HRT is one of the most studied interventions in women's medicine — and it's also a serious medical therapy. It's not appropriate for everyone, and licensed providers carefully evaluate each candidate before prescribing.
The goal of this article isn't to talk anyone out of considering HRT — it's to make the clinical decision process transparent so you can have a more informed conversation with your provider.
Conditions that may rule out HRT
- Active cancer or undergoing cancer treatment
- History of estrogen-sensitive cancers (breast, endometrial) — case-by-case
- History of blood clots (deep vein thrombosis, pulmonary embolism)
- Arterial thromboembolic disease — heart attack or stroke
- Severe liver impairment
- Undiagnosed abnormal vaginal bleeding
- Pregnancy or breastfeeding
- Over 65 years of age (case-by-case, with more careful evaluation)
Other factors providers consider
This list is not comprehensive. Additional medical conditions, current medications, family history, and individual risk factors may affect whether HRT — and which delivery method — is appropriate for you. For example, transdermal delivery may be considered when oral would not, or lower-dose local therapy may be an option when systemic isn't.
Eligibility is determined by a licensed provider based on a full medical evaluation. If HRT isn't the right fit, you'll be told so during your assessment so you can pursue care that is.

What tends to help
Most side effects are mild and resolve as your body adjusts over the first 4–8 weeks. If symptoms persist, dose adjustments, changing delivery method (oral to transdermal, or vice versa), or timing changes often resolve them.
Persistent or concerning symptoms should always be discussed with your provider — especially unexpected bleeding, severe headache, chest pain, or leg swelling, which warrant immediate evaluation.
