Rapid eye movement sleep behavior disorder responds well to low doses of clonazepam. The treatment of acute and chronic akathisia induced by neuroleptics, also called antipsychotics. Spasticity related to amyotrophic lateral sclerosis. Alcohol withdrawal syndrome

Other
Benzodiazepines, such as clonazepam, are sometimes used for the treatment of mania or acute psychosis-induced aggression. In this context, benzodiazepines are given either alone, or in combination with other first-line drugs such as lithium, haloperidol or risperidone. The effectiveness of taking benzodiazepines along with antipsychotic medication is unknown, and more research is needed to determine if benzodiazepines are more effective than antipsychotics when urgent sedation is required. Hyperekplexia
Many forms of parasomnia and other sleep disorders are treated with clonazepam. It is not effective for preventing migraines. Contraindications

Respiratory depression. Adverse effects
In September 2020, the U.S. Food and Drug Administration (FDA) required the boxed warning be updated for all benzodiazepine medicines to describe the risks of abuse, misuse, addiction, physical dependence, and withdrawal reactions consistently across all the medicines in the class. Common
Sedation
Euphoria
Motor impairment

Less common
Confusion
Irritability and aggression
Psychomotor agitation
Lack of motivation
Loss of libido
Impaired motor functionImpaired coordination
Impaired balance
Dizziness
Cognitive impairmentsHallucinations. Short-term memory loss
Anterograde amnesia (common with higher doses)
Some users report hangover-like symptoms of drowsiness, headaches, sluggishness, and irritability upon waking up if the medication was taken before sleep. This is likely the result of the medications long half-life, which continues to affect the user after waking up. While benzodiazepines induce sleep, they tend to reduce the quality of sleep by suppressing or disrupting REM sleep.
A fecal impaction is a solid, immobile bulk of feces that can develop in the rectum as a result of chronic constipation. A related term is fecal loading which refers to a large volume of stool in the rectum of any consistency. Fecal impaction is a common result of neurogenic bowel dysfunction and causes immense discomfort and pain. Treatment of fecal impaction includes laxatives, enema, and pulsed irrigation evacuation (PIE). Signs and symptoms
Symptoms include chronic constipation. There can be fecal incontinence and paradoxical overflow diarrhea (encopresis) as liquid stool passes around the obstruction. Complications may include necrosis and ulcers of the rectal tissue. Abdominal pain and bloating could also be present depending on the severity of the condition. Loss of appetite can also occur. Causes
There are many possible causes; for example, physical inactivity, not eating enough fiber, dehydration, and holding in bowel movements. Medications such as opioid pain relievers (fentanyl, buprenorphine, methadone, codeine, oxycodone, hydrocodone, morphine, hydromorphone, etc.) and certain sedatives that reduce intestinal movement may cause fecal matter to become too large, hard and/or dry to expel. Specific conditions, such as irritable bowel syndrome, certain neurological disorders, paralytic ileus, gastroparesis, diabetes, dehydration, enlarged prostate gland, distended colon, ingested foreign object, inflammatory bowel diseases such as Crohns disease and colitis,  and autoimmune diseases such as amyloidosis, celiac disease, lupus, and scleroderma can cause constipation. Hypothyroidism can cause chronic constipation because of sluggish, slower, or weaker colon contractions. Iron supplements or increased blood calcium levels are also potential causes.
