Apomorphine HCl

Apomorphine HCl should not be used in individuals with a known hypersensitivity to apomorphine or any of its components. It is also contraindicated in patients who are taking serotonin receptor antagonists (e.g., ondansetron) due to the risk of severe hypotension and loss of consciousness. Patients with severe cardiovascular disease, or those with a history of syncope, should avoid this medication unless closely monitored.

When using Apomorphine HCl, it is important to follow the instructions provided by your healthcare provider for proper administration. The medication is administered via a subcutaneous injection, typically in the abdomen or thigh. Always rotate injection sites to avoid irritation. Nausea is a common side effect, especially when first starting therapy, so your healthcare provider may prescribe an antiemetic (such as trimethobenzamide) to take before each dose. Do not use this medication without first receiving training on how to self-inject, and be sure to monitor for any signs of severe hypotension or allergic reactions. If you experience dizziness, fainting, or severe nausea, contact your healthcare provider immediately.

Common side effects of Apomorphine HCl include nausea, vomiting, dizziness, drowsiness, and injection site reactions (such as redness, swelling, or pain). More serious side effects may include severe hypotension, syncope, hallucinations, or sudden sleep episodes. If you experience any severe reactions, such as loss of consciousness, chest pain, or irregular heartbeats, seek medical attention immediately.

The major risks associated with Apomorphine HCl include the potential for severe hypotension and loss of consciousness, particularly in patients taking other medications that lower blood pressure. There is also a risk of sudden sleep episodes, which can occur without warning. Patients should be cautioned against engaging in activities that require full alertness, such as driving, until they know how the medication affects them. Additionally, apomorphine may cause impulse control disorders (e.g., compulsive gambling or hypersexuality) in some patients. It’s important to discuss these risks with your healthcare provider and to report any unusual behaviors.

Apomorphine HCl may interact with several other medications, including serotonin receptor antagonists (e.g., ondansetron), antihypertensive agents, and central nervous system depressants. These interactions can increase the risk of severe hypotension, drowsiness, and other side effects. Alcohol should be avoided while taking this medication, as it can exacerbate these effects. Always inform your healthcare provider of all medications and supplements you are taking before starting Apomorphine HCl.

Alternative treatments to Apomorphine HCl for managing "off" episodes in Parkinson's disease may include other dopaminergic medications, such as levodopa/carbidopa or dopamine agonists like pramipexole or ropinirole. Depending on the patient’s response to treatment, adjustments to their existing Parkinson's regimen may be considered. For some patients, deep brain stimulation (DBS) or other surgical interventions may also be explored as alternatives.
