Quinestrol Disease Interactions

There are 3 disease interactions with quinestrol:


Estrogens (applies to quinestrol) angioedema

Moderate Potential Hazard, Moderate plausibility.

The use of exogenous estrogens may induce or exacerbate symptoms of angioedema, particularly in women with hereditary angioedema. Close monitoring is recommended when prescribing these agents to patients predisposed to angioedema.


Estrogens (applies to quinestrol) melasma

Moderate Potential Hazard, Moderate plausibility.

The use of exogenous estrogens may occasionally cause chloasma, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking combination oral contraceptives.


Estrogens/progestogens (applies to quinestrol) retinal thrombosis

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Visual Defect/Disturbance

Estrogens and progestogens may cause retinal thrombosis. Oral contraceptives should be discontinued if there is unexplained partial or complete loss of vision; onset of proptosis or diplopia; papilledema; or retinal vascular lesions. Therapy with these agents should be administered cautiously in patients who have preexisting ocular problems and appropriate diagnostic and therapeutic measures should be instituted. Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
