Botox Injections into Salivary Glands: Caring for your child at home After the procedure

Your child has had Botox injected into the salivary​ (say: SA-ly-ver-ee) glands. This brochure explains how to care for your child at home after the procedure, and when to call for help.

When Botox is injected into the salivary glands, it decreases the amount of liquid produced by the glands in the mouth.

When to see a doctor 

Phone your specialist or Image Guided Therapy (IGT), or go to the nearest Emergency Department right away if your child has any of the following:

  • fever greater than 38°C (100.4°F)
  • trouble swallowing
  • weakness of face muscles
  • trouble breathing
  • trouble speaking

Be sure to let the Emergency Department staff know that your child has had Botox injections.


Your child may have a bath or shower the day of the injections.


If your child is feeling well enough after the anesthetic, they can return to eating what they normally eat. It is also important to give your child plenty of fluids for 48 hours after the procedure.

Pain relief

Your child may have some mild discomfort after the procedure. If needed, give your child acetaminophen (Tylenol®).


Your child can resume all regular activities as soon as they feel ready to do so.

Key points

  • Botox injections into the salivary glands decrease drooling.
  • Watch for symptoms from the time the injections are done until 4 weeks after the injections. These include trouble swallowing, speaking, and breathing.
  • Your child can resume all regular activities when they feel able to do so.
  • If your child has any difficulty breathing, take them to the nearest Emergency Department right away.
