How often do I take LDN?

You will take LDN daily at bedtime (between 9pm and 2am). To start, you will take 1 capsule (1.5mg) and, over time, will slowly ramp up to the prescribed dose (4.5mg is the most common).

How can I monitor my response to LDN?

In the short term, patients report an improvement or reduction of symptoms related to inflammation and rampant oxidative stress, such as joint pain, back pain, fatigue, weight gain, and more.

What form of LDN will I receive?

AgelessRx provides 1.5mg and 4.5mg in capsule form with sucrose as the standard filler. 

If you are taking LDN for the first time, you will begin at 1.5mg per day and slowly work up to the prescribed dose (commonly 4.5mg) over a 20-day period.


During the first three to five days of taking LDN, you may experience mild to moderate levels of the above side effects. Side effects typically diminish on their own by day five. To reduce the risk of side effects, start with a 1 capsule (1.5mg) for the first two weeks with a gradual increase to the 4.5mg dose.

If you are on thyroid medication, you may need to monitor your thyroid levels more closely as you start LDN. If you develop symptoms of hyperthyroidism while taking LDN, such as heart racing, increased anxiety, restlessness, or trouble sleeping, please stop LDN and talk to your doctor who prescribes your thyroid medication.

Note: Please stop taking any dosage of Naltrexone a minimum of 48-hours before any surgical procedure or medical diagnostic requiring sedation, such as surgery or a colonoscopy. If you are unsure, please ask your doctor ordering the test or procedure. Additionally, Naltrexone cannot be taken in conjunction with opioids/painkillers. If you need to stop taking Naltrexone for a surgery, and accompanying pain killers are prescribed, you may resume LDN only 48-hours after you take your last painkiller.
