Does anybody know any connection between Doxycycline /Periostat/ and ophthalmic migraine,eye floaters and photophobia/light sensitivity/.
I developed photophobia about two months ago.Now I can see more floaters which are more sensitive to light and sometimes move very fast in all directions inside my both eyes.
Since January I was taking Periostat for three months for my gum disorder.After that I had to stop taking this drug because of side effects. My eyes were checked by MD/retina,sight etc./-everything seems to be OK except these fast moving-bright /like gel/ floaters.They are more visible and annoying now.
It happens almost every day-especially when I look at brighter spots-like:white posters,LCD screens,glare or flashing objects.

Photosensitivity is one of the rare side effects of doxycycline. Other symptoms of side effects include headache and visual disturbance, which may indicate benign intracranial hypertension.

But since you have discontinued the drug almost a month ago, side effects due to doxycycline probably should subside.

Better consult a specialist to r/o the possibility of potentially serious underlying problems.

just curious why doxycycline was prescribed. I had to take it to prevent infection with anthrax.

My dentist prescribed Periostat for Periodontitis /Periostat which is Doxycycline/-/20mg/ tablet twice a day.
First time I was taking Periostat around two years ago for about sixty days and I developed gums infection because of strange-unusual side effect/my gums were badly swollen/.
After that I right away discontinued my Periostat regime and my gums were good again-probably after one week or so.
This time it seems to be much worse.
After 3 months of taking Periostat I developed light sensitivity,eye redness and lots of gel-like floaters which work like magnifying glass and are getting very annoying and scary.
It's been with me for last eight weeks.
Any help or ideas MD's please ?
