Take the drug on an empty stomach.
Take the drug along with a meal.
Take the drug along with milk or fruit juice.

The Correct Answer is A

B. Take the drug along with a meal is incorrect as it can reduce the absorption of tetracycline.
C. Take the drug along with milk or fruit juice is incorrect because calcium and magnesium can bind to tetracycline, decreasing its effectiveness.
