WARNING: SERIOUS INFECTIONS and MALIGNANCY. SERIOUS INFECTIONS: Patients treated with adalimumab are at increased risk for serious infections leading to hospitalization or death, including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as histoplasmosis), and infections due to other opportunistic pathogens. Discontinue adalimumab if a serious infection develops. MALIGNANCY: Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers including adalimumab.
Hypoglycemia: Acarbose does not cause hypoglycemia when used alone, but may increase risk when combined with sulfonylureas or insulin. Hypoglycemic episodes should be treated with glucose (dextrose), not sucrose.,Hepatic injury: Rare cases of acute hepatitis, jaundice, and fulminant hepatic failure; monitor liver function tests.,Renal impairment: Contraindicated in patients with Cr Cl <25 m L/min.,Gastrointestinal effects: Frequently causes flatulence, diarrhea, and abdominal discomfort due to undigested carbohydrates; these effects may diminish with continued use.
Serious infections including tuberculosis, invasive fungal infections, and other opportunistic pathogens,Hepatitis B virus reactivation,Hypersensitivity reactions including anaphylaxis and angioneurotic edema,Neurologic events including new onset or exacerbation of demyelinating disorders,Hematologic events including pancytopenia and aplastic anemia,Congestive heart failure,Lupus-like syndrome,Malignancies including lymphoma, leukemia, and other malignancies
Hypersensitivity to acarbose or any component,Diabetic ketoacidosis,Cirrhosis,Inflammatory bowel disease,Colonic ulceration,Partial intestinal obstruction or predisposition to intestinal obstruction,Chronic intestinal diseases associated with marked disorders of digestion or absorption,Conditions that may deteriorate as a result of increased intestinal gas formation (e.g., Roemheld syndrome),Severe renal impairment (Cr Cl <25 m L/min)
Known hypersensitivity to adalimumab or any inactive component of the product,Active serious infections including sepsis, tuberculosis, and opportunistic infections
Avoid sucrose and table sugar as they may worsen GI side effects. Dietary carbohydrates increase efficacy but also GI side effects. Precose alone does not cause hypoglycemia; however, if used with insulin or sulfonylureas, hypoglycemia must be treated with glucose (dextrose) because absorption of complex sugars and sucrose is inhibited.
No significant food interactions. Grapefruit and other CYP450 modulators do not affect adalimumab. Take without regard to meals.
Pregnancy Category B. No evidence of teratogenicity in animal studies at doses up to 200 mg/kg/day (6-15 times human exposure). No adequate human studies; risk cannot be ruled out.
Abrilada (adalimumab-adbm) is a TNF-alpha inhibitor. Limited human data; animal studies show no evidence of teratogenicity. Potential risk of increased infection in neonates exposed in utero. First trimester: Minimal known risk. Second/third trimester: May cross placenta; theoretical risk of immunosuppression.
Unknown if excreted in human milk. Caution advised. M/P ratio not established.
Excreted in human milk in low concentrations; M/P ratio not well defined. Considered compatible with breastfeeding, but monitor infant for infection risks.
No dose adjustment recommended; monitor glucose control closely as pharmacokinetics may change; insulin often preferred.
No dose adjustment routinely required; pregnancy may increase clearance, but no established guidelines for dose modification.
Precose (acarbose) is an alpha-glucosidase inhibitor that delays carbohydrate absorption. It is most effective for postprandial hyperglycemia. Must be taken with the first bite of each main meal. Avoid use in patients with inflammatory bowel disease, colonic ulceration, or partial intestinal obstruction. Can cause elevated liver enzymes; monitor LFTs every 3 months during first year. Hypoglycemia from other agents should be treated with glucose (not sucrose) because sucrase is inhibited.
ABRILADA (adalimumab) is a TNF-alpha inhibitor. Monitor for latent TB reactivation with PPD or IGRA before initiation. Injection site reactions are common; rotate sites and apply cold compresses. Avoid live vaccines during therapy. Assess for new-onset or worsening heart failure, demyelinating disorders, and cytopenias. Increased risk of serious infections; screen for HBV, HCV, and fungal infections. Consider temporarily holding therapy for major surgical procedures.
