Tetracycline and antacid should not be given together.

In the given order, tetracycline and antacid are given together. The antacid is in the aspirin. The tetracycline and antacid should not be used together because the presence of antacid will suppress the effectiveness of the tetracycline. This is because antacid contains chemical compounds such as sodium bicarbonate which can interact with the tetracycline.
