Placidyl Overview

Ethchlorvynol/θklrvanl/ is a sedative and hypnotic medication developed by Pfizer in the 1950s.[3] In the United States it was sold by Abbott Laboratories under the tradename Placidyl.[1] Placidyl was available in 200mg., 500mg., and 750mg. strength capsules. While the 500mg. and 750mg. strength capsules were for use in reducing sleep latency, the 200mg. strength capsules were intended to be used to re-induce sleep in case of early awakening. Abbott discontinued production in 1999,[1] af...

65 yr old life long traveling salesman living in motels town after town in stranger and strange places and always have had insomnia. Started in early 80s taking placidyl if spelled correctly then switched in 2000 to halcion. Now over the counter and I get very little sleep. ## Hello, Vic! How are you? Are you a frequent flyer, or often crossing time zones? It is well know that doing so can cause insomnia in some people. Many people have good luck using Melatonin to help reset their internal clock and, as reported by the FDA, it is basically side effect free, though some people may experience a little nausea. It is, however, always best to check with your physician, before taking anything. What are you currently trying to treat it?

Green liquid filled gel pillpills ## Hello, Sandie! How are you? Placidyl has been discontinued, but yes, they were green gel filled capsules that had the name and 750 on them in white lettering. The FDA classifies it as a sedative hypnotic that was most commonly used for reducing sleep latency. It often caused problematic side effects, such as skin rashes, hallucinations and amnesia, plus a sudden withdrawal created the risk of seizures, so it's been replaced by newer and safer medications. Are there any other questions or concerns? ## My doctor prescribed placidyl in the 50's for insomnia. Worked well, never any side-effects. I was sorry when they took it off the market. Several years ago, my current doctor prescribed Ambien - I took it once and sleep-walked. The new sleep aid...

I have had almost every kind of sedative-hypnotics prescribed to me (Including Doriden, Noludar, Seconal, and Placidyl). Placidyl has a funny, fruit-like odor and taste to it.It was an effective hypnotic for sleep and I didn't wake up with a headache or a "hangover". Placidyl took effect in about 15 minutes and lasted all night long. It not only acted as a hypnotic, but as a sedative too. Eli Lilly&Co. ceased distribution of this drug in the late 1990's. ## If it was discontinued, there isn't much you can do about it. Are you currently trying anything else? Have you tried any of the Benzodiazepine class of medications, such as Xanax? ## Placidyl was one of the most effective sleep aids ever made. Abbott was the company that discontinued it in 1999. If you took on...

it is almost like a supository shaped pill Dark green with a black liquid inside. no odor to liquid. ## It sounds like a placidyl - scientific name is - ethchlorvynol. Uses - This medication is used as a sleeping aid for short-term treatment of insomnia. It is usually not prescribed for longer than a one week period. - This medication is best taken 15 to 30 minutes before bedtime. Take this medication with food to prevent dizziness. it sounds like a 750mg Placidyl, But I thought the FDA pulled them from the pharmacy shelves back in 1999 / 2000. At any rate I would go on to a pill identifier website that has pictures to make sure.. Placidyl's are a very strong sedative.. Once that capsule exterior disolves ( approximately 15-30 minutes) it has a hell of kick/rush when it kicks in and...
