Interactions between Equetro and Retifanlimab

The carBAMazepine in Equetro has a moderate potential interaction with Adrenal Insufficiency.

Some anticonvulsants can cause clinically significant hyponatremia (Na < 125 mmol/L). Therapy with these drugs should be administered cautiously in patients with conditions predisposing to hyponatremia, such as SIADH, use of diuretics or drugs associated with inappropriate antidiuretic hormone secretion, adrenal insufficiency, hypothyroidism, primary polydipsia, and edema (e.g., due to liver cirrhosis, congestive heart failure, or nephrotic syndrome). Serum sodium levels should be monitored during maintenance therapy, and patients should be monitored for signs and symptoms possibly indicating hyponatremia such as nausea, malaise, headache, lethargy, confusion, obtundation, and increase in seizure frequency or severity. If hyponatremia occurs, conservative measures such as fluid restriction, a reduction in dosage, or discontinuation of therapy will usually suffice.

The carBAMazepine in Equetro has a moderate potential interaction with Arrhythmia.

Aromatic antiepileptic drugs such as phenytoin, carbamazepine, and oxcarbazepine, inhibit voltage- gated sodium channels and reduce membrane excitability in neurons and muscle and can be associated with cardiovascular effects. Individual agents have demonstrated AV heart block, including second and third-degree block following treatment. This occurred generally, but not solely in patients with underlying EKG abnormalities or risk factors for conduction abnormalities. Therapy with these agents should be considered and administered cautiously in patients with a history of cardiovascular disease and conduction abnormalities.

Retifanlimab has a moderate potential interaction with Autoimmune Disorders.

Programmed death receptor-1/ligand-1 (PD-1/PD-L1) blocking antibodies can cause immune-mediated adverse reactions, which may be severe or fatal. Immune-mediated adverse reactions can occur in any organ system or tissue at any time after starting therapy. This may be considered when using PD-1/PD-L1 blocking antibodies in patients with immune system disorders (e.g., ulcerative colitis, Crohn's disease, lupus) or with conditions affecting the nervous system (e.g., myasthenia gravis, Guillain-Barre syndrome). It is recommended to monitor patients closely for signs/symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions.

The carBAMazepine in Equetro has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

The use of carbamazepine has been associated with hematologic toxicities such as leukopenia, neutropenia, thrombocytopenia and, rarely, aplastic anemia and agranulocytosis. Carbamazepine should not be used in patients with history of bone marrow depression. Complete blood counts, including platelets and possibly reticulocytes and serum iron, should be performed prior to initiating therapy and regularly during therapy. Patients who exhibit decreases in blood counts at any time during treatment should be monitored more closely. Marked depression of blood counts may be indication for permanent withdrawal of carbamazepine therapy.

Retifanlimab has a moderate potential interaction with Bone Marrow Transplantation.

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a programmed death receptor-1/ligand-1 (PD-1/PD-L1) blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT. It is recommended to follow patients closely for evidence of transplant-related complications and intervene promptly. The benefit versus risks of treatment with a PD-1/PD-L1 blocking antibody before or after an allogeneic HSCT should be considered.

The carBAMazepine in Equetro has a moderate potential interaction with Cardiovascular Conditions and Disorders.

Aromatic antiepileptic drugs such as phenytoin, carbamazepine, and oxcarbazepine, inhibit voltage- gated sodium channels and reduce membrane excitability in neurons and muscle and can be associated with cardiovascular effects. Individual agents have demonstrated AV heart block, including second and third-degree block following treatment. This occurred generally, but not solely in patients with underlying EKG abnormalities or risk factors for conduction abnormalities. Therapy with these agents should be considered and administered cautiously in patients with a history of cardiovascular disease and conduction abnormalities.

The carBAMazepine in Equetro has a major potential interaction with Depression.

Antiepileptic drugs can increase depression and suicidal thoughts or behaviors in patients receiving these drugs for any indication. Patients should be monitored for the emergence or worsening of depression, suicidal thoughts and unusual changes in mood or behavior. Caregivers and family should be alert for the emergence or worsening of symptoms. Behaviors of concern should be reported immediately to the healthcare providers.

The carBAMazepine in Equetro has a moderate potential interaction with Depression.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

The carBAMazepine in Equetro has a moderate potential interaction with Fructose Intolerance.

Carbamazepine in chewable tablets and suspension contains sorbitol and should not be administered to patients with rare hereditary problems of fructose intolerance.

The carBAMazepine in Equetro has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Carbamazepine is structurally related to the tricyclic antidepressants and has shown mild anticholinergic activity. Therapy with carbamazepine should be administered cautiously in patients with conditions that may be exacerbated by anticholinergic activity, such as urinary retention or obstruction and elevated intraocular pressure, especially angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma.

The carBAMazepine in Equetro has a moderate potential interaction with Heart Failure.

Some anticonvulsants can cause clinically significant hyponatremia (Na < 125 mmol/L). Therapy with these drugs should be administered cautiously in patients with conditions predisposing to hyponatremia, such as SIADH, use of diuretics or drugs associated with inappropriate antidiuretic hormone secretion, adrenal insufficiency, hypothyroidism, primary polydipsia, and edema (e.g., due to liver cirrhosis, congestive heart failure, or nephrotic syndrome). Serum sodium levels should be monitored during maintenance therapy, and patients should be monitored for signs and symptoms possibly indicating hyponatremia such as nausea, malaise, headache, lethargy, confusion, obtundation, and increase in seizure frequency or severity. If hyponatremia occurs, conservative measures such as fluid restriction, a reduction in dosage, or discontinuation of therapy will usually suffice.

If hyponatremia occurs, conservative measures such as fluid restriction, a reduction in dosage, or discontinuation of therapy will usually suffice.

The carBAMazepine in Equetro has a major potential interaction with Liver Disease.

Most anticonvulsants are primarily metabolized by the liver. Metabolic activity may be decreased in patients with liver disease, resulting in elevated drug levels and increased risk of toxicity. Therapy with anticonvulsants should be administered cautiously in patients with mild and moderate liver impairment. Therapy with these drugs is mostly not recommended in patients with severe liver impairment. Caution is also advised when treating patients with a history of liver disease, since the use of some anticonvulsants has been associated with hepatotoxicity. Baseline and periodic evaluation of liver function is recommended. Therapy should be discontinued and not readministered if evidence of liver damage is observed and felt to be drug-related.

Retifanlimab has a moderate potential interaction with Liver Disease.

No dose adjustment of retifanlimab is recommended for patients with mild hepatic impairment. No clinical studies were conducted with retifanlimab in patients with moderate to severe hepatic impairment. Retifanlimab can cause immune-mediated hepatitis. Monitor liver enzymes at baseline and periodically during treatment. Use caution in patients with hepatic impairment.

Retifanlimab has a moderate potential interaction with Organ Transplant.

Solid organ transplant rejection and other transplant (including corneal graft) rejection have been reported with the use of programmed death receptor-1/ligand-1 (PD-1/PD-L1) blocking antibodies. This may be considered when using PD-1/PD-L1 blocking antibodies in patients who have received a solid organ or other transplant.

The carBAMazepine in Equetro has a major potential interaction with Porphyria.

The use of carbamazepine should be avoided in patients with a history of hepatic porphyria (e.g., acute intermittent porphyria, variegate porphyria, porphyria cutanea tarda). Acute attacks have been reported in such patients receiving carbamazepine therapy.

The carBAMazepine in Equetro has a moderate potential interaction with Psychosis.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

The carBAMazepine in Equetro has a moderate potential interaction with Psychosis.

Carbamazepine is structurally related to the tricyclic antidepressants (TCAs). The possibility of activation of a latent psychosis or exacerbation of psychotic symptoms, especially in elderly patients, should be borne in mind.

The carBAMazepine in Equetro has a major potential interaction with Renal Dysfunction.

Most anticonvulsants are primarily excreted by the kidney. The plasma clearance may be decreased and the half-life prolonged in patients with impaired renal function. Therapy with anticonvulsants should be administered cautiously in patients with significant renal dysfunction. In most cases it is recommended to adjust the dosage in patients with CrCl <50 mL/min to half the usual starting dose and then increase slowly to achieve the desired clinical response. The renal function should be monitored regularly in patients receiving therapy.

The carBAMazepine in Equetro has a moderate potential interaction with Seizures.

Carbamazepine should be used with caution in patients with mixed seizure disorder that includes atypical absence seizures, as in these patients it has been associated with increased frequency of generalized convulsions.

The carBAMazepine in Equetro has a moderate potential interaction with SIADH.

Some anticonvulsants can cause clinically significant hyponatremia (Na < 125 mmol/L). Therapy with these drugs should be administered cautiously in patients with conditions predisposing to hyponatremia, such as SIADH, use of diuretics or drugs associated with inappropriate antidiuretic hormone secretion, adrenal insufficiency, hypothyroidism, primary polydipsia, and edema (e.g., due to liver cirrhosis, congestive heart failure, or nephrotic syndrome). Serum sodium levels should be monitored during maintenance therapy, and patients should be monitored for signs and symptoms possibly indicating hyponatremia such as nausea, malaise, headache, lethargy, confusion, obtundation, and increase in seizure frequency or severity. If hyponatremia occurs, conservative measures such as fluid restriction, a reduction in dosage, or discontinuation of therapy will usually suffice.

The carBAMazepine in Equetro has a moderate potential interaction with Thyroid Disease.

Decreased values for thyroid function tests have been observed with carbamazepine administration. One study reported decreased serum levels of T4, FT4, and T3. In that study, TSH concentrations were not significantly altered. Clinicians should be cognizant of these effects when prescribing or administering carbamazepine therapy to patients with thyroid disorders.

The carBAMazepine in Equetro has a moderate potential interaction with Underactive Thyroid.

Some anticonvulsants can cause clinically significant hyponatremia (Na < 125 mmol/L). Therapy with these drugs should be administered cautiously in patients with conditions predisposing to hyponatremia, such as SIADH, use of diuretics or drugs associated with inappropriate antidiuretic hormone secretion, adrenal insufficiency, hypothyroidism, primary polydipsia, and edema (e.g., due to liver cirrhosis, congestive heart failure, or nephrotic syndrome). Serum sodium levels should be monitored during maintenance therapy, and patients should be monitored for signs and symptoms possibly indicating hyponatremia such as nausea, malaise, headache, lethargy, confusion, obtundation, and increase in seizure frequency or severity. If hyponatremia occurs, conservative measures such as fluid restriction, a reduction in dosage, or discontinuation of therapy will usually suffice.

The carBAMazepine in Equetro has a moderate potential interaction with Urinary Retention.

Carbamazepine is structurally related to the tricyclic antidepressants and has shown mild anticholinergic activity. Therapy with carbamazepine should be administered cautiously in patients with conditions that may be exacerbated by anticholinergic activity, such as urinary retention or obstruction and elevated intraocular pressure, especially angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma.
