Dihydroergotamine nasal solution is used to treat the painful and debilitating symptoms that are caused by migraine headaches. It is also sometimes used to manage withdrawal from analgesics and to treat acute intractable headaches. However, dihydroergotamine cannot be used to treat any other form of bodily pain.
Dihydroergotamine is one of a group of drug called ergot alkaloids. The medication works by causing vasoconstriction of the blood vessels inside the skull. It also acts centrally on the adrenergic, serotonin, and dopamine receptors within the brain.
It should be noted that dihydroergotamine sometimes causes the blood vessels elsewhere in the body to constrict, potentially causing circulatory problems in vulnerable people.
In the US, dihydroergotamine is known under the brand name, Migranal. This drug is only available on prescription from your GP or treating specialist.
Some medications cause unwanted side effects, as well as the effects they are designed to produce.

You must not use dihydroergotamine to treat any headache other than a migraine. Ask your doctor for advice on this.
For dihydroergotamine to be as fully effective as possible, you must use it as soon as you feel a migraine developing. However, do not take the medication until the actual headache starts. If you experience familiar warning signals, such as an aura, wait until the actual headache pain begins before using dihydroergotamine nasal spray.
If possible, lay down in a darkened, quiet room after using the medication. This should help to dispel the migraine.
You should use dihydroergotamine as directed by your GP. However, if your headache returns following initial relief as a result of using the drug, you may use one further dose. That said, you should not ideally use more of the medication or use it more frequently than you have been told to.
Your treating physician may recommend another medicine to take in order to prevent headaches. You should follow your doctor's instructions, even if the headaches continue to happen. In some patients, headache medication can take a few weeks to become fully effective. Once the drugs begin to work, you should experience fewer headaches, and they should be less debilitating and easier to relieve. Ultimately, this should mean that you can reduce the dose of dihydroergotamine nasal spray and other analgesic drugs that you need to take. If there is no appreciable improvement following a few weeks of using headache prevention medication, you should speak to your GP.
You should note that the dose of dihydroergotamine nasal spray will vary between patients. Always follow the dosage instructions given to you by your GP or those on the product label.

Your recommended dose will depend on the potency of the preparation you are prescribed. The number of daily doses you use, the time you must leave between them, and the total duration of your course of dihydroergotamine will be dependent on your condition and how your body responds to the drug.
Some drugs should never be used at the same time as dihydroergotamine. However in some cases, where the patient's condition merits it, two or more medicines may be used with dihydroergotamine nasal spray, even though an interaction may occur.
