Cambia is licensed to relieve the symptoms of a migraine headache once it has started. The medicine is not, however, effective at preventing migraines from occurring. Cambia is a type of NSAID and works by blocking a specific enzyme in the body and reducing inflammation. "Off-label" uses of Cambia include the treatment of cluster headaches.
What Is Cambia Used For?Cambia™ (diclofenac potassium) is a prescription migraine medication. It belongs to a group of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). It comes in the form of a rapid-acting powder that is mixed with water.
Migraine headaches are different from other headaches in several aspects. Some of the most common migraine symptoms include:
- Headache pain on one side of the head
- Throbbing headache pain
- Sensitivity to light or sound
- Upset stomach (nausea) and vomiting
- Unusual vision changes.
Some people may have an aura before their migraines occur. An aura can be any unusual sign that a migraine is about to happen, including vision changes, numbness, tingling, or speech changes. The most common type of aura is visual (seeing spots, tunnel vision, or other vision changes). Some people have migraine triggers, which are certain foods, drinks, or situations that seem to lead to a migraine (see Migraine Diet for more information).
Cambia is approved for treating migraines with or without aura. It is not approved for migraine prevention.
How Does Cambia Work?Cambia belongs to a group of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). Like other NSAIDs, it works by blocking a specific enzyme known as cyclooxygenase (COX) and by blocking the production of various inflammatory substances in the body.
