How bad is doxycycline at staining adult teeth?

[Dennis S]

I’ve been prescribed it for rosacea. I know it can sometimes stain teeth.

Dennis,

I've been on it. No staining. Now, if you'd asked about tetracycline, I'd say it can definitely cause permanent staining of teeth. Doxycycline? Not in my experience. Check with your doctor or pharmacist and see what he/she has to say about it.
