What is cluster headache?
Cluster headache is a very painful headache on one side of the head, near the eye. An attack lasts 15 minutes to 3 hours. Attacks can come many times a day for weeks or months. For most people, they then stop for a while. This visit is for people who already have this diagnosis from a clinician. It treats an attack once it starts.
Who is this visit for?
Adults 18 to 64. A clinician told you that you have cluster headache. Your attacks are like the ones your clinician diagnosed. In the last 12 months, you had a blood pressure reading below 140/90. A pharmacy machine or a home cuff counts. If you never used a triptan, you are 49 or younger. We do not order tests. We do not prescribe controlled medicines.
What is the shot plan?
The doctor reads your answers. If it fits, the doctor sends a prescription for sumatriptan 6 mg autoinjectors. An autoinjector is a pen that gives a shot. You get 8 shots for 30 days. Use 1 shot under the skin when an attack starts. You may use it at any time in an attack. If the pain comes back, or you only got some relief, you may use a second shot. Wait at least 1 hour after the first. Never use more than 2 shots in 24 hours. Do not use another triptan or an ergot medicine within 24 hours of a shot. Ask the pharmacist to show you how to use the pen. Read the leaflet in the box. For your first shot, have another adult near you if you can. This medicine can make you dizzy or sleepy. Do not drive until you know how it affects you.
Why can you not send oxygen, and who can?
Oxygen through a mask is a first-choice treatment for attacks. An expert review says it has no side effects. We cannot send it. It needs a home oxygen order and a supplier. Ask your own doctor or neurologist for one. If you already have oxygen, keep using it the way your doctor showed you.
Does this visit prevent attacks?
No. This visit does not prevent attacks. Medicines that prevent them, such as verapamil and lithium, need heart tracings or blood tests. We do not prescribe them. Your neurologist or own doctor manages prevention. Needing many shots in a month is a sign to ask about prevention.
What should I know about safety?
Tell us about every medicine you take. The shot can cause a serious problem called serotonin syndrome, mostly with some antidepressants. Tell us if you are breastfeeding. The label says that waiting 12 hours after a shot to breastfeed lowers your baby's exposure. Smoking and alcohol can set off attacks. Keep a headache diary. Write down each attack and each shot. Put used pens in a sharps container.
How do refills work?
There are no automatic refills. A short check-in comes before each refill. It asks about the warning signs on this page again. The first check-in is free.
When should I get help right away?
Do not wait for our reply if a warning sign on this page starts. Our reply can take up to 6 hours. If more than one warning sign fits, follow the first one. Call or text 988 any time if you have thoughts of ending your life or of hurting yourself. Do not drive yourself to the ER.
