Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Alcohol and other medications that cause drowsiness: Do not consume alcohol while taking this medication, as this may lead to dangerous side effects. Other medications that cause drowsiness or slow down your breathing (e.g., antidepressants, sleeping pills, anxiety medications) should be avoided if possible as additive side effect may occur and can be dangerous and possible fatal.
Behavioural and mood changes: This medication may cause mood and psychiatric changes, including aggressiveness, confusion, anxiety, restlessness, and memory lapses. Tell your doctor as soon as possible if you notice any unusual changes in your behaviour.
Body temperature: This medication may decrease the amount of sweat that is created in an effort to control body temperature. People who exercise vigorously, are exposed to extreme heat, are dehydrated, or are taking other anticholinergic medications (e.g., benztropine, oxybutynin) are more at risk. Contact your doctor as soon as possible if you feel very hot and are unable to cool.
Exposure to extreme heat or being in a hot environment for a long period of time can result in severe overheating that can be fatal.
Breathing problems: This medication can cause the mucus and secretions in the lungs to become dry and difficult to cough up. If you have asthma or chronic obstructive pulmonary disease (COPD; emphysema, chronic bronchitis) you may experience increased difficulty breathing. If you have breathing problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Constipation/intestinal blockage: Clidinium slows down the speed at which things travel through the digestive system and may cause constipation. If constipation develops, talk to your doctor or pharmacist as soon as possible.
Dental problems: Clidinium can cause dry mouth, which increases the risk of dental disease. You should see your dentist regularly and let your dentist know about this and any other medications you may be taking.
Dependence and withdrawal: Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with benzodiazepines such as chlordiazepoxide - clidinium. Severe withdrawal may occur if the dose is significantly reduced or suddenly discontinued. These symptoms include seizures, irritability, nervousness, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, memory impairment, headache, muscle pain, extreme anxiety, tension, restlessness, and confusion. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms.
Depression: Chlordiazepoxide may cause depression or make the symptoms of depression worse. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.
Drowsiness/reduced alertness: Because chlordiazepoxide - clidinium may cause drowsiness and sedation, do not engage in activities that require mental alertness, judgment, and physical coordination (such as driving or operating machinery) while taking this medication. This is particularly true when first starting the medication and until you have established that chlordiazepoxide - clidinium does not affect you this way. Alcohol ingestion can increase the drowsiness effects and should be avoided.
Falls and fractures: Chlordiazepoxide - clidinium can cause drowsiness or dizziness that can affect your balance and increase your risk of falling. This can result in fractures or other injuries. Your risk of falls is increased if you drink alcohol or take sedatives while taking this medication, if you are elderly or if you have a condition that causes weakness or frailty.
Glaucoma: This medication may make the symptoms of glaucoma worse. If you have glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
High blood pressure: High blood pressure can be aggravated by this medication. If you have a history of high blood pressure or are taking medications for high blood pressure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Myasthenia gravis: Chlordiazepoxide - clidinium may cause symptoms of myasthenia gravis to worsen. If you have myasthenia gravis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Performing activities while not fully awake: People taking chlordiazepoxide - clidinium may perform activities such as sleepwalking, driving, preparing and eating food, and making phone calls while not fully awake and are unaware of their actions. The next morning, they may not remember what happened. This may be more likely to occur if you use alcohol or other sedative medications. If you discover this has happened to you, contact your doctor immediately.

If you have prostate enlargement or another problem involving the prostate gland, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
