Haloperidol Lactate Inj

Haloperidol Lactate Inj Interactions

Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first.

This drug should not be used with the following medications because very serious interactions may occur:

• cabergoline
• pergolide
• sibutramine
• drugs which may affect the heart rhythm (QTc-prolonging drugs such as bepridil, droperidol, halofantrine, pimozide, sparfloxacin, amiodarone)

Other drugs besides haloperidol and those listed above which may affect the heart rhythm (QTc prolongation in the EKG) include: dofetilide, quinidine, sotalol, procainamide, and erythromycin, among others. Before using haloperidol, report all medications you are currently using to your doctor or pharmacist. QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (e.g., severe dizziness, fainting) that require immediate medical attention. Ask your doctor or pharmacist for more details and for instructions on how you may reduce the risk of this effect.

If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting haloperidol.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of:

• anticholinergic medications (e.g., antispasmodics such as belladonna alkaloids, scopolamine)
• "blood thinners" (e.g., anticoagulants such as warfarin and heparin)
• carbamazepine
• lithium
• methyldopa
• drugs for Parkinson's disease (e.g., levodopa and carbidopa, selegiline)
• quinupristin-dalfopristin
• rifampin
• certain "water pills" (potassium-wasting diuretics such as hydrochlorothiazide, furosemide)

Also report the use of drugs which might increase seizure risk (decrease seizure threshold) when combined with haloperidol such as: bupropion, isoniazid (INH), phenothiazines (e.g., chlorpromazine, fluphenazine, thioridazine), theophylline, tramadol, or tricyclic antidepressants (e.g., amitriptyline, nortriptyline), among others. Consult your pharmacist or doctor for more information.
