Baclofen

12159

Baclofen is a GABA-like drug that has been used for decades in the treatment of spasticity. It has muscle relaxant, anxiolytic, and sedative properties.

Outside of its medical use for spasticity, it has been researched as a possible treatment for alcohol dependence.

The drug is sometimes taken in non-medical settings because it can provide anxiety reduction, sedation, and some euphoria. It’s usually described as somewhat similar to phenibut in its effects.

    I’ve noticed it to be inferior to other muscle relaxers, like Soma. It is better than Flexeril though.

      Very much agreed with that first part. I was Rx’d it for sleep for years. It really did nothing, but, I didn’t notice how little it did ’til I switched to Soma (carisoprodol), which works great. Better than Flexeril? I’d say both are pretty useless. MAYBE they do something if you mix with opioids and benzos.

        Very careful mixing anything like that. I know when in pain, you’re desperate … Trust me ,I know..
        I’ve never had a muscle relaxer help my back the way soma has..

        I’d rather be dependent on soma, and have more pain relief.

        Baclofen increases HGH, allowing you to get muscle back for PT. It helps involuntary muscle movements too. Just much less analgesia.

          Oh, I know. I’m done with opioids/opiates, unless you count the Subutex I take now. I haven’t used oxy/hydro/heroin/etc. for 3 and a half years now and I don’t take Subutex before sleep (when I take my Soma and when I took baclofen) – even though it does have a very long half-life. I just don’t think baclofen or Flexeril do anything for analgesia, even with opioids and/or benzos, in my experience.
