A member asked:
Just started 100mg twice daily of doxycycline for tick bite/rash. how long before side effects start? if any? severe nausea?
A doctor has provided 1 answer
May not get any: Not everyone has side effects to medication. Normally it begins in the first 24 hours you may get stomach upset so take the pills with small meal and plenty of water. Avoid direct sun exposure, no tanning until you are off the medication a good 2 weeks.
