Loratadine is generally very safe. If you or your child take too much, it is unlikely to harm you.
There can be several reasons for Claritin not working:
You didn't start taking Claritin soon enough. You don't take Claritin every day. You're expecting Claritin to be a decongestant. The antihistamine Claritin contains (loratadine) doesn't work for you as well as other antihistamines would.
Even if you're severely suffering from allergies, with incredibly watery eyes or a scratchy throat, it's not recommended to take more than the daily dosage as there can be side effects that occur.
“Zyrtec is found to be more potent, or stronger, in laboratory studies, compared with Claritin,” says Dr. Kung. “It also reaches a higher concentration in the skin, which can be more helpful for skin-related allergies. However, Zyrtec has a greater chance of making you sleepy while taking it.”
Official answer. No, the maximum recommended daily dose of loratadine is 10mg once daily.
Yes, someone can overdose on Claritin® (loratadine). When taking Claritin®, do not go over the recommended dosage. Do not take another dose before the instructions say to do so.
If a healthy adult takes only a slightly higher dose of antihistamine, such as accidentally taking two pills instead of one, their symptoms may not be serious, or they may not have any symptoms. However, a larger overdose, especially in children or older adults, may cause serious symptoms.
The maximum recommended daily dose is 20 mg, do not exceed this dose, unless told to do so by your doctor.
Best in the evening: Allergy meds
Once-daily antihistamines, such as Claritin, reach their peak eight to 12 hours after you take them, so using them at dinnertime or before bed means better control of morning symptoms.
For instance, Claritin comes in both 12-hour and 24-hour tablets. So if you took Claritin 12-hour in the morning and want to take Zyrtec that night, you may be able to. However, if taking Zyrtec or a 24-hour Claritin product, you should not take more than one dose of either medication over the course of 24 hours.
Do not take 2 antihistamines together unless recommended by your doctor.

Cetirizine is the most potent antihistamine available and has been subjected to more clinical study than any other.
Loratadine has a rapid onset of action; it works within 1 to 3 hours, its effects peak within 8 to 12 hours, and elimination occurs through the fecal and renal routes. It has a half-life of approximately 8 hours, and the half-life of its active metabolite is 28 hours.
This medication is an antihistamine that treats symptoms such as itching, runny nose, watery eyes, and sneezing from "hay fever" and other allergies. It is also used to relieve itching from hives.
