Special information if you are pregnant or breastfeeding
Return to topThe effects of Precose during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, tell your doctor immediately. Since studies suggest the importance of maintaining normal blood sugar levels during pregnancy, your doctor may prescribe injected insulin. It is not known whether Precose appears in breast milk. Because many drugs do appear in breast milk, you should not take Precose while breastfeeding.
Recommended dosage for Precose
Return to topADULTS
The recommended starting dose of Precose is 25 milligrams (half of a 50-milligram tablet) 3 times a day, taken with the first bite of each main meal. Some people need to work up to this dose gradually and start with 25 milligrams only once a day. Your doctor will adjust your dosage at 4- to 8-week intervals, based on blood tests and your individual response to Precose. The doctor may increase the medication to 50 milligrams 3 times a day or, if needed, 100 milligrams 3 times a day. You should not take more than this amount. If you weigh less than 132 pounds, the maximum dosage is 50 milligrams 3 times a day.
If you are also taking another oral antidiabetic medication or insulin and you show signs of low blood sugar, your doctor will adjust the dosage of both medications.
CHILDREN
Safety and effectiveness of Precose in children have not been established.
Overdosage

These symptoms usually disappear quickly. However, in the event of an overdose, do not take any carbohydrate drinks or meals until the symptoms have passed.
