Tramadol oral tablets: adult dosing reference
Tramadol is a prescription opioid pain medicine. It is available in many countries, but is regulated differently and is not appropriate for every patient or every type of pain. The exact regimen must be prescribed after considering the pain cause, age, kidney/liver function, and other medicines.
| Form | Usual adult dose | How often / time of day | With food? | Total duration |
|---|---|---|---|---|
| Immediate-release (IR) tablet/capsule | 50 mg initially. If needed, a clinician may prescribe 50-100 mg per dose. | Usually every 4-6 hours only when needed for pain. If scheduled every 6 hours: morning, midday, evening, bedtime. Do not exceed 400 mg in 24 hours unless a clinician specifically directs otherwise. | Can be taken before or after food. Take after food if it causes nausea. | No universal number of days. For acute pain, use the lowest effective dose for the shortest possible time, commonly only a few days, then reassess. Do not continue or refill without medical review. |
| Extended-release (ER/SR/CR) tablet or capsule | Usually 100 mg once daily when starting. Dose changes must be clinician-directed. | Once daily, at the same time each day, such as morning or night. Do not crush, split, chew, or dissolve. Maximum is commonly 300 mg/day. | Usually with or without food, but take it the same way every day according to the product leaflet. | Intended only for selected adults with persistent pain requiring continuous treatment. Not for “as-needed” use and not normally a first choice for short-term pain. |
Important dose adjustments
| Situation | Safer label-based approach |
|---|---|
| Age over 75 years | IR total daily dose should generally not exceed 300 mg/day. |
| Severe kidney impairment, creatinine clearance below 30 mL/min | IR dosing interval is generally extended to every 12 hours; maximum usually 200 mg/day. Avoid ER formulations. |
| Severe liver disease/cirrhosis | Typical IR adjustment is 50 mg every 12 hours. Avoid ER formulations. |
| Children | Do not use in children under 12 years. Do not use after tonsil/adenoid surgery in anyone under 18 years. |
Do not take tramadol without urgent medical review if you use
- Alcohol, sleeping pills, benzodiazepines such as alprazolam/diazepam/clonazepam, or other opioids. The combination can cause fatal slowed breathing.
- Antidepressants or medicines that raise serotonin, including SSRIs/SNRIs, MAO inhibitors, some migraine triptans, linezolid, or St John's wort. There is a risk of serotonin syndrome and seizures.
- Medicines for epilepsy, or if you have a history of seizures.
- Pregnancy or breastfeeding.
- A history of opioid addiction, severe breathing disease, head injury, or severe kidney/liver disease.
Seek emergency help immediately for extreme sleepiness, slow or difficult breathing, blue lips, fainting, confusion, seizure, severe agitation, fever with sweating/tremor, or facial swelling.
Common effects include nausea, dizziness, sleepiness, constipation, dry mouth, and headache. Do not drive, operate machinery, or drink alcohol until you know how it affects you. Tramadol can cause dependence and withdrawal, so it should not be stopped suddenly after regular use without prescriber guidance.
The product labeling confirms that ER tramadol is once daily, must be swallowed whole, and should not exceed 300 mg/day; it is unsuitable in severe renal or hepatic impairment. DailyMed prescribing information also notes that oral tramadol can be taken without regard to food. Mechanistically, it has weak opioid activity plus serotonin and norepinephrine reuptake inhibition (Goodman & Gilman's The Pharmacological Basis of Therapeutics, p. 370).
A recent systematic review found only a small average benefit for chronic pain and increased adverse effects, supporting short, cautious, individualized use rather than routine long-term treatment (BMJ Evidence-Based Medicine review, PMID 41057269).
