Contraindications / Warnings / Precautions

Do not use in patients with known hypersensitivity to tramadol or to any of the excipients.

Do not use in pregnant or lactating animals.

Simultaneous administration with deprenyl or with psychotropic drugs such as serotonin reuptake inhibitors, tricyclic antidepressants or monoamine oxidase inhibitors may increase seizure threshold. If administered in combination with drugs which are enzymatic inductors, such as carbamazepine, phenobarbital, phenytoin or rifampin, the dose of tramadol should be increased.

Inhibitors of isoenzyme CYP 2D such as amiodarone, cimetidine, clomipramine and haloperidol may decrease the metabolism of tramadol thus reducing the levels of metabolite M1 and, consequently, the analgesic effectiveness, and increasing the appearance of adverse reactions.

Tramadol is contraindicated in patients with respiratory depression, acute obstructive pulmonary disease, uncontrolled epilepsy and acute renal and/or hepatic failure. In patients with liver cirrhosis, the dosing interval shall be reduced. In patients with chronic renal and/or hepatic failure the dosing interval shall be increased.

Tramadol can cause miosis which may mask the presence or exacerbation of clinical features of intracranial hypertension.

Adverse reactions are rare. The most frequent ones include: gastrointestinal malaise such as nausea, vomiting, constipation or diarrhea. In connection with the nervous system, nervousness, anxiety, agitation, shaking, spasticity, euphoria, deterioration in coordination, somnolence or insomnia may be experienced. In case of apparent sedation or strange behavior, the dose should be reduced.

Side effects:
It is recommended to gradually increase the dose within 3 days, in order to reduce the presence of nausea and vomiting. The administration of an antiemetic drug during the first days of treatment can also be beneficial. Observe normal aseptic precautions.
In case of overdose, somnolence, dizziness, bradycardia, dyspnea, miosis, sensory disorders and seizures may be experienced. In this cases, gastric lavage should be performed (do not induce vomiting since it may lead to aspiration pneumonia), administer naloxone (0.02 - 0.1 mg/kg body weight IM or IV, by administering ¼ of the calculated dose every 3 -4 minutes until the desired effect is reached) and also provide parenteral hydration, oxygen therapy and ventilatory support. In case of seizure, indicate diazepam.
