Vocalzone is recommended for adults, elderly and children over the age of 12. Up until December 2017, Vocalzone was a licenced medicine, which meant we had a full pharmacovigilance system in place to track any medical enquiries. Whilst we have now come of our medical licence to enable us to release new flavours and variants of our range, we have maintained a detailed tracking and monitoring system so you can be rest assured when using Vocalzone. If you have any concerns regarding treatments you may currently be taking, consult your pharmacist or doctor before use.
