The dosage of Claritin that you are prescribed will be affected by factors such as your age and if any other medical conditions are present. For example, the recommended dose for adults and children age six and over is 10 mg a day. If you have medical conditions like liver or kidney disease, you may require a lower amount.

An Introduction to Dosing With Claritin

The dose of Claritin® (loratadine) that your healthcare provider recommends will vary depending on a number of factors, including:
  • Your age
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Claritin Dosage for Adults and Older Children

The recommended Claritin dose for most adults and children age six and over is Claritin 10 mg once daily. This dose is equivalent to any of the following:
  • One Claritin 10 mg tablet
  • One Claritin 24-Hour RediTab®
  • One Claritin 10 mg Liqui-Gel®
  • Two teaspoonfuls (10 mL) of Claritin syrup
  • Two Claritin chewable tablets.
If you are using Claritin 12-Hour RediTabs, the recommended dose is one tablet (5 mg) twice daily.
If you have liver or kidney disease, you should consult your healthcare provider before taking Claritin, as you may need a lower dosage.

Doses for Young Children

The recommended Claritin dose for children ages two through five is Claritin 5 mg once daily. This dose is equivalent to one Claritin chewable tablet or one teaspoonful (5 mL) of Claritin syrup. Consult your child's healthcare provider if your child has liver or kidney problems, as a lower dosage may be recommended.
