Drug Interaction Classification
These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
– 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 interaction information available.
Interactions between your drugs
CarBAMazepine may reduce the blood levels of codeine, which may make codeine less effective in treating your condition. Additionally, if you have been receiving treatment with codeine, adding carBAMazepine may cause you to experience unpleasant withdrawal symptoms such as excessive sweating, chills, flushing, restlessness, irritability, anxiety, tremor, rapid heartbeat, and nausea. On the other hand, if you have been receiving both medications, suddenly discontinuing carBAMazepine may increase the blood levels of codeine, which could increase or prolong its adverse effects. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and food interactions
You should preferably avoid the regular consumption of grapefruits and grapefruit juice while taking carBAMazepine. This can cause carBAMazepine levels to increase. You should report signs of carBAMazepine side effects such as nausea, visual disturbances, dizziness, or muscle weakness to your doctor. You should avoid or limit the use of alcohol while being treated with carBAMazepine. Alcohol can increase the nervous system side effects of carBAMazepine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. Talk to your doctor or pharmacist if you have any questions or concerns.
