Children should avoid contact with any unwashed or unclothed area where the medication has been applied. RxList does not provide medical advice, diagnosis or treatment. Dose titrations on Days 14, 35, and 60 resulted in mean (SD) Cavg and Cmax for final doses of 10 mg to 70 mg on Day 90 shown in Table 5. The percentages of patients with Cmax greater than 1500 ng/dL, and between 1800 and 2499 ng/dL on Day 90 were 5.4% and 1.6%, respectively. The secondary endpoint was the percentage of patients with Cmax above 3 pre-determined limits. Free thyroid hormone concentrations remain unchanged, however, and there is no clinical evidence of thyroid dysfunction. Edema, with or without congestive heart failure, may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease see ADVERSE REACTIONS. Androgens, including FORTESTA, may promote retention of sodium and water. Long-term therapy with testosterone enanthate has produced multiple hepatic adenomas. However, testosterone levels may be in the normal or subnormal range in men abusing synthetic testosterone derivatives. Testosterone has been subject to abuse, typically at doses higher than recommended for the approved indication and in combination with other anabolic androgenic steroids.
