Contraindications

4 CONTRAINDICATIONS PRIALT is contraindicated in patients with a known hypersensitivity to ziconotide or any of its formulation components. PRIALT is contraindicated in patients with any other concomitant treatment or medical condition that would render intrathecal administration hazardous. Contraindications to the use of intrathecal analgesia include the presence of infection at the microinfusion injection site, uncontrolled bleeding diathesis, and spinal canal obstruction that impairs circulation of CSF.

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Available data from postmarketing reports are insufficient to identify a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In an animal reproduction study, ziconotide did not cause embryo-fetal toxicity when administered to pregnant rats and rabbits during the period of organogenesis by continuous intravenous infusion at 400- and 940-times, respectively, the maximum recommended human dose (MRHD) of 19.2 mcg/day. In a pre- and post-natal development study, ziconotide did not affect pup development or reproductive performance when administered to rats by continuous intravenous infusion at 3800-times the MRHD (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Ziconotide caused embryo-fetal mortality in rats when given as a continuous intravenous infusion during the major period of organogenesis as evidenced by significant increases in post-implantation loss because of an absence or a reduced number of live fetuses. Estimated exposure for embryo-fetal mortality in the rat was approximately 700-fold above the expected exposure resulting from the maximum recommended human daily intrathecal dose of 0.8 mcg/hr (19.2 mcg/day). Ziconotide did not result in malformations when administered to pregnant rats by continuous intravenous infusion at doses up to 30 mg/kg/day or to pregnant rabbits up to 5 mg/kg/day during the major period of organ development. Estimated exposures in the female rat and rabbit were approximately 26,000-fold and 940-fold higher than the expected exposure resulting from the maximum recommended human daily dose of 0.8 mcg/hr (19.2 mc
