A year-old woman took two mg verapamil SR tablets instead of 1. Benson et al. Of cases, estimated amounts ingested ranged from 0. No children ingesting less than 2. No level 1, 2, or 3 studies were found evaluating the threshold dose for the development of toxicity in adults or children 6 years of age and older with acute CCB exposures. The cases in which the exposure dose was known or estimated and reported are summarized in Table 5. In the vast majority of cases it was impossible to gauge the accuracy of the estimated dose.

Cases in which the exposure dose was either not reported or unknown are not included in the summary but can be found in the full evidence table. No level 1, 2, or 3 studies were found evaluating the threshold dose for the development of toxicity in children less than 6 years of age with acute CCB exposures. The results are summarized in Table 6. No level 1, 2, or 3 studies were found regarding chronic over 8 or more hours supratherapeutic CCB ingestions by older children and in adults.

These are summarized in Table 7. No data were found regarding chronic over 8 or more hours supratherapeutic CCB ingestions in children less than 6 years of age. It is important to note that the actual onset of effects likely occurred earlier than reported in many cases because the patients presented to HCFs well into the course of their poisonings. Therefore, the times recorded in the summary tables are estimates of the maximum possible delay to onset of symptoms.

In many such cases, there were mild clinical or electrocardiographic signs of toxicity early on, but in others these clues were either not reported or not clearly evident. There were no level 1, 2, or 3 studies investigating the time to onset of clinical effects after CCB overdose in adults. There were no level 1, 2, or 3 studies investigating the time to onset of clinical effects after CCB overdose in children less than 6 years of age.

Their data are tabulated in Table 9. These were limited to activated charcoal administration and induction of emesis with syrup of ipecac.

It is here that the details about localization, intensity and qualities of pain are perceived.
