Interactions between your drugs

Moderate

glimepiride vadadustat

Applies to: glimepiride / pioglitazone and vadadustat

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with vadadustat, a weak CYP450 2C9 inhibitor, may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of CYP450 2C9. A drug interaction study evaluating the effect of vadadustat (600 mg) on the pharmacokinetics of celecoxib, a CYP450 2C9 substrate, showed an increase in peak plasma concentration (Cmax) and systemic exposure (AUC) by 60% and 11%, respectively.

MANAGEMENT: Some authorities recommend using caution when vadadustat is used in combination with CYP450 2C9 substrates. Monitoring for signs and symptoms of increased exposure to the CYP450 2C9 substrate should be considered whenever vadadustat is added to or withdrawn from therapy. The prescribing information for concomitant medications may be consulted to assess the benefits versus risks of coadministration, as well as any dosage adjustments that may be required during coadministration and/or following the discontinuation of an CYP450 2C9 inhibitor.

Moderate

pioglitazone vadadustat

Applies to: glimepiride / pioglitazone and vadadustat

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with vadadustat may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4 and/or CYP450 2C8 isoenzymes. Vadadustat is an inhibitor of CYP450 3A4 and CYP450 2C8 in vitro. However, clinical data are not available.

MANAGEMENT: Some authorities recommend using caution when vadadustat is used concomitantly with drugs that are substrates of CYP450 3A4 and/or CYP450 2C8, particularly sensitive substrates or those with a narrow therapeutic range. Monitoring for signs and symptoms of increased exposure to the CYP450 3A4 and/or CYP450 2C8 substrate should be considered whenever vadadustat is added to or withdrawn from therapy. The prescribing information for concomitant medications may be consulted to assess the benefits versus risks of coadministration, as well as any dosage adjustments that may be required during coadministration and/or following the discontinuation of a CYP450 3A4 and/or CYP450 2C8 inhibitor.

Drug and food interactions

Moderate

glimepiride food

Applies to: glimepiride / pioglitazone

Alcohol may affect blood glucose levels in patients with diabetes. Both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) may occur, depending on how much and how often you drink. You should avoid using alcohol if your diabetes is not well controlled or if you have high triglycerides, neuropathy (nerve damage), or pancreatitis. Moderate alcohol consumption generally does not affect blood glucose levels if your diabetes is under control. However, it may be best to limit alcohol intake to one drink daily for women and two drinks daily for men (1 drink = 5 oz wine, 12 oz beer, or 1.5 oz distilled spirits) in conjunction with your normal meal plan. Avoid drinking alcohol on an empty stomach or following exercise, as it may increase the risk of hypoglycemia. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

vadadustat food

Applies to: vadadustat

Consumer information for this interaction is not currently available.

MONITOR: Smoking and alcohol consumption during therapy with vadadustat may increase the risk of gastrointestinal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, have been reported during vadadustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.

MANAGEMENT: Caution is advised if vadadustat is prescribed to current tobacco smokers or alcohol drinkers. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
