Drug Induced Hair Loss

Drug Induced Hair Loss

A surprising number of drugs have been associated with hair loss. These drugs are listed in the tables below.

Certain classes of medications are known to cause hair loss like anti-coagulants (heparin and coumadin) with more than 10% of patients experiencing hair loss in a dose-dependent fashion.

Anti-thyroid drugs that induce a state of hypothyroidism may also cause acute hair loss, like iodine, propylthiouracil, and carbimazole.

Psychopharmacologic medications like lithium, valproate, carbamazepine, and tricyclic antidepressants have been implicated in acute hair loss.

Oral contraceptives can cause hair loss 2 to 3 months after discontinuing treatment, which may be similar to what happens with delayed anagen release in the postpartum setting.
