I can't sleep. I was totally drowsy and about to drift off when my eyes popped open, my legs started becoming restless...and now sleep is far away for me. So what do I do? I get online and google "side effects for Claritin D" - this is what I found:
SIDE EFFECTS: Side effects of Claritin-D include stimulation of the nervous system leading to nervousness, restlessness, excitability, dizziness, headache, fear, anxiety, tremor, and even hallucinations and convulsions (seizures).
