How to Calculate Tramadol Dosage

This calculator determines a safe tramadol dose based on age group, weight (for <17 years), kidney/liver function (17–75 years), and pain type, using these guidelines:

Daily Dosage (mg):

For <17 years: 1–2 mg/kg/day (e.g., 5–10 mg for 5 kg)

For 17–75 years, Acute Pain: 200–400 mg/day (50–100 mg, 4–6 times/day)

For 17–75 years, Chronic Pain: 100–300 mg/day (start at 100 mg/day, add 100 mg every 5 days)

For >75 years: Start at lowest possible dose, max 300 mg/day (immediate release)

For Kidney/Liver Insufficiency (CrCl < 30 mL/min or cirrhosis): 50 mg every 12 hours

Units Needed:

For Acute Pain: Immediate release tablets (50 mg) needed per day based on frequency

For Chronic Pain: Number of tablets = Desired daily dosage (mg) / Tablet strength (mg)

Where:

Age Group: Less than 17 years, 17–75 years, or Greater than 75 years.
Weight: Patient’s weight in kg (required for <17 years only).
Kidney/Liver Insufficiency: Yes (CrCl < 30 mL/min or cirrhosis) or No (for 17–75 years).
Dosage Type: Acute Pain (4–6 times/day) or Chronic Pain (desired daily dosage in mg or ug).
Frequency: 4, 5, or 6 times per day (for Acute Pain).
Tablet Strength: 100 mg, 150 mg, 200 mg, or 300 mg (for Chronic Pain).
Desired Daily Dosage: User-specified dose in mg or ug (for Chronic Pain).

Dose is given as specified, with warnings for kidney/liver issues, maximum limits, and consultation requirements.

Using the Tramadol Dosage Calculator

This tool estimates a tramadol dose based on age group, weight (if <17), kidney/liver function (if 17–75), and pain type. Select the age group, enter weight (for <17), select kidney/liver status (for 17–75), choose the dosage type (Acute or Chronic Pain), and provide additional details (frequency for Acute Pain, tablet strength, and desired dosage for Chronic Pain). Results show the recommended daily dosage, tablets needed, and maximum limits.

Example: Age Group 17–75, No Kidney/Liver Insufficiency, Acute Pain, 5x per day:

Dosage for Acute Pain:
Immediate release tablets (50 mg) needed per day: 5–8 💊
Total daily dose: 250–400 mg
Maximum dose: 400 mg/day
Recommended dosing: 50–100 mg, 4–6 times per day.

Consult a healthcare provider before administering.
