As the owner of ELLEMES Medical Spa of Atlanta, GA, I often get asked about the effectiveness of Botox for various conditions, including sialorrhea. Patients who suffer from this condition experience excessive saliva production, which can be embarrassing and uncomfortable. But does Botox really work to reduce saliva production? In this blog post, I’m going to discuss the current research on the use of Botox for treating sialorrhea and answer the question: Can Botox be used for treating sialorrhea?

What is Sialorrhea?

Sialorrhea, also known as hypersalivation or ptyalism, is a medical condition that is characterized by the excessive production of saliva. This condition can be caused by a variety of different factors, including certain medical conditions, certain medications, or even psychological issues such as stress and anxiety. It is most commonly seen in people with neurological conditions, such as Parkinson’s disease or cerebral palsy.

The Effects of Sialorrhea

Sialorrhea can have a major impact on a person’s quality of life. In addition to the embarrassment and discomfort caused by excessive saliva production, it can also lead to other issues such as cavities and dehydration. It can also interfere with speech and the ability to swallow. In some cases, it may even lead to aspiration pneumonia.

Botox for Sialorrhea

Botox is a type of neurotoxin derived from a bacteria called Clostridium botulinum. It is most commonly used for cosmetic purposes, as it is able to temporarily paralyze facial muscles in order to reduce the appearance of wrinkles. However, it has also been used for therapeutic purposes, such as reducing excessive sweating and treating certain neurological conditions. Research has also shown that Botox can be used to reduce saliva production in people with sialorrhea.

How Does Botox Work for Sialorrhea?

Botox works by blocking the transmission of nerve signals to the salivary glands. This reduces the amount of saliva that is produced, and can help to reduce the symptoms of sialorrhea. The effects can be seen within a few days after treatment, and typically last for several months.

Safety and Side Effects of Botox for Sialorrhea

Botox is generally considered to be a safe and effective treatment for sialorrhea, with few side effects. However, it is important to be aware that there is always a risk of developing an infection or allergic reaction to the injectable. Additionally, there is a risk of drooling or difficulty speaking after the injection.


In conclusion, Botox is a safe and effective treatment for sialorrhea. It works by blocking nerve signals to the salivary glands and can help to reduce the excessive production of saliva in people with this condition. The effects typically last for several months, but it is important to be aware of the potential side effects. If you are considering Botox for sialorrhea, it is important to consult with a qualified medical professional.
