Certain signs and symptoms have been reported in association with the use of this drug but, in these instances, it is often impossible to determine the relationship of the underlying disease and drug administration to the reported reaction. Such reactions include maculopapular erythema, increase in blood pressure, paresthesia, malaise, aches and edema of the extremities, glossitis, anorexia, and nausea and vomiting. Alopecia alone and with associated nail growth disturbance have been reported rarely; these side effects subsided without interruption of treatment.

TESLAC (testolactone) is classified as a controlled substance under the Anabolic Steroids Control Act of 1990 and has been assigned to Schedule III.

When administered concurrently, testolactone may increase the effects of oral anticoagulants; monitor and adjust anticoagulant dosage accordingly.
