It is advisable to consult a doctor before taking Rimonabant and adhere to the prescribed dosage to attain the expected results. Rimonabant should not be taken by pregnant woman since it may cause birth defects in an unborn baby. Rimonabant should not also be used by lactating mothers. Though not clinically proved, there is possibility that this diet pill may be passed into breast milk. Rimonabant is metabolized by the liver, so it is recommended that patients with moderate hepatic impairment should consult their healthcare provider before using the drug.

As your body adjusts to Rimonabant, you may experience some of the reported side effects like anxiety, disorientation, insomnia, nausea, headache, hallucinations, hypertension, heart and kidney damage, palpitations, heart attack, strokes, psychosis, fatigue and hyperphagia (excessive eating beyond normal feeling of hunger), gastrointestinal discomfort and dizziness.

Rimonabant may also be found to be effective in assisting some smokers to quit smoking. Sanofi-Aventis is currently conducting studies to determine the possible value of Rimonabant in smoking-cessation therapy. The Studies with Rimonabant and Tobacco Use (STRATUS) Program involves more than 6,000 subjects. STRATUS is designed to explore two smoking-related therapies. First, to use Rimonabant directly to aid in smoking cessation. Second, to help prevent weight gain in former smokers. Initial results apparently suggest that Rimonabant is effective for both uses.
