Chronic Cough Precautions
Cough medication precautions:
- A cough that produces mucus can aid healing by expelling infected material. Suppressing this type of cough may reduce your body's ability to fight off the infection.
- Cough medicines can cause sleepiness and interact with alcohol, sedatives, and some antidepressants.
- Cough medicines should be used with caution in those with asthma, heart disease, high blood pressure, and prostate enlargement.
- Cough suppressants can make you sleepy or dizzy. This is especially true with prescription cough medicines.
- Follow product package instructions.
- Those with chronic bronchitis, emphysema, or chronic obstructive pulmonary disease may need to cough frequently to clear mucus. Cough suppressants may make the illness worse.
