Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Zomepirac may decrease the excretion rate of Abacavir which could result in a higher serum level. Abametapir The serum concentration of Zomepirac can be increased when it is combined with Abametapir. Abciximab The risk or severity of bleeding and hemorrhage can be increased when Zomepirac is combined with Abciximab. Acebutolol Zomepirac may decrease the antihypertensive activities of Acebutolol. Aceclofenac The risk or severity of adverse effects can be increased when Zomepirac is combined with Aceclofenac. Acemetacin The risk or severity of adverse effects can be increased when Zomepirac is combined with Acemetacin. Acenocoumarol The risk or severity of bleeding and hemorrhage can be increased when Zomepirac is combined with Acenocoumarol. Acetaminophen The risk or severity of adverse effects can be increased when Acetaminophen is combined with Zomepirac. Acetohexamide The protein binding of Acetohexamide can be decreased when combined with Zomepirac. Acetylsalicylic acid Zomepirac may decrease the excretion rate of Acetylsalicylic acid which could result in a higher serum level.
