Levonorgestrel is a well established progestogen with anti-oestrogenic activity. The safety profile following systemic administration is well documented. A study in monkeys with intrauterine delivery of levonorgestrel for 12 months confirmed local pharmacological activity with good local tolerance and no signs of systemic toxicity. No embryotoxicity was seen in the rabbit following intrauterine administration of levonorgestrel.
Animal experiments with Norlevo have shown virilisation of female foetuses at high doses.
Preclinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeat dose toxicity, mutagenicity and carcinogenicity potential, beyond the information included in other sections of the SmPC.
Norlevo is supplied in a sterile pack which should not be opened until required for insertion. Each system should be handled with aseptic precautions. If the seal of the sterile envelope is broken, the system inside should be disposed of in accordance with the local guidelines for the handling of biohazardous waste. Likewise, a removed Norlevo and inserter should be disposed of in this manner. The outer carton package and the inner blister package can be handled as household waste.
No special requirements.
