid antagonist and is not used to treat opioid withdrawal while opioids are still in the body.

Description

LDN is the low-dose naltrexone capsule we carry for customers who have a prescription calling for the 1.5 mg strength. Naltrexone itself is an opioid receptor antagonist, and the dose a person is prescribed depends heavily on why it was prescribed. Our main buyer decision here is straightforward: we offer a single 1.5 mg capsule strength, so the real choice is which package quantity - 30, 60, 90, or 120 capsules - best matches the supply length a prescriber has recommended.

What LDN Is and How It Fits Into Naltrexone Therapy

Naltrexone blocks opioid receptors in the brain. Standard-dose oral naltrexone, commonly 50 mg once daily, is used as part of treatment for alcohol dependence and to block the effects of externally administered opioids after opioid withdrawal. Separately, much smaller doses - typically in the 1.5 mg to 4.5 mg range - may be prescribed off-label for conditions such as chronic pain and fibromyalgia and for some inflammatory or autoimmune conditions. This approach is often referred to as "low-dose naltrexone" or LDN, but the quality of evidence and its appropriateness vary by condition. Our 1.5 mg capsule is formulated for this low-dose approach rather than for a standard 50 mg regimen, which is an important distinction when comparing what we sell with other naltrexone products.

Whichever naltrexone product a prescriber selects, the active ingredient is the same molecule, though products labeled by brand and generic name can look different on the shelf. The comparison below shows what stays constant and what can vary between a brand-name naltrexone product and its generic counterpart.

Naltrexone, whether prescribed as naltrexone at standard strength or as a low-dose capsule like ours, can precipitate sudden, severe withdrawal if started while opioids remain in the body. A prescriber generally confirms an opioid-free interval before treatment; this is often at least 7 to 10 days after short-acting opioids, while people transitioning from buprenorphine or methadone may remain vulnerable for up to two weeks. The appropriate interval and any testing must be determined by the treating clinician.

Strength and Package Sizes We Offer

We currently list LDN in one supplied strength, 1.5 mg oral capsules, and we offer that strength in four package sizes: 30, 60, 90, and 120 capsules. Choosing a package size is really a question of how long a supply a customer wants on hand at one time - a 30-capsule pack covers roughly a month at a once-daily regimen, while the 90- or 120-capsule packs suit customers who prefer to reorder less often. The image below walks through the core identifying details of the capsule and its packaging so a customer can check what has arrived against what was ordered.

Because we only carry the 1.5 mg strength of this particular product, any dose adjustment above 1.5 mg would need to be discussed with a prescriber rather than solved by selecting a different package from our listing.

Ordering, Prescription Requirements, and Delivery

Naltrexone capsules are classified as prescription medication in the United States. Before checking out, customers should confirm that the selected strength and quantity match their prescription and review our current ordering instructions. Once we can process an order, our team packs and dispatches it, and our support staff is available every day, around the clock, by email, online chat, or phone if a customer has a question before or after the order ships. It also helps to confirm a few product and delivery details, which the checklist below summarizes.

We have operated as an online pharmacy since 2008, and our packing and dispatch process is built around getting each verified order out to the customer promptly. Customers managing chronic pain conditions may also want to browse our Pain Relief category, since several treatments there are sometimes considered alongside a low-dose naltrexone regimen.

Using, Storing, and Monitoring Your Capsules

Low-dose naltrexone regimens are commonly taken once daily. Some people take their dose in the evening, although sleep disturbance or vivid dreams may lead a prescriber to suggest a different time. Prescribers sometimes begin with a low dose such as 1.5 mg and titrate upward gradually over a period of weeks toward a maintenance dose of around 3 mg to 4.5 mg, guided by the individual's response. This is general information about how these off-label regimens are commonly managed, not a recommendation to change a specific dose without medical advice. Naltrexone can be taken with or without food; taking it with a small amount of food may reduce the mild nausea some people experience when they start.

Commonly reported side effects include nausea, headache, dizziness, fatigue, and sleep changes. Naltrexone must not be started during current opioid use, physiological opioid dependence, or acute opioid withdrawal, and it should not be used by someone with a known hypersensitivity to naltrexone or a product ingredient. Acute hepatitis, liver failure, or other significant liver disease requires careful clinical assessment, and symptoms such as persistent upper abdominal pain, dark urine, or yellowing of the skin or eyes require prompt medical attention. A person should use caution when driving or operating machinery until they know how the medicine affects them because dizziness or drowsiness can occur.

Because naltrexone blocks opioid receptors, opioid-containing pain relievers, cough medicines, and antidiarrheal products may not work as expected. A person must not try to overcome the blockade by taking larger opioid doses, as doing so can cause life-threatening poisoning or overdose. Naltrexone can also complicate pain management during surgery or an emergency, so carrying a medication note or medical alert is a useful precaution. Sensitivity to opioids may be increased after naltrexone is stopped or near the end of a dosing interval, creating an additional overdose risk if opioid use resumes. Liver function testing may be appropriate before or during treatment based on the person's dose, history, symptoms, and other risk factors. Anyone who is pregnant or breastfeeding should discuss the benefits and risks with a prescriber before starting, and safety and effectiveness in children have not been established.

Store these capsules at 68°F to 77°F in their original, tightly closed container, away from light and moisture. When a package arrives, check the strength printed on the label against the 1.5 mg strength ordered, confirm that the capsule count matches the selected package size, and store the bottle promptly rather than leaving it somewhere warm or humid, such as a bathroom cabinet.
