Expectorant

Expectorant is a type of medicine that helps bring up mucus and other material from the lungs, bronchi, and trachea. It is often used to treat coughs associated with illnesses like colds, flu, and bronchitis.

Mechanism of Action

An expectorant works by increasing the amount of water in the mucus, making it less sticky and easier to cough up. This helps clear the airways, making it easier to breathe. The most common expectorant used in over-the-counter medicines is guaifenesin.

Uses

Expectorants are used to treat coughs that are caused by a build-up of mucus in the lungs. They are often used in combination with other medicines, such as decongestants and pain relievers, to treat the symptoms of colds and flu.

Side Effects

Like all medicines, expectorants can have side effects. These can include nausea, vomiting, and stomach pain. If these side effects are severe or do not go away, it is important to contact a healthcare provider.

Precautions

Before using an expectorant, it is important to read the label and follow the directions. It is also important to drink plenty of fluids, as this can help the medicine work better. If symptoms do not improve after 7 days, or if they get worse, it is important to seek medical attention.
