Cymbalta for Fibromyalgia Treatment
In rare cases, a life-threatening condition called serotonin syndrome has occurred in patients who have taken Cymbalta. Serotonin syndrome most often results when someone takes two or more medications that increase the body's serotonin levels at the same time. You need serotonin for your brain and nerve cells to function, but too much of it can be dangerous. Serotonin syndrome can lead to rapid changes in blood pressure, muscle rigidity, seizures, and even death.
This is why it is so important that your health care providers know what medications you are taking. Always tell them about all the medicines you take, including over-the-counter drugs and herbs and supplements.
Drugs that may interact with Cymbalta and cause serotonin syndrome include:
- Cough medicines that contain dextromethorphan
- Monoamine oxidase inhibitors (MAOIs)
- Nausea and heartburn medications such as metoclopramide (Reglan) and ondansetron (Zofran)
- Pain medications, including meperidine (Demerol, a painkiller) and tramadol (Ultram)
- St. John's wort
- Triptans, used to treat migraine headaches
Other drugs may also interact with Cymbalta, including:
- Blood thinners, including warfarin, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs). Taking Cymbalta with such medications may increase your chances for bleeding events.
Before You Take Cymbalta
Tell your doctor about any other medical conditions you may have. The drug should be prescribed with caution in those who have:
- A history of seizures or mania
- Conditions that slow gastric emptying (sometimes occurs in those with diabetes)
- Diabetes (Cymbalta may effect blood sugar levels)
- High blood pressure or heart disease
- Liver disease
- Kidney disease
Who Should Not Take Cymbalta?
You should not take Cymbalta if you:
- Are taking a medication called thioridazine
- Are taking a medicine called MAOI or have used one in the last 14 days
- Have uncontrolled narrow-angle glaucoma
In animal studies Cymbalta has demonstrated adverse effects on a developing fetus. No adequate or well-controlled studies of the drug have been performed in pregnant or breastfeeding women. Women who are breastfeeding, pregnant, or planning to become pregnant should talk to their doctor about whether or not Cymbalta is right for them. You should only take Cymbalta if the benefits outweigh the risks.
