Drug Interactions

Moderate
Metformin + Abilify

The following applies to the ingredients: Metformin and Aripiprazole (found in Abilify)

MONITOR: The efficacy of insulin and other antidiabetic agents may be diminished by certain drugs, including atypical antipsychotics, corticosteroids, diuretics, estrogens, gonadotropin-releasing hormone agonists, human growth hormone, phenothiazines, progestins, protease inhibitors, sympathomimetic amines, thyroid hormones, L-asparaginase, alpelisib, copanlisib, danazol, diazoxide, isoniazid, megestrol, omacetaxine, phenytoin, sirolimus, tagraxofusp, temsirolimus, as well as pharmacologic dosages of nicotinic acid and adrenocorticotropic agents. These drugs may interfere with blood glucose control because they can cause hyperglycemia, glucose intolerance, new-onset diabetes mellitus, and/or exacerbation of preexisting diabetes.

MANAGEMENT: Caution is advised when drugs that can interfere with glucose metabolism are prescribed to patients with diabetes. Close clinical monitoring of glycemic control is recommended following initiation or discontinuation of these drugs, and the dosages of concomitant antidiabetic agents adjusted as necessary. Patients should be advised to notify their physician if their blood glucose is consistently high or if they experience symptoms of severe hyperglycemia such as excessive thirst and increases in the volume or frequency of urination. Likewise, patients should be observed for hypoglycemia when these drugs are withdrawn from their therapeutic regimen.

Drug and Food Interactions

Major
Metformin + Food

The following applies to the ingredients: Metformin

GENERALLY AVOID: Alcohol can potentiate the effect of metformin on lactate metabolism and increase the risk of lactic acidosis. In addition, alcohol may cause hypoglycemia or hyperglycemia in patients with diabetes. Although hypoglycemia rarely occurs during treatment with metformin alone, the risk may increase with acute consumption of alcohol. Even modest amounts can lower blood sugar significantly, especially when the alcohol is ingested on an empty stomach or following exercise. The mechanism involves inhibition of both gluconeogenesis as well as the counter-regulatory response to hypoglycemia. Episodes of hypoglycemia may last for 8 to 12 hours after ethanol ingestion. By contrast, chronic alcohol abuse can cause impaired glucose tolerance and hyperglycemia. Moderate alcohol consumption generally does not affect blood glucose levels in patients with well controlled diabetes.

Food may have varying effects on the absorption of metformin from immediate-release versus extended-release formulations. When a single 850 mg dose of immediate-release metformin was administered with food, mean peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 40% and 25%, respectively, and time to peak plasma concentration (Tmax) increased by 35 minutes compared to administration under fasting conditions. By contrast, administration of extended-release metformin with food increased AUC by 50% without affecting Cmax or Tmax, and both high- and low-fat meals had the same effect. These data may not be applicable to formulations that contain metformin with other oral antidiabetic agents.

MANAGEMENT: Metformin should be taken with meals, and excessive alcohol intake should be avoided during treatment. Diabetes patients in general should avoid consuming alcohol if their blood glucose is not well controlled, or if they have hypertriglyceridemia, neuropathy, or pancreatitis. Alcohol should not be consumed on an empty stomach or following exercise, as it may increase the risk of hypoglycemia. Patients should contact their physician immediately if they experience potential signs and symptoms of lactic acidosis such as malaise, myalgia, respiratory distress, increasing somnolence, and nonspecific abdominal distress (especially after stabilization of metformin therapy, when gastrointestinal symptoms are uncommon). With more marked acidosis, there may also be associated hypothermia, hypotension, and resistant bradyarrhythmias. Metformin should be withdrawn promptly if lactic acidosis is suspected. Serum electrolytes, ketones, blood glucose, blood pH, lactate levels, and blood metformin levels may be useful in establishing a diagnosis. Lactic acidosis should be suspected in any diabetic patient with metabolic acidosis lacking evidence of ketoacidosis (ketonuria and ketonemia).

Moderate
Abilify + Food

The following applies to the ingredients: Aripiprazole (found in Abilify)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Drug and Pregnancy Interactions

The following applies to the ingredients: Aripiprazole (found in Abilify)

This drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

AU TGA pregnancy category: C
US FDA pregnancy category: Not assigned.

Risk summary: There are insufficient data available on use of this drug in pregnant women to inform a drug-related risk.

Comments:
-A pregnancy exposure registry is available.
-If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential harm to the fetus.
-Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery.

Animal studies have revealed evidence of developmental toxicity, including possible teratogenic effects. Congenital anomalies have been reported; however, a causal relationship has not been established. There are no controlled data in human pregnancy.

There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in neonates exposed to antipsychotic drugs during the third trimester of pregnancy. These complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization.

To monitor the outcomes of pregnant women exposed to atypical antipsychotics, a National Pregnancy Registry for Atypical Antipsychotics has been established. Physicians are encouraged to register patients and pregnant women are encouraged to register themselves. For additional information: http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.

AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Benefit should outweigh risk

AU TGA pregnancy category: C
US FDA pregnancy category: Not assigned

Risk Summary: Data are not sufficient to inform a drug-associated risk for major birth defects or miscarriage; published studies have not reported an increased risk. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy.

Comments:
-Maternal glucose levels should be well controlled prior to conception and throughout pregnancy to avoid maternal and fetal diabetes-associated risks.
-Premenopausal women should understand the potential for unintended pregnancy with use of this drug as ovulation may occur in some anovulatory women.

Animal studies do not indicate harmful effects with respect to pregnancy, embryo or fetal development, birth or postnatal development. Poorly-controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, stillbirth and delivery complications. Poorly controlled maternal diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Published evidence suggests this drug has a good safety profile in women with no increased long-term effects in offspring up to 18 months; however, much of the evidence is from observational, small, and/or nonrandomized studies, and therefore data must be interpreted cautiously.

Many experts continue to recommend insulin as the drug of choice for type 1, type 2, and gestational diabetes when diet alone is unsuccessful in controlling blood sugars. The estimated background risk for major birth defects in women with pre-gestational diabetes mellitus with an HbA1C greater than 7 is 6% to 10% and for women with a HbA1C greater than 10, this risk has been reported to be as high as 20% to 25%. In the US, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The estimated risk of miscarriage for pregnant women with diabetes is unknown. There are no adequate and well-controlled studies in pregnant women.

AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Drug and Breastfeeding Interactions

The following applies to the ingredients: Aripiprazole (found in Abilify)

Use is not recommended; a decision should be made to discontinue breast-feeding or discontinue the drug, taking into account the importance of the drug to the mother.

Excreted into human milk: Yes

Comment: The effects on lactation and in the nursing infant are unknown.

Low levels of this drug have been detected in human milk; the maternal weight-adjusted dose calculated from 2 different women provide estimates of 0.7% and 8.3%. This drug is expected to have a minimal effect on serum prolactin levels, however 2 cases of galactorrhea have been reported.

The following applies to the ingredients: Metformin

Benefit should outweigh risk

Excreted into human milk: Yes

Comments:
-Available data have not reported adverse effects in breastfed infants, however, this data is limited.
-Due to this limited data, product manufacturers recommend a decision should be made to discontinue nursing or discontinue the drug, considering the importance of the drug to the mother.
-Published data suggest this drug is compatible with breastfeeding; they recommend caution when nursing a newborn or premature infant, and those with renal impairment.

Drug levels are expected to be 0.5% (range 0.11% to 1%) of the mother's weight-adjusted dosage and milk/plasma ratio range between 0.13 and 1. Since milk levels are expected to be relatively constant, timing of breastfeeding with drug administration is expected to be of little benefit. One large prospective study found no adverse effects in breastfed infants. Low detectable serum levels were found in some breastfed infants.
