From the Guidelines

Hormone replacement therapy products similar to Estalis include several combination estrogen-progestogen formulations, such as Activelle/Activella, Kliovance, CombiPatch, and Climara Pro. These medications all provide continuous combined therapy with both estrogen and progestogen components, though they differ slightly in their specific hormones, dosages, and delivery methods. Some are available as patches (like Estalis and CombiPatch), while others come in tablet form (like Activelle). The purpose of these combination products is to relieve menopausal symptoms while protecting the endometrium from hyperplasia that can occur with estrogen-only therapy. The estrogen component (estradiol) addresses symptoms like hot flashes, night sweats, and vaginal dryness, while the progestogen component (norethisterone or similar) prevents excessive endometrial growth. When considering alternatives to Estalis, it's essential to maintain the same therapeutic approach of combined hormone therapy, though individual responses may vary between products due to slight differences in hormone types, doses, and delivery systems 1. Key considerations include the specific hormones used, their dosages, and the method of delivery, as these can influence the efficacy and safety of the treatment. For example, the combination of estradiol and norethindrone acetate in Activelle/Activella or the combination of estradiol and levonorgestrel in Climara Pro may offer similar benefits to Estalis but with potentially different side effect profiles. Ultimately, the choice of an alternative to Estalis should be based on a thorough discussion between the patient and her clinician, considering her individual risk factors, symptoms, and preferences 1.
