Acomplia (rimonabant) is an anti-obesity drug that is available by prescription from your local pharmacy or can be purchased online without one. This is a CB1 cannabinoid receptor antagonist that works by affecting certain chemicals in your brain responsible for the feeling of extreme hunger. The following side effects are possible when you start taking Acomplia, although they are likely to go away on their own without any need for you to consult your health care provider: nausea, irritability, dry mouth, anxiety, nervousness, sleep disorders, depressions, anorexia, vomiting, diarrhea, and impaired memory. Liver problems, impaired kidney function and a history of epilepsy can make it impossible for you to enjoy the benefits of taking Acomplia, so it’s recommended to tell your doctor about the presence of any of these health conditions. An overdose of Acomplia is not expected to be lethal, but it can produce certain effects that you will need to notify your health care provider of. The following symptoms are possible: insomnia, euphoria, fatigue, and headache. Never take this medicine if you are pregnant or breastfeeding without talking to your doctor, as this drug has been reported to cause health problems in unborn and nursing babies.
