Flunarizine
About Flunarizine
Flunarizine is a prescription medicine used to prevent migraine headaches and manage vestibular disorders like vertigo. It serves as a preventive treatment, meaning it works to reduce the frequency and severity of attacks before they begin rather than treating a sudden, active episode.
Flunarizine is approved for use in several countries, including India, for migraine prevention and related conditions. However, its regulatory approval status differs between countries, and the US FDA does not approve it. Your doctor may prescribe it based on your individual health needs and available clinical guidance.
To achieve the best results, you must take this medicine consistently every day, preferably at bedtime. It can be taken with or without food, but keeping a regular schedule is crucial for its effectiveness. Incorporating a consistent sleep routine and staying well-hydrated can also support your treatment progress.
Common side effects of this medication include drowsiness, increased appetite, and gradual weight gain. However, you should consult your doctor immediately if you experience severe mood changes, feelings of depression, or unusual muscle movements like trembling or stiffness.
Before taking this medicine, talk to your doctor if you have a history of liver damage, depression, or movement disorders. Do not take this if you currently have active depression or Parkinson's disease, as this medication can worsen these specific conditions.
This medicine may interact with alcohol and sleep medications, causing severe drowsiness because they all slow down brain activity. If you are pregnant, breastfeeding, or are an older adult, consult your healthcare provider to discuss whether this treatment is safe for you.
