What Naratriptan Orifarm is and what it is used for

Naratriptan Orifarm contains naratriptan (hydrochloride) which belongs to a group of medicines called triptans (also called 5-HT 1 – receptor agonists ).


Naratriptan Orifarm is used to treat the headache phase during a migraine attack.

The migraine symptoms are probably caused by a temporary dilation of the blood vessels in the head. Naratriptan Orifarm is considered to reduce the dilation of these blood vessels. This helps the headache to disappear and relieves other migraine symptoms such as nausea, vomiting, and sensitivity to light and sound.

Naratriptan contained in Naratriptan Orifarm may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professionals if you have any further questions, and always follow their instructions.
