Mucogel is not recommended for children under 12 years of age. In young children the use of magnesium hydroxide can produce hypermagnesemia, especially if they suffer from kidney problems or dehydration.

Other medicines and Mucogel

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

This is particularly important if you are taking:
