Correct answer: A — Take with plenty of water while upright and avoid lying down soon afterwards

Doxycycline can cause oesophageal irritation and should be taken with plenty of water while upright. Absorption can be reduced by iron, calcium and some antacids. The prescribed course should be completed unless advised otherwise. Photosensitivity counselling may also be relevant.
