3 What Naratriptan tablets are and what they are used for
This medicinal product contains naratriptan which belongs to a group of medicines called triptans (also known as 5 HT, receptor agonists).
Naratriptan tablets are used to treat migraine headache with or without aura (a warning sensation that usually involves eyesight distortions, such as seeing light-flashes, zigzag lines, stars, or waves).
Migraine symptoms may be caused by the temporary widening of blood vessels in the head. Naratriptan is believed to reduce the widening of these blood vessels. This in turn helps to relieve the headache and other symptoms of a migraine attack, such as feeling or being sick (nausea or vomiting) and sensitivity to light and sound.
