Sumatriptan: what it is and what it is used for
This medication is often recommended to treat migraine attacks that cause possible throbbing headaches, as well as nausea and other symptoms.
Sumatriptan is a medication that is part of the group of drugs known as antagonists and is prescribed to try to relieve symptoms caused by migraine, such as throbbing discomfort that may be accompanied by nausea or increased sensitivity to sound or light. Sumatriptan is a selective serotonin receptor antagonist, specifically the 5HT1 receptor, which is involved in cranial vascular contraction. Migraine is the product of the expansion of blood vessels in the head, so the effect of sumatriptan is to contract them to relieve headaches and block the secretion of a series of natural substances that are what cause this pain and the rest of the symptoms that accompany a migraine.Sumatriptan is a medication that is part of the group of drugs known as antagonists.
How Sumatriptan is Taken
When starting treatment with sumatriptan or any other drug, you should carefully follow the instructions of the doctor or specialist who prescribed it. The consumption instructions are:
- Take it promptly at the time migraine symptoms begin to manifest. However, it should never be taken before an attack, since sumatriptan has no preventive effect.
- The recommended dose for an adult is 50 mg to 100 mg, but never doubling the intake for the same attack.
- It may happen that sumatriptan works by making migraine symptoms go away, but they return after a while. Then the indicated dose of the drug can be consumed again as long as at least 2 hours have passed since the intake of the first tablet. The maximum number of tablets that can be consumed within 24 hours must be indicated by the doctor.
- The administration of the drug is oral and in the form of oval and biconvex tablets. These should be taken whole, without chewing and with a little water. For people with swallowing difficulties, the tablets can be dissolved in a little water.
- A missed dose should not be made up.
- The recommended treatment usually lasts 10 days. This should not be interrupted if it is not by order of the doctor and it should not be extended longer than indicated. This could make the headaches worse or occur more frequently.

Additional information to consider
Before starting the consumption of sumatriptan, the doctor should be informed if they are taking other types of anti-migraine medication, since these could affect the properties of the drug. Other treatments for depression or manic/depressive illnesses such as bipolar disorder should also be considered.
- In the case of women who are or who are trying to become pregnant, talk to their doctor before starting treatment with sumatriptan. To date there is little information on the way in which the drug affects pregnancies and, although there is no evidence that it causes an increased risk of malformation, it is best to avoid its consumption. In the case of women who are breastfeeding, it is recommended that there be a space of 12 hours between the consumption of the medicine and the feeding of the baby.
- Currently, the efficacy of sumatriptan in children between 10 and 17 years of age has not been proven, so it is recommended that its use be avoided. The same goes for people over the age of 64.
- In patients with hepatic insufficiency or renal insufficiency, moderate and controlled use of the drug should be made.
