The NPA has written to the General Pharmaceutical Council (GPhC) saying current rules leave the door open for medicines to be supplied without appropriate checks “and the risk to patient safety remains”.
The call comes amid warnings of a boom in demand for weight-loss jabs this year as ministers look to expand the rollout of the medication on the NHS.
Mr Kaye told the PA news agency: “Obesity is one of the biggest challenges facing our country and pharmacies want to play their part in helping patients lose and maintain a healthy weight.
“Weight-loss injections can play an important role in efforts to tackle obesity when prescribed as part of a carefully managed treatment programme for patients who are most in need of support.
“However, we are concerned that the current regulations allow some patients to inappropriately access weight-loss injections without proper consultation or examination of historical medical records.”
