Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

What should I do if the prescription label falls off my medicine bottle?

Bring the bottle back to your pharmacy right away. Do not guess what the medicine is or how to take it. The pharmacist can verify the prescription in their computer system and print a new, safe label for your bottle.

Can I take medicine after its expiration date if it looks normal?

No, you should never take expired medicine. Even if the pills look fine, chemical breakdown can make the drug ineffective or potentially harmful over time. Safely dispose of expired medicines and get a fresh supply.

What does "generic name" mean on a medicine label?

The generic name is the official scientific name of the active chemical ingredient inside the medicine. Generic medicines work the exact same way as expensive brand-name drugs but usually cost greatly less.

Why do some prescription labels require me to take medicine with food?

Some medicines irritate your stomach lining or absorb much better when food is present in your digestive tract. Taking them with a meal or snack prevents stomach upset and helps your body process the drug correctly.

How can I find out if my new prescription interacts with my current vitamins?

Always share a complete list of your prescription drugs, over-the-counter products, and vitamins with your pharmacist. They can run a safety check to ensure your new medicine does not cause unwanted interactions with your current supplements.
