Colds, Coughs & Sinus Infections

Why antibiotics usually won't help — and what actually will.

Why no antibiotic?

Nearly all colds, sore throats, coughs, and early sinus infections are caused by viruses. Antibiotics only kill bacteria. Taking one for a virus does nothing for you — but it can cause diarrhea, rashes, and yeast infections, and it teaches bacteria to resist antibiotics when you truly need them later.

What actually helps

  • Rest and plenty of fluids.
  • Honey for cough (adults and children over age 1) — it beats most cough syrups in studies.
  • Saline (salt water) nasal rinse or spray for congestion.
  • Acetaminophen (Tylenol) or ibuprofen for fever, aches, and sore throat.
  • A humidifier at night; warm liquids like tea or soup.
  • Ask us before using decongestants if you have high blood pressure.

When antibiotics ARE needed

  • Strep throat confirmed by a test — not every sore throat.
  • Sinus symptoms lasting more than 10 days without improving, or that improve and then get worse again.
  • Some ear infections and pneumonia.

When should I call?

  • Fever over 100.4°F lasting more than 3–4 days.
  • Symptoms lasting more than 10 days, or getting worse after starting to improve.
  • Trouble swallowing liquids, ear pain, or shortness of breath with normal activity.
  • You have a weak immune system, or you are just not sure — call, we are happy to check.
