may include any of the following:

  • Medicines may be given to fight a bacterial infection or to control a cough. You may also need medicine to slow or stop the bleeding.
  • 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.
  • A saline rinse of your nose and throat may help decrease or stop the bleeding.
  • Bronchial artery embolization is a procedure to inject medicine into your damaged blood vessel. The medicine will help stop the bleeding.
  • Surgery may be needed to help stop severe bleeding if other treatments do not work. Surgery may also be done to look for and correct other problems with your airway.

Follow up with your healthcare provider in 2 days or as directed:

You may need frequent visits to monitor your condition and prevent further blood loss. Write down your questions so you remember to ask them during your visits.

Use caution with medicines:

Certain medicines, such as NSAIDs, increase your risk for bleeding. Herbal supplements also increase your risk. Examples of herbal supplements are garlic, gingko, and ginseng. Ask your healthcare provider before you take any over-the-counter medicines.

Do not smoke, and do not go to smoky areas:

Smoke may worsen your hemoptysis. Nicotine and other chemicals in cigarettes and cigars can also cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
