Blood that comes up with a cough often looks bubbly because it is mixed with air and mucus. It is usually bright red, although it may be rust-colored. Sometimes the mucus may only contain streaks of blood.

Cough suppressants may help if this condition is due to throat irritation from violent coughing. However, cough suppressants may lead to airway blockages in some cases. Always check with your doctor before using them.

It is very important to note how long you cough up blood, and how much blood is mixed with the mucus. Contact your doctor any time you cough up blood, even if you do not have any other symptoms.
