About XIFAXAN® (rifaximin) 550 mg tablets


Indication for XIFAXAN® 550 mg

XIFAXAN 550 mg is a rifamycin antibacterial indicated for reduction in risk of overt hepatic encephalopathy (HE) recurrence in patients ≥ 18 years of age.

Important Safety Information for XIFAXAN® 550 mg

XIFAXAN (rifaximin) 550 mg tablets are contraindicated in patients with a hypersensitivity to rifaximin, any of the rifamycin antimicrobial agents, or any of the components in XIFAXAN. Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis.

Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon which may lead to overgrowth of C. difficile. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued.

There is increased systemic exposure in patients with more severe hepatic dysfunction. The clinical trials were limited to patients with MELD scores < 25. Therefore, caution should be exercised when administering XIFAXAN to patients with severe hepatic impairment (Child-Pugh C).

Based on animal data, XIFAXAN may cause fetal harm. Discontinue in nursing mothers after taking into account the importance of the drug to the mother.

The most common adverse reactions occurring in ≥ 10% of patients and at a higher incidence than placebo in the clinical study were edema peripheral (15%), nausea (14%), dizziness (13%), fatigue (12%), and ascites (11%).

Xifaxan 550 mg is not available for sale outside the U.S.

Xifaxan 550 mg is licensed by Alfa Wassermann S.p.A. to Salix Pharmaceuticals, Inc.

About APRISO® (mesalamine)

Indication for APRISO® (mesalamine)

APRISO® is a locally-acting aminosalicylate indicated for the maintenance of remission of ulcerative colitis in adults.

Important Safety Information for APRISO® (mesalamine)

APRISO® (mesalamine) extended-release capsules are contraindicated in patients with hypersensitivity to salicylates or aminosalicylates (sulfasalazine), or to any of the components of APRISO capsules.

It is recommended that patients have an evaluation of renal function prior to initiation of APRISO therapy and periodically while on therapy. Exercise caution when using APRISO in patients with known renal dysfunction or a history of renal disease.

Mesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from a flare of inflammatory bowel disease. Symptoms include cramping, acute abdominal pain and bloody diarrhea, sometimes fever, headache, and rash. If acute intolerance syndrome is suspected, promptly discontinue treatment with APRISO.

There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine. Caution should be exercised when administering APRISO to patients with liver disease.

Because dissolution of the coating of APRISO granules depends on pH, APRISO should not be co-administered with antacids. Caution should be taken to closely monitor blood cell counts during mesalamine therapy in patients ages 65 and older. Patients with phenylketonuria should be aware that APRISO contains aspartame, equivalent to 2.24 mg of phenylalanine per day.

The most common treatment-related adverse events occurring in at least 3% of adult patients taking APRISO and at a rate greater than placebo in clinical trials were headache (11%), diarrhea (8%), upper abdominal pain (5%), nausea (4%), nasopharyngitis (4%), influenza and influenza-like illness (4%), and sinusitis (3%).
