One extra dose or a in a different form should cause no harm

You should be okay and no need to induce vomiting, however, if you have any unpleasant symptoms, you should contact your Dr. or if severe side effects, visit the emergency room. The reason behind spacing the dosages is to avoid the risk of seizure. Next dosages try spacing them out approximately 8 hours apart, and take the second dose before 4pm to avoid sleep problems
