Effects of other drugs, drug classes and over-the-counter products on GLUCOBAY

Effects of other drugs, drug classes and over-the-counter products on GLUCOBAY

  • The following medications may interact with GLUCOBAY:
  • Oral antidiabetic agents: When GLUCOBAY is prescribed in addition to existing treatment with
  • sulfonylureas, or metformin, the dosage of the sulfonylurea or metformin must be appropriately reduced
  • should the blood glucose levels fall in the hypoglycaemic range. In individual cases hypoglycaemiarelated impairment of consciousness may occur.
  • Neomycin: Due to neomycin-induced malabsorption of carbohydrate, concomitant administration of
  • neomycin may lead to an enhanced reduction of postprandial blood glucose and to an increase in the
  • frequency and severity of gastrointestinal adverse reactions. If the symptoms are severe, a temporary
  • dose reduction of GLUCOBAY may be warranted.
  • Cholestyramine: The concomitant administration of cholestyramine may enhance the effects of
  • GLUCOBAY, particularly the reduction of postprandial insulin levels. If both GLUCOBAY and
  • cholestyramine therapy are withdrawn simultaneously, caution should be exercised as a rebound
  • phenomenon has been observed in non-diabetic subjects.
  • Digoxin: In individual cases, GLUCOBAY may affect digoxin bioavailability, which may require dose
  • adjustment of digoxin.
  • Intestinal Adsorbents: On the basis of general considerations, the simultaneous use of intestinal
  • adsorbents (e.g. charcoal), and digestive enzyme preparations (e.g. amylase, pancreatin) may reduce the
  • effect of GLUCOBAY and should be avoided wherever possible.
  • Antacids: The concomitant administration of GLUCOBAY and antacids does not alter the effect of
  • GLUCOBAY. The administration of antacid preparations is unlikely to ameliorate the gastrointestinal
  • symptoms of GLUCOBAY and therefore should not be recommended for this purpose.
