Orlistat is a well-known medication that seems to be effective in causing weight loss.  It can be bought as a prescription medication or as an over-the-counter medication. However, there have been some concerns about the adverse effects and drug interaction it may produce.

According to the Doses, Uses and Warnings, published online by Medscape, patients taking this medication may be in the danger of developing deficiency in fat soluble vitamins namely Vitamin A, D, E and K.  As stated in this source, fat-soluble vitamin deficiency is brought about by the inhibition of orlistat to the enzyme responsible for the gastrointestinal absorption of the said vitamins.  In fact, in a study mentioned in the article published by Dose, Uses and Warnings, it was noted that patients taking Orlistat has a 30 percent reduction in the overall absorption of beta-carotene and 60 percent decrease in the Vitamin E absorption.  In another study mentioned in the said article, it has been observed that patients who took this weight loss medication have a significantly reduced Vitamin D levels in the body compared to the baseline values they had before they started taking this medication.

And so, because of this danger in the development of fat-soluble vitamin deficiency, it is strongly recommended that multivitamin supplements must be taken about two hours or more before the intake of Orlistat to prevent the said vitamin deficiency.

If you are one of those people who are planning to take this medication for your weight loss regimen, it is strongly advised that you talk with your family physician first.  An expert advice is necessary before you start or discontinue any medication.
