Regulators in South Africa have recalled a batch of the popular Yaz Plus contraceptive pill, after a packaging mix-up which means the contraception could be potentially ineffective.

Manufacturer Bayer Ltd said women using pills from the affected batch should stop immediately and seek medical advice.

A packaging mix-up led to a number of blister packs carrying 24 inactive pills, instead of 24 hormone-containing active pills.

The issue affected only a limited number of packets in a specific batch labelled WEW96J, expiring in March 2026
