‹ SSRIs | Antidepressant Topic Index | SNRIs ›
Norepinephrine-Selective Reuptake Inhibitors (NSRIs) discussed on this site include:
We pretty much have a choice of two NSRIs, Strattera (atomoxetine HCl) in the US and Canada, and Edronax (reboxetine mesylate) most everywhere else. Viloxazine may still be available in the US, but I can’t find any information about its availability one way or the other. The only references to it on the FDA’s website and Drugs.com are on documents about other meds.
Norpramin (desipramine HCl) is a TCA, and like all TCAs is an antihistamine, anticholinergic, norepinephrine antagonistic and does some, but barely any, serotonin reuptake inhibition. Despiramine barely does much of anything in the way of serotonin reuptake inhibition and is about as close to an NSRI as you’re going to get if Strattera/reboxetine worked but the side effects where too much. Vivactil (protriptyline HCl) is also a good substitute, but obscure and expensive. At 50mg a day the generic costs over $300 a month when you have to pay full retail.
Strattera doesn’t even have FDA approval to treat depression, but it looks and acts so much like reboxetine that it may as well be an antidepressant.
NSRIs (i.e. Strattera and reboxetine, I may or may not - odds on may not - cover viloxazine) have a few things in common:
- Low side effect profile
- While the possible side effects a fewer, and generally suck less, than those associated with SSRIs, SNRIs, TCAs and MAOIs, you’re actually more likely to have the common side effects, and for those problems to stick around.
- No discontinuation syndrome like SSRIs and SNRIs
- But they’re more likely to poop-out (tachyphylaxis) than SSRIs, and you don’t have much choice in the way of other meds to try if that happens.
- At least the poop-out effect may not be totally random. Based upon anecdotal evidence only it seems like taking too much too soon, a common even with Strattera, frequently leads to Strattera’s failing. Sometimes it will work again, sometimes it won’t.
- They’re less likely to trigger mania in the bipolar than SSRIs
- But if you’re bipolar and aren’t stable, they’ll destabilize you further.
- And it might be difficult to tell if you’re manic in the first place when one side effect is a short-term euphoria.

The information on Crazy Meds pertains to and is intended for adults. While some information about children and adolescents is occasionally presented (e.g. US FDA approvals), pediatric-specific data such as dosages, side effects, off-label applications, etc. are rarely included in the articles on drugs or discussed on the forum. If you are looking for information regarding meds for children you’ll have to go somewhere else.
Know your sources!
Nobody on this site is a doctor, therapist, or a pharmacist. We don’t portray them either here or on TV. Only doctors can diagnose and treat an illness. Some doctors tend to get pissed off by patients who know too much about medications, so tread lightly when and where appropriate. Diagnosing yourself from a website is like defending yourself in court, you suddenly have a fool for a doctor. Don’t be a cyberchondriac, thinking you have every disease you see a website about, or that you’ll get every side effect from every medication*. Self-prescribing is as dangerous as buying meds from fraudulent online pharmacies that promise you medications without prescriptions.
All information on this site has been obtained through our personal experience and the experiences family, friends, what people have reported on various reputable sites all over teh intergoogles, the medications’ product information / summary of product characteristic (PI/SPC) sheets, and from sources that are referenced throughout the site. As such the information presented here is not intended as a substitute for real medical advice from your real doctor, just a compliment to it. You should never, ever, replace what a real doctor tells you with something from a website on the Internet. The farthest you should ever take it is getting a second opinion from another real doctor. Educate yourself - always read the PI/SPC sheet or patient information leaflet (PIL) that comes with your medications and never ever throw them away.
Crazy Meds is not responsible for the content of sites we provide links to. We like them, or they’re paid advertisements, or they’re something else we think you should read to help you make an informed decision about a particular med. Sometimes they’re more than one of those things. But what’s on those sites is their business, not ours.
Very little information about visitors to this site is collected or saved. From time to time I look at search terms used and which pages they bring up in an effort to make the information I present more relevant. And the country of origin, just because I’m geeky like that. That’s about it. Depending on how you feel about Schrodinger, our privacy policy should either assuage or exacerbate your paranoia.
All brand names of the drugs listed in this site are the trademarks of the companies named on the PI/SPC sheet associated with the medication, sometimes on the pages about the drugs, even though those companies may have been acquired by other companies who may or may not be listed in this site by the time you read this. Or the rights to the drug were sold to another company. And any or all of the companies involved may have changed their names.
Crazy Meds is optimized for the browser you’re not using on the platform you wish you had. Between you and me, it all looks a lot cleaner using Firefox.
