Interactions between Insulin isophane and Lithium

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Adrenal Insufficiency.

Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.

Lithium has a major potential interaction with Alcoholism.

Antipsychotics can lower the seizure threshold and trigger seizures in a dose-dependent manner. Seizures have been reported in patients receiving antipsychotic therapy and may occur in epileptic patients even with maintenance of routine anticonvulsant treatment. Therapy with antipsychotics should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. High dosages should be avoided if possible.

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Anorexia/Feeding Problems.

Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Autonomic Neuropathy.

Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.

Lithium has a moderate potential interaction with Breast Cancer.

Antipsychotic drugs can elevate serum prolactin concentrations, and this elevation persists during chronic administration. This should be considered if therapy will be prescribed in patients with previously detected breast cancer as one-third of human breast cancers are prolactin-dependent in vitro. Associated disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported. Appropriate laboratory testing and follow-up is advised.

Lithium has a major potential interaction with Cardiovascular Conditions and Disorders.

Lithium should generally not be given to patients with significant cardiovascular disease since the risk of lithium toxicity is high in these patients. Additionally, there have been postmarketing reports of a possible association between lithium therapy and the unmasking of Brugada Syndrome, a disorder characterized by abnormal EKG findings and a risk of sudden death. Lithium should be avoided in patients with this diagnosis or suspicion of it, or that have risk factors, which include unexplained syncope, family history of this syndrome, or family history of unexplained sudden death before the age of 45 years.
Therapy with lithium should be administered with extreme caution in patients with preexisting cardiac disease. Consultation with a cardiologist is highly recommended and cardiac monitoring should be completed before and during treatment.

Lithium has a major potential interaction with Central Nervous System Disorders.

Antipsychotics can lower the seizure threshold and trigger seizures in a dose-dependent manner. Seizures have been reported in patients receiving antipsychotic therapy and may occur in epileptic patients even with maintenance of routine anticonvulsant treatment. Therapy with antipsychotics should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. High dosages should be avoided if possible.

Lithium has a major potential interaction with Dehydration.

Lithium reduces the ability of the kidney to concentrate urine and produces a mild diabetes insipidus and polyuria. Therefore, patients with preexisting dehydration are more prone to lithium retention and toxicity. Therapy with lithium should be administered cautiously in dehydrated patients and may need to be discontinued until improvement in hydration status. Careful monitoring of lithium levels are recommended. Patients with sweating, diarrhea or concomitant infection with fever may need a temporary reduction or cessation of medication.

Lithium has a major potential interaction with Dementia.

Antipsychotic drugs are not approved for the treatment of patients with dementia-related psychosis. Older patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death; although the causes were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. A causal relationship with antipsychotic use has not been established. In controlled trials in older patients with dementia-related psychosis, patients randomized to risperidone, aripiprazole, and olanzapine had higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, compared to patients treated with placebo.

Lithium has a major potential interaction with Diarrhea.

Lithium reduces the ability of the kidney to concentrate urine and produces a mild diabetes insipidus and polyuria. Therefore, patients with preexisting dehydration are more prone to lithium retention and toxicity. Therapy with lithium should be administered cautiously in dehydrated patients and may need to be discontinued until improvement in hydration status. Careful monitoring of lithium levels are recommended. Patients with sweating, diarrhea or concomitant infection with fever may need a temporary reduction or cessation of medication.

Lithium has a major potential interaction with Diarrhea.

The risk for lithium toxicity may be increased in patients with diarrhea and excessive sweating. Dehydration and sodium depletion may occur in these patients leading to lithium retention and toxicity. The use of lithium may need to be reduced or suspended until the condition resolves. Supplemental fluid and salt may need to be administered. Monitoring serum lithium levels is recommended.

Lithium has a major potential interaction with Fever.

Lithium reduces the ability of the kidney to concentrate urine and produces a mild diabetes insipidus and polyuria. Therefore, patients with preexisting dehydration are more prone to lithium retention and toxicity. Therapy with lithium should be administered cautiously in dehydrated patients and may need to be discontinued until improvement in hydration status. Careful monitoring of lithium levels are recommended. Patients with sweating, diarrhea or concomitant infection with fever may need a temporary reduction or cessation of medication.

Lithium has a moderate potential interaction with Fever.

Patients with fever may have a lower tolerance to lithium due to increased fluid and sodium loss. Lithium dosage may need to be reduced or suspended in such patients. Monitoring lithium serum levels is recommended.

Lithium has a major potential interaction with Hyperhidrosis.

Lithium reduces the ability of the kidney to concentrate urine and produces a mild diabetes insipidus and polyuria. Therefore, patients with preexisting dehydration are more prone to lithium retention and toxicity. Therapy with lithium should be administered cautiously in dehydrated patients and may need to be discontinued until improvement in hydration status. Careful monitoring of lithium levels are recommended. Patients with sweating, diarrhea or concomitant infection with fever may need a temporary reduction or cessation of medication.

Supplemental fluid and salt may need to be administered. Monitoring serum lithium levels is recommended.

Lithium has a moderate potential interaction with Hyperprolactinemia.

Antipsychotic drugs can elevate serum prolactin concentrations, and this elevation persists during chronic administration. This should be considered if therapy will be prescribed in patients with previously detected breast cancer as one-third of human breast cancers are prolactin-dependent in vitro. Associated disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported. Appropriate laboratory testing and follow-up is advised.

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Hypokalemia.

Hypokalemia may commonly occur during treatment with insulin. Use with caution in patients who may be particularly at risk of developing hypokalemia (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations).

Lithium has a major potential interaction with Hyponatremia.

Lithium decreases sodium reabsorption by the renal tubules which could lead to sodium depletion. Therapy with lithium should be administered cautiously in patients with preexisting sodium depletion as the risk of lithium toxicity is increased. Lower dosages may be required. Patients should maintain a normal diet, including salt, and an adequate fluid intake. Monitoring lithium serum concentrations is recommended.

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Liver Disease.

Insulin requirements may be diminished in patients with renal or hepatic impairment due to reduced insulin metabolism and, in the latter case, also to reduced capacity for gluconeogenesis. Lower initial dosages may be appropriate, with careful monitoring of plasma glucose levels and dosing adjustments.

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Malnourishment.

Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.

Lithium has a major potential interaction with Neuroleptic Malignant Syndrome.

Neuroleptic Malignant Syndrome (NMS), a potentially fatal symptom complex, has been reported in association with the use of antipsychotic drugs. The diagnostic evaluation is complicated and the management requires immediate discontinuation of the antipsychotic therapy and intensive symptomatic treatment and medical monitoring. If a patient that has recovered from NMS requires antipsychotic drug treatment again, the reintroduction of therapy should be carefully considered as NMS recurrences have been reported.

Lithium has a moderate potential interaction with Neutropenia.

The use of antipsychotics has been associated with events of leukopenia, neutropenia and agranulocytosis. Possible risk factors include preexisting low white blood cell count, and history of drug induced leukopenia/neutropenia. Patients with these risk factors should have complete blood count monitored frequently during the first few months of therapy. Patients should also be monitored for any signs or symptoms of infection. Treatment should be discontinued in any patient who develops a sore throat, fever, stomatitis, or other signs of infection along with a low WBC count or severe neutropenia (ANC < 1000/mm3).

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Panhypopituitarism.

Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.

Lithium has a major potential interaction with Renal Dysfunction.

Lithium is primarily eliminated by the kidneys and should generally not be administered to patients with significant renal dysfunction. Additionally, morphological changes with glomerular and interstitial fibrosis and nephron atrophy have been reported in patients on chronic lithium therapy, although the association has not been clearly established. Kidney function should be assessed in patients prior to starting therapy, during and thereafter and routine urinalysis and renal function tests are recommended. Progressive or sudden changes in renal function indicate the need for reevaluation of treatment. Monitoring lithium serum levels is also recommended.

The insulin isophane (NPH) in insulin isophane has a moderate potential interaction with Renal Dysfunction.

Insulin requirements may be diminished in patients with renal or hepatic impairment due to reduced insulin metabolism and, in the latter case, also to reduced capacity for gluconeogenesis. Lower initial dosages may be appropriate, with careful monitoring of plasma glucose levels and dosing adjustments.

Lithium has a major potential interaction with Syncope.

Lithium should generally not be given to patients with significant cardiovascular disease since the risk of lithium toxicity is high in these patients. Additionally, there have been postmarketing reports of a possible association between lithium therapy and the unmasking of Brugada Syndrome, a disorder characterized by abnormal EKG findings and a risk of sudden death. Lithium should be avoided in patients with this diagnosis or suspicion of it, or that have risk factors, which include unexplained syncope, family history of this syndrome, or family history of unexplained sudden death before the age of 45 years.
Therapy with lithium should be administered with extreme caution in patients with preexisting cardiac disease. Consultation with a cardiologist is highly recommended and cardiac monitoring should be completed before and during treatment.

Lithium has a major potential interaction with Tachyarrhythmia.

Therapy with lithium should be administered with extreme caution in patients with preexisting cardiac disease. Consultation with a cardiologist is highly recommended and cardiac monitoring should be completed before and during treatment.

Lithium has a major potential interaction with Underactive Thyroid.

The use of lithium has been associated with hypothyroidism in 5% to 15% of patient as it blocks the release of thyroxine (T4) and triiodothyronine (T3) mediated by thyrotropin. Therapy with lithium should be administered cautiously in patients with preexisting hypothyroidism. Careful monitoring of the thyroid function is recommended and supplemental thyroid treatment may be required.
