Signs and symptoms of overdose (restlessness, tremors, convulsion, coma, cardiac arrest) may occur within 15 to 20 minutes and death has been reported within 1 hour of ingestion.

Pregnancy Risk Factor
Animal reproduction studies have not been conducted. Information related to use in pregnancy is limited (Heinonen 1977).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience constipation, dizziness, fatigue, rhinitis, nausea, or headache. Have patient report immediately to prescriber behavioral changes, confusion, hallucinations, or numbness and tingling of mouth, throat, tongue, and face (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
