Common Questions about Diphenoxylate-Atropine


Is diphenoxylate-atropine an opioid?

Diphenoxylate, which is one of the active ingredients in Lomotil, is an opioid. It is the same class of drugs as morphine, oxycodone, hydrocodone, and fentanyl. Small doses of diphenoxylate and atropine are used to treat diarrhea. This medicine does not have pain-relieving effects like other opioids. However, like all opioids, there is a risk of abuse and addiction. Diphenoxylate and atropine is therefore classified as a Schedule V controlled substance (other opioids like morphine are Schedule II drugs).



Is diphenoxylate-atropine better than Imodium?

Both diphenoxylate and atropine (Lomotil) and loperamide (Imodium) can effectively treat diarrhea. However, the main difference between these anti-diarrheals is that Imodium is available over-the-counter while Lomotil is a prescription medication and controlled substance.



How many Lomotil tablets can I take in a day?

The maximum dose of diphenoxylate and atropine (Lomotil) is two tablets four times a day. This is a total of 8 tablets in a day. Each tablet contains diphenoxylate 2.5 mg. The diphenoxylate maximum daily dose is therefore 20 mg.



What happens if you take too much Lomotil?

Taking too much diphenoxylate and atropine (Lomotil) can lead to serious and potentially life-threatening complications including respiratory depression, coma, and death. Seek emergency medical care if you or a loved one has overdosed on this medicine.



Can you become addicted to Lomotil?

Lomotil is a Schedule V controlled substance, meaning it has a lower potential for abuse and addiction than other opioids, many of which are Schedule II drugs. However, long-term use of Lomotil can lead to opioid withdrawal symptoms if the medicine is stopped suddenly. Seek medical help if you experience symptoms like anxiety, restlessness, irritability, sweating, chills, or widening of the pupils after stopping Lomotil after prolonged use.
