Claritin (loratadine): Hello, I have treated many people with allergy with antihistamines. Even though they are listed as non sedating, some people react to these medications in an unexpected fashion. Sedation may still occur and if this is present, I usually recommend using this medication if needed at night before sleep. It will still work for 24 hours and may help with allergy and sleep. ...Read more
What's causing my tiredness, pollen allergies or the Claritin (loratadine) I take for it? I have been so tired since pollen season started.
Sleep: Sleep apnea could be the main reason but Claritin (loratadine) does have a mild sedative effect in some more than others. Sleep disruption because of allergy symptoms is also common.

Have really bad nose congestion and I took one Claritin (loratadine) d non drowsy. I am starting to feel really tired, is this normal? Also, there isn't much relief
Yes but: Claritin can indeed cause drowsiness in a few people especially when the dose is doubled. On the other hand, th decongestant part (D) tends to keep people awake and thus your reaction is not common but not totally unexpected. We rarely use oral decongestant nowadays given that nasal steroid /nasal antihistamine are more effective with far less side effects. ...Read more
Woke up this morning very tired with a very sore hurting throat as if it's swollen in there. Even by night still not feeling better, and took claritin (loratadine)?
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. ...Read more

Why: Most studies show no significant side effects at this dose level in adults. They also show no increase in benefit by doubling the dose. Perhaps a trial of fexofenadine would be in order to see if another non sedating antihistamine would be more effective for you. Each person needs to find the med that works best for them. Its a bit more expensive, but sometimes works better. ...Read more

You shouldn't: Both medications are in the same class called non-sedating antihistamines and are effective for 24 hours. They should not be taken at the same time, but you can try both separately to see which is more effective for you. ...Read more
