What Is Lorcet Used For?

Lorcet is a semi-synthetic opioid pain killer which is derived from opium. The main ingredient in Lorcet is hydrocodone bitartrate.  Hydrocodone is combined with acetaminophen and is distributed only with prescription. Lorcet is prescribed for the relief of moderate to moderately severe pain and can also suppress or relieve coughing.

How Do You Take Lorcet?

Lorcet is taken orally as a tablet. But Lorcet can also be abused outside of medical use by crushing, chewing, snorting, or injecting the dissolved product. These modes of administration pose risk of drug addiction, overdose or death.

Peak Levels And Half Life Of Lorcet

After oral administration of standard 10/650 tablet of Lorcet, levels of hydrocodone and acetaminophen peak and then start to leave the body. Peak levels of Lorcet are most often associated with short term drug side effects which can give you and your doctor more information about whether or not Lorcet is the right medication for you. The half life for the ingredients in Lorcet give you an estimated time at which half of hydrocodone and acetaminophen have left your body. Following are the peak level and half life times for both hydrocodone and acetaminophen.

Hydrocodone – Average peak concentrations of hydrocodone occur in the body at 1 – 1.5 hours after taking Lorcet. The half-life of hydrocodone has been determined to be around 3.5 – 4 hours.

Acetaminophen – Acetaminophen is rapidly absorbed from the gastrointestinal tract and is distributed throughout most body tissues quickly. The plasma half-life of acetaminophen is 1-3 hours, but may be increased by liver damage.

Lorcet Drug Testing

Lorcet (actually the hydrocodone in Lorcet) can be detected on a DOT standard 5-panel drug test. In general, drugs are eliminated from the system at different rates and thus detectable for different periods of time. Sometimes the “detection window” of Lorcet even longer than the drug’s effect. In fact, as an opioid, hydrocodone can be detected for a certain amount of time after ingestion during which evidence can be detected by a drug test.

It’s also helpful to know that the detection window for Lorcet is the same as the hydrocodone drug test detection period.  Drug tests that laboratories order to test for the presence of Lorcet include an opiates immunoassay (urine test) with GC/MS or LC/MS/MS for opiates to confirm. So if you’re wondering how long Lorcet can stay and be detected in the body … the bottom link is that the main ingredient in Lorcet (hydrocodone) can be detected in urine for 2-4 days after you take Lorcet.

Lorcet And Addiction

Lorcet can be habit forming. Even if you take Lorcet as prescribed, you can become physically dependent on Lorcet, experiencing tolerance and withdrawal. But chemical dependence is different than addiction. Addiction has an element of psychological craving, or mental need, in addition to physical dependence. Is hydrocodone addictive? How much?   And who is at highest risk of Lorcet addiction?

recovery today.

If you like the euphoric effect of Lorcet and take it for non-medical reasons, your risk of Lorcet addiction is higher than if you were taking it as prescribed. Additionally, if you take Lorcet by crushing, chewing, snorting, or injecting the dissolved product, your risk for addiction increases even further.

Problems With Lorcet?

If you think that you’re taking too much Lorcet, or want to stop taking Lorcet…seek medical help. Abruptly stopping opioid medications like Lorcet will result in uncomfortable withdrawal symptoms and possible complications. Medical supervision is always suggested when you stop taking Lorcet. But sometimes detox is the easy part.

You can detox from the drug and get it out of your system. Then, you will need to learn how to live without it. If you need help getting started, please leave us a message here.

  1. today is november 11, I ran out of Oxy so I’ve taken 11 over the last 3 day’s. I have an appointment with my pain management Dr on November 18th which happens to be my B-Day plus I get injections in my neck and spine and I have scoliosis. I’m afraid the hydrocodone will show up and I can’t afford to lose them as I’m constantly in pain. Actually 3/4 of my new bottle were stolen but I don’t know who did it but too many ppl lie to their Dr’s just to get more but this most definitely isn’t my case. So, sorry for dragging it out but do you think I’ll pass my urine test? So, is 6-7 day’s going to be enough to get that many out of my system? I’d most appropriate any positive input please!? Thanks in advance

  2. Hello Kyle. After taking such doses and for such long time, as you already know, withdrawals are inevitable. To make the process of withdrawing and detoxing less painful you can talk to your doctor or general physician. They can help you with creating a tapering schedule, to gradually lower the doses and avoid withdrawals at their fullest severity. They can also prescribe some other medications to ease the symptoms. After all, it’s best and safest to do it under medical professionals’ supervision.

  3. I take in excess of 10 lorcets 225 or sad today and have been doing so far 10 years or more the withdrawals scare me but the mental part is 10 times worse please help

  4. me stop taking loracet. I have been taking in excess of 10 a day for 10 years or more. At time even up to 25 a day and I’m so tired of it and I’m scared of what I’m doing to my body. The withdrawals I hate but the mental part is 1000 times harder. Plz help

  5. Hello Neil. Consult with a physician. There are medications available to you during detox, but you’ll need a prescription for them. Additionally, an MD can help you by setting up a tapering calendar,… much less severe than going off Lorcet cold turkey.

  6. I want off loracets what can I take to get off of them for good. I tried cold turkey and got really sick.
