i take klonopin and it usually takes about 45-60 minutes to fully kick in. i have found that splashing cold water on my face, or soaking my feet in ice cold water or even taking a cold shower helps get my nerves under control while waiting for the meds to kick in. hope this helps!

I have been taking Klonopin for almost 5 years now for my panic disorder. It takes about 45 mins- 1 hour for me to feel the effects of the medicine. If you are in a panic-you can always let the medicine dissolve under your tongue, and it will enter your bloodstream quicker. However, I have found it is most effective when swallowed and waiting the 45-60 mins.

I take Klonopin 0.5mg p.o. prn for occasional anxiety, occasional sleeplessness, and for occasional, agitated lip pressing. I know it works for these three things. I was wondering how long it takes for an oral dose to reach the blood stream? It seems to work for me within about 35 minutes of swallowing, with water.

Klonopin has the second longest half life of all benzos only next to valium. So it takes a little longer to feel the initial effects of klonopin than say compared to xanax which has the shortest half life.
Most people won't feel the effects of klonopin in less than thirty minutes. It will probably take just a little longer than that.

Whoa there. Dalmane (Flurazepam), for example has a half-life of 40-250 hours. There's also Clorazepate, Nordazepam & a lot of other very long-lasting benzos I won't bother naming. My understanding has always been that Clonazepam is in the middle range when it comes to benzos half-lives.

Correct klonopin is middle half life. Most doctors like prescribing Klonopin or Valium over as an ax due to risk of seizures. Klonopin and Valium have anti-seizure properties, xanax does not. I have been on all three and Klonopin is terrible in my opinion Xanax is number one. Valium if you can't handle the amount of Xanax everyday prescribed without feeling withdrawal. If you're taking Xanax and having any withdrawal symptoms like it's not enough or quite lasting long enough then you need to switch to Valium which has a very long half-life. Each person is different I get 6mg Xanax a day so that's plenty for me but anything short of that I would have to be put on valium. I have been on that dosage since 1997 PTSD along with several other psychotic issues and Xanax is the only one that stops at dead in its tracks in 15 minutes on an empty stomach 30 minutes on a full stomach
