Comparing two doses of cetirizine for sudden hives
Treatments studied
Part of Skin clinical trials.
This trial tests whether a higher dose of cetirizine (an allergy medicine) works better than the standard dose for treating sudden hives in adults. It may help people who have had new hives in the last day and are not taking certain other medicines.

This trial tests an injectable medication (cetirizine, a type of antihistamine) to see if it quickly relieves itching and hives in adults with acute (short-term) hives. It is for people whose hives have lasted less than 6 weeks and who still have bothersome symptoms.
This study tests different treatment options for people with chronic hives (urticaria) that have lasted more than 6 weeks. It aims to find which treatment works best and is safe.
This Phase 1 study compares how a 10 mg cetirizine gummy absorbs in your body versus a 10 mg cetirizine tablet. The goal is to see whether the gummy works in a similar way, which may help confirm it’s reliably absorbed.
This trial tests an experimental medicine for chronic hives (called chronic spontaneous urticaria). It is for people whose hives still bother them about once or twice a month despite daily treatment, and who do not have heart problems.
This trial tests a new medication called THB335 for people with chronic spontaneous urticaria (CSU), which causes hives and itching for months without a clear cause. The study will see if the drug can reduce hives and itching better than a placebo (a pill with no active medicine).
This trial tests a new medicine called BBT001 for people with chronic spontaneous urticaria (long-lasting hives without a known cause). It aims to see if the drug is safe and helps reduce itching and hives.
