Coughing up blood
Cough suppressants may help if this condition is due to throat irritation from violent coughing. However, cough suppressants may lead airway obstruction in some cases. Always check with your doctor first.
It is very important to note how long you cough up blood. You should also keep track of the following:
Consult the doctor if
- How much blood is mixed with the mucus
- Symptoms such as lightheadedness, dizziness, or thirst, which might indicate a severe amount of blood loss
- Other symptoms such as fever, chest pain, shortness of breath, and blood in the urine
If there is any unexplained coughing up of blood, call an ambulance or go to the nearest emergency department. This is very important if your cough produces large volumes of blood (more than a few teaspoons), or if it is accompanied by severe shortness of breath, lightheadedness, or dizziness.
