Are P and GSL medicines as effective and safe as POM medicines?
If a medicine switches from POM to P or from P to GSL, the active ingredient remains exactly the same. This means that the medicine is just as effective as when it had to be prescribed by a qualified prescriber. It also means that there is the same risk of side effects if you take too high a dose or if you do not follow the instructions on the label. Therefore, it is important that you follow the instructions carefully. Your pharmacist will be able to advise you about any possible side effects.
