Xenical Overdose

Taking too much of a weight loss medication can often cause dangerous side effects. With Xenical, overdose effects don't appear to be as serious. In clinical studies, taking large doses of the drug did not cause problems (other than the usual side effects). Regardless, if you believe that you have taken a Xenical overdose, you should still contact your healthcare provider.

 

Xenical Overdose: An Introduction

Xenical® (orlistat) is a prescription medication approved as a weight loss aid. The effects of a Xenical overdose will vary depending on a number of factors, including the Xenical dosage and whether it is taken with any food, medicines, alcohol, or street drugs.
 
If you happen to overdose on Xenical, seek immediate medical attention.
 

Symptoms of a Xenical Overdose

Many diet and weight loss products (especially stimulants) can be dangerous if you take too much. However, this does not seem to be the case with Xenical. In one study, people took large doses of orlistat (the active ingredient of Xenical) for up to 15 days without experiencing any problems other than the usual Xenical side effects.
 
If you take too much Xenical, it is reasonable to expect the usual intestinal-related Xenical side effects, although they may be more severe (particularly if you eat a high-fat meal while taking too much Xenical). It is probably a good idea to avoid eating fat for a few days, as this can help decrease the side effects.
 

Treatment for a Xenical Overdose

It is not known how best to treat a Xenical overdose. Therefore, treatment (if necessary) will consist of supportive care. This type of care consists of treating the symptoms that occur as a result of the overdose. For instance, if an overdose caused dehydration due to severe diarrhea, then supportive treatment would include electrolytes and fluids to treat the dehydration.
 
It is important that you seek prompt medical attention if you believe that you may have overdosed on Xenical.
