Sumatriptan
Sumatriptan Medical Valley contains 50 mg of sumatriptan in the form of sumatriptan succinate - an anti-migraine substance. Migraine symptoms may depend on the temporary expansion of blood vessels in the cervical artery circulation. Sumatriptan belongs to a group of drugs that are 5HT receptor antagonists, which narrow these blood vessels.
Sumatriptan can only be used in patients with a well-established diagnosis of migraine. Due to the lack of data, it is not recommended for patients with hemiplegic, basilar, or ophthalmoplegic migraine.
In patients with a headache of a migrainous type, in whom migraine has not been previously diagnosed, another cause of the complaint should be considered. A similar note applies to patients with previously diagnosed migraine but with an atypical picture of the current headache attack. It should be remembered that patients with migraine may belong to a group at risk of cerebrovascular damage, such as transient ischemic attack or stroke.
After administration of sumatriptan, transient chest pain and a feeling of pressure in the chest and throat may occur, sometimes of significant intensity. If the nature of these symptoms may indicate coronary heart disease, it is recommended to perform appropriate tests.
Sumatriptan should not be used in people at risk of cardiovascular disease, as well as in people who smoke or use nicotine replacement therapy, before performing appropriate tests to rule out these diseases. This group will include, among others, women after menopause, men over 40 years of age. However, it should be taken into account that not all tests performed allow for a proper diagnosis of existing heart disease, and that in very rare cases, severe cardiac symptoms can occur without underlying cardiovascular disease.
Sumatriptan may cause a temporary increase in blood pressure and an increase in peripheral vascular resistance. For this reason, in patients with controlled hypertension, the medicine should be used with caution.
The medicine should also be administered with caution to patients who may have changes in absorption, metabolism, or excretion, e.g., in patients with impaired liver or kidney function.
Sumatriptan should be used with caution in patients who have had seizure attacks.
In patients allergic to sulfonamides, after administration of sumatriptan, symptoms of allergy of varying severity may occur, from minor skin changes to anaphylactic shock.
Information on this is limited, so sumatriptan in patients with known hypersensitivity to sulfonamides should be used with caution.
The use of sumatriptan and preparations containing St. John's Wort (Hypericum perforatum) may increase the frequency of adverse reactions to sumatriptan.
Do not take more than the recommended dose of sumatriptan.
Long-term use of any painkillers can lead to an intensification of headache. If the patient experiences or suspects such a cause of headache, they should stop taking the medicine and consult a doctor. In patients who experience frequent or daily headaches despite (or due to) regular use of headache medications, consideration should be given to the diagnosis of medication-overuse headache.
The efficacy and safety of sumatriptan in children have not been established.
Data on the use of sumatriptan in people over 65 years of age are limited. No significant differences in pharmacokinetics have been found between this group of patients and younger individuals. Until more detailed clinical data are collected, the use of sumatriptan in this group of patients is not recommended.
Tell your doctor about all medicines you are taking, or have recently taken, and about medicines you plan to take.
Studies have not shown interactions between sumatriptan and ethanol, as well as drugs such as propranolol (used to treat hypertension), flunarizine (used to treat cerebral circulation disorders), and pizotifen (used to treat migraine).
During the use of ergotamine (used to treat migraine), prolonged vasoconstriction has been reported. Since these effects may be additive, sumatriptan should not be administered earlier than 24 hours after taking any ergotamine-containing preparation. On the other hand, ergotamine-containing preparations can be administered 6 hours after sumatriptan administration.
Rarely, interactions may occur between sumatriptan and selective serotonin reuptake inhibitors (used in depression).
In pregnancy, during breastfeeding, or if you think you may be pregnant, or are planning to become pregnant, consult your doctor before taking this medicine.
Pregnancy
There are no adequate human data. The use of the medicine in pregnant women should be limited to cases where the expected benefit to the mother outweighs the potential risk to the fetus.
Breastfeeding
Sumatriptan passes into breast milk. For 12 hours after taking sumatriptan, you should not breastfeed.
During the use of sumatriptan, drowsiness may occur, which may have a negative impact on activities that require increased attention, precise coordination, and quick decision-making (e.g., driving, operating machinery, working at heights, etc.). Do not drive or operate machinery for 24 hours after taking the medicine.
The medicine contains aspartame, a source of phenylalanine. It may therefore be harmful to patients with phenylketonuria.
The medicine contains lactose. If you have been diagnosed with an intolerance to some sugars, you should consult your doctor before taking the medicine.
Adults:
The recommended oral dose of sumatriptan is 1 tablet of 50 mg. However, sometimes a dose of 100 mg is recommended. If there is no response to the first dose, taking a second dose during the same migraine attack is not justified. In case of recurrence of symptoms, you can take one more dose of Sumatriptan Medical Valley, and in rare cases, a maximum of two doses of the medicine within 24 hours, taking into account the fact that the minimum interval between doses is 2 hours. The maximum daily dose should not exceed 300 mg.
Sumatriptan should be taken as soon as possible after the onset of a migraine attack, but the medicine taken at any stage of the headache is equally effective. The tablets should be swallowed whole, with water.
To open, bend a single square of the blister with the tablet and then tear it off along the perforation line. To remove the tablet, carefully remove the protective aluminum foil. The foil should be torn off from the corner with a smooth surface. Tablets should not be pushed through the foil.
Consult a doctor or pharmacist immediately.
Do not take a double dose to make up for a missed dose.
