“I may need to take an antacid to protect my stomach.”
“I will need to tell my doctor right away if I suspect I am pregnant.”
“I need to wear sunscreen at all times.”
“I cannot take this medicine with any dairy products.”
Number 1 is correct.
Tetracycline is an antibiotic prescribed for many bacterial infections. Patients should be instructed that this medication should be avoided in pregnancy, can cause photosensitivity, and cannot be taken with dairy products or other sources of calcium. Aluminum, iron, and zinc deactivate the medication, and tetracycline should not be taken with sources of these minerals, such as antacids.
