The proper administration of ear drops requires tilting the head toward the opposite shoulder, pulling the superior aspect of the auricle upward, and instilling the ear drops into the ear canal. The patient should then lie on the side opposite the side of administration for 20 minutes. To maximize medication absorption, the patient should have a cotton ball placed in the ear canal. Supine positioning is not used, and the ear canal does not need to be rinsed prior to drug administration.

A patient who suffers cholinergic overdose will experience sweating, flushing, abdominal cramps, and nausea. An accurate diagnosis may be determined from timing in relation to medication. Signs and symptoms having an onset within approximately 1 hour after a dose of anticholinesterase drug are likely to be caused by cholinergic crisis. Signs and symptoms beginning 3 hours or more after a drug dose are more likely to be caused by myasthenic crisis. These symptoms are not the result of anaphylaxis or pulmonary edema.
