The effect of diet pills varies from person to person. Some people may lose weight quickly when they take diet pills, but if they don't change their eating habits and lifestyle, they will easily rebound once they stop taking them. Celecoxib is a prescription drug containing moxifloxacin, which is mainly used to treat obesity, but it also has side effects and risks and needs to be used under the guidance of a doctor. I suggest you take a healthy way to lose weight, such as improving diet and increasing exercise. And keep good living habits.
