Cymbalta’s Potential Side Effects
Potential Side Effects All Crazy Meds Have
No matter which neurological and/or psychiatric drug you take, you’ll probably get one or more of these side effects. These will usually be gone, or at least will diminish to the point where you barely notice it most of the time, within a week or two.
- Drowsiness / fatigue - even when taking stimulants in some circumstances.
- Insomnia, instead of or alternating with the drowsiness.
- Assorted other minor GI complaints (constipation, diarrhea, etc.)
- Generally feeling spacey / out of it
- Which can all add up to the ever-helpful “flu-like symptoms” listed as an adverse event on the PI sheet of practically every medication on the planet used to treat almost any condition humans and other animals could have.1
- All crazy meds can, and probably will affect your dreams as well. There is no way of telling if that will be good or bad, let alone if this side effect is permanent or temporary.
- Any of the above side effects you see listed again below means they’re even more likely to happen and/or stick around longer and/or are worse than most other meds.
Typical Potential Side Effects
The usual for SNRIs - headache, nausea, dry mouth, sweating, urinary hesitancy (it is a med for urinary incontinence after all), sleepiness or insomnia, diarrhea or constipation (my money is on the latter), weight gain, loss of libido and a host of other sexual dysfunctions. Most everything but the constipation, urinary hesitancy and weight gain, if any, will go away in a couple of weeks. As with most SNRIs sexual dysfunction is a coin toss, and many women will get a sexual boost instead of a sexual dampening.
Uncommon Potential Side Effects
Controlled narrow glaucoma
(but you already have to be at risk for eye problems to start with), elevated liver serum
(your doctor should have you get an annual liver panel), blurry vision
, muscle cramps
, and weight loss
(yes, that can be a problem).
Freaky Rare Side Effects
. Excessive disturbing and disabling yawning
. I guess they considered it “excessive and disturbing” because Lexapro
Not all side effects have been listed here, just the most likely and most interesting. For all reported side effects, see Cymbalta’s PI Sheet.
What You Really Need to be Careful About
Do NOT drink alcohol when taking Cymbalta. Your liver could explode. Cymbalta is NOT like SSRIs where an occasional drink is OK, or SNRIs where you risk only turning into a raging alcoholic. Cymbalta + booze = a short-lived raging alcoholic.
C-Use with caution
Cymbalta’s Noted Drug-Drug, Drug-Food & Drug-Supplement Interactions
- Luvox ( fluvoxamine ). As both an SSRI and an extremely potent CYP1A2 inhibitor, taking Luvox and Cymbalta together could either save you or seriously mess you up. Or both.
- Smoking can reduce the bioavailability and speed up the clearance of Cymbalta. It’s not known if you need to increase your dosage if you smoke. But as nicotine can reduce Cymbalta’s bioavailability by up to one third, and its bioavailability is only 50% to begin with, I imagine smokers (or however you indulge your nicotine habit) probably need more Cymbalta than the nicotine-free.
- As an inhibitor of CYP2D6, Cymbalta interacts with about half the meds discussed on this site, tamoxifen , and a buttload of others in the world’s pharmacopeia.

It’s always a good idea to check for drug-drug interactions yourself. Just because most people in the crazy meds business know about really important interactions (e.g. MAOIs and a lot of stuff, warfarin and everything on the planet) doesn’t mean the person who prescribed your meds told you about them, or the pharmacist has all the meds you take at their fingertips like they’re supposed to. Or they have the time to do their jobs properly when not dealing with complete idiots or playing Angry Farmers on teh Faecesbooks.
