Xenical is taken orally three times a day, during or one hour after each fat containing meal. For better results, spread the daily consumption of fats, proteins and carbohydrates evenly between meals. If you skip a meal, skip the dose of Xenical as well.
The medication may impede the absorption of fat-soluble vitamins such as A, D, E, or K; therefore, it is recommended to combine it with a daily multivitamin supplement, taken 2 hours before or after Xenical. It may take a significant amount of time before you notice the first weigh management results.
