How can this medicine affect other medicines?

Carbamazepine can interact with many medicines and the dose of carbamazepine or the interacting medicine may need to be altered as a result. It is important to tell your doctor what medicines you are taking, including herbal medicines and those bought without a prescription, before you start carbamazepine. Likewise, once you are taking carbamazepine it is important to check with your doctor or pharmacist before you start taking any new medicines, or stop taking any existing medicines. Carbamazepine blood levels may be increased by: - acetazolamide - azole antifungals, eg fluconazole, ketoconazole - cimetidine - danazol - dextropropoxyphene - diltiazem - fluoxetine - fluvoxamine - haloperidol - isoniazid - macrolide antibiotics, eg erythromycin, clarithromycin - nefazadone - nicotinamide - protease inhibitors (HIV), eg ritonavir - terfenadine - verapamil - viloxazine. Sodium valproate and lamotrigine may increase the rate that carbamazepine is converted to another active form in the body. This can result in an increase in carbamazepine side effects. Carbamazepine blood levels may be decreased by: - chemotherapy medicines, eg cisplatin, doxorubicin - isotretinoin - phenytoin - phenobarbitone - primidone - theophylline - rifampicin - sodium valproate - St John's wort. Carbamazepine may decrease the blood levels and effectiveness of the following: - benzodiazepines, eg alprazolam, clonazepam, diazepam, midazolam - calcium channel blockers, eg felodipine, nimodipine - corticosteroids, eg dexamethasone, prednisolone - ciclosporin - clozapine - doxycycline - ethosuximide - gestrinone - haloperidol - itraconazole - lamotrigine - methadone - oestrogens - olanzapine - oxcarbazepine - paracetamol - primidone - progestogens - protease inhibitors (HIV), eg indinavir, saquinavir - risperidone - tricyclic antidepressants such as imipramine - theophylline - thyroid hormones - tiagabine - tibolone - topiramate - toremifene - tramadol - sodium valproate - warfarin. Carbamazepine may raise or lower blood levels of phenytoin. Carbamazepine should not be taken with monoamine oxidase inhibitor antidepressants (MAOIs). At least two weeks should pass after stopping an MAOI before starting carbamazepine. There may be a decrease in blood sodium levels if carbamazepine is taken with diuretics such as frusemide and hydrochlorothiazide. If carbamazepine is taken with lithium or haloperidol there may be an increase in brain and nervous system side effects, eg confusion, drowsiness, weakness, lethargy and tremor. If carbamazepine is taken with isoniazid there may be an increased risk of liver disorders.
