Deseril Information

Deseril Details (Brand and Generic)

Our Canadian pharmacy currently offers the brand name Deseril from the United Kingdom manufactured by Alliance Pharms. There is no generic available for this medication.


Deseril tablets are available in the strength of 1 mg only.


Deseril (Methysergide Maleate) is used to prevent attacks of migraine and other types of headaches such as 'cluster' headaches and 'vascular' headaches. These headaches are thought to be caused by temporary changes in the size of small blood vessels in the brain. These blood vessels swell, causing the pain and visual disturbances that often happen during an attack. Deseril prevents the attack by affecting the blood vessels in the brain. It is particularly useful if you suffer from one or more migraine attacks per week. Deseril is only used to prevent migraine attacks from happening. It is not used to treat an attack once it has started. There are some types of headaches which must not be treated with Deseril. Deseril contains the active ingredient methysergide. It belongs to a group of medicines known as the "ergot alkaloids." Deseril can also be used to control diarrhea in carcinoid syndrome (a rare condition caused by a tumour in your appendix). Take this medicine with food to prevent stomach upset. Do not take Deseril for more than six months at a time without a break of 3-4 weeks. Do not give Deseril to children.
