Imipramine poisoning in a child: lack of efficacy of resin hemoperfusion.

A three-year-old boy ingested up to 1,500 mg of the tricyclic antidepressant imipramine (Tofranil). He entered our facility within two hours of discovery, and multiple resuscitative efforts, which proved unsuccessful, followed. Resin hemoperfusion was used in an effort to remove imipramine from the systemic circulation.

Removal of prednisone and prednisolone by plasma exchange.

The effect of plasma exchange on the pharmacokinetics of prednisone and prednisolone was studied. Two patients undergoing plasma exchange while receiving oral prednisone therapy were studied. Patient 1 received prednisone 50 mg daily; patient 2 received 60 mg daily.
