The medicines regulator has issued a public alert to remind women prescribed weight loss injections to ensure they are also using effective contraception.

In particular, women taking tirzepatide (Mounjaro) should also use condoms if they are on oral contraception because the weight loss drug may reduce its effectiveness, the Medicines and Healthcare products Regulatory Agency (MHRA) said.
