Chlordiazepoxide may increase the risk of serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take certain opiate medications for cough such as codeine (in Triacin-C, in Tuzistra XR) or hydrocodone (in Anexsia, in Norco, in Zyfrel) or for pain such as codeine (in Fiorinal), fentanyl (Actiq, Duragesic, Subsys, others), hydromorphone (Dilaudid, Exalgo), meperidine (Demerol), methadone (Dolophine, Methadose), morphine (Astramorph, Duramorph PF, Kadian), oxycodone (in Oxycet, in Percocet, in Roxicet, others), and tramadol (Conzip, Ultram, in Ultracet). Your doctor may need to change the dosages of your medications and will monitor you carefully. If you take the combination of chlordiazepoxide and clidinium with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care immediately: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
Drinking alcohol or using street drugs during your treatment with the combination of chlordiazepoxide and clidinium also increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol or use street drugs during your treatment.
Why is this medication prescribed?
The combination of chlordiazepoxide and clidinium is used along with other medications to treat peptic ulcers, irritable bowel syndrome (IBS; a condition that causes stomach pain, bloating, constipation, and diarrhea), and enterocolitis (swelling in the intestines). Chlordiazepoxide is in a class of medications called benzodiazepines. It works by decreasing abnormal electrical activity in the brain. Clidinium is in a class of medications called anticholinergics. It helps to decrease stomach spasms and cramps.
How should this medicine be used?
The combination of chlordiazepoxide and clidinium comes as a capsule to be taken by mouth. It usually is taken three or four times a day, before meals and at bedtime. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take chlordiazepoxide and clidinium exactly as directed.
Do not stop taking chlordiazepoxide and clidinium without talking to your doctor. If you suddenly stop taking chlordiazepoxide and clidinium, you may experience withdrawal symptoms such as seizures, shaking, stomach cramps, muscle cramps, depression, vomiting, difficulty falling asleep or staying asleep, and sweats. Your doctor will probably decrease your dose gradually.
Chlordiazepoxide and clidinium may be habit-forming. Do not use more of it, use it more often, or use it in a different way than directed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse chlordiazepoxide and clidinium if you have or have ever had any of these conditions.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with chlordiazepoxide and clidinium and each time you fill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
