Drug Interactions between amiodarone and Proquin XR

Amiodarone may be taken with or without food but should be taken at the same way each time. You should avoid consuming grapefruits and grapefruit juice while taking amiodarone. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor. Grapefruit can raise the levels of amiodarone in your body and lead to dangerous side effects. This can affect the rhythm of your heart. Call your doctor if you have symptoms of irregular heartbeat, chest tightness, blurred vision or nausea.

Do not take ciprofloxacin with dairy products such as milk or yogurt, or with calcium-fortified foods (e.G., cereal, juice). You may eat or drink dairy products or calcium-fortified foods with a regular meal, but do not use them alone when taking ciprofloxacin. They could make the medication less effective. When ciprofloxacin tablets are given with enteral (tube) feedings, ciprofloxacin may not work as well. You could interrupt the feeding for 1 hour before and 2 hours after the ciprofloxacin dose, or your doctor may decide to switch to a different treatment. Ciprofloxacin oral suspension should not be given via nasogastric tubes or feeding tubes. 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.

GENERALLY AVOID: The oral bioavailability of quinolone and tetracycline antibiotics may be reduced by concurrent administration of preparations containing polyvalent cations such as aluminum, calcium, iron, magnesium, and zinc. Therapeutic failure may result. The proposed mechanism is chelation of quinolone and tetracycline antibiotics by di- and trivalent cations, forming an insoluble complex that is poorly absorbed from the gastrointestinal tract. Reduced gastrointestinal absorption of the cations should also be considered.

MANAGEMENT: Concomitant administration of oral quinolone and tetracycline antibiotics with preparations containing aluminum, calcium, iron, magnesium, and/or zinc salts should generally be avoided. Otherwise, the times of administration should be staggered by as much as possible to minimize the potential for interaction. Quinolones should typically be dosed either 2 to 4 hours before or 4 to 6 hours after polyvalent cation preparations, depending on the quinolone and formulation. Likewise, tetracyclines and polyvalent cation preparations should typically be administered 2 to 4 hours apart. The prescribing information for the antibiotic should be consulted for more specific dosing recommendations.

Using caffeine together with ciprofloxacin may increase the effects of caffeine. Contact your doctor if you experience headache, tremor, restlessness, nervousness, insomnia, and increased blood pressure or heart rate. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. 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.
