Delipid Gemfibrozil Loperamide + Simethicone
ModerateGemfibrozil blocks CYP2C8, an enzyme in the liver that helps clear loperamide from the body. In the same study, taking gemfibrozil raised the loperamide level in the blood by about 2 fold. When itraconazole and gemfibrozil were taken together, the peak loperamide level rose 4 fold. The total amount of loperamide in the blood over time rose 13 fold. Even with these rises, there were no effects on the central nervous system (CNS). Tests of mental and physical response showed no change. These included how drowsy people said they felt and the Digit Symbol Substitution Test.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
