"I am writing to give you advance notice that Champix (varenicline tartrate) will be re-introduced into the UK market in late June or early July of this year. As you may recall, in 2021, Pfizer paused the distribution of Champix worldwide out of an abundance of caution following an evaluation that identified Champix contained levels of N-nitroso-varenicline above an acceptable intake (AI) limit set by regulatory authorities.

Since then, regulatory authorities have updated guidance on AI limits for N-nitroso-varenicline. Pfizer conducted rigorous and comprehensive testing that has confirmed that Champix meets all regulatory requirements set by regulatory agencies. With this update to the acceptable intake (AI), coupled with Pfizer’s actions to lower the levels of N-nitroso-varenicline observed in Champix, Pfizer will re-introduce supply in the U.K."
