Rimonabant is a medicine from the group of drugs called cannabinoid receptor antagonists that works by affecting the receptors in the brain blocking food cravings. This medicine can be used in people with type 2 diabetes as well as those with abnormal levels of fat in the blood. The company manufacturing rimonabant – Sanofi-Aveniss – also claims their medicine prevents the risk of developing cardiovascular disease and aids in smoking cessation. In case you are currently taking or have been taken for a while any of the following drugs please report it to your doctor: nefazodone, clarithromycin, itraconazole, telithromycin, ritonavir, or ketoconazole. These medicines have been reported to intensify the effects of rimonabant, which can lead to undesired health effects. If you are going to start any new medication this fact should be also reported to your health care provider. Although your health care provider will do everything possible for you to benefit from the treatment, there are also some things you are supposed to do as well. One of them is watching for any serious side effects that occur in a small number of people taking rimonabant, such as emotional disorder, sleepiness, hiccups, anger, night sweats, panic symptoms, restlessness, and hallucinations.
