Can antihistamines cause dry mouth?

Yes, antihistamines can cause dry mouth as a side effect. This applies to both first-generation and some second-generation types. If you notice this, speak to your doctor or pharmacist.

Key points:

• Antihistamines reduce saliva production, leading to dry mouth.
• First-generation antihistamines are more likely to cause this side effect.
• Second-generation antihistamines can also cause dry mouth, though less often.
• Medication-related side effects like this affect oral health.
