traMADol QUEtiapine

Applies to: tramadol and Seroquel (quetiapine)

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Concomitant use of opioids such as tramadol with other central nervous system (CNS) depressants such as quetiapine may result in hypotension, profound sedation, respiratory depression, coma, and death.

GENERALLY AVOID: There is some concern that quetiapine may have additive cardiovascular effects in combination with other drugs such as tramadol that are known to prolong the QT interval of the electrocardiogram. In clinical trials, quetiapine was not associated with a persistent increase in QT intervals, and there was no statistically significant difference between quetiapine and placebo in the proportions of patients experiencing potentially important changes in ECG parameters including QT, QTc, and PR intervals. However, QT prolongation and torsade de pointes have been reported during postmarketing use in cases of quetiapine overdose and in patients with risk factors such as underlying illness or concomitant use of drugs known to cause electrolyte imbalance or increase QT interval. The effect of tramadol on the QT interval was evaluated in a randomized, double-blind, 4-way crossover, placebo- and positive-controlled, multiple-dose ECG study of 62 healthy subjects. The maximum placebo-adjusted mean change from baseline in the Fridericia-corrected QT interval (QTcF) was 5.5 msec in the 400 mg/day treatment arm (100 mg every 6 hours on days 1 through 3 with a single 100 mg dose on day 4) and 6.5 msec in the 600 mg/day treatment arm (150 mg every 6 hours on days 1 through 3 with a single 150 mg dose on day 4), both occurring at the 8-hour time point. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). The extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).

MANAGEMENT: The use of tramadol in conjunction with quetiapine should generally be avoided unless alternative treatment options are inadequate. If coadministration is necessary, the dosage and duration of each drug should be limited to the minimum required to achieve desired clinical effect. Patients should be monitored closely for signs and symptoms of respiratory depression and sedation, and advised to avoid driving or operating hazardous machinery until they know how these medications affect them. Particular care should be exercised in patients suspected to be at an increased risk of torsade de pointes. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Moderate

traMADol food

Applies to: tramadol

Alcohol can increase the nervous system side effects of traMADol such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with traMADol. Do not use more than the recommended dose of traMADol, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Drug Interaction Classification

The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.

Do not stop taking any medications without consulting your healthcare provider.
