Overview

Medicines may stop a cluster headache after it starts or prevent more headaches from occurring. If you don't get headaches often, you may only need to take medicines after the headaches begin. If you get headaches often, you may need to take medicines daily during a cluster period to prevent a future headache or reduce the number of headaches in a cycle.

The choice of medicine may depend on the time of day when your headaches tend to occur. Some people may need a combination of two or three medicines. Finding the right medicine can take some time. Keeping track of your symptoms can help your doctor determine the proper medicine. You can keep track by using a headache diary.

When a cluster headache occurs, it is important to treat it as early as possible with the medicine your doctor has recommended. The sooner you treat the headache, the less painful it may be.

If your headaches become more severe and medicines aren't working, let your doctor know. You may need to try a different medicine or a combination of medicines. You may also need to be referred to a hospital or headache clinic for more intensive treatment.

Experts do not recommend opioid medicines, like oxycodone or hydromorphone, to treat cluster headaches. They can have harmful side effects.

To stop a cluster headache

Treatments most often used to stop cluster headaches include:

High-flow oxygen inhalation therapy.

You breathe oxygen through a face mask to relieve headache pain. Oxygen therapy is one of the best treatments to stop a cluster headache. Oxygen therapy relieves headache pain within 15 minutes in more than 7 out of 10 people who use it. It works best when started right when a cluster headache starts.^{footnote 1} But you need to repeat the treatment when the next headache begins.

Triptans.

Triptans can be given as a shot, sprayed in the nose, or taken by mouth as a pill to reduce pressure and pain.

Octreotide.

Octreotide can be used as a shot to stop headache pain.

Lidocaine.

Lidocaine is taken by nose drops to stop severe headache pain.

Ergotamine preparations.

These can be given in a vein or sprayed in the nose to relieve pressure and reduce headache pain.

Over-the-counter pain medicines, such as aspirin, acetaminophen, and ibuprofen, usually don't relieve the severe pain of cluster headaches.

To prevent headaches during a cluster period

Suboccipital steroid injection.

You must take these medicines every day during a cycle of headaches, even on days when you don't get a headache.
