Cymbalta Online - Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking duloxetine, it is especially important that your doctor and pharmacist know if you are taking any of the following:

• Antidepressants (fluoxetine [e.g., Prozac], paroxetine [e.g., Paxil])—Taking certain medicines for depression with duloxetine may increase your chance for side effects.
• Antiarrhythmics (flecainide [e.g., Tambocor], propafenone [e.g., Rythmol], Quinidine [e.g., Quinaglute, Quinidex])—Taking certain medicines for an uneven heartbeat together with duloxetine may increase the chance of getting serious side effects.

At least 14 days should be allowed between stopping treatment with one medicine (duloxetine or the MAO inhibitor) and starting treatment with the other
• Phenothiazines (e.g., Compazine, Phenergan, Thorazine)—Taking phenothiazines together with duloxetine may increase the risk of side effects.
