Crookes Healthcare is recalling all Karvol vaporisers and refill bottles, as a precautionary measure. This is because of a small number of instances where the refill bottle has been accidentally removed from the plug-in vaporiser unit, allowing direct contact with the liquid. The company says that pharmacists/retailers should refund all Karvol vaporisers and refills and that it will reimburse them for these and other remaining stock, which should be removed and quarantined. Further information can be obtained from the company's customer helpline (tel 0800 0932075).
