Zepbound
(generic name: tirzepatide) is a
weight management medication used in adults who are obese or those who are overweight and have at least one weight-related condition. It belongs to a class of drugs known as
dual incretin receptor agonists. This means it mimics two natural hormones,
GLP-1 (glucagon-like peptide-1) and
GIP (glucose-dependent insulinotropic polypeptide), that help
regulate appetite and food intake.
By acting on both receptors, Zepbound increases the feeling of fullness, reduces hunger, and slows down how quickly food moves through the stomach. This combination helps a person
eat less and lose weight. In addition to lowering appetite, Zepbound also helps reduce cravings for high-calorie foods, especially those high in sugar and fat.
Zepbound is available in a
multi-dose prefilled injection pen, taken once weekly. The medication is part of a broader treatment plan that includes a reduced-calorie diet and increased physical activity. It is not a form of insulin and should not be used in children under 18.
Pregnant women should not be using Zepbound unless this has been discussed with a healthcare provider, as it might harm the unborn baby or pose a risk of miscarriage. For this reason, women planning to become pregnant should use appropriate
birth control measures during the treatment and one month after taking the last dose of Zepbound. Zepbound may pass into breast milk, and mothers should consult with a doctor if already feeding or planning to feed an infant.
Usual dosage
Follow the prescribing doctor’s dosage instructions which are printed on the label of the box. Check with a doctor or pharmacist if there are any doubts regarding the proper dosage and treatment regimen.
