How Lomotil (diphenoxylate / atropine) works
Lomotil (diphenoxylate / atropine) is a combination of two medications that work together to treat diarrhea.
- Diphenoxylate is an opioid. It works by binding to specific proteins in your gut to help control and slow down gut movement.
- Atropine is an anticholinergic that's used to prevent misuse of Lomotil (diphenoxylate / atropine). It blocks the activity of a natural chemical in your body called acetylcholine, which can cause bothersome side effects like nausea if Lomotil (diphenoxylate / atropine) is taken too often.

Risks and warnings for Lomotil (diphenoxylate / atropine)
Lomotil (diphenoxylate / atropine) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Breathing problems
- Risk factors: Children younger than 6 years old | Taking other medications that cause breathing problems
There have been cases of children having serious breathing problems or a coma after taking Lomotil (diphenoxylate / atropine). These effects can cause permanent brain damage or death. Children younger than 6 years old are at the greatest risk. Keep this medication safely stored and out of reach of children.
Overdose
- Risk factors: Taking higher doses of Lomotil (diphenoxylate / atropine)
Typical prescribed doses of Lomotil (diphenoxylate / atropine) for diarrhea don’t usually lead to addiction or misuse. However, higher doses can cause a life-threatening overdose. Symptoms include slow breathing, coma, extreme fatigue, slurred speech, and a rapid heartbeat. Slow breathing can appear up to 30 hours after taking the medication. Seek medical help immediately if you experience any of these symptoms.
Sleepiness and dizziness
- Risk factors: Drinking alcohol | Taking other medications that make you sleepy
Lomotil (diphenoxylate / atropine) can make you feel sleepy or dizzy and it can lower your ability to focus, think, and react. Drinking alcohol and taking other medications that also cause sleepiness ((e.g., benzodiazepines, muscle relaxants, opioids) raises this risk. Avoid activities that require you to be alert, such as driving a car or operating machinery, until you know how this medication affects you.
Dehydration
- Risk factors: Not taking in enough fluids | Severe diarrhea
Diarrhea can make you dehydrated. Make sure you get enough fluids when you have diarrhea and that you're properly hydrated when you take Lomotil (diphenoxylate / atropine). Talk to your prescriber or pharmacist if you have additional questions.
Serious bowel problems
- Risk factors: Having diarrhea caused by bacteria | Ulcerative colitis (UC)
In some cases, Lomotil (diphenoxylate / atropine) can lead to serious bowel problems. Lomotil (diphenoxylate / atropine) should never be used to treat diarrhea caused by bacteria. The medication slows down your gut, which can cause bacteria to grow more in your intestines. If you have worsening diarrhea after taking Lomotil (diphenoxylate / atropine), speak with your prescriber.
People who have ulcerative colitis (UC) should also be careful when taking Lomotil (diphenoxylate / atropine). It's rare, but this medication can cause a serious, life-threatening swelling of your large intestines called toxic megacolon. Let your prescriber know if you have symptoms such as a fever, high heart rate, dehydration, or low blood pressure.
