Major pharmacies currently do not stock flunarizine due to its unregistered status. Patients may need to consider international options for access.

Online Pharmacies and Telehealth E-Prescriptions

Health services offering telehealth consultations can assist in discussing access to flunarizine and alternative treatments. While it may not be readily available, some e-pharmacies may provide international shipping options or generics like flunarizine 10 mg from markets where it's registered.

Mechanism & Pharmacology

Understanding how Flunarizine operates can feel complex, but it's crucial for grasping its benefits and limitations in treatment.

Simplified explanation

Flunarizine acts primarily by blocking calcium channels in the brain. By doing so, it stabilises blood flow and reduces nerve excitability, which can be particularly beneficial for those suffering from migraines and vertigo.

Clinical terms

Pharmacologically, Flunarizine is classified as an antihistamine and a calcium channel blocker. It's indicated for migraine prophylaxis and the management of vertiginous disorders. Its modulation of neurotransmitter release also has implications for managing neurovascular conditions. Understanding these terms can help in discussions with healthcare providers.

Indications & Off-Label Uses

Flunarizine has specific medical applications, although there's ongoing interest in its broader potential.

Approved indications by TGA

In Australia, Flunarizine is generally approved for the prophylaxis of migraine, as well as in the treatment of severe cases of vertigo. Its use is supported by evidence for these indications, although it isn’t widely available.

Off-label uses in Australian clinical practice

Healthcare professionals in Australia sometimes prescribe Flunarizine off-label for conditions like chronic tension-type headaches and in certain cases of epilepsy, particularly where other therapies might fail. Patients may find themselves discussing these options with practitioners if standard treatments aren't effective.

Key Clinical Findings

Recent studies have unveiled interesting insights into the efficacy of Flunarizine.

Between 2022 and 2025, significant research has been conducted both in Australia and abroad. Some studies highlighted its efficacy in reducing migraine frequency and severity. Others noted a potential role in the management of vestibular disorders, further advocating its potential place in treatment paradigms.
