Avoiding Risks with Over the Counter Drugs
If you have questions about over-the-counter medications, talk to your pharmacist or doctor. You should always talk to one of the professionals before using an OTC medicine the first time, especially if you use other medicine.
Carefully read OTC medicine labels for ingredients, proper uses, directions, warnings, precautions, and expiration dates.
Tell your doctor if you regularly take OTC drugs or "organic or natural" substances. These may interfere with prescription drugs.
