Renal Dose Adjustments

No dosage adjustment recommended, because the dose is individually titrated to tolerability.

Moderate to severe renal impairment (glomerular filtration rate less than 50 mL/min): Patients may only be able to tolerate lower doses

Liver Dose Adjustments

-Severe hepatic impairment: Data not available

Dose Adjustments

Interruption of therapy with transdermal patches:
-If dosing interrupted for 3 days or fewer, restart treatment with the same or lower strength transdermal patch.
-If dosing is interrupted for more than 3 days, restart treatment with the 4.6 mg/24 hours transdermal patch and titrate

Dosing Modifications in Patients with Low Body Weight:
-Carefully titrate and monitor patients with low body weight (less than 50 kg) for toxicities (e.g., excessive nausea, vomiting), and consider reducing the dose if such toxicities develop.

If adverse effects (e.g., nausea, vomiting, abdominal pain, loss of appetite) cause intolerance during treatment, the patient should be instructed to discontinue treatment for several doses and then restart at the same or next lower dosage level.

Switching to Patch from Capsules or Oral Solution:
