Interactions between Femtrace and Temsirolimus

The estradiol in Femtrace has a major potential interaction with Abnormal Uterine Bleeding.

The use of estrogens is contraindicated in patients with undiagnosed, abnormal vaginal bleeding. Prolonged (greater than 1 year), unopposed estrogen use (i.e. estrogen without concomitant progestin therapy) has been associated with a significant, dose-related risk of endometrial carcinoma. The risk may be offset substantially by the addition of a progestin but may not be completely abolished. Prior to initiating estrogen therapy, appropriate diagnostic tests should be performed in patients with abnormal vaginal bleeding to rule out endometrial malignancy. The same applies if recurrent or persistent bleeding develops during estrogen therapy.

Temsirolimus has a major potential interaction with Anaphylaxis.

Hypersensitivity/infusion reactions, including but not limited to flushing, chest pain, dyspnea, hypotension, apnea, loss of consciousness, hypersensitivity and anaphylaxis, have been associated with the administration of temsirolimus. Caution should be exercised during the infusion and appropriate supportive care should be available. For patients who develop hypersensitivity reaction during the infusion, it is recommended to stop the infusion and close observation with the possibility of resuming therapy at a slower rate should be contemplated at the discretion of the physician. Temsirolimus infusion should be interrupted in all patients with severe infusion reactions and appropriate medical therapy administered. A benefit-risk assessment should be done prior to the continuation of therapy in patients with severe or life-threatening reactions.

The estradiol in Femtrace has a moderate potential interaction with Angioedema.

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

The estradiol in Femtrace has a moderate potential interaction with Asthma.

Estrogens and progestogens may cause fluid 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 excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

Temsirolimus has a moderate potential interaction with Brain Tumor.

Inhibition of mTOR activity results in delays of wound healing and increases the occurrence of wound-related complications, which might require surgical intervention. Patients with central nervous system tumors (primary CNS tumor or metastases) and/or receiving anticoagulation therapy may be at an increased risk of developing intracerebral bleeding (including fatal outcomes). Caution is recommended when using these agents, particularly in the perioperative period.

The estradiol in Femtrace has a major potential interaction with Breast Cancer.

When treated with an estrogen, patients with breast cancer and bone metastases may develop severe hypercalcemia, in which case the drug should be stopped and measures be taken to reduce serum calcium levels.

The estradiol in Femtrace has a major potential interaction with Cerebral Vascular Disorder.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders. The use of estrogen-containing oral contraceptives is additionally deemed contraindicated in patients with a history of such disorders and/or current cerebrovascular or coronary artery disease. Females with a history of migraines with aura are at an increased risk for stroke and this stroke risk may be further increased in females who have migraines with aura with use of combination oral contraceptives. Hypercoagulability and changes in various clotting factors and blood components have been observed in women receiving estrogen therapy. Known preexisting risk factors for increased thromboembolic or cardiovascular events include smoking, especially over age of 35; hypertension; hyperlipidemia; obesity; diabetes; age over 40; and lupus. Therapy with estrogens should be administered cautiously in the lowest effective dosage and only after careful consideration of risks and benefits. Estrogens should be avoided in patients with a history of thrombotic and thromboembolic disorders associated with estrogen use, except when used in the treatment of metastatic breast or prostatic malignancy.

Temsirolimus has a moderate potential interaction with Coagulation Defects and Disorders.

Inhibition of mTOR activity results in delays of wound healing and increases the occurrence of wound-related complications, which might require surgical intervention. Patients with central nervous system tumors (primary CNS tumor or metastases) and/or receiving anticoagulation therapy may be at an increased risk of developing intracerebral bleeding (including fatal outcomes). Caution is recommended when using these agents, particularly in the perioperative period.

Temsirolimus has a major potential interaction with Dermatitis, Drug-Induced.

Hypersensitivity/infusion reactions, including but not limited to flushing, chest pain, dyspnea, hypotension, apnea, loss of consciousness, hypersensitivity and anaphylaxis, have been associated with the administration of temsirolimus. Caution should be exercised during the infusion and appropriate supportive care should be available. For patients who develop hypersensitivity reaction during the infusion, it is recommended to stop the infusion and close observation with the possibility of resuming therapy at a slower rate should be contemplated at the discretion of the physician. Temsirolimus infusion should be interrupted in all patients with severe infusion reactions and appropriate medical therapy administered. A benefit-risk assessment should be done prior to the continuation of therapy in patients with severe or life-threatening reactions.

The estradiol in Femtrace has a moderate potential interaction with Diabetes Mellitus.

Impaired glucose tolerance has been observed in some patients administered oral contraceptives and appears to be related primarily to the estrogen dose. However, progestogens can increase insulin secretion and produce insulin resistance to varying degrees, depending on the agent. Caution and close monitoring are recommended in patients with diabetes mellitus during therapy with estrogens and/or progestogens, and adjustments made accordingly in their antidiabetic regimen.

Temsirolimus has a moderate potential interaction with Diabetes Mellitus.

Elevations in serum blood glucose levels have been reported in patients taking inhibitors of mTOR (mammalian target of rapamycin). Monitoring of fasting serum glucose levels is recommended prior to the start of therapy and periodically thereafter. Clinicians should achieve control of glucose levels before initiating therapy with these agents.

The estradiol in Femtrace has a moderate potential interaction with Fluid Retention.

Estrogens and progestogens may cause fluid 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 excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The estradiol in Femtrace has a moderate potential interaction with Gallbladder Disease.

A two- to four-fold increase in risk of gallbladder disease has been noted in women receiving postmenopausal estrogen therapy. The risk for gallbladder disease may be less for premenopausal women using oral contraceptives containing low-dose estrogens and/or progestins. Therapy with estrogens should be administered cautiously in patients with preexisting gallbladder disease or a history of pregnancy-related cholestasis.

Temsirolimus has a major potential interaction with Gastrointestinal Perforation.

Cases of fatal bowel perforation occurred in patients who received temsirolimus. Therapy with temsirolimus should be administered with caution in patients who may be at increased risk for gastrointestinal perforation, such as those with a history of diverticulitis. Patients presenting with new onset or worsening of abdominal symptoms or blood in the stools should be evaluated promptly for early identification of gastrointestinal perforation.

The estradiol in Femtrace has a moderate potential interaction with Heart Failure.

Estrogens and progestogens may cause fluid 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 excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The estradiol in Femtrace has a major potential interaction with High Blood Pressure.

The risk of myocardial infarction and strokes, including those associated with oral contraceptive use and some estrogen use, is increased in patients with hypertension. Moreover, estrogens (and progestogens) may elevate blood pressure and worsen the hypertension, thus compounding the risk. Clinically significant blood pressure increases have been reported during estrogen therapy, particularly in patients receiving high dosages or treated with oral contraceptive combinations having high progestational activity. These effects also increase with duration of therapy and patient age. Therapy with estrogens should be administered cautiously in patients with preexisting hypertension. Some estrogen-based therapies, such as combined hormonal contraceptives, may be contraindicated in patients with uncontrolled hypertension or hypertension with vascular disease. Patients should be monitored for changes in cardiovascular status, and their antihypertensive regimen adjusted or estrogen therapy withdrawn as necessary. In patients requiring contraception, alternative methods should be considered for those who are hypertensive, over age 35, and smoke.

The estradiol in Femtrace has a moderate potential interaction with High Cholesterol.

Estrogens may cause adverse lipid changes. Use of estrogens has been associated with elevations in triglyceride levels, particularly in women with pre-existing hypertriglyceridemia. Discontinue therapy if elevated triglycerides lead to pancreatitis. Manage hypercholesterolemia appropriately as indicated.

Temsirolimus has a moderate potential interaction with High Cholesterol.

Elevations in cholesterol and triglyceride levels have been reported in patients taking inhibitors of mTOR (mammalian target of rapamycin). Monitoring of fasting lipid profile is recommended prior to the start of therapy and periodically thereafter.

The estradiol in Femtrace has a moderate potential interaction with Hypoparathyroidism.

Estrogens should be used with caution in individuals with severe hypocalcemia or hypoparathyroidism. Estrogen-induced hypocalcemia may occur in patients with hypoparathyroidism; consider whether the benefits of estrogen therapy outweigh the risks.

Temsirolimus has a moderate potential interaction with Infection.

The immunosuppressant effect of inhibitors of mTOR (mammalian target of rapamycin) may decrease host resistance to infectious agents and may predispose patients to bacterial, fungal, viral, or protozoal infections, infections with opportunistic pathogens, and reactivation of viral infections. Therapy with these agents should be administered with caution in patients with an infection, particularly active infections or any untreated systemic fungal, bacterial, parasitic, or viral infection. It is recommended to complete the treatment of preexisting invasive fungal infections prior to starting treatment and if a diagnosis of invasive systemic fungal infection is made during treatment, discontinue and treat with appropriate antifungal therapy.

Temsirolimus has a moderate potential interaction with Interstitial Lung Disease.

Cases of interstitial lung disease, some resulting in death, occurred in patients who received temsirolimus. It is recommended that patients undergo baseline radiographic assessment by lung computed tomography scan or chest radiograph prior to the initiation of therapy. Close monitoring for the occurrence of any new or worsening respiratory symptoms is advisable and if clinically significant respiratory symptoms develop, consider withholding administration until after recovery of symptoms and improvement of radiographic findings related to pneumonitis.

The estradiol in Femtrace has a major potential interaction with Ischemic Heart Disease.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders.

Temsirolimus has a major potential interaction with Liver Disease.

Temsirolimus is contraindicated in patients with bilirubin >1.5×ULN. Caution is recommended when treating patients with mild hepatic impairment and a dose reduction may be needed depending on AST and bilirubin levels. Dosage adjustment is needed based on hepatic function; therefore, assessment of AST and bilirubin levels is recommended before initiation of therapy and periodically thereafter.

The estradiol in Femtrace has a moderate potential interaction with Liver Disease.

Estrogens are primarily metabolized by the liver. Use of estrogen therapy is contraindicated in patients with liver dysfunction or disease. Patients with impaired hepatic function may be at increased risk for adverse effects associated with estrogen administration due to decreased drug clearance. Patients with hepatic hemangiomas are at increased risk of exacerbation with use of estrogens. Therapy with estrogens should be administered cautiously in patients with cholestatic jaundice associated with past estrogen use or with pregnancy. In addition, clinicians should be aware that estrogen therapy may affect liver function tests.

The estradiol in Femtrace has a major potential interaction with Migraine.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders.

The estradiol in Femtrace has a major potential interaction with Neoplasia, Estrogen Dependent.

The use of estrogens is generally contraindicated in patients with known or suspected estrogen-dependent neoplasia such as breast and endometrial cancer, since it may stimulate tumor proliferation. High dosages of estrogens may be used for the palliative treatment of inoperable, metastatic breast cancer, but only in appropriately selected men and postmenopausal women.

The estradiol in Femtrace has a moderate potential interaction with Pancreatitis.

Estrogens may cause adverse lipid changes. Use of estrogens has been associated with elevations in triglyceride levels, particularly in women with pre-existing hypertriglyceridemia. Discontinue therapy if elevated triglycerides lead to pancreatitis. Manage hypercholesterolemia appropriately as indicated.

Temsirolimus has a moderate potential interaction with Pulmonary Impairment.

Cases of interstitial lung disease, some resulting in death, occurred in patients who received temsirolimus. It is recommended that patients undergo baseline radiographic assessment by lung computed tomography scan or chest radiograph prior to the initiation of therapy. Close monitoring for the occurrence of any new or worsening respiratory symptoms is advisable and if clinically significant respiratory symptoms develop, consider withholding administration until after recovery of symptoms and improvement of radiographic findings related to pneumonitis.

Temsirolimus has a major potential interaction with Renal Dysfunction.

Cases of renal failure, including acute renal failure and elevations of serum creatinine and proteinuria, some with a fatal outcome, have been observed in patients treated with inhibitors of mTOR (mammalian target of rapamycin). Therapy with these agents should be administered cautiously in patients with renal dysfunction, in particularly where patients have additional risk factors that may further impair renal function. Renal impairment is not expected to influence drug exposure, and no dosage adjustment is recommended in patients with renal impairment. Monitoring of renal function, including measurement of blood urea nitrogen (BUN), urinary protein, or serum creatinine, is recommended prior to the start of therapy and periodically thereafter.

The estradiol in Femtrace has a moderate potential interaction with Renal Dysfunction.

Estrogens and progestogens may cause fluid 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 excess fluid.

Estrogens should be avoided in patients with a history of thrombotic and thromboembolic disorders associated with estrogen use, except when used in the treatment of metastatic breast or prostatic malignancy.

The estradiol in Femtrace has a moderate potential interaction with Thyroid Disease.

When administering estrogen and/or progestogen therapy in patients with thyroid disorders, clinicians should be aware that these hormones may affect thyroid function tests. Patients on thyroid replacement therapy may require higher doses of thyroid hormone and appropriate monitoring. Changes have mostly been reported with the use of combination oral contraceptives. Specifically, thyroid-binding globulin (TBG) may be increased, resulting in elevated circulating total thyroid hormone, as measured by PBI (protein-bound iodine), T4 by column or radioimmunoassay, or T3 by radioimmunoassay. Free T3 resin uptake may be decreased. On the contrary, a decrease in TBG and, consequently, thyroxine concentration, has been reported by the manufacturers of the progestin-only (norethindrone) oral contraceptives.

Temsirolimus has a major potential interaction with Vaccination.

The administration of live vaccines should be avoided during therapy with inhibitor of mTOR (mammalian target of rapamycin). It is recommended that close contact with individuals who have received live vaccines should be avoided because of the potential risk for shedding from the household contact and transmission to patient. It is recommended to be up-to-date with all required immunizations, as recommended by current immunization guidelines, before initiating therapy with these agents.
