Baclofen Muscle Spasticity Causes and Reviews


Neuromuscular disorders affect the nerves that control your voluntary muscles. Voluntary muscles are the ones you can control, like in your arms and legs. Your nerve cells, also called neurons, send the messages that control these muscles. When the neurons become unhealthy or die, communication between your nervous system and muscles breaks down. As a result, your muscles weaken and waste away. The weakness can lead to twitching, cramps, aches and pains, and joint and movement problems. Sometimes it also affects heart function and your ability to breathe.

Examples of neuromuscular disorders include

  • Amyotrophic lateral sclerosis
  • Multiple sclerosis
  • Myasthenia gravis
  • Spinal muscular atrophy

Many neuromuscular diseases are genetic, which means they run in families or there is a mutation in your genes. Sometimes, an immune system disorder can cause them. Most of them have no cure. The goal of treatment is to improve symptoms, increase mobility and lengthen life.

I just want anyone to answer my damn question is this site bogus cause i think its a fairly fucking easy question.i thought this is what is supposed to be done here

I too had a nasty bite from Baclofen.I had a craving for alcohol and was on 10 mg TID.I took 90mg at once. within one hour I feel like i was on shrooms! Very vivid CEVs(closed eyed visuals) and some ope eyed visuals(OEVs).Actually I enjoyed this.But there was moments of short anxiety.It was over in 6 hours maybe 8.I feel Baclofen has abuse potentials is some people and should be scheduled.It has a wide range of side effect and can be addictive. Kids use it for tripping or sedation.Baclofen is related to GHB and Phenethylamies(eg.Mecaline,2c-type drugs).Very dangerous in excess esp when starting it and for some withwardwal effects too. Be careful with it.Not suitable for alchoholics with history of Hallucinogen ause-like me. Im off this med now.

Can a DR, pharmacist(who knows what they're talking about) or patient, please tell me what the best most effective generic brand of Baclofen is. I've been on it for a yr+ via Walgreens CVS I've ONLY had access to Northstar, Teva I think 1x the Upsher-Smith brand. I've usually been getting 20mgx90 this mth I got 10mgx180 got Teva, I know that Watson, Qualitest, Mylan, Caraco, Lannett, Matrix make generic Baclofen too. I have to think 1 of them. probably Watson or Lannett, makes a superior product. I know not all generics are equal nor as effective. For ex...I'm also on Valium- Mylan makes the WORST diazepam ever, while Teva is ok Watson is by far the best. Thank you! I just want my Baclofen to be the most effective.
