dexAMETHasone moxifloxacin

Applies to: dexamethasone / moxifloxacin and dexamethasone / moxifloxacin

MONITOR CLOSELY: Concomitant administration of corticosteroids may potentiate the risk of tendinitis and tendon rupture associated with fluoroquinolone treatment. The mechanism is unknown. Tendinitis and tendon rupture have most frequently involved the Achilles tendon, although cases involving the rotator cuff (the shoulder), the hand, the biceps, and the thumb have also been reported. Some have required surgical repair or resulted in prolonged disability. Tendon rupture can occur during or up to several months after completion of fluoroquinolone therapy.

MANAGEMENT: Caution is recommended if fluoroquinolones are prescribed in combination with corticosteroids, particularly in patients with other concomitant risk factors (e.g., age over 60 years; recipient of kidney, heart, and/or lung transplant). Patients should be advised to stop taking the fluoroquinolone, avoid exercise and use of the affected area, and promptly contact their physician if they experience pain, swelling, or inflammation of a tendon. In general, fluoroquinolones should only be used to treat conditions that are proven or strongly suspected to be caused by bacteria and only if the benefits outweigh the risks.

codeine dexAMETHasone

Applies to: anhydrous calcium iodide / codeine and dexamethasone / moxifloxacin

MONITOR: Coadministration of codeine with potent or moderate CYP450 3A4 inducers may result in lower codeine plasma concentrations, higher levels of the inactive metabolite norcodeine, and less metabolism via CYP450 2D6, resulting in lower morphine levels. This interaction may lead to reduced codeine efficacy and potentially initiate the onset of withdrawal symptoms in patients who are physically dependent. In addition, patients may be at an increased risk of CNS and/or respiratory-depressant effects from increased levels of codeine once concomitant therapy with the CYP450 3A4 inducer is ceased. This is particularly worrisome if the CYP450 3A4 inducer also possesses CNS- and/or respiratory-depressant effects. This interaction has also been reported with dihydrocodeine.

MANAGEMENT: The potential loss of efficacy of codeine or dihydrocodeine and onset of opioid withdrawal symptoms should be considered when used in combination with a potent or moderate CYP450 3A4 inducer. Alternative agents with no or minimal CYP450 3A4 induction potential are recommended whenever possible. Some manufacturers of products containing codeine advise against the concomitant use of codeine with CYP450 3A4 inducers. If concomitant use is considered necessary, caution and close clinical and laboratory monitoring are recommended. Dosage adjustments may also be required whenever a CYP450 3A4 inducer is added to or withdrawn from therapy. Following discontinuation of a CYP450 3A4 inducer, patients should be monitored for potentially excessive or prolonged CNS and respiratory depression.

anhydrous calcium iodide moxifloxacin

Applies to: anhydrous calcium iodide / codeine and dexamethasone / moxifloxacin

ADJUST DOSING INTERVAL: Oral preparations that contain magnesium, aluminum, or calcium may significantly decrease the gastrointestinal absorption of quinolone antibiotics. Absorption may also be reduced by sucralfate, which contains aluminum, as well as other polyvalent cations such as iron and zinc. The mechanism is chelation of quinolones by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract. The bioavailability of ciprofloxacin has been reported to decrease by as much as 90% when administered with antacids containing aluminum or magnesium hydroxide.

MANAGEMENT: When coadministration cannot be avoided, quinolone antibiotics should be dosed either 2 to 4 hours before or 4 to 6 hours after polyvalent cation-containing products to minimize the potential for interaction. When coadministered with Suprep Bowel Prep (magnesium/potassium/sodium sulfates), the manufacturer recommends administering fluoroquinolone antibiotics at least 2 hours before and not less than 6 hours after Suprep Bowel Prep to avoid chelation with magnesium. Please consult individual product labeling for specific recommendations.

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

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.
