Melatonin Dosage Calculator

How to Calculate Melatonin Dosage

This calculator determines a safe melatonin dose based on indication, form type, and therapy duration, using these formulas:

Daily Dose (mg):

Daily Dose (mg/day) = Indication-Specific Maximum Dosage

Units Needed:

Tablets/Capsules or Strips = Daily Dose (mg) × Therapy Duration (days) / Strength (mg)

Liquid Volume (mL) = Daily Dose (mg) × Therapy Duration (days) × 25 (mL/mg)

Drops = Liquid Volume (mL) × 5 (drops/mL)

Spray Applications = Daily Dose (mg) × Therapy Duration (days) / 0.5 (mg/application)

Where:

Indication: Trouble Falling Asleep (0.3–5 mg), Jetlag Eastbound/Westbound (0.5–5 mg), Insomnia in Blind People (0.5 mg), Beta-Blockers Insomnia (2.5 mg), Endometriosis (10 mg).
Form Type: Tablets/Capsules (1, 3, 5, 10 mg), Liquid (1 mg/25 mL), Spray (0.5 mg/application), Strips (1, 3 mg).
Therapy Duration: User-entered number of days (default 25).

Dose is taken as specified (e.g., 1 hour before sleep, before/after flights).

Using the Melatonin Dosage Calculator

This tool estimates a melatonin dose based on indication, form type, and therapy duration. Select the indication (e.g., Trouble Falling Asleep), choose the drug type (Tablets/Capsules, Liquid, Spray, Strips), enter the therapy duration (default 25 days), and review the results for dosage, timing, and units needed.

Example: Trouble Falling Asleep, Tablets/Capsules, 30 days:

Therapy Duration: 30 days
Recommended Dosage: 0.3–5 mg daily
Timing: Taken 1 hour before sleep (🛌)
Number of tablets needed for 30 days with maximum dose (5 mg):
• 1 mg tablets: 150 tablets
• 3 mg tablets: 50 tablets
• 5 mg tablets: 30 tablets

Consult a healthcare provider before administering.
