Interactions between your drugs

Minor

dexAMETHasone ophthalmic exenatide

Applies to: dexamethasone ophthalmic and exenatide

The efficacy of insulin and other antidiabetic agents may be diminished by concomitant use of ophthalmic corticosteroids, particularly during prolonged use. Corticosteroids can raise blood glucose levels by antagonizing the action and suppressing the secretion of insulin, which results in inhibition of peripheral glucose uptake and increased gluconeogenesis. Corticosteroids may interfere with blood glucose control and may cause hyperglycemia, glucose intolerance, new-onset diabetes mellitus, and/or exacerbation of preexisting diabetes. Systemic absorption from use of ophthalmic corticosteroids may occur. Clinical monitoring of glycemic control is recommended if ophthalmic corticosteroids are administered to diabetic patients.

Drug and food interactions

Moderate

exenatide food

Applies to: exenatide

ADJUST DOSING INTERVAL: Exenatide slows gastric emptying and may reduce the extent and rate of absorption of concomitantly administered oral medications. When acetaminophen 1000 mg was administered simultaneously with exenatide 10 mcg and also one hour, 2 hours, and 4 hours after exenatide injection, acetaminophen systemic exposure (AUC) was decreased by 21%, 23%, 24%, and 14%, respectively; peak plasma concentration (Cmax) was decreased by 37%, 56%, 54%, and 41%, respectively; and time to peak plasma concentration (Tmax) was increased from 0.6 hours in the control period to 0.9 hours, 4.2 hours, 3.3 hours, and 1.6 hours, respectively. These values were not significantly changed when acetaminophen was given one hour before exenatide injection.

MANAGEMENT: Concomitantly administered oral medications that are dependent on threshold concentrations for efficacy (e.g., antibiotics, contraceptives) or that require rapid gastrointestinal absorption (e.g., hypnotics, pain medications) should be administered at least 1 hour before exenatide. If such medications are to be administered with food, patients should be advised to take them with a meal or snack when exenatide is not administered.

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.
