When to see a doctor

Call 911 now: chest pain that does not go away, or spreads to the arm, neck, jaw or back, with sweating or breathlessness.
Stop bimatoprost and see the doctor at once: eye pain, a new eye infection, or a sudden drop in vision.
Your doctor or dermatologist: brows that were full and then lost hair in a smooth patch or fast, or loss on the scalp, beard or lashes too. It may be alopecia areata.
A dermatologist soon: brows thinning while the front hairline or temples recede, or the sideburns or beard thin. It may be a scarring hair loss.
Your doctor: thin brows with tiredness, feeling cold, weight gain or dry skin, or with breathlessness and pale skin. Ask for thyroid and iron blood tests.
Your doctor: brows that itch, flake, scale or look red.
Your doctor: pulling out brow hairs you cannot stop, or eating hair.
The prescriber: brows that thinned after a new medicine. Do not stop it on your own.
Stop minoxidil and see a doctor: a racing heart, faintness or dizziness, sudden weight gain, or swollen hands or feet.

I am not a doctor. This is not medical advice. This is self-education. Every dose and strength on this page is the one a trial or a label used, quoted from it. It is not a prescription. Minoxidil and bimatoprost on the brows are off-label. Talk to a physician who has your history before any prescription medicine. Smooth patches, loss elsewhere, or a receding hairline with thin brows: see a doctor first.
