“Bottoms living on Imodium, is it Safe?”
One of my friends asked that I write a section called “bottoms living on Imodium, is it safe?” Short answer: occasional use at label doses is generally considered low risk. As with all things, in moderation. (and definitely check with your healthcare team)
Imodium (loperamide) is an over-the-counter antidiarrheal medication. It is technically an opioid medication, but at recommended doses, it only impacts the gastrointestinal tract by slowing how digested food moves through the intestines. One of the most common reasons for recreational Imodium use is for long or repeated sessions when trying to keep the rectum clear for a prolonged period of time- “to keep the douche“. Different dosing strategies are used, and generally taking the recommended dose of 8 mg or less per day occasionally is considered safe.
Because each of our GI tracts are different and uniquely impacted by our diets, medications, supplements, and mental health among other factors, the optimal timing and dosing for this medication will vary from person to person. Using the drug for sex can be complicated by ongoing or chronic bowel issues, like constipation, diarrhea, or both. When Imodium use is for bowel issues (rather than sex exclusively), it is helpful to identify the underlying cause, and your healthcare team can help you determine whether symptoms are related to diet, medication, supplements, mental health/stress, medical issues, infections, or other causes. When used to treat GI conditions, like irritable bowel syndrome (IBS), the dose may be higher than 8 mg (under the direction of a healthcare provider). For acute (new, relatively intense) diarrhea, Imodium can be helpful, but if diarrhea is caused by an infection, Imodium can worsen the disease course. It is not recommended for diarrhea lasting more than 2 days or diarrhea associated with a fever- in which case a trip to your favorite PA (or other healthcare provider) is in order.
The recommended dose is 4 milligrams (mg) which is 2 tablets. Another 2 mg (1 tablet) can be taken after each loose stool for a daily maximum of 8 mg (4 tablets). At this dose there are very few side effects, most commonly gas, abdominal cramping, and nausea. Drug concentrations peak at 4-5 hours and then remain for several additional hours after taking the medication. Here’s a resource for more technical information.
Imodium is generally a very safe drug when used as directed, but at high concentrations the drug can accumulate in the body where it can impact the brain causing opioid effects (happiness, relaxation, drowsiness, slowed breathing), but more importantly, can cause significant major, potentially fatal injury to the heart. Seek medical help immediately wth fainting, rapid heartbeat, irregular heart rhythm, chest pain, extreme drowsiness, or slowed breathing.
There’s no clear threshold for how much is too much, but most reports of heart injury are at doses of 60-400 mg (or 30-200 tablets) per day. Most overdose cases are in attempt to reach the opioid effects rather than for sex. These opioid effects, which can be worsened by other drugs with similar effects, can be dangerous and naloxone (Narcan) can reverse sedation and slowed breathing but not cardiac effects. Whenever naltrexone is administered always seek evaluation in the emergency department. Imodium stays in the system longer than Narcan, so the negative effects can return if not addressed. Sometimes people choose not to for fear of repercussions, but keep in mind that Imodium is a legal, over-the-counter medication.
Ongoing use for prolonged periods isn’t recommended by the manufacturer, and I am unaware of any rigorous trials evaluating the effects of ongoing use. At label doses I’m not aware of evidence of dependence, but at high doses tolerance and withdrawal are reported, and escalating doses is what drives the cardiac risk.
