Formulations of LDN
LDN can be in either: Liquid, Capsules, Sublingual, Cream, Topical Lotion, Eye Drops or Tablets.
Oral Liquid formulation at 1mg/1ml is the most commonly used type of LDN. It is taken daily and dosed using a baby oral syringe.
Cost approx. $0.50 per dose.
In the USA, capsules or tablets in a variety of strengths are available from compounding pharmacies, but it is recommended that these be purchased only from compounders who have a significant level of experience formulating LDN.
Prices tend to range from $0.50-1.50 per dose.
Sublingual drops are designed for patients with problems taking medications orally, or for people who want to guarantee the fastest delivery of the drug into their bloodstream. A number of drops are placed under the tongue from a dropper bottle and dose is increased and decreased by the number of drops taken.
Cost about $1 a dose.
Cream & Topical Lotion
LDN Cream is most typically available in 0.5mg/ml and is available for application to the skin. This is helpful for children, or for patients allergic to colorings – flavorings or any excipients that may be found in other forms of LDN. It may be more expensive than oral forms.
The most common ophthalmic naltrexone dose is 0.2% and used for dry eye.
Tables are available from several compounding pharmacies in different strength forms.
