Pharmacists raise alarm over cetirizine Vaginal use

Pharmacists and health authorities in Kenya have warned women against inserting cetirizine tablets into their vaginas following the spread of misleading social media claims promoting the allergy medication as a method of vaginal tightening.

The warning comes after posts circulating on TikTok and other social media platforms suggested that cetirizine, an antihistamine commonly used to treat allergic reactions, could reduce vaginal moisture and make the vagina feel tighter during sexual intercourse.

However, medical experts have dismissed the claims, explaining that reduced vaginal lubrication does not mean that vaginal muscles become tighter or stronger.

The Pharmaceutical Society of Kenya (PSK), the professional body representing pharmacists in the country, issued a public warning on Thursday, November 5, 2026, describing the practice as medically unsafe.

PSK explained that cetirizine is designed to be swallowed and is commonly prescribed to relieve allergy symptoms such as sneezing, runny noses, itchy eyes and skin reactions.

The society cautioned that the tablets have not been tested or approved for application to vaginal tissues, which are particularly sensitive.

It further warned that inserting the medication could cause irritation, burning sensations, soreness, pain and possible tissue damage.

According to the pharmacists, vaginal dryness should never be confused with muscle tightening, as reduced lubrication can increase friction during sexual intercourse, potentially resulting in discomfort and injuries.

The warning was also reinforced by Kenya’s Pharmacy and Poisons Board (PPB), which said there was no established scientific evidence supporting the use of cetirizine for vaginal tightening.

Regulator cautioned that using pharmaceutical products outside their approved purposes could interfere with the vagina’s natural protective environment and increase the risk of infections.

The controversy has also reportedly triggered increased demand for cetirizine in some Kenyan pharmacies, with reports of rising prices and stock shortages, particularly in Nairobi.

PSK expressed concern that the trend could affect patients who genuinely depend on the medication to manage allergic conditions.

It urged pharmacists not to exploit the situation by increasing prices or knowingly selling the drug for inappropriate purposes.

Meanwhile, Principal Secretary for Medical Services Ouma Oluga raised concerns about the influence of misleading health information on social media, warning that people could expose themselves to serious health complications by following unverified medical advice.

He also suggested introducing mechanisms to monitor medicine distribution and purchasing patterns to help identify possible misuse, although no final decision has been announced.

PSK advised women who have already inserted cetirizine tablets into their vaginas to stop immediately and seek medical attention if they experience pain, bleeding, burning, itching, unusual discharge or fever.

The society also urged social media influencers and content creators to exercise responsibility when sharing health-related information.
