The Pharmaceutical Society of Kenya (PSK) has issued a stern warning to women against the dangerous practice of inserting cetirizine allergy tablets into their vaginas to achieve tightness. The professional body described the trend, which has been widely promoted on social media, as unsafe and medically hazardous.
The warning follows the circulation of TikTok posts claiming that the antihistamine, commonly used to treat allergies, could reduce vaginal moisture and create a sensation of tightness during sexual intercourse.
However, the pharmacists’ association said the drug-induced dryness does not strengthen vaginal muscles and could expose users to pain, discomfort and tissue injuries.
“Dryness is not tightness… instead, it may increase friction, discomfort, and the risk of tissue injury,” the PSK said.
The professional body, in a statement issued on Thursday, stressed that cetirizine was formulated for oral use and had not been tested for insertion into vaginal tissue.
“Cetirizine is an allergy medicine, taken by mouth. It is not approved or tested for any other purpose, and definitely not for vaginal use,” it said.
The society added: “Inserting oral tablets is unsafe. Cetirizine tablets are made to be swallowed. Their ingredients have not been tested on delicate vaginal tissue.”
Cetirizine is commonly prescribed to relieve allergy symptoms such as sneezing, runny nose, itchy eyes and skin reactions, including hives.
The online trend has generated debate, with some social media users endorsing the practice while others questioned its safety.
Reports have also emerged of increased demand and rising prices of the drug in some pharmacies, particularly in Nairobi, raising concerns that people who genuinely need it for allergy treatment could face difficulties obtaining it.
The PSK said it was aware of reports of shortages and urged pharmaceutical retailers not to exploit the situation by increasing prices.
It also advised women who had already tried the practice to discontinue it and seek medical attention if they experienced complications.
“If you have already tried it. Stop. See a doctor if you have pain, bleeding, burning, itching, unusual discharge, or fever,” the statement said.
The society further urged pharmacists not to knowingly dispense medicines for purposes for which they were not intended and encouraged them to report any adverse effects to relevant health authorities.
According to BBC, the warning came a day after Kenya’s Ministry of Health expressed concern over the trend.
A senior health official, Ouma Oluga, said some social media users appeared to be treating expert medical advice as a joke without considering the possible consequences.
Oluga also suggested that authorities could introduce a system to monitor the distribution and purchase of medicines to identify possible misuse, although no formal decision on the proposal has been announced.
The PSK also called on social media influencers and content creators to exercise caution when sharing health-related information, warning that unverified claims could put lives at risk.
It advised the public to seek professional guidance before using medicines for purposes other than those for which they were developed.
“Check with a pharmacist before using any medicine for a purpose it was not made for.
“Do not rely on social media for medical advice,” the society said.
What You Should Know
This warning follows a viral social media trend claiming that antihistamines can dry out the vagina to create a tightening sensation during intercourse. However, medical professionals clarify that dryness is not the same as tightness and does not improve muscle strength.
- Major Health Risks: Doctors warn that this practice causes excessive friction, which can lead to painful tissue injuries, bleeding, and infections in sensitive areas.
- Drug Shortages: The misuse of this allergy medication has caused a spike in demand and prices, making it difficult for patients who genuinely need the drug for respiratory allergies and hives to find it.
- Official Guidance: Health authorities advise anyone who has tried this method to stop immediately and see a doctor if they experience burning, itching, or unusual discharge.
