Sumatriptan
Imigran FDT contains the active substance sumatriptan. Sumatriptan acts on specific receptors in blood vessels in the area supplied by the carotid artery, selectively constricting these vessels. Sumatriptan also inhibits the activity of the trigeminal nerve. Both mechanisms are responsible for the anti-migraine effect of the medicine.
Imigran FDT is used to treat migraine attacks with or without aura. Imigran FDT should only be used after the onset of migraine attack symptoms. It should not be used as a preventive measure.
Before starting treatment with Imigran FDT, tell your doctor if you have:
headache, but migraine has not been previously diagnosed in you,
headache that is different from the one that usually occurs during a migraine attack,
shortness of breath, pain, or feeling of pressure in the chest (which may radiate to the jaw or shoulders) of unknown cause,
heart disease risk factors (men over 40 years old, postmenopausal women, overweight people, diabetics, high cholesterol levels, smokers, family history of heart disease),
liver or kidney function disorders,
history of seizures or predisposition to seizures,
allergy to sulfonamide medicines, as there is a possibility of allergic reactions of varying severity after sumatriptan administration: from skin changes to anaphylactic shock,
mild controlled hypertension, as a transient increase in blood pressure and peripheral vascular resistance may occur.
During concomitant use of sumatriptan and selective serotonin reuptake inhibitors (medicines used to treat depression), serotonin syndrome has been rarely reported, including changes in mental state, autonomic disorders (disorders related to the malfunction of the part of the nervous system responsible for involuntary functions, e.g., gastrointestinal disorders, circulatory disorders, excessive sweating, excessive salivation) and neuromuscular disorders. Serotonin syndrome has also been reported during concomitant use of triptan and serotonin-norepinephrine reuptake inhibitors (medicines used to treat depression). If concomitant treatment with sumatriptan and a selective serotonin reuptake inhibitor or serotonin-norepinephrine reuptake inhibitor is clinically justified, the patient should be under medical supervision.
During concomitant use of sumatriptan and St. John's Wort (Hypericum perforatum) products, adverse reactions may occur more frequently.
Overuse of medicines for the acute treatment of migraine attacks, including triptans and painkillers, may be associated with worsening of headaches in sensitive patients (medication overuse headache, MOH). In each patient who experiences an increase in frequency or severity of migraine during treatment, the doctor should consider the diagnosis of medication overuse headache. In these patients, it may be necessary to discontinue treatment.
Imigran FDT is not recommended for use in children and adolescents.
Imigran FDT is not recommended for use in elderly patients (over 65 years old).
Tell your doctor about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
After taking Imigran FDT, do not take any medicines containing ergotamine or its derivatives for 6 hours, and triptans or other 5-HT receptor agonists for 24 hours. On the other hand, after taking any ergotamine-containing medicine, another triptan, or other 5-HT receptor agonist, do not take Imigran FDT for at least 24 hours.
Do not take Imigran FDT at the same time as MAOIs and for 2 weeks after stopping treatment with these medicines.
During concomitant use of sumatriptan and St. John's Wort (Hypericum perforatum) products, adverse reactions may occur more frequently.
During concomitant use of sumatriptan and selective serotonin reuptake inhibitors, serotonin syndrome has been rarely reported (including changes in mental state, autonomic disorders, and neuromuscular disorders). Serotonin syndrome has also been reported during concomitant use of triptans and serotonin-norepinephrine reuptake inhibitors (see Warnings and precautions).
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine. Sumatriptan passes into breast milk. Therefore, during the 12 hours after taking Imigran FDT, it is recommended to avoid breastfeeding.
Due to a migraine attack or after taking Imigran FDT, drowsiness may occur. In such cases, do not drive or operate machinery.
Imigran FDT, 50 mg, coated tablets / oral suspension tablets, and Imigran FDT, 100 mg, coated tablets / oral suspension tablets contain less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".

Imigran FDT should only be used after the onset of migraine attack symptoms, it should not be used as a preventive measure.
Do not exceed the recommended dose.
Swallow the tablets whole with water. If you have difficulty swallowing, the tablet can be dissolved in a small amount of water before administration. The medicine prepared in this way has a bitter taste.
The usual dose of Imigran FDT is 50 mg, taken as soon as possible after the first symptoms of migraine appear; however, the medicine is equally effective when taken at any stage of the pain. Some patients may require a dose of 100 mg - follow your doctor's instructions.
If the symptoms of the migraine attack do not disappear after taking the first dose, taking a second dose during the same attack is not recommended. In such cases, you can use paracetamol, acetylsalicylic acid, or another non-steroidal anti-inflammatory medicine.
In the event of a recurrence of symptoms, you can take further doses of Imigran FDT, but not earlier than 2 hours after the first dose.
Do not take more than 300 mg in 24 hours.
