The best way to get rid of phlegm in the throat is drinking enough fluids to thin it out. Phlegm can be caused by post nasal drip, sinus infection, or a cold. When mucus production is caused by a bacterial infection, antibiotics are sometimes warranted. When the infection and resultant mucus has been alleviated, the phlegm will generally go away.
Phlegm in the throat tends to be thick and can cause constant throat clearing and sometimes coughing. Drinking plenty of water thins out the mucus, making it easier to cough up and expel. Similarly, medications that are known as expectorants can also help reduce phlegm because they also have the ability to thin out secretions and make them easier to get rid of. Drinking milk can promote phlegm production in the throat, and people who are prone to the condition might consider reducing their consumption.
Sinus conditions can cause post nasal drip and mucus in the throat as well. Antihistamine medications dry up secretions, not only in the nose but in the throat as well. Phlegm in the throat is often reduced after taking antihistamines; however, these drugs can cause drowsiness and dry mouth. In addition, taking antihistamines can cause urinary retention and nosebleeds. Some people notice that instead of feeling drowsy after taking antihistamines, they feel anxious and experience a rapid heartbeat.
Drinking tea and lemon can decrease phlegm in the throat, and help ease a sore throat as well. Honey added to tea can help soothe inflamed throat tissues by coating the throat, but can worsen the feeling of phlegm. People who experience acid reflux often feel like they have excess phlegm or mucus in their throats too. Taking an acid-reducing medication can decrease acid production and alleviate this sensation in the throat.
Sometimes, sleeping with a vaporizer in the bedroom can improve sinus conditions and post nasal drip, thereby eliminating mucus formation. Unless the vaporizer is meticulously cleaned in-between uses, bacteria can build up and contaminate the air with infection causing droplets. This can lead to a sinus or bacterial infection, which can promote mucus formation in the throat and lead to persistent coughing. Rarely, mucus in the throat can become so thick that it hinders breathing. In these cases, a medical professional needs to be notified to determine the cause, and implement a treatment plan to reduce symptoms.
