  • Medicines can help decrease pain or prevent bacterial infections. Ask your healthcare provider how to take prescription pain medicine safely.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Home care:

  • Avoid blowing your nose too hard. Blow your nose gently or use a soft rubber suction bulb.
  • Drink plenty of liquids. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you. Limit the amount of caffeine you drink.
  • Rinse your nose with salt water. This may help loosen your thick mucous so that it comes out more easily when you blow your nose. Ask your healthcare provider for more information on how to prepare and do nasal washings.
  • Use a cool-mist vaporizer or humidifier to add moisture to the air. This helps thin your nasal discharge and prevent colds. Wash the humidifier each day with soap and warm water to keep it free of germs.
  • Wash your hands frequently. Wash your hands after you come into contact with a person who has a cold. Germ-killing hand lotion or gel may be used to clean your hands when there is no water available.

Nasal packing:

Ask your healthcare provider how long the nasal packing will stay inside your nose. If it needs to be removed and replaced at home, ask your healthcare provider how to properly do this.

Contact your healthcare provider if:

  • You have a fever.
  • You have chills, a cough, or feel weak and achy.
  • You have bruises or swelling around your nose or eyes.
  • You have nausea or vomiting.
  • Blood soaks through your nasal packing.
  • Your skin is itchy, swollen, or has a rash.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You have a stiff neck or eye pain, especially when you look directly at light.
  • You have a severe headache that does not go away even after you take pain medicine.
  • You have clear fluid coming from your nose.
  • You have pus or a foul-smelling odor coming from your nose.
  • You have trouble breathing, seeing, talking, or thinking clearly.
  • Your face is getting numb.
  • Your symptoms come back or become worse.
