Common Over-the-Counter Pain Relievers
Most everyday aches can be managed with nonprescription medicines, but they work in different ways and carry different risks. Always follow the label and ask a pharmacist if you're unsure which is right for you.
Acetaminophen
Tylenol and store brands
Good for: headaches, fever, general aches
Watch out: too much can cause serious liver damage. It's found in many cold and flu combos, so check labels to avoid doubling up.
NSAIDs
Ibuprofen, naproxen, aspirin
Good for: pain with swelling, like sprains, cramps, and arthritis
Watch out: can irritate the stomach and affect the kidneys and blood pressure. Take with food and avoid long-term use without medical advice.
Topical Pain Relievers
Creams, gels, and patches
Good for: sore muscles and joints in a specific area
Watch out: don't use on broken skin or with a heating pad, and wash hands after applying.
Using Antibiotics Wisely
Antibiotics are lifesaving when they're needed, but overuse helps bacteria become resistant, making future infections harder to treat.
- ✗They don't work on viruses like colds, flu, or most sore throats
- ✓Take them exactly as prescribed, for as long as your doctor says
- ✗Never share antibiotics or take leftovers from a past illness
- ✓Ask whether your illness is bacterial or viral
- ✓Report side effects like rash, severe diarrhea, or swelling right away
Everyday Medication Safety
Simple habits that prevent most medication mistakes.
- ✓Keep an up-to-date list of everything you take, including vitamins and supplements
- ✓Use one pharmacy so it can check for interactions
- ✓Use the measuring device that comes with liquid medicines, not kitchen spoons
- ✓Store medicines in a cool, dry place, out of reach of children and pets
- ✓Ask before mixing medicines with alcohol
- ✓Use a pill organizer or phone reminders to stay on schedule
