Overdose on Allerclear?

For those who know what allerclear is (the allergy medicine) I took a lot more of the pills than I should have. Can you overdose on Allerclear? And what are some symptoms of overdosing on it?
Answers:
How much more is a lot more?

You can overdose on allerclear. It is composed of 2 involved ingredients, one of which is a decongestant that has the side effect of being a cardiac stimulant (makes your heart beat fast)

If you have a feeling any of these: hallucinations; high fever; irregular or unusually slow or swift heartbeat; loss of consciousness; mental or mood changes; seizures; severe drowsiness or dizziness; unusual nervousness or excitement, you should telephone a doctor or poison control center. If you are seriously not feeling well, you should go to the hospital.
