DRUG INTERACTIONS
Drug/ Laboratory Test Interactions
Certain endocrine and liver function tests may be affected by estrogen-containing oral contraceptives. The following similar changes may be expected with larger doses of estrogen:
- Increased sulfobromophthalein retention.
- Increased prothrombin and factors VII, VIII, IX, and X; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability.
- Increased thyroid-binding globulin (TBG) leading to in-creased circulating total thyroid hormone; as measured by PBI, T4 by column, or T4 by radioimmunoassay. Free T3 resin uptake is decreased, reflecting the elevated TBG; free T4 concentration is unaltered.
- Impaired glucose tolerance.
- Decreased pregnanediol excretion.
- Reduced response to metyrapone test.
- Reduced serum folate concentration.
- Increased serum triglyceride and phospholipid concentration.
