What over-the-counter drugs reduce vaginal sensitivity?
Common over-the-counter (OTC) medications such as antihistamines and some cold remedies may reduce vaginal sensitivity by causing dryness of the mucous membranes.
Detailed Medical Explanation
Antihistamines (such as loratadine and cetirizine) are the most common OTC drugs that cause mucosal dryness, including vaginal dryness, which can reduce sensitivity and sexual comfort. Some decongestants or combination cold medicines may also contribute to this effect. The symptoms are typically reversible after stopping the medication. NHS: Antihistamines.
Clinical Context
If you experience vaginal dryness or sensitivity changes with OTC medication, stop use and consult your pharmacist or GP if symptoms persist.
Evidence-Based Approaches
NICE and NHS recommend using lubricants and reviewing medications if vaginal dryness or reduced sensitivity occurs (NICE CKS).
