  • dizziness,
  • dry mouth,

Dosage for Suprenza

Dosage should be individualized to obtain an adequate response with the lowest effective dose. When tolerance to the effect of Suprenza develops, the recommended dose should not be exceeded in an attempt to increase the effect; rather, the drug should be discontinued.

Suprenza During Pregnancy or Breastfeeding

Suprenza is contraindicated during pregnancy because weight loss offers no potential benefit to a pregnant woman and may result in fetal harm. It is not known if Suprenza is excreted in human milk; however, other amphetamines are present in human milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
