Triheptanoin Dosage

Medically reviewed by Drugs.com. Last updated on Feb 26, 2025.

Usual Adult Dose for Functional Gastric Disorder

Recommended total daily dose (mL) = patients DCI (kcal) x target % dose of DCI / 8.3 kcal/mL

• Round to nearest whole number
• Divide total daily dose into at least 4 approximately equal individual doses

Dose Initiation/Titration:

Patients not currently taking a medium chain triglyceride (MCT) product:

• Initiate at approximately 10% DCI divided into at least 4 individual doses.
• Increase to recommended total daily dose over 2 to 3 weeks.

Patients switching from another MCT product:

• Discontinue previous MCT before therapy initiation.
• Initiate at last tolerated MCT dose divided into at least 4 individual doses.
• Increase total daily dosage by approximately 5% DCI every 2 to 3 days until target dosage is achieved.

Comments:

• Assess metabolic requirements by determining daily caloric intake (DCI) prior to dose calculations.
• Recommended target is 35% of DCI.
• Caloric value of this product is 8.3 kcal/mL.

Use: As a source of calories and fatty acid in patients with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD).
