- Feeling dizzy or faint, or breathing faster than usual

Contact your healthcare provider if:

Medicines:
You may need any of the following:
- Medicine may be given to reduce the amount of acid your stomach produces. This may help if your melena is caused by an ulcer. You may also need medicine to prevent blood flow to an injury or tear.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider 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.
Manage or prevent melena:
- Do not take NSAIDs or aspirin. These medicines can cause gastrointestinal bleeding. Talk to your healthcare provider about other pain medicines that are safe for you to take.
- Do not smoke. Nicotine can damage blood vessels. Talk to your healthcare provider if you need help quitting. E-cigarettes or smokeless tobacco still contain nicotine. Ask your healthcare provider for information before you use these products.
- Do not drink alcohol or caffeine. Alcohol and caffeine can irritate your stomach. The lining of your stomach or intestine may also be damaged. Talk to your healthcare provider if you need help to quit drinking alcohol.
- Eat a variety of healthy foods. Healthy foods include fruits, vegetables, low-fat dairy products, lean meats, fish, and legumes such as lentils. Healthy foods can help you heal and improve your energy.
- Drink extra liquids as directed. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
