If no serious side effects occur, it is recommended to keep taking orlistat. Orlistat is an oral weight loss medication. Orlistat is mainly used for the treatment of overweight as well as weight loss in adults. Orlistat is used for weight loss and fat reduction by inhibiting lipase activity in the intestine, thus inhibiting the hydrolysis of fat in the intestine and reducing the absorption of fat in the intestine through dietary intake. The inhibition of lipase in the intestinal tract can be maintained for 24-48 hours with oral orlistat, but after 48-72 hours orlistat is metabolized by the body and loses its fat inhibition and absorption effect. If no serious, intolerable toxic side effects occur, it is recommended that orlistat be taken consistently.
