Eucalyptus and coconut oil 

Eucalyptus essential oils are also recommended as a widely used remedy for treating and thinning phlegm buildup in the back of the throat. Healthcare professionals recommend them, but the FDA has not provided specific studies supporting essential oils to relieve mucus in the throat. 

Prescription medications

If you have certain health issues causing thick mucus in the back of the throat, your doctor might give you medicines to treat the main cause of your symptoms. For chronic lung conditions like cystic fibrosis, there are specific drugs to make your mucus thinner.

  1. Hypertonic Saline: One of the treatments is inhaling hypertonic saline through a nebulizer. It’s stronger than the saline you buy without a prescription, making it more effective. It increases salt in your air passages. It’s for people aged six and older but only brings temporary relief and may cause side effects like cough, sore throat, and chest tightness.
  1. Dornase-Alfa (Pulmozyme): It is another mucus-thinning medicine for cystic fibrosis. You inhale it through a nebulizer, and it’s suitable for people aged six and up. Side effects may include voice loss, rash, throat discomfort, fever, and dizziness.
  1. Other medications: Medications like antihistamines, nasal decongestants, expectorants, and antibiotics can also help greatly with the thick mucus in the throat by thinning the mucus as per your presenting symptoms and medical condition. Your healthcare provider will diagnose the cause and prescribe depending on your medical condition. You can also obtain the prescription for medications using online doctor services.

Is excess phlegm a sign of a serious condition?

Production of excess phlegm is also termed chronic mucus hypersecretion, where the natural production of mucus increases due to several reasons, some of which are: 

Consulting healthcare providers can help you with timely consultation and effective treatment plans to eliminate phlegm and debris. 

When should I worry about mucus in my throat?

Mucus exists in our body naturally with a very thin lining of our throat and several other integral body cavities as part of the body’s immune system. You should worry about mucus in your throat only when it gets extra thick, a sticky-like substance that hinders daily life dietary intake. 

The naturally present mucus gets thick only when: 

  • There is an infection underlying 
  • You have an allergy 
  • You have flared up asthma problem
  • Common cold 
  • You have chronic obstructive pulmonary disorder

These conditions need a consultation from your healthcare provider for timely diagnosis and effective treatment or via online doctor consultation.

When should I see a doctor?

Phlegm or mucus is the sticky substance present in the back of our throat to protect against dust pollens or any allergens we can inhale. It starts to build up and gets thick in case of any infection, allergy, or cold. Usually, after the simple home remedies, the mucus gets thin again, and the pressure and congestion are released. 

Getting a consultation is needed and helpful when the infection, congestion, and mucus in the throat stay persistent, and home remedies don’t work. 

FAQs about mucus in the throat

Why do I have so much phlegm in my throat all the time?

If you are constantly experiencing phlegm in your throat, most likely, it’s an allergic response to something you are continuously consuming or inhaling. It can also be due to any chronic underlying medical condition. Getting a medical consultation for effective consultation and a well-suited prescription is beneficial. 

Is it safe to use over-the-counter medications for mucus relief?

Yes, using over-the-counter medications for mucus relief and congestion in the back of the throat is safe and effective. The highly recommended over-the-counter medication is Mucinex, which can not only release nasal and throat congestion but also help effectively thin the mucus, eventually leading to relief of mucus. 

Should I be concerned if my mucus is discolored?

It depends on the time and nature of the cause that leads to the mucus. Usually, the mucus’s color is clear, indicating an allergic reaction or any dust/pollen that has gotten into the respiratory system. In case of an infection, Mucus might turn into green or yellow. If it goes away on its own, there is nothing to be concerned about; if it does not, get a medical consultation with a healthcare provider for effective treatment options. 

Should I swallow phlegm or cough it up?

Coughing or spitting the mucus is good, says Dr. Boucher. You are coughing the germs, bacteria, or viruses that cause the congestion. It can also help clear your throat and nasal pressure. Swallowing might irritate your gastrointestinal and respiratory tract more.
