( 2.2 ) • Assess renal function before starting saxagliptin tablets and periodically thereafter.

Side Effects
6 ADVERSE REACTIONS The following serious adverse reactions are described below or elsewhere in the prescribing information: • Pancreatitis [ see Warnings and Precautions (5.1) ] • Heart Failure [ see Warnings and Precautions (5.2) ] • Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues [ see Warnings and Precautions ( 5.3 ) ] • Hypersensitivity Reactions [ see Warnings and Precautions ( 5.4 ) ] • Severe and disabling arthralgia [ see Warnings and Precautions (5.5) ] • Bullous pemphigoid [ see Warnings and Precautions (5.6) ] • Most common adverse reactions (incidence ≥ 5% and more often than placebo) are upper respiratory tract infection, urinary tract infection, and headache.
Interactions
7 DRUG INTERACTIONS • Strong CYP3A4/5 inhibitors (e.g., ketoconazole): Coadministration with saxagliptin significantly increases saxagliptin concentrations. Limit saxagliptin dosage to 2.5 mg once daily when coadministered with a strong CYP3A4/5 inhibitor. ( 7.1 ) 7.1 Strong Inhibitors of CYP3A4/5 Enzymes Ketoconazole significantly increased saxagliptin exposure. Similar significant increases in plasma concentrations of saxagliptin are anticipated with other strong CYP3A4/5 inhibitors (e.g., atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin). The dosage of saxagliptin should be limited to 2.5 mg when coadministered with a strong CYP3A4/5 inhibitor [ see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ].
Warnings
5 WARNINGS AND PRECAUTIONS • Pancreatitis: There have been postmarketing reports of acute pancreatitis. If pancreatitis is suspected, promptly discontinue saxagliptin. ( 5.1 ) • Heart Failure: Consider the risks and benefits of saxagliptin in patients who have known risk factors for heart failure. Monitor patients for signs and symptoms. ( 5.2 ) • Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues: Consider a lower dosage of insulin or insulin secretagogue when used in combination wtih Saxagliptin tablets ( 5.3 ) • Hypersensitivity-Related Events There have been postmarketing reports of serious hypersensitivity reactions such as anaphylaxis, angioedema, and exfoliative skin conditions. 4 CONTRAINDICATIONS Saxagliptin tablets are contraindicated in patients with a history of a serious hypersensitivity reaction to saxagliptin or any of the ingredients in saxagliptin tablets. Reactions such as anaphylaxis, angioedema, or exfoliative skin conditions have been reported with saxagliptin tablets [ see Warnings and Precautions ( 5.4 ) and Adverse Reactions (6.2) ].
Pregnancy
8.1 Pregnancy Risk Summary Limited data with saxagliptin in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriages. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations] . No adverse developmental effects independent of maternal toxicity were observed when saxagliptin was administered to pregnant rats and rabbits during the period of organogenesis and in pregnant and lactating rats during the pre- and postnatal period [see Data] .
