Dose adjustments
SPC §4.2, verbatim: 'In patients with renal and/or hepatic insufficiency the elimination of tramadol is delayed. In these patient's prolongation of the dosage intervals should be carefully considered according to the patient's requirements. In cases of severe renal and/or severe hepatic insufficiency Tramadol drops are not recommended.' No creatinine-clearance bands or numeric reduced doses are given anywhere in this bundle.

Side effects
- Very common (≥1/10), SPC §4.8: nausea; dizziness — 'The most commonly reported adverse reactions are nausea and dizziness, both occurring in more than 10 % of patients'
- Common (≥1/100 to <1/10): headache, drowsiness, somnolence; constipation, dry mouth, vomiting, dyspepsia, abdominal pain; sweating; fatigue, asthenia, malaise; menopausal symptoms
- Uncommon (≥1/1000 to <1/100): palpitation, tachycardia, postural hypotension or cardiovascular collapse; anorexia, retching, gastrointestinal irritation (a feeling of pressure in the stomach, bloating), diarrhoea; dermal reactions (pruritus, rash, urticaria); drug withdrawal syndrome; toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome (SJS), cross reactivity with non-steroidal anti-inflammatory drugs, allergic reaction
- Rare (≥1/10 000 to <1/1000): epileptiform convulsions, involuntary muscle contractions, abnormal coordination, syncope, hypertonia, dysgeusia, paraesthesia, tremor, respiratory depression; delirium, hallucinations, confusion, sleep disturbance, anxiety, nightmares, changes in mood and activity, suicidal ideation; bradycardia, increase in blood pressure; dyspnoea, worsening of asthma; miosis, blurred vision; motorial weakness; micturition disorders (difficulty in passing urine, dysuria and urinary retention); menstrual disorders; weight loss, allergic reactions (e.g. dyspnoea, bronchospasm, wheezing, angioneurotic oedema), anaphylaxis
- Very rare (<1/10 000): elevated liver enzymes; panic attacks, severe anxiety, hallucinations, paraesthesias, tinnitus, CNS symptoms (confusion, delusions, depersonalization, derealization, paranoia)
- Not known: hypoglycaemia, hyponatraemia; serotonin syndrome; speech disorders; mydriasis; drug dependence — SPC §4.8: 'Repeated use of Tramadol oral drops can lead to drug dependence, even at therapeutic doses'
Monitoring
- SPC §4.2: 'During treatment, there should be frequent contact between the physician and the patient to evaluate the need for continued treatment, consider discontinuation and to adjust dosages if needed.'
- SPC §4.2: 'In absence of adequate pain control, the possibility of hyperalgesia, tolerance and progression of underlying disease should be considered (see section 4.4).'
- Respiratory depression — SPC §4.4: 'Care should be taken when treating patients with respiratory depression, or if concomitant CNS depressant drugs are being administered ... or if the recommended dosage is significantly exceeded ... as the possibility of respiratory depression cannot be excluded in these situations.'
- Seizures — SPC §4.4: 'Convulsions have been reported in patients receiving tramadol at the recommended dose levels. The risk may be increased when doses of tramadol hydrochloride exceed the recommended upper daily dose limit (400 mg).'
- Serotonin syndrome — SPC §4.4: 'If concomitant treatment with other serotonergic agents is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose escalations. Symptoms of serotonin syndrome may include mental status changes, autonomic instability, neuromuscular abnormalities and/or gastrointestinal symptoms.'
- Tolerance, dependence and opioid use disorder — SPC §4.4: 'Before initiating treatment with Tramadol oral drops and during the treatment, treatment goals and a discontinuation plan should be agreed with the patient (see section 4.2).'

Clinical monograph
How it works
It is a weak mu-opioid receptor agonist that also inhibits reuptake of serotonin and noradrenaline, contributing to analgesia.
Prescribing in practice
- In older people use cautiously at reduced dose with extended intervals, as they are more susceptible to confusion, sedation, falls, hyponatraemia and constipation, and reduced renal function prolongs exposure.
- It lowers the seizure threshold and carries a serotonin-syndrome risk with serotonergic drugs such as SSRIs, SNRIs and certain antidepressants and triptans.
- Like other opioids it can cause dependence and respiratory depression, with additive risk alongside benzodiazepines and other CNS depressants.
Monitoring
Monitor older patients for pain control, sedation, confusion, constipation and signs of serotonin toxicity, and review continued need.
Counselling the patient
- It can cause drowsiness and dizziness; take care with driving and standing up.
- Do not combine with alcohol or other sedatives, and report agitation, tremor or a fast heartbeat.
Evidence & guidelines
General prescribing guidance and the SPC highlight tramadol's seizure, serotonergic and CNS risks, supporting cautious reduced-dose use in older adults.
