Does Apomorphine Interact with Apomorphine Hydrochloride?
CDI records a contraindicated classification for Apomorphine and Apomorphine Hydrochloride. The stored summary is: 7 DRUG INTERACTIONS Concomitant use of antihypertensive medications and vasodilators: increased risk for hypotension, myocardial infarction, pneumonia, falls, and injuries ( 7.2 ) Dopamine antagonists such as neuroleptics or metoclopramide, may diminish the effectiveness of apomorphine hydrocloride ( 7.4 ) 7.1 5HT 3 Antagonists Based on reports of profound hypotension and loss of consciousness when apomorphine hydrocloride was administered with ondansetron, the concomitant use of apomorphine hydrocloride with 5HT 3 antagonists including antiemetics (for example, ondansetron, granisetron, dolasetron, palonosetron) and alosetron, is contraindicated. Concomitant administration of 0.4 mg sublingual nitroglycerin with apomorphine hydrocloride in healthy subjects causes greater decreases in blood pressure compared to apomorphine hydrocloride alone. When nitroglycerin and apomorphine hydrocloride were concomitantly administered to healthy subjects, the mean largest decrease (the mean of each subject's largest drop in blood pressure measured within the 6-hour period following administration of apomorphine hydrocloride) in supine systolic and diastolic blood pressure (measured over 6 hours) was 9.7 mm Hg and 9.3 mm Hg, respectively [see Clinical Pharmacology (12.3) ]. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

What To Tell Your Doctor or Pharmacist
If you are taking Apomorphine and your doctor is considering prescribing Apomorphine Hydrochloride (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Ask about alternative medications that do not interact with your current regimen
- Ask how frequently you should be monitored while these are co-prescribed
- Never stop or change either medication without first consulting your healthcare provider
