The document discusses Telogen effluvium (TE), a common cause of medication-induced hair loss, particularly linked to anticoagulants like heparin and warfarin, with hair loss onset reported 3 weeks to 3 months after starting the medication. Direct oral anticoagulants (DOACs) are also associated with alopecia, but more research is needed to confirm this. Certain antihypertensive medications, specifically angiotensin-converting enzyme inhibitors and β-blockers, have been reported to cause hair loss in rare cases, but these may not be directly related to TE. Minoxidil, another antihypertensive, can cause reversible hypertrichosis (excessive hair growth) and is used in the treatment of androgenetic alopecia. The document concludes that the development of diffuse nonscarring alopecia should prompt suspicion for TE and thorough investigation of medications initiated 1 to 6 months prior to the onset of clinically apparent alopecia.
