Answer: (A.) Use of vitamin supplements
Xerostomia, or dryness of the mouth, can result because of many different factors:
- Side effect of medications such as anti-hypertensive drugs (especially diuretics), anti-anxiety drugs (clozapine – Clozaril), anti-histamine drugs (e.g., Benadryl), anti-depressant drugs (e.g., citalopram – Celexa), anti-emetic drugs (e.g., AlkaSeltzer), anti-Parkinson’s drugs (e.g., Levodopa)
- Diseases such as Sjogren’s or diabetes
- Radiation therapy if salivary glands are destroyed
Supplemental vitamin intake will not produce xerostomia, and on the contrary is more likely to help provide nutrients necessary for the maintenance of a healthier oral environment.
