Does dry mouth due to Botox for cervical dystonia go away when Botox wears off?

If the salivary glands were affected by your Botox treatment the dry mouth should improve gradually as the Botox wears off. The effects of Botox are temporary so this should not be a permanent issue for you.

Cervical dystonia is a muscle problem in the neck, and it's not clear how either your parotid salivary glands or submandibular salivary glands may have been injected. Just as Botox prevents sweating, when it's injected into a salivary gland, it decreases saliva production. I believe you'll start feeling improvement 6 to 8 weeks after your treatment. I hope this helps. Sincerely, Dr. Joseph

Dry mouth (xerostomia) is a known side effect of Botox (botulinum toxin) injections, including those used for cervical dystonia. This occurs because Botox can affect the salivary glands, reducing saliva production.

The good news is that the dry mouth typically resolves as the effects of the Botox wear off. Botox injections are not permanent, and their effects generally last about three to four months. Once the Botox wears off, the function of the affected glands usually returns to normal, and the dry mouth should subside.

However, if the dry mouth persists beyond the period when the Botox is expected to wear off, it is advisable to consult with your healthcare provider. Persistent symptoms could indicate another underlying issue that may need to be addressed.

Dry mouth due to Botox for cervical dystonia should go away as the effects of the Botox wear off, typically within three to four months. If it doesn't, follow up with your physician for further evaluation.
