Nothing: Claritin (loratadine) and most other nonsedating third generation antihistamines are very safe. The initial studies for Claritin (loratadine) were done at 40 mg (4 times the currently recommended dose). If a physical symptom is experienced after using any medication at an excessively high dose, the best resource is the "poison control" center. They are available 24/7 by calling 1-800-poison1.See 1 more doctor answer
I accidentally took 2 loratadine 10 mg tablets and it says take once a day. Should I go to the doctors?
Sounds ok, but...: Some people try 2 loratadine (Claritin) per day because 1 per day did not help. The recommended dose is 1 per day, for use as an allergy medication. So, people who try 2 per day should go back to 1 per day if they did not see a big improvement when taking 2 per day. They should ask their doctors to confirm a diagnosis and ask which other medication can help, instead of taking 2 Claritin per day.
It depends: There are two different doses of Claritin (loratadine) d - a twelve hour dose and a twenty four hour dose. Obviously, the 12 hour dose is recommended twice a day, 12 hours apart. If you were to take two 24 hour tablets, you would be getting the equivalent of 16 sudafed tablets. That could cause agitation, insomnia, rapid heart rate, and an elevation in blood pressure. That would not be recommended.
What happens if you accidentally take 2 claritins (loratadine) (10mg each) in 24 hours when you're supposed to only take one? Anything serious would happen?
Extra Claritin (loratadine): If you are in generally good health with normal kidney and liver function, and you are not taking other sedating medications, there are not likely to be serious consequences. The worst you might experience would be excessive drowsiness, sedation, etc so don't drive for 24 hours. Also do not consume alcohol or take other medications that are CNS depressants for 48 hours.
Mgt: I think it should not result in harmful side effects. If you do notice any changes, please report them right away to your PCP.See 1 more doctor answer
Probably: Doubling the dose may not provide additional relief and may be more likely to cause sedation.See 1 more doctor answer

I may have accidentally taken twice the Normal dose of otc Claritin (loratadine). Do I need to seek medical attention?
Yes, but why?: Studies of loritadine show the medication is well tolerated at twice the recommended 10 mg dose. However, the same studies show no added benefit of the double dose in symptom relief over the regular dose schedule.See 1 more doctor answer
Not in the USA: The full adult dose of Loratadine in other parts of the world is 20 mg. That was the most effective dose. This amount caused a 12-14% drowsiness rate. This was not acceptable for marketing in the USA. The 10 mg dose was tested against Chlorpheniramine in order to find a non-drowsy dose and it worked. So for most 10 mg is fine. Worse allergy, 20mg would help and a few will develop drowsiness.See 1 more doctor answer
Yes, but why?: Studies of loritadine show the medication is well tolerated at twice the recommended 10 mg dose. However, the same studies show no added benefit of the double dose in symptom relief over the regular dose schedule. If one is not working well, you may want to try otc fexofenadine or a steroid nasal spray.
Why?: Studies during development showed that the body was very tolerant to loratadine, with no significant side effects at twice the recommended dosage. However, they also found that there was no increased benefit with twice the dosage over the normal dose. Why take more if there is no benefit?See 1 more doctor answer
