Disease interactions

25 potential interactions Applies to: 19 conditions, including High Cholesterol, Underactive Thyroid, Heart Failure, Benign Prostatic Hyperplasia, and Breast Cancer.

Benign Prostatic Hyperplasia

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Benign Prostatic Hyperplasia.

The use of androgenic anabolic steroids is contraindicated for male patients with carcinoma of the breast or prostate. Circulating androgens can be converted in peripheral tissues to estrogens and dihydrotestosterone, which may act as promoters of tumor growth in the breast and prostate, respectively. Likewise, androgenic agents may cause enlargement of the prostate and should be used cautiously in patients with or predisposed to prostatic hypertrophy.

Bleeding Disorder

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Bleeding Disorder.

Androgenic anabolic steroids may cause suppression of clotting factors II, V, VII, and X, and an increase in prothrombin time. Androgen therapy should be administered cautiously in patients with bleeding disorders.

Breast Cancer

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Breast Cancer.

When treated with androgenic anabolic steroids, patients with metastatic breast cancer may develop hypercalcemia due to osteolysis. Frequent determination of urine and serum calcium levels is recommended during therapy with androgenic agents. If hypercalcemia occurs, therapy should be stopped. The development of hypercalcemia may indicate progression of metastases to the bone.

Breast Cancer, Male

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Breast Cancer, Male.

The use of androgenic anabolic steroids is contraindicated for male patients with carcinoma of the breast or prostate. Circulating androgens can be converted in peripheral tissues to estrogens and dihydrotestosterone, which may act as promoters of tumor growth in the breast and prostate, respectively. Likewise, androgenic agents may cause enlargement of the prostate and should be used cautiously in patients with or predisposed to prostatic hypertrophy.

Dermatitis, Drug-Induced

Major:

Viramune

The nevirapine in Viramune has a major potential interaction with Dermatitis, Drug-Induced.

Nevirapine can cause severe, life-threatening skin reactions such as Stevens-Johnson syndrome, toxic epidermal necrolysis, and hypersensitivity reactions characterized by rash, constitutional findings, and organ dysfunction including hepatic failure. Fatalities in association with these reactions have been reported. The first 6 weeks of therapy is the period of greatest risk, and intense monitoring is recommended during the first 18 weeks. In controlled clinical trials, Grade 3 and 4 rashes were reported during the first 6 weeks in 1.5 % of nevirapine-treated patients compared to 0.1% of placebo subjects. Patients who develop signs or symptoms of severe skin reactions or hypersensitivity reactions possibly related to nevirapine at any time during therapy must discontinue the drug and seek medical attention immediately. Because nevirapine-induced hepatitis and hepatic failure may be associated with hypersensitivity reactions, liver function tests should be performed in these patients as well as all patients who develop a rash within the first 18 weeks of treatment. Nevirapine should be permanently discontinued if clinical hepatitis or transaminase elevations combined with rash or other systemic symptoms occur, and should not be restarted after recovery. Nevirapine therapy should also not be restarted following severe skin or hypersensitivity reactions or a rash that is accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, facial edema, eosinophilia, granulocytopenia, lymphadenopathy, or renal dysfunction. During the initial 2-week lead-in period of 200 mg/day (4 mg/kg/day in pediatric patients), the dosage of nevirapine should not be increased if any rash occurs. Dose escalation should only be attempted after the rash resolves.

Diabetes Mellitus

Moderate:

AndroGel

The testosterone in AndroGel has a moderate potential interaction with Diabetes Mellitus.

The metabolic effects of androgenic anabolic steroids may lower blood glucose. Decreased glucose tolerance and increased insulin resistance have also been reported. Patients with diabetes mellitus should be monitored more closely during therapy with androgenic agents, and their antidiabetic regimen adjusted accordingly.

Fluid Retention

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Fluid Retention.

Androgenic anabolic steroids may cause sodium and water retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with fluid overload or are at risk for developing edema. The manufacturers consider the use of androgenic agents to be contraindicated in patients with severe cardiac, renal and/or hepatic dysfunction.

Heart Failure

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Heart Failure.

Androgenic anabolic steroids may cause sodium and water retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with fluid overload or are at risk for developing edema. The manufacturers consider the use of androgenic agents to be contraindicated in patients with severe cardiac, renal and/or hepatic dysfunction.

Hemodialysis

Moderate:

Viramune

The nevirapine in Viramune has a moderate potential interaction with Hemodialysis.

Nevirapine is partially removed by hemodialysis. In a pharmacokinetic study of nevirapine in patients with renal impairment, six subjects requiring hemodialysis exhibited a 44% reduction in nevirapine systemic exposure (AUC) over a one-week period. There was also evidence of accumulation of nevirapine hydroxy-metabolites in plasma in these patients; however, the clinical significance is unknown. A supplemental dose following each dialysis session is indicated for patients undergoing chronic hemodialysis.

High Cholesterol

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with High Cholesterol.

Androgenic anabolic steroids may adversely affect serum lipids, including lowering HDL and elevating LDL levels. These changes can be marked, particularly with the 17-alpha-alkyl derivatives (i.e., fluoxymesterone, methyltestosterone, oxandrolone, oxymetholone, and stanozolol), and may significantly impact the risk of atherosclerosis and coronary artery disease. Patients with preexisting hyperlipoproteinemia may require closer monitoring during therapy with androgenic agents, and adjustments made accordingly in their lipid-lowering regimen. Androgen therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.

Hypercalcemia

Moderate:

AndroGel

The testosterone in AndroGel has a moderate potential interaction with Hypercalcemia.

Androgenic anabolic steroids decrease urinary excretion of calcium, which may result in hypercalcemia. Therapy with androgenic agents should be administered cautiously in patients with hypercalcemia, disorders of bone metabolism such as hyperparathyroidism, or renal dysfunction. Some manufacturers consider the use of androgenic anabolic steroids to be contraindicated in patients with hypercalcemia.

Hyperparathyroidism

Moderate:

AndroGel

The testosterone in AndroGel has a moderate potential interaction with Hyperparathyroidism.

Androgenic anabolic steroids decrease urinary excretion of calcium, which may result in hypercalcemia. Therapy with androgenic agents should be administered cautiously in patients with hypercalcemia, disorders of bone metabolism such as hyperparathyroidism, or renal dysfunction. Some manufacturers consider the use of androgenic anabolic steroids to be contraindicated in patients with hypercalcemia.

Hyperthyroidism

Minor:

AndroGel

The testosterone in AndroGel has a minor potential interaction with Hyperthyroidism.

When androgenic anabolic steroids are used in patients with thyroid disorders, clinicians should be aware that these agents may affect thyroid function tests. Specifically, thyroid-binding globulin levels may be decreased, resulting in lower total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged, however.

Ischemic Heart Disease

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Ischemic Heart Disease.

Androgenic anabolic steroids may adversely affect serum lipids, including lowering HDL and elevating LDL levels. These changes can be marked, particularly with the 17-alpha-alkyl derivatives (i.e., fluoxymesterone, methyltestosterone, oxandrolone, oxymetholone, and stanozolol), and may significantly impact the risk of atherosclerosis and coronary artery disease. Patients with preexisting hyperlipoproteinemia may require closer monitoring during therapy with androgenic agents, and adjustments made accordingly in their lipid-lowering regimen. Androgen therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.

Liver Disease

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Liver Disease.

The use of androgenic anabolic steroids may be associated with development of cholestatic hepatitis and jaundice. Other, more serious hepatotoxicities such as peliosis hepatis and hepatocellular neoplasms are rare but may occur with prolonged use or high dosages. These latter toxicities may be fatal and often not recognized until they become life-threatening. Patients with preexisting liver diseases should be monitored more closely during therapy with anabolic steroids if they are used. If liver function declines or toxicity occurs, therapy should be withdrawn and the cause investigated.

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Liver Disease.

The use of testosterone is contraindicated in patients with serious hepatic or renal disease.

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Liver Disease.

Androgenic anabolic steroids may cause sodium and water retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with fluid overload or are at risk for developing edema. The manufacturers consider the use of androgenic agents to be contraindicated in patients with severe cardiac, renal and/or hepatic dysfunction.

Major:

Viramune

The nevirapine in Viramune has a major potential interaction with Liver Disease.

The use of nevirapine has been associated with severe, life-threatening, and fatal hepatotoxicity, particularly in the first 18 weeks of therapy. Fulminant and cholestatic hepatitis, hepatic necrosis, and hepatic failure have been reported. Nevirapine-induced hepatitis and hepatic failure may be associated with signs of hypersensitivity, which can include severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, facial edema, eosinophilia, granulocytopenia, lymphadenopathy, or renal dysfunction. In controlled clinical trials, symptomatic hepatic events regardless of severity occurred on average in 4% (range 0% to 11%) of patients who received nevirapine and 1.2% of patients in control groups. The risk was greatest in the first 6 weeks of therapy and continued to be greater in the nevirapine groups compared to controls through 18 weeks of treatment. In general, the patients at greatest risk of hepatic events are women with high CD4 counts. During the first 6 weeks of treatment, women have a 3-fold higher risk than men for symptomatic, often rash-associated, hepatic events (5.8% vs. 2.2%). In a retrospective review, women with CD4 counts greater than 250 cells/mm3 had a 12-fold higher risk of symptomatic hepatic events compared to women with lower CD4 counts (11% vs. 0.9%). A 5-fold increased risk was observed in men with CD4 counts greater than 400 cells/mm3 compared to men with lower CD4 counts (6.3% vs. 1.2%). Additionally, coinfection with hepatitis B or C and/or increased liver function tests at the start of therapy are associated with a greater risk of later symptomatic events (6 weeks or more after starting nevirapine) and asymptomatic increases in AST or ALT. Therapy with nevirapine should be administered cautiously in patients with preexisting liver disease or liver function test abnormalities. Due to the risk of drug accumulation, nevirapine should not be administered to patients with severe hepatic impairment. All patients treated with nevirapine should undergo intensive clinical and laboratory monitoring (i.e., once a month or more) during the first 18 weeks of therapy, and regular monitoring thereafter. Liver function tests should be performed at baseline, prior to dose escalation, and at two weeks post-dose escalation. Patients should be instructed to discontinue nevirapine and seek medical attention promptly if signs and symptoms of hepatic injury or hypersensitivity develop such as fever, pruritus, rash, facial edema, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice. Nevirapine should be permanently discontinued if clinical hepatitis or transaminase elevations combined with rash or other systemic symptoms occur, and should not be restarted after recovery. In some cases, hepatic injury progresses despite discontinuation of treatment.

Polycythemia

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Polycythemia.

Androgenic anabolic steroids may cause polycythemia when given in high dosages or for prolonged periods. Patients with preexisting polycythemia may experience worsening of their condition. Frequent monitoring of clinical status and hemoglobin and hematocrit levels is recommended if androgen therapy is administered to these patients.

Prostate Cancer

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Prostate Cancer.

The use of androgenic anabolic steroids is contraindicated for male patients with carcinoma of the breast or prostate. Circulating androgens can be converted in peripheral tissues to estrogens and dihydrotestosterone, which may act as promoters of tumor growth in the breast and prostate, respectively. Likewise, androgenic agents may cause enlargement of the prostate and should be used cautiously in patients with or predisposed to prostatic hypertrophy.

Renal Dysfunction

Major:

AndroGel

The testosterone in AndroGel has a major potential interaction with Renal Dysfunction.

Androgenic anabolic steroids may cause sodium and water retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with fluid overload or are at risk for developing edema. The manufacturers consider the use of androgenic agents to be contraindicated in patients with severe cardiac, renal and/or hepatic dysfunction.
