Can you take Iophen DM NR with Tolcapone?

Tolcapone has a moderate potential interaction with Hypotension.

Dopamine agonists may impair the systemic regulation of blood pressure, with resultant orthostatic hypotension at any time, but especially during dose escalation. Additionally, patients with Parkinson's disease may have an impaired capacity to respond to an orthostatic challenge. For these reasons, patients with Parkinson's disease (or restless legs syndrome) who are being treated with dopaminergic agonists typically require careful monitoring for signs/symptoms of orthostatic hypotension, especially during dose escalation, and should be advised of this risk.

Tolcapone has a moderate potential interaction with Hypotension.

Tolcapone-enhanced bioavailability of levodopa can induce orthostatic hypotension and/or syncope. Adjunct therapy with tolcapone should be administered cautiously in patients with, predisposed to, or adversely affects by hypotension and/or syncope.

Tolcapone has a moderate potential interaction with Liver Disease.

Transaminase (AST/ALT) levels >3 times (occasionally 8 times) the upper limits of normal have occurred in 1% to 3% of patients administered tolcapone, depending on the dosage. Approximately 1/3 of these patients also developed diarrhea. Tolcapone is extensively metabolized by the liver to inactive forms and < 0.5% is eliminated unchanged by the kidney. A 50% reduction in clearance and volume of distribution has occurred in patients with moderate liver cirrhosis, resulting in a 2 fold increase in concentration of unbound tolcapone. Therapy with tolcapone should be administered cautiously in patients with compromised hepatic function. Clinical monitoring of hepatic function is recommended prior to initiation of tolcapone, monthly during the first 3 months, and every 6 weeks for the next 3 months of therapy.

Tolcapone has a moderate potential interaction with Psychosis.

Reversible hallucinations have occurred (usually within the first 2 weeks of therapy) in patients receiving tolcapone. Confusion, occasional insomnia, and excessive dreaming commonly accompany the hallucinations. Therapy with tolcapone should be administered cautiously in patients with or predisposed to psychoses or emotional disorders. Reducing the levodopa dosage may result in resolution of hallucinations. Clinical monitoring of mental status is recommended.

Tolcapone has a moderate potential interaction with Psychosis.

Ordinarily, patients with major psychotic disorder should not be treated with dopaminergic antiparkinsonian agents, because of the risk of exacerbating psychosis. Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson's disease and may decrease the effectiveness of these drugs. The use of bromocriptine in patients with severe psychotic disorders is not recommended.

Tolcapone has a moderate potential interaction with Renal Dysfunction.

Approximately 60% of tolcapone is eliminated by the kidney and < 0.5% is excreted unchanged in the urine. Dosage modification is not indicated for patients with mild to moderate renal impairment. The pharmacokinetic disposition of tolcapone has not been determined in patients with severe renal impairment and tolcapone should be administered cautiously in these patients.

Tolcapone has a moderate potential interaction with Syncope.

Tolcapone-enhanced bioavailability of levodopa can induce orthostatic hypotension and/or syncope. Adjunct therapy with tolcapone should be administered cautiously in patients with, predisposed to, or adversely affects by hypotension and/or syncope.
