Frequently Asked Questions

What are the key facts about BOTOX® and Chronic Migraine?

Chronic migraine is defined as experiencing 15 or more headache days per month, with at least 8 days showing migraine characteristics. Since its approval in Canada in 2011, BOTOX® has helped over a million people manage chronic migraine worldwide. At Chinook Medical Centre, treatments typically take about 10 to 15 minutes and are offered every 12 weeks. Dosing may be optimized between 155 to 195 units based on individual patient needs and the PREEMPT protocol.

BOTOX® (onabotulinumtoxinA) is a purified protein derived from natural sources and is a Health Canada–approved preventive treatment specifically for chronic migraine. Unlike acute medications that treat symptoms after a migraine starts, BOTOX® works preventively by blocking nerve signals that trigger migraine attacks, helping to reduce headache frequency and severity.

BOTOX® is one of the few preventive therapies specifically approved for chronic migraine and is administered every 12 weeks. It has been shown to reduce headache days by an average of 8 to 9 days per month. Treatments are done safely in clinic settings like Chinook Medical Centre, where dosing can be personalized—starting with 31 injections (155 units) and, if needed, up to 40 additional units for pain areas including the trapezius muscles.

If you experience chronic migraine with 15 or more headache days per month, preventive treatment such as BOTOX® may be suitable. Many patients with episodic migraine may also require preventive therapy depending on the severity, disability, and impact on quality of life. Consult a physician at Chinook Medical Centre to determine if BOTOX® is right for your individual needs.

A typical treatment session lasts about 10 to 15 minutes and involves 31 small injections across 7 muscle areas in the head, neck, shoulders, and trapezius muscles. Injections use a fine needle and patients often describe them as mild pinpricks. Treatment is performed at Chinook Medical Centre, starting with at least 3 treatment cycles spaced 12 weeks apart to properly evaluate effectiveness, followed by maintenance treatments every 12 weeks.

During your appointment, a trained healthcare professional will deliver the injections targeting migraine-related muscles, including additional areas as needed following the “follow the pain” protocol. Most patients report the injections feel like minor pinpricks, and you can resume daily activities immediately after.

Injections use fine needles placed just under the skin into shallow muscles. The procedure is quick and generally well tolerated. Chinook Medical Centre ensures a comfortable and professional experience.

Yes. Acute medications can be taken alongside BOTOX® if recommended by your healthcare provider, to manage migraine attacks that occur despite preventive treatment.

While BOTOX® is approved and administered for chronic migraine, it is also used for other medical conditions. At Chinook Medical Centre, injections for migraine target specific muscles known to contribute to headache pain.

Some patients notice initial improvement within 4 to 6 weeks of the first treatment. Full benefits are typically achieved after 2 to 3 treatment cycles (approximately 24 to 36 weeks). Consistent treatment is important to maintain results.

Maintaining regular treatments every 12 weeks is crucial for sustaining migraine prevention. Chinook Medical Centre helps patients stay on track by scheduling follow-up visits at the time of treatment.

The most common side effect is neck pain. Other less common effects include temporary muscle weakness or mild discomfort at injection sites. It is important to discuss your medical history and any concerns with your Chinook Medical Centre provider before treatment.

Chronic migraine involves 15 or more headache days per month, each lasting 4 or more hours, with migraine symptoms on at least 8 of those days. Episodic migraine occurs less frequently. Both can significantly impact quality of life, and many patients with episodic migraine may also require preventive therapy depending on severity and disability.

Costs vary depending on insurance coverage and individual plans. Our team can help you understand your benefits and any potential out-of-pocket expenses before treatment begins.
