SIDE EFFECTS

See BOXED WARNINGS, WARNINGS, and PRECAUTIONS

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.

Table 4 summarizes the treatment-emergent adverse events with Estrasorb therapy.

DRUG INTERACTIONS

Drug/Laboratory Test Interactions

  1. Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, Vll-X complex, ll-VII-X complex, and beta-thromboglobulin: decreased levels of antifactor Xa and antithrombin III; decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity,
  2. Increased thyroid-binding globulin (TBG) levels leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 levels (by column or by radioimmunoassay) or T3 levels by radioimmunoassay. T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Patients on thyroid replacement therapy may require higher doses of thyroid hormone.
  3. Other binding proteins may be elevated in serum (i.e., corticosteroid binding globulin, and sex hormone binding globulin), leading to increased circulating corticosteroids and sex steroids, respectively. Free or biologically active hormone concentrations are unchanged. Other plasma proteins may be increased (angiotensinogen/renin substrate. alpha-1 -antitrypsin, ceruloplasmin).
  4. Increased plasma HDL and HDL-2 cholesterol subtraction concentrations, reduced LDL cholesterol concentration. and increased triglycerides levels.
  5. Impaired glucose tolerance.
  6. Reduced response to metyrapone test.
