Glaucoma Medication Causing My Eyebrow Loss?

I have been diagnosed with glaucoma. Treatment was started approx 10 months ago (eye drops), and has been altered because of some allergic reaction (red eyes). In the past three months, I have been losing an excessive amount of head hair, daily. Also my eyebrows and lashes are noticeably thinning. Can there be any relation to this loss with the medicine that is used to treat glaucoma?

There is no substitute to a good medical examination of your hair. I would start looking there. I know of no connection between glaucoma and head hair loss or eyebrow loss, but I would keep the medication off of the eyebrows. There is a glaucoma medication (bimatoprost) that was recently FDA approved to treat eyelash growth, and some expect that applying it to the scalp will regrow hair (I’ve not read enough about the medication and am not clear on it yet)… but I don’t know which medication you were using, so I can’t help much more.
