The maximum recommended daily dose of cetirizine for adults and children 6 years and older is 10 mg once a day. Typically, this is taken as one 10 mg tablet per day for allergies or hives. For people over 65 years of age or those with kidney problems, the dose is usually lower, around 5 mg per day. Always follow your doctor's instructions or the package directions, and do not exceed the recommended dose to avoid side effects.
