Example Calculations
Adult Acute Pain Example
Patient: 45-year-old adult with post-operative pain
Dosing: 50mg every 4-6 hours as needed
Daily total: 200mg (4 doses)
Maximum: 400mg/day
Adult Chronic Pain Example
Patient: 55-year-old with chronic back pain
Starting dose: 100mg once daily (ER tablet)
Titration: Increase by 100mg every 5 days
Maximum: 300mg/day
Elderly Patient Example
Patient: 80-year-old with arthritis pain
Starting dose: 25mg every 6 hours
Daily total: 100mg (reduced dosing)
Maximum: 200mg/day (half normal dose)

Major Drug Interactions
High Risk Combinations:
- • MAO inhibitors (risk of serotonin syndrome)

Understanding Tramadol Dosing
What is Tramadol?
Tramadol is a centrally-acting synthetic opioid analgesic with dual mechanisms of action. It provides pain relief through both opioid receptor binding and inhibition of serotonin and norepinephrine reuptake. It's classified as a Schedule IV controlled substance.
Unique Properties
- •Ceiling effect - higher doses may decrease effectiveness
- •Lower addiction potential than traditional opioids
- •10 times less potent than morphine
- •Onset of action: 15-30 minutes
Dosing Guidelines
Acute Pain (Adults 17-75 years)
- • Starting dose: 50mg every 4-6 hours
- • May increase to 100mg per dose
- • Maximum: 400mg/day
Chronic Pain (Adults)
- • Starting dose: 100mg once daily (ER)
- • Increase by 100mg every 5 days
- • Maximum: 300mg/day
Special Populations
- • Elderly (>75 years): Reduce dose by 50%
- • Renal impairment: Reduce dose and extend intervals
- • Pediatric: 1-2 mg/kg/dose (where permitted)
Available Formulations
Immediate Release
For acute pain management
- • 50mg tablets (most common)
- • Onset: 30-60 minutes
- • Duration: 4-6 hours
Extended Release
For chronic pain management
- • 100, 150, 200, 300mg tablets
- • Once daily dosing
- • Duration: 12-24 hours
Oral Solution
For pediatric use (where permitted)
- • 100mg/mL concentration
- • Easier dosing adjustments
- • Faster absorption

This calculator is for educational and informational purposes only. Tramadol is a controlled substance that requires proper medical evaluation, prescription, and monitoring. This tool should never replace professional medical judgment or clinical assessment.
Healthcare providers must consider individual patient factors including medical history, concurrent medications, renal/hepatic function, and risk factors for abuse before prescribing tramadol. Patients should never self-medicate or alter prescribed dosages.
Improper use of tramadol can result in addiction, overdose, respiratory depression, seizures, or death. Always consult qualified healthcare professionals for pain management.
