Imitrex (Sumatriptan) 25 mg, 50 mg, 100 mg precautions and dosage
Imitrex is indicated in case of cluster headaches and migraines, if the patient does not have history of cardiac diseases, and is not hypersensitive to the drug's components. It's important to consult a doctor before trying to self-medicate, because Sumatriptan has a strong effect on body, particularly the blood vessels, and its improper use can lead to risk of cardiac problems, such as myocardial infarction and many others. It is important to adjust the Imitrex dosage to individual needs and conditions of the patient, which can be done by professional medic only, after a thorough examination.
Typically, the medication should be applied immediately after the first manifestation of the migraine symptoms. It takes some time to take effect, especially if you're using the oral intake path. Intravenous solution takes approximately 10-15 minutes to take effect; nasal spray is nearly as effective and fast; tablets may take longer time to sooth the pain, because they have to be digested in order for Sumatriptan to get into blood. Higher doses of the medication do not necessarily mean better effect: there is a limitation for the absorption of the drug in brain, which is independent of the dosage. However overdosing Imitrex is dangerous for health, because its effect on cardiovascular system can be devastating.
Standard dose of the drug is 50 or 100 mg tablet once daily. Maximum daily dosage of Sumatriptan should not exceed 200 mg. Nasal spray dose is 5 or 10 mg once daily in one nostril. Maximum dose should not exceed 40 mg within 24 hours. If the first dose of the medication has not taken effect, you should not take the other dose earlier than 2 hours after the first intake.
Sumatriptan side effects
Typical side effects associated with Sumatriptan therapy are chest pain and abnormal sensations, such as warm or cold skin sensations or paresthesias. Over 2% of the patients report such side effects. Lesser number of patients complain about sleep disturbances, vertigo and abnormal fatigue.
Serious complications may occur in case the patient has overdosed the medication, or if the hypersensitivity (contraindications) were not determined timely. In this case, the patient is exposed to risk of coronary artery vasospasm, myocardial infarction, myocardial ischemia, or ventricular tachycardia. Any sign of such adverse effects of Sumatriptan require immediate medical investigation.
Sometimes, long-term intake of Sumatriptan (Imitrex) can result in a rare health condition known as sulfhemoglobinemia. It makes the blood turn dark-green, because of the abnormal amount of sulfur in hemoglobin molecules.
Cost of Imitrex (Sumatriptan) medication
While Imitrex is very popular and many patients need it to soothe their migraines and cluster headaches, not all the insurance companies include this drug into their medical insurance programs. In this case, price of Sumatriptan without insurance can be a serious reason to review the treatment, turning to generic medications. Such medications are legal and checked, because the patent on Imitrex has expired in 2009. They have identical compound, and mechanism of action, but much lower cost because the companies do not overprice generic medications.
Typically, 6 Sumatriptan tablets of 100 mg each can cost up to $25, if you order generic Imitrex (Sumatriptan) online with no prescription. Price of Sumatriptan at Walmart (Walgreens) can be several times higher than that.
