| The epidemic of opioid addiction sweeping the country has led to another form of drug abuse that few experts saw coming: Addicts who cannot lay hands on painkillers are instead turning to Imodium and other anti-diarrhea medications. | The epidemic of opioid addiction sweeping the country has led to another form of drug abuse that few experts saw coming: Addicts who cannot lay hands on painkillers are instead turning to Imodium and other anti-diarrhea medications. |
| The active ingredient, loperamide, offers a cheap high if it is consumed in extraordinary amounts. But in addition to being uncomfortably constipating, it can be toxic, even deadly, to the heart. | |
| A report published online in the Annals of Emergency Medicine recently described two deaths in New York after loperamide abuse. And overdoses have been linked to deaths or life-threatening irregular heartbeats in at least a dozen other cases in five states in the last 18 months. | A report published online in the Annals of Emergency Medicine recently described two deaths in New York after loperamide abuse.

| Most physicians just recently realized loperamide could be abused, and few look for it. There is little if any national data on the problem, but many toxicologists and emergency department doctors suspect that it is more widespread than scattered reports suggest. | Most physicians just recently realized loperamide could be abused, and few look for it.

| As efforts to limit prescription opioids intensify, a handful of experts are concerned that more addicts might turn to loperamide — much as an alcoholic might resort to mouthwash when the Jim Beam runs dry. | As efforts to limit prescription opioids intensify, a handful of experts are concerned that more addicts might turn to loperamide — much as an alcoholic might resort to mouthwash when the Jim Beam runs dry. |

| He added, “A subset of patients take it to get high, and other patients use it as a bridge” — meaning that if they cannot obtain heroin or morphine, they take loperamide to ease withdrawal symptoms like muscle pains, vomiting, diarrhea and nausea. | He added, “A subset of patients take it to get high, and other patients use it as a bridge” — meaning that if they cannot obtain heroin or morphine, they take loperamide to ease withdrawal symptoms like muscle pains, vomiting, diarrhea and nausea. |

| The recommended dose of loperamide is safe. The standard daily dose of Imodium A-D is no more than four caplets, or eight milligrams. But lobe abusers — as they sometimes call themselves — have reported ingesting 100 two-milligram tablets daily for weeks. | The recommended dose of loperamide is safe.

| In a case reported by Dr. Eggleston and his colleagues, a 24-year-old man experiencing opiate withdrawal took so much loperamide that he died. Toxicology analysis found more than 25 times the regular dose in his blood. | In a case reported by Dr. Eggleston and his colleagues, a 24-year-old man experiencing opiate withdrawal took so much loperamide that he died.

| In another case, a 39-year-old man collapsed at home and was pronounced dead at a hospital. His family said he had once managed his opioid addiction with prescription buprenorphine, but had taken to medicating with anti-diarrhea drugs. | In another case, a 39-year-old man collapsed at home and was pronounced dead at a hospital.

| Anti-diarrhea medications are cheap, legal and can be bought easily in large quantities without raising suspicion. Costco sells 400 loperamide caplets for just $7.59. | Anti-diarrhea medications are cheap, legal and can be bought easily in large quantities without raising suspicion.

| Yet loperamide used to be a prescription drug and a controlled substance, in the same class as cocaine or methadone. The F.D.A. approved it in 1976, and it became an over-the-counter drug in 1988. | Yet loperamide used to be a prescription drug and a controlled substance, in the same class as cocaine or methadone.

| Typically, loperamide acts on opioid receptors in the gastrointestinal tract and does not enter the central nervous system. At recommended doses, there is no high, and low potential for abuse. But large doses can produce a high, doctors say. | Typically, loperamide acts on opioid receptors in the gastrointestinal tract and does not enter the central nervous system.

| Some toxicologists argue that the sales of loperamide should be limited, much as the nonprescription drug pseudoephedrine was restricted a decade ago to help prevent the manufacturing of crystal meth. | Some toxicologists argue that the sales of loperamide should be limited, much as the nonprescription drug pseudoephedrine was restricted a decade ago to help prevent the manufacturing of crystal meth. |

While there, unknown to doctors, she was still taking 100 tablets of loperamide a day from a private stockpile. | After repeated blackouts, she sought medical attention at a hospital.

| “If you take enough, it rushes the gate, and some penetrates the blood-brain barrier,” Dr. O’Connell said. “Once it crosses the barrier, it can act on the central nervous system and you get euphoric effects.” | |
| Some users complain the high does not compare to that produced by opioids. “You can definitely get high from it, and even kill yourself with it,” a commenter wrote in 2013 on Bluelight, a website where people discuss drug use. | Some users complain the high does not compare to that produced by opioids. “You can definitely get high from it, and even kill yourself with it,” a commenter wrote in 2013 on Bluelight, a website where people discuss drug use. |

| Another commenter cataloged loperamide’s downsides — the need to continually take stool softeners, for one — but wrote that the medication took away the misery of opioid withdrawal: “Don’t wish to be dead … so that’s a plus.” | Another commenter cataloged loperamide’s downsides — the need to continually take stool softeners, for one — but wrote that the medication took away the misery of opioid withdrawal: “Don’t wish to be dead … so that’s a plus.” |

| Some loperamide abusers arrive at hospitals lethargic or not breathing, as if they had overdosed on heroin. Naloxone, an anti-opioid drug, may be given. | Some loperamide abusers arrive at hospitals lethargic or not breathing, as if they had overdosed on heroin.

| In one case at the hospital, opioid abuse was suspected after a 19-year-old Texan was found dead at home with a distended bladder full of urine. But a drug screen was clean. So Dr. Dasgupta used a test known as liquid chromatography-mass spectrometry to pinpoint loperamide as the culprit. | In one case at the hospital, opioid abuse was suspected after a 19-year-old Texan was found dead at home with a distended bladder full of urine.
