Side Effects


Clinical Studies Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in one clinical study of a drug cannot be directly compared with rates in the clinical studies of the same drug or another drug and may not reflect the rates observed in practice.

The safety profile of CEPROTIN was based on 121 patients from clinical studies and compassionate use in severe congenital Protein C deficiency. Duration of exposure ranged from 1 day to 8 years. One patient experienced hypersensitivity/allergic reactions (itching and rash) and lightheadedness which were determined by the investigator to be related to CEPROTIN.

No inhibiting antibodies to CEPROTIN have been observed in clinical studies. However, the potential for developing antibodies cannot be ruled out.

Post-marketing Experience

The following adverse reactions have been identified during postapproval use of CEPROTIN:

Psychiatric Disorders: Restlessness

Skin and Subcutaneous Tissue Disorders: Hyperhydrosis

General Disorders and Administration Site Conditions: Injection Site Reaction

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
