PRESCRIPTION: Yes

GENERIC: Yes

PREPARATIONS: Delayed-release capsules: 20, 30 and 60 mg

STORAGE: Capsules should be stored at room temperature, between 15 C to 30 C (59 F to 86 F).

PRESCRIBED FOR: Duloxetine is used for the treatment of depression, generalized anxiety disorder, pain associated with diabetic peripheral neuropathy, fibromyalgia, and chronic musculoskeletal pain.

DOSING:

The recommended dose for treating depression is 20 or 30 mg twice daily or 60 mg once daily. Patients may be started with 30 mg once daily for one week before the dose is advanced to 60 mg daily.

The recommended dose for anxiety disorder, pain associated with diabetic neuropathy, fibromyalgia, or chronic musculoskeletal pain is 60 mg daily. Starting at 30 mg daily for one week before increasing to 60 mg daily may help patients adjust to the drug. There is no evidence that doses greater than 60 mg/day provide additional benefits. However, the maximum dose for depression or anxiety disorder is 120 mg/day.

DRUG INTERACTIONS: Duloxetine should not be used in combination with a monoamine oxidase inhibitor (MAOI) such as phenelzine (Nardil), tranylcypromine (Parnate), isocarboxazid (Marplan), and selegiline (Eldepryl), or within 14 days of discontinuing the MAOI. At least 5 days should be allowed after stopping duloxetine before starting an MAOI. Combinations of SNRIs and MAOIs may lead to serious, sometimes fatal, reactions including very high body temperature, muscle rigidity, rapid fluctuations of heart rate and blood pressure, extreme agitation progressing to delirium, and coma. Similar reactions may occur if duloxetine is combined with antipsychotics, tricyclic antidepressants or other drugs that affect serotonin in the brain. Examples include tryptophan, sumatriptan (Imitrex), lithium, linezolid (Zyvox), tramadol (Ultram), and St. John's Wort.
