What are the results of taking doxycycline and exposure to sunlight?

As per https://www.drugs.com/doxycycline.html

"Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Doxycycline can make your skin more sensitive to sunlight and sunburn may result. Use a sunscreen (minimum SPF 15) and wear protective clothing if you must be out in the sun. Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking doxycycline."

I hope this helps.

Well it can make your skin more sensitive to the sun and burn more easily. If you are out in the sun for long periods of time, make sure to wear sunscreen.

I personally went on vacation and laid out for quite a while (I wore sunscreen), but didn't notice anything different. Then again, I don't burn easily.
