You have been advised to start a new tablet called ACARBOSE. You should start taking it as follows:

Weeks 1-2  1/2 tablet (25mg) once daily 
Weeks 3-4 1 tablet (50mg) once daily
Weeks 5-6 1 tablet (50mg) twice daily
Weeks 7-8 1 tablet (50mg) three times a day
Week 9 onwards 2 tablets (100mg) three times a day.

Stay on this dose until you see the doctor again.

The tablets should be swallowed whole or chewed with the first mouthful of food. If you experience any bowel symptoms (e.g wind) return to the previous dose and try increasing the dose again after another 2 weeks.
