Can Antibiotics Cause Excess Saliva?

Published in Antibiotic Side Effects 2 mins read

Yes, antibiotics can potentially cause an increase in saliva production.

Understanding Antibiotics and Saliva Production

When taking medication, the body can sometimes react in unexpected ways. One potential side effect of certain drugs is a change in salivary flow. Based on the provided information:

  • Some of the antibiotics may cause hypersalivation. This means that in some individuals taking specific types of antibiotics, there could be an increase in the amount of saliva they produce.

This side effect, known medically as hypersalivation or sialorrhea, can vary in intensity depending on the individual, the specific antibiotic being used, and the dosage.

What to Do If You Experience Increased Saliva

If you notice an increase in saliva production after you have started taking a new antibiotic, it's important to address it. The reference suggests:

  1. See a doctor: This is the crucial first step. They can evaluate your symptoms and determine if the antibiotic is the likely cause.
  2. Discuss options: Your doctor might consider:
    • Changing your dosage of the current antibiotic.
    • Recommending a different medication entirely.

It's vital not to stop taking your antibiotic or change the dosage yourself without consulting a healthcare professional, as this could affect the treatment of your infection.

Why Does This Happen?

While the exact mechanisms can vary depending on the specific antibiotic, some medications can interfere with the body's autonomic nervous system, which controls involuntary functions like salivation. Others might act directly on salivary glands or alter nerve signals in a way that stimulates saliva production. However, the primary takeaway is that it is a known potential side effect for some antibiotics.

If you are concerned about changes in saliva production or any other new symptoms after starting an antibiotic, prompt consultation with your doctor is recommended.
