Cetirizine has been trending online in Kenya following claims that the commonly used allergy medication can cause dryness and affect natural lubrication in women.

The discussion has sparked curiosity about the drug, which is widely used to manage allergy symptoms such as sneezing, a runny nose, itchy eyes and skin reactions.

Cetirizine belongs to a class of medicines known as antihistamines, which work by blocking histamine, a chemical released by the body during allergic reactions.

Although some antihistamines can contribute to dryness in the body, dryness in women’s private parts is not listed among the common side effects of cetirizine in official medicine information.

Here are some of the things Kenyans should know about the medication, including what it treats, how it works and its possible side effects.

Can cetirizine cause dryness in women?

Some antihistamines may contribute to dryness in the body by reducing natural moisture. This may affect intimate lubrication, potentially causing discomfort or pain during intercourse.

However, there is limited evidence directly linking cetirizine to intimate dryness. The medication has also not been established as a cause of tightening or loss of elasticity. Other factors, including hormonal changes, pregnancy, breastfeeding and menopause, can contribute to the problem.

What does cetirizine treat?

Cetirizine is used to manage allergy symptoms caused by the release of histamine, a chemical produced by the body during allergic reactions.

It helps relieve sneezing, a runny nose, itching of the nose and throat, and red, itchy or watery eyes.

The medication is also used to treat urticaria, commonly known as hives, which causes itchy, raised red bumps on the skin.

How does cetirizine work?

When the body encounters allergens such as dust, pollen or animal hair, it releases histamine, triggering symptoms associated with allergic reactions.

Cetirizine works by blocking histamine receptors, reducing the effects of the chemical and providing relief from allergy symptoms.

It is classified as a second-generation antihistamine, meaning it is generally less likely to cause drowsiness than older allergy medications, although sleepiness remains a possible side effect.

How should you take cetirizine?

Cetirizine is available in different forms, including tablets, chewable tablets, capsules, orally dissolving tablets and syrup.

It is generally taken once daily, with or without food, depending on the prescribed dose.

Adults and children aged 12 years and above commonly take 10mg once daily. Children require age-appropriate doses, while people with kidney problems may need adjustments.

Users should follow the instructions on the packaging or advice from a healthcare professional and should not take more than the recommended amount.

What are the possible side effects?

Although cetirizine is generally well tolerated, it can cause side effects in some people. These include drowsiness, excessive tiredness and dry mouth. Some users may also experience headaches or dizziness.

The medication can affect alertness, so people who experience sleepiness should avoid driving or operating machinery. Alcohol may also increase drowsiness and should be avoided while taking cetirizine.

Who should be cautious?

People with kidney or liver disease should consult a healthcare professional before taking cetirizine.

Pregnant and breastfeeding women should also seek medical advice before using it. Patients should disclose other medicines and supplements they take to avoid possible interactions.

Anyone who develops difficulty breathing, swallowing or swelling around the mouth or tongue should seek emergency medical attention, as these could indicate a severe allergic reaction.

It is worth noting that cetirizine helps control allergy symptoms but does not cure allergies. It should be taken according to recommended instructions, rather than simply because it is trending online.
