Lomotil, a combination of diphenoxylate (an opioid) and atropine (an anticholinergic), is used to treat diarrhea. While it is not considered addictive at prescribed doses for diarrhea, it has a potential for abuse and dependence, particularly when taken in high doses due to the opioid component, diphenoxylate. Here’s a detailed overview:
Addiction Potential
- Low Risk at Therapeutic Doses: At recommended doses (e.g., 2 tablets four times daily, max 20 mg diphenoxylate/day), Lomotil does not typically cause addiction. Diphenoxylate lacks morphine-like effects at these levels, and atropine is included to deter abuse by causing unpleasant side effects (e.g., dry mouth, blurred vision) if taken excessively.
- High-Dose Abuse: At very high doses (100–300 mg/day, equivalent to 40–120 tablets), Lomotil can produce euphoria and codeine-like effects, leading to physical dependence and opioid withdrawal symptoms upon cessation. Such doses far exceed therapeutic recommendations.
- Dependence Reports: Studies, particularly from India, document cases of Lomotil dependence, with 41 patients in one study using it as a primary substance of abuse, often taking 3–250 tablets daily (median 25). Users were typically males, employed, and from rural areas, often initiating use to relieve opioid withdrawal, as a cheap opioid substitute, or due to curiosity.
- Opioid Similarity: Diphenoxylate is chemically related to meperidine (a narcotic), and its abuse potential is similar to other opioids like Demerol. It can be used as a substitute by opioid-dependent individuals when other drugs are unavailable.
Signs of Abuse and Dependence
- Behavioral Signs: Taking more than prescribed, seeking multiple prescriptions, or using Lomotil for non-medical reasons (e.g., euphoria).
- Physical Signs: Tolerance (needing higher doses for effect), withdrawal symptoms (e.g., stomach cramps, nausea, vomiting, diarrhea, anxiety, muscle aches, insomnia, sweating) when stopping use.
- Psychological Dependence: Craving Lomotil or using it to manage stress or opioid withdrawal.
Risks of Abuse
- Overdose: High doses can cause serious effects, including respiratory depression, coma, or death, especially in children. Overdose symptoms may appear up to 12 hours after ingestion and include weakness, blurred vision, slurred speech, fast heartbeat, slowed breathing, or seizures.
- Atropine Toxicity: Excessive intake leads to atropine-related side effects like hyperthermia, tachycardia, urinary retention, and hallucinations.
- Health Complications: Chronic abuse may cause dehydration, electrolyte imbalances, toxic megacolon, or bacterial overgrowth due to slowed gut motility.
- Interactions: Combining Lomotil with alcohol, sedatives, or other CNS depressants increases risks of sedation and respiratory depression.
Management and Treatment
- Medical Supervision: Abruptly stopping Lomotil after high-dose use can cause severe withdrawal symptoms. Gradual tapering under medical supervision is recommended.
- Rehabilitation: Drug rehab programs, like those offered by Talbott Recovery, address physical detox and psychological aspects of addiction through cognitive behavioral therapy and holistic approaches.
- Professional Help: Consult a physician or addiction specialist to assess dependence and underlying causes. Mental health counseling is advised if abuse is intentional or linked to self-harm.
- Emergency Response: For suspected overdose, call emergency services (911) or the Poison Help hotline (1-800-222-1222) immediately. Naloxone may be used to reverse opioid effects in acute cases.
Precautions
- Follow Prescriptions: Do not exceed the prescribed dose (typically 20 mg diphenoxylate/day for adults).
- Storage: Keep Lomotil out of reach of children, as overdose can be fatal. Store at room temperature (below 77°F/25°C).
- Avoid Contraindications: Not for use in children under 6, or in cases of bacterial diarrhea (e.g., C. difficile), obstructive jaundice, or hypersensitivity to diphenoxylate/atropine.
- Special Populations: Use cautiously in pregnancy (FDA Category C) or breastfeeding, as risks are unclear. Consult a doctor.
Context of Misuse
Lomotil’s easy availability (prescription in some countries, over-the-counter in others) contributes to its misuse, especially in regions like India and Thailand, where regulatory controls may be lax. Its low cost and opioid effects make it attractive to opioid-dependent individuals.
If you’re concerned about Lomotil use (e.g., a friend’s behavior), encourage medical consultation to assess dependency and explore safer alternatives. For immediate concerns about overdose, seek emergency care. Addiction treatment centers can provide comprehensive support for recovery.
