Staxyn Dosage

General

STAXYN is available in 10 mg orally disintegrating tablets. STAXYN is not interchangeable with vardenafil 10 mg film-coated tablets (LEVITRA). STAXYN provides higher systemic exposure compared to vardenafil 10 mg film-coated tablets (LEVITRA). [See Clinical Pharmacology (12.3).]

STAXYN should be taken orally, as needed, approximately 60 minutes before sexual activity. The maximum dosing frequency is one STAXYN tablet per day. Sexual stimulation is required for a response to treatment.

STAXYN should be placed on the tongue where it will disintegrate. The tablet should be taken without liquid. It should be taken immediately upon removal from the blister.

Those patients who require a lower or higher dose of vardenafil need to be prescribed vardenafil film-coated tablets [see Patient Counseling Information (17)].

Use with Food

STAXYN can be taken with or without food.

Use in Special Populations

Hepatic Impairment: Do not use STAXYN in patients with moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment [see Warnings and Precautions (5.8) and Clinical Pharmacology (12.3)].

Renal Impairment: Do not use STAXYN in patients on renal dialysis [see Warnings and Precautions (5.9) and Clinical Pharmacology (12.3)].

Concomitant Medications

Nitrates: Concomitant use with nitrates in any form is contraindicated [see Contraindications (4.1)].

Guanylate Cyclase (GC) Stimulators, such as riociguat: Concomitant use is contraindicated [see Contraindications (4.2)].

CYP3A4 Inhibitors: Do not use STAXYN with potent or moderate CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, atazanavir, clarithromycin and erythromycin [see Warnings and Precautions (5.2) and Drug Interactions (7.2)].

Alpha-Blockers: In those patients who are stable on alpha-blocker therapy, PDE5 inhibitors should be initiated at the lowest recommended starting dose. Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure in patients taking a phosphodiesterase (PDE5) inhibitor including vardenafil. In patients taking alpha-blockers, do not initiate vardenafil therapy with STAXYN. Lower doses of vardenafil film-coated tablets should be used as initial therapy in these patients. [see Dosage and Administration (2.4)]. Patients taking alpha-blockers who have previously used vardenafil film-coated tablets may change to STAXYN at the advice of their healthcare provider. [See Warnings and Precautions (5.6) and Drug Interactions (7.1).]

A time interval between dosing should be considered when STAXYN is prescribed concomitantly with alpha-blocker therapy [see Clinical Pharmacology (12.2)].
