MGA can cause hypogonadism and associated symptoms like diminished secondary sexual characteristics, sexual dysfunction, osteoporosis, and reversible infertility in men and premenopausal women. Combining MGA with an androgen/anabolic steroid like oxandrolone, nandrolone decanoate, or testosterone in men can alleviate MGA-associated symptoms of hypoandrogenism as well as further increase appetite and weight gain. Less common but more serious side effects of MGA include cardiovascular/thromboembolic complications such as thrombophlebitis. It may also cause glucocorticoid side effects such as Cushing syndrome-like symptoms, steroid diabetes, and adrenal insufficiency at high dosages. Case reports of deep vein thrombosis, pulmonary embolism, jaundice, intrahepatic cholestasis, and meningiomas in association with high-dosage MGA have been published. In older patients who take MGA, one in 23 will have an adverse event leading to death. Overdose
MGA has been studied at very high dosages of as much as 1,600 mg/day with no serious adverse effects observed. No clear increase in rate or severity of side effects have been observed up to 1,600 mg/day MGA except for weight gain, mild increases in blood pressure, and some fluid retention. In post-marketing experience, limited reports of overdose have been received. Signs and symptoms described in these reports have included diarrhea, nausea, abdominal pain, shortness of breath, cough, unsteady gait, listlessness, and chest pain. There is no specific antidote for overdose of MGA. Treatment should be supportive and based on symptoms. MGA has not been assessed for dialyzability. However, due to its low solubility, it is thought that dialysis would not be useful for treating MGA overdose.
Periorbital hyperpigmentation, also known as hereditary dark circles, is characterized by darker skin around the eyes caused by the presence of additional melanin. It is an extremely common hereditary human characteristic and is frequently found on individuals with dark skin. Periorbital hyperpigmentation is most prevalent within the 16–25 age group. See also
