Thanks for using healthCare magic.
Doxycycline is an antibiotic with a photosensitive potential . There is a chance that you might react to sunlight . However , it does not warrant you from stopping your activities.
In fact , reducing exposure to sunlight is surely a good advice however it is very rare to see such reactions .
In place of doxycycline i can recommend you to use another antibiotic like Z pack ( Azithromycin
) three days a week pulse dose for a period of 6 to 8 weeks .
you can safely go for your vacation and put a heavy suncreen like Neutogena Sunscreen .
Thanks and Take Care
