Common use

Flunarizine is a selective calcium channel blocker that belongs to the diphenylpiperazine class of medications. It is primarily prescribed for migraine prevention, helping to reduce both the frequency and severity of migraine attacks in patients who suffer from recurrent headaches. As a headache prevention medication, flunarizine works by blocking the entry of calcium ions into smooth muscle cells and neurons, which helps stabilize blood vessel tone and reduce neuronal hyperexcitability — two key factors in migraine development.

Beyond its well-established role in migraine prevention, flunarizine is also widely used as a vertigo treatment for patients with vestibular disorders. The medication helps alleviate symptoms of dizziness, balance disturbances, and motion sensitivity associated with various vestibular conditions. Additionally, flunarizine may be prescribed for patients with peripheral vascular disease and certain forms of epilepsy, demonstrating its versatile therapeutic profile.

When you buy Flunarizine online, you are choosing a prophylactic medication with decades of clinical evidence supporting its effectiveness in reducing migraine frequency. Flunarizine generic versions offer the same active ingredient and therapeutic benefits at a more affordable price. Whether you need to buy flunarizine for migraine prevention, vestibular disorder management, or vertigo treatment, this calcium channel blocker provides reliable, well-documented results.



Dosage and direction

Flunarizine is an oral medication that comes in 10 mg capsules. The standard dosing recommendation is to take one capsule once daily in the evening, preferably at the same time each day to maintain consistent blood levels and to minimize the possibility of missing a dose. Taking flunarizine at bedtime also helps manage drowsiness, which is a common initial side effect of this calcium channel blocker.

The usual dosage for adults undergoing migraine prevention is 10 mg (one capsule) per day. For elderly patients (aged 65 and above) and for younger children, the dosage should be reduced to 5 mg daily as directed by the prescribing physician. Treatment duration for headache prevention is typically assessed after 2-3 months, and maintenance therapy may be recommended for patients who respond well. Do not exceed the prescribed dose without medical supervision.



Precautions

Before you buy Flunarizine online or begin this prophylactic treatment, notify your doctor if you are pregnant, planning to become pregnant, or breastfeeding. The use of flunarizine during pregnancy may cause birth defects in unborn babies and could also cause problems in newborn infants. This calcium channel blocker should be administered with particular caution in patients aged 50 and above, as they may be more susceptible to extrapyramidal side effects.

Inform your doctor if you suffer from serious liver, kidney, or heart dysfunction, as dose adjustments may be necessary. Flunarizine treatment, even at recommended doses, can produce motor disturbances (extrapyramidal symptoms) in patients who previously showed no neurological deficits. For this reason, patients on flunarizine therapy should be followed closely and monitored at regular intervals so that any emerging extrapyramidal symptoms can be detected early and managed appropriately. Avoid driving or operating heavy machinery until you know how this medication affects you.



Contraindications

Flunarizine is contraindicated in patients with known hypersensitivity to the drug or any of its inactive ingredients. This medication should not be used by individuals with a current or past history of depression, as flunarizine may worsen depressive symptoms. Patients with pre-existing extrapyramidal disorders, including Parkinson's disease or drug-induced parkinsonism, must also avoid this calcium channel blocker. Your doctor will evaluate your complete medical history before prescribing flunarizine for migraine prevention or vestibular disorder treatment.



Possible side effect

At the beginning of flunarizine treatment for migraine prevention, you may experience drowsiness, weight gain, dry mouth, heartburn, nausea, or mild anxiety. These initial side effects typically diminish as your body adjusts to the medication over the first few weeks of therapy. Weight gain is among the most commonly reported long-term side effects and should be monitored throughout treatment.

More significant adverse reactions that require medical attention include skin rash, depression, muscle aches, tremor, difficulty moving, and abnormal or uncontrolled movements (signs of extrapyramidal symptoms). If you notice any of these symptoms during your vertigo treatment or headache prevention regimen, contact your doctor promptly. Early detection of movement-related side effects is important for preventing irreversible neurological complications.



Drug interaction

Flunarizine may interact with several categories of medications, and these interactions should be carefully considered before starting this calcium channel blocker. Inform your doctor about all medications you are taking, including sedatives, anti-anxiety medications, muscle relaxants, tranquilizers, anti-seizure medications, and any other central nervous system depressants. The concurrent use of flunarizine with these medications may enhance drowsiness and sedation. Alcohol should be avoided during treatment as it can potentiate the sedative effects of flunarizine.



Missed dose

If you missed a dose of flunarizine, take it as soon as you remember, provided it is not too close to your next scheduled dose. If it is almost time for your next dose, skip the missed dose and continue with your regular migraine prevention schedule. Never take a double dose to compensate for a missed one, as this increases the risk of side effects without additional prophylactic benefit.



Overdose

Signs of flunarizine overdose may include excessive sedation, asthenia (physical weakness), central nervous system effects such as confusion, severe drowsiness, and agitation, as well as cardiovascular effects including tachycardia (rapid heart rate). In case of suspected overdose, notify your doctor immediately and seek urgent medical assistance. Treatment is primarily supportive and symptomatic.



Storage

Store flunarizine at room temperature, below 25 C (77 F), in a dry place that is not accessible to children and pets. Protect from direct light and moisture. Do not use the medication beyond its expiration date.
