Zyloprim Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when Zyloprim is combined with any of the drugs listed above.
There have been reports indicating that ACE inhibitors may increase the risk of dangerous reactions to Zyloprim, although this is not known for certain. Check with your healthcare provider before taking Zyloprim with an ACE inhibitor.
Amoxicillin or Ampicillin
Combining Zyloprim with amoxicillin or ampicillin may increase the risk of skin rashes (including very dangerous skin reactions). Check with your healthcare provider before taking these medications together.
There have been reports indicating that antacids may decrease the absorption of Zyloprim into the body. It is probably a good idea to take antacids and Zyloprim at different times of the day, if possible.
If you take Zyloprim with azathioprine, your dose of azathioprine must be reduced significantly, in order to prevent serious side effects of azathioprine.
Zyloprim can increase the level of chlorpropamide in your blood, increasing your risk of low blood sugar (hypoglycemia). You may need to monitor your blood sugar more closely when starting or stopping Zyloprim (or even when changing your dose).
Zyloprim may increase the toxic effects of cyclophosphamide. Check with your healthcare provider before taking these medications together.
Zyloprim may increase the level of cyclosporine in the blood, increasing the risk of side effects. Your healthcare provider should measure the level of cyclosporine in your blood (using a blood test) when you start or stop Zyloprim (or even when you change your Zyloprim dose).
