Zithromax Drug Interactions (Cont.)

More Detail About Zithromax Interactions

 

Pimozide (Orap)

If you are taking Zithromax with pimozide, your body may metabolize the medicines differently than intended and cause an increase in heart toxicity. You should discuss alternate options with your healthcare provider.
 
Warfarin (Coumadin, Jantoven)
If you are taking Zithromax and warfarin, your body may metabolize the medicines differently than intended. Your healthcare provider may choose to monitor your INR and prothrombin time more frequently and adjust accordingly. INR and prothrombin time are tests used to measure how well you blood is clotting.
 
Aluminum or Magnesium Antacids (Maalox, Mylanta, Riopan, Gelusil, Rolaids, ALternaGEL, Amphojel, and Others)
If you are taking both Zithromax and antacids made with aluminum or magnesium, less of the Zithromax may be absorbed into your body. Be sure to take the antacids at least two hours before or two hours after taking the Zithromax.
 
Other Aluminum/Magnesium Products
If you are taking Zithromax with products or foods containing aluminum or magnesium, your body may metabolize the medicines differently than intended. When taking Zithromax, it is a good idea to allow at least two hours between the time you take your Zithromax dose and when you take any of the aluminum or magnesium products discussed below. Some common products that contain these substances include: supplements, multivitamins with minerals, and laxatives.
 
Digoxin (Digitek, Lanoxicaps, Lanoxin)
If you take Zithromax with digoxin, your body may metabolize the medicines quite differently than intended. You may wish to discuss this with your healthcare provider prior to starting Zithromax.
