These challenges vary from person to person, with some finding the benefits outweigh the negatives. It is crucial for patients to communicate openly with healthcare providers to tailor their treatment effectively.

Product Overview & Brand Variants

Flunarizine is recognized as a valuable treatment option in Canada, marketed primarily under the brand name Sibelium®. Available strengths in Canada include both 5 mg and 10 mg tablets, appealing to diverse patient needs. Regulatory standards classify Flunarizine as a prescription-only medication, emphasizing the importance of healthcare oversight in its dispensing.

Legal Classification Under Health Canada

Flunarizine is categorized as prescription-only in Canada, ensuring it is used appropriately within the healthcare system. This classification necessitates a healthcare provider's guidance to help manage the potential side effects and ensure patient safety.

Indications in Local Canadian Medical Practice

Flunarizine is approved in Canada primarily for migraine prophylaxis and as a treatment option for vertigo. The Health Canada Drug Identification Number (DIN) supports its legitimacy as a therapeutic agent, allowing patients to trust its efficacy in clinical settings.

Off-Label Patterns in Canadian Healthcare

While Flunarizine is primarily used for migraine and vertigo, some healthcare practitioners may prescribe it off-label for conditions such as anxiety and depression. This practice, while not standard, indicates the medication's versatility and highlights the importance of clinician discretion in treatment plans.

How It Works in the Body

Flunarizine operates by blocking calcium channels, aiding in stabilizing neural activity and preventing migraine attacks. This mechanism makes it effective for both migraine prevention and managing 'dizziness' associated with vestibular disorders.

Clinical Detail from Health Canada Resources

From clinical evidence, Flunarizine is linked to reductions in the frequency of migraines and is especially helpful for those who have not responded to traditional treatments, such as beta-blockers. Studies highlight its safety profile, although monitoring for potential mood changes and extrapyramidal symptoms is advised.

Dosage & Administration

According to Canadian guidelines, the standard regimen for Flunarizine typically begins with a daily dose of 10 mg at bedtime, potentially reduced to 5 mg for elderly patients. Health professionals recommend a review of treatment after 2-3 months of use, especially in migraine management.

Adjustments by Patient Type

In considerations of tailoring Flunarizine dosages, healthcare providers may need to adjust for various patient demographics. For instance, elderly patients or those with hepatic impairment may require lower dosages to minimize side effects. Close monitoring is essential to ensure optimal therapeutic outcomes for all patients.

Contraindications & Side Effects

Common (Health Canada-approved list)

Flunarizine, known for its effectiveness in treating migraines and certain vertigo disorders, comes with a range of commonly reported side effects as deemed by Health Canada. Patients often experience:

• Drowsiness
• Weight gain
• Increased appetite
• Nasal congestion

Moderate side effects can also occur, including fatigue, depression symptoms, and gastrointestinal upset. Importantly, specific contraindications exist: individuals with a history of depressive illness, Parkinson’s disease, severe hepatic insufficiency, or known hypersensitivity to flunarizine should avoid this medication. Caution is warranted in the elderly or those with mildly impaired liver function or concurrent use of CNS depressants.

Rare but serious (with Canadian pharmacovigilance data)

Despite its overall safety, rare instances of severe side effects have been reported through Canadian pharmacovigilance. These include significant extrapyramidal symptoms such as tremors and rigidity, particularly in elderly patients or those on prolonged therapy. There is also an associated risk of lowering the seizure threshold, with rare cases of seizures noted in predisposed individuals. Patient reports emphasize the need for monitoring, especially during extended use, as the balance between benefits and risks can shift.

Regulatory Status

Health Canada approval process

Flunarizine underwent a rigorous Health Canada approval process before it became available as a prescription medication. The safety profile was assessed through several clinical trials, with emphasis on its efficacy as a preventer of migraines and its role in treating vertigo. Regulatory challenges involved ensuring its side effects were clearly communicated to patients through comprehensive labelling requirements. Today, flunarizine is recognized as a controlled substance, requiring a prescription to ensure safe usage.

DIN number relevance

Every prescription drug in Canada, including flunarizine, is assigned a Drug Identification Number (DIN). This unique identifier is crucial for tracking medications within the healthcare system. A DIN verifies the drug's formulation, labelling, and marketing approval, ensuring safety and efficacy for patients. Knowing the DIN is invaluable for healthcare professionals and patients alike as it allows for streamlined communication regarding medications.
