If you have migraine, your doctor might suggest Cambia as a treatment option. It’s a prescription drug used in adults to treat migraine with and without aura.

It’s important to note that Cambia is only used to treat a migraine episode that’s already happening. It should not be used to prevent migraine headaches. And it’s unknown whether Cambia is safe to take for a cluster headache.

The active ingredient in Cambia is diclofenac potassium. (The active ingredient is what makes the drug work.) It belongs to a group of medications called nonsteroidal anti-inflammatory drugs (NSAIDs).

The powder is in a packet. You can take the powder by mouth.

This article describes the dosage of Cambia, as well as its strength and how to take it. To learn more about Cambia, see this in-depth article.

Note: This chart highlights the basics of Cambia’s dosage. Be sure to read on for more detail. And please keep in mind that this article covers Cambia’s standard dosage schedule, which is provided by the drug’s manufacturer. But always follow the dosing instructions given to you by your doctor.

You should not use this medication to treat a cluster headache since it’s not known if the drug may be safe or effective for this use.

You should not use it to prevent migraines. This is not a drug that you take once a day. It should only be used to treat a migraine that is happening.

You should try not to take Cambia 10 or more days per month. Doing so may cause medication overuse headaches, which may be more frequent or more severe than your original migraine headaches. If you develop medication overuse headaches, your doctor will likely pause your treatment with Cambia until your symptoms go away.

If you have questions about the dosage, talk to your doctor.

Is Cambia used long term?

It can be used as a long-term treatment. This medication should only be used for migraines that are already-occurring. If you and your doctor determine that Cambia is safe and effective for treating this condition, you will likely use it for a long time.

The powder should be mixed into the water to make a liquid solution. You should drink this as soon as you mix it. Do not mix other liquids with it. You should mix it with water.
