Specific Drugs That Interfere With Prevacid

Prevacid Drug Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when any of the drugs mentioned above are combined with Prevacid.
 
Ampicillin
Prevacid may decrease the absorption of ampicillin into the body, perhaps making it less effective. Check with your healthcare provider before taking these medications together.
 
Atazanavir
Prevacid may decrease the absorption of atazanavir into the body, making it less effective. For this reason, you should not take Prevacid if you are taking atazanavir.
 
Clopidogrel (Plavix)
Some research suggests that proton-pump inhibitors (PPIs), like Prevacid, may decrease the effectiveness of clopidogrel. This could potentially be a serious drug interaction. However, experts are still in disagreement about how significant this interaction really is and whether it affects all PPIs. Do not combine these medications without discussing the matter with your healthcare provider first.
  
Delavirdine
Prevacid may decrease the level of delavirdine in the blood. In general, this combination should be avoided.
 
Digoxin
Prevacid may decrease the absorption of digoxin into the body. Your healthcare provider may decide to monitor your digoxin levels using a simple blood test, especially when you start or stop taking Prevacid. Prevacid may cause low blood magnesium levels, which can lead to serious arrhythmias (irregular heart rhythms), especially in people taking digoxin. Your healthcare provider may decide to monitor your magnesium levels periodically if you are taking digoxin and Prevacid.
 
Certain Diuretics
Prevacid can cause low blood magnesium (hypomagnesemia). Because certain diuretics can also cause this problem, combining Prevacid with one of these diuretics could cause severely low blood magnesium levels, which may lead to serious side effects such as muscle spasms, irregular heart rhythms, or seizures. Your healthcare provider may decide to monitor your magnesium levels periodically if you are taking Prevacid with one of these diuretics.
  
Erlotinib
Prevacid may decrease the level of erlotinib in the blood. In general, this combination should be avoided.
