When to take, or is it safe Vitamin A while on Doxycycline for MGD

[jaiya1985]

Hi,

https://www.drugs.com/drug-interactions/doxycycline-with-vitamin-a-940-0-2303-0.html
Drugs.com says

"Using vitamin A together with doxycycline may increase the risk of a rare, but potentially serious, condition called pseudotumour cerebri caused by increased pressure in the brain. In some cases, this can lead to permanent vision loss"

1. What is the safe dose of vitamin A that I can take while on Doxycycline? I am currently taking 10,000 IUs (3000mcg) of vitamin A for my dry eyes. It helps with my lack of tear production situation.

2. When should I take Vitamin A supplements while on Doxycycline?

3. Can I take Vitamin A, 3 hours after taking doxycycline? If yes, can I take 3000mcg of Vitamin A, OR should I lower it to the safe Vitamin A amount in question 1.

OR

4. can I not take vitamin A at all until I finish taking the whole doxycycline course?

2 I can't answer this, if it is answerable it needs to come from your personal physician
