Key differences
Ozempic belongs to Diabetes Treatment while Aygestin belongs to Women's Sexual Health. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Ozempic: After subcutaneous injection, semaglutide is absorbed slowly and binds to the GLP-1 receptor in pancreatic beta cells, alpha cells, central nervous system and gut. Aygestin: Norethindrone binds to progesterone receptors and exerts progestational effects: thickening cervical mucus, suppressing the LH surge, thinning the endometrium and reducing endometrial implant activity in endometriosis.
When Ozempic is preferred
The medication is indicated in adults with type 2 diabetes mellitus, alone or in combination with other antidiabetic agents, to improve glycaemic control.
When Aygestin is preferred
Aygestin is approved for endometriosis-associated pain, abnormal uterine bleeding due to hormonal imbalance, and secondary amenorrhoea.
