10 Rescue Migraine Medications

Migraine Medications

Migraine medications have come a long way in the past twenty years.

These injection medications were never mentioned to me other than in the emergency room.

But the word - injection - instils a sense of fear in me. I hate needles, but I hate migraine pain even more!

When migraineurs fail to respond to triptans or ergotamines, these ten migraine medications are used to find relief from acute episodes, as alternatives to the emergency department. They are all subcutaneously administered (under the skin). This means you may require some specialist training, and some courage.

If you get regular severe migraine attacks and are not able to make it to the emergency room in time, these migraine medications should be considered as part of your pain management plan. Feel free to print out this page and take it to your doctor to discuss your options.

Some of these drugs have too many side effects to list individually, so I have provided the more common ones.

I suggest that you do your homework with your doctor beforehand.

Plan ahead for your 'worst case’ scenario.

According to my research and drugs.com, the most common severe allergic reactions for these 10 migraine medications generally seem to include:

• itchy skin rash or hives
• breathing difficulties
• tight chest or chest pain
• "swelling of the mouth, face, lips, or tongue; unusual hoarseness; wheezing”
• reduced mental capacity with depression and confusion
• decreased coordination and motor function
• muscle weakness
• fainting
• irregular heartbeat
• muscle spasms and numbness in limbs
• agitation and restlessness
• seizures
• constipation
• a noticeable “shuffling walk”
• fatigue
• persistent nausea
• persistent vomiting
• cold or flu like symptoms
• similar “symptoms to liver problems”
• involuntary muscle twitching or twisting
• loss of balance
• unusual bruising or bleeding
• unusual eye movements or inability to move eyes
• unusual or excessive sweating
• unusual tiredness or weakness
• unusually pale skin and
• vision changes (ie. blurred vision).

According to my research, these seem to be the more general yet serious side effects listed for all ten rescue medications.

This list kind of makes me never want to take migraine medications ever again. If you are one of those people who do not respond well to the acute treatment strategies, and struggle your way through drugs for migraines, then I hope my migraine pain medication failed list will be of some motivation to help you persevere.

I feel we must stay focused and persevere to find the right migraine medications that work for us with the least amount of side effects. Or side effects that we can deal with from the medications that are less debilitating than the migraines alone.

Occipital Nerve Block

If you end up in hospital presenting with status migrainous, they may consider doing an occipital nerve block, in some countries, where “bupivacaine 0.5 percent 4 ml and triamcinolone 40mg (1ml)” is injected into your ipsilateral occipital notch. This means the top of the neck, behind your head. This injection should provide numbness for four to six hours, after which the pain should also subside.

It might be a good idea to discuss a worst-case scenario with your doctor, so you know in advance what possible rescue migraine medications might be best to use first. I keep a note in my wallet, just in case I ever need an injection and cannot speak.

There are so many migraine medications to choose from. Your doctor and pharmacist are the best starting point for getting all the necessary details. Gather all the information you can so you can make an informed decision when you need to act quickly.

Have a look at our migraine headache links page for some reputable websites. And come back and visit us as often as you'd like and read the new articles in this section on migraine medications.
