Typical opioid withdrawal include clinical symtpoms of piloerection, nausea, vomiting and diarrhea. If you were to see seizure, another etiology other than opioid withdrawal should be investigated.
Except in the case of neonates borne to women who have been taking opioids chronically such as a methodone patient. Once the child is born, symptoms of withdrawal may take days to weeks to materialize though seizures typically occur <10 days. The child is at increased risk of SIDS as well.
