Can you take Amrix with Felbamate?

Felbamate has a major potential interaction with Anemia.

The use of felbamate is contraindicated in patients with bone marrow suppression or a current or prior history of blood dyscrasias. A marked increase in the incidence of aplastic anemia has been associated with the use of felbamate, reportedly exceeding 100 times the incidence observed in the general population (2 to 5 per million persons per year). In the few cases that have been reported in felbamate patients, the onset of clinical manifestations of aplastic anemia ranged from 5 to 30 weeks. However, the injury to bone marrow stem cells that is believed to be ultimately responsible for the anemia may occur much earlier. Currently, it is not known whether the risk is related to dose, duration of exposure, and/or concomitant use of other antiepileptic or myelotoxic drugs. Expert hematologic consultation should be available for all patients treated with felbamate. Since aplastic anemia typically develops without premonitory clinical or laboratory signs, it should be borne in mind that routine blood testing may not be reliably used to prevent development of the syndrome. However, in some cases, it may allow the detection of hematologic changes before the condition is full-blown. Felbamate therapy should be withdrawn if evidence of bone marrow depression is observed. Patients who are discontinued from the drug may remain at risk for developing anemia for a variable and unknown period afterwards and should be monitored accordingly.

The cyclobenzaprine in Amrix has a major potential interaction with Cardiovascular Conditions and Disorders.

The manufacturers consider the use of cyclobenzaprine to be contraindicated in the acute recovery phase following myocardial infarction and in patients with hyperthyroidism, congestive heart failure, arrhythmias, heart block, and/or conduction disturbances. Cyclobenzaprine is structurally related to the tricyclic antidepressants, which have been reported to cause tachycardia, arrhythmias, heart block, hypertension, hypotension (particularly orthostatic hypotension), thrombosis, thrombophlebitis, myocardial infarction, strokes, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation. Therapy with cyclobenzaprine should be administered cautiously in patients with a history of cardiovascular or cerebrovascular disease or a predisposition to hypotension, particularly if the intended dosage exceeds those normally used for musculoskeletal conditions. Tachycardia, arrhythmia, palpitation, and hypotension have been reported with the use of cyclobenzaprine in less than 1% of patients.

Felbamate 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 cyclobenzaprine in Amrix has a moderate potential interaction with Gastrointestinal Obstruction.

Cyclobenzaprine has anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with cyclobenzaprine should be administered cautiously in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Glaucoma should be treated and under control prior to initiation of cyclobenzaprine therapy, and intraocular pressure monitored during therapy.

Felbamate has a major potential interaction with Liver Disease.

The use of felbamate is contraindicated in patients with a history of hepatic impairment. A marked increase in the incidence of hepatic failure, some resulting in fatality, has been associated with the use of felbamate relative to that expected in the general population (approximately 2000 cases per year). Currently, it is not known whether the risk is related to dose, duration of exposure, and/or concomitant use of other antiepileptic or hepatotoxic drugs. All patients treated with felbamate should have serum transaminase and bilirubin levels checked prior to initiating therapy and at 1- to 2-week intervals while treatment continues. Felbamate therapy should be withdrawn if abnormal liver function tests occur.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication.

Felbamate has a major potential interaction with Renal Dysfunction.

Felbamate is partially eliminated by the kidney as unchanged drug (approximately 40% to 50% of absorbed dose). The plasma clearance of felbamate may be decreased and the half-life prolonged in patients with impaired renal function. Therapy with felbamate should be administered cautiously in patients with renal impairment.
