Cold or Allergies? How to Tell the Difference

by Boulder Medical Center

If you’ve been sneezing, sniffling, or feeling congested, you may wonder whether you have a cold or allergies. Both can cause similar symptoms, but how you treat them depends on what’s behind your discomfort.

Understanding the difference can help you find relief faster and know when to visit urgent care or your local pharmacist for guidance.


Understanding Colds and Allergies

Colds are caused by viruses that spread from person to person. They usually start with a sore throat or runny nose, followed by congestion, sneezing, and sometimes a cough. Cold symptoms peak after a few days and typically clear up within one to two weeks.

Allergies occur when your immune system reacts to harmless substances like dust, pet dander, mold, or pollen. Common allergy symptoms include sneezing, itchy or watery eyes, and a stuffy or runny nose. Unlike colds, allergies don’t cause fever and can persist as long as you’re exposed to the allergen.

If your symptoms last longer than two weeks or seem to return regularly, allergies are more likely the cause.


How to Feel Better

Whether you’re dealing with a cold or allergies, simple steps can help you feel better:

  • Stay hydrated and get plenty of rest. Fluids help thin mucus and relieve congestion.
  • Use a humidifier to keep nasal passages comfortable.
  • Limit exposure to allergens by cleaning regularly and using air filters.

If your symptoms are severe, persistent, or interfering with daily life, consider visiting an urgent care or your primary care provider. These experts can help assess your symptoms, recommend treatment, and rule out infections that need further care.

You can also visit a pharmacy for guidance on over-the-counter medicines and allergy relief options.


When to Seek Medical Care

See a provider if you experience any of the following:

  • Difficulty breathing or rapid breathing
  • Symptoms lasting more than 10 days without improvement
  • Symptoms that improve but return and worsen
  • Fever lasting more than four days
  • Chronic health conditions that flare up
  • Any symptom that feels severe or concerning
