Are Loss Of Mobility,vision,hearing, Dehydration Side Effects Of Clarithromycin?

My son was taking Clarithromycin for a viral infection he had. Last week he had loss of mobility, slurred speech, blurred and then loss of vision, loss of hearing, went as white as a ghost, then starting sweating then went a slight shade of yellow. We took him into the emergency section of hospital and they did an ECG, CT Scan and blood tests that all came back good except that he was dehydrated so they put him on a drip. They also found that his left ventricle to his heart was slightly enlarged.
