Anxiety nightmares

The most common side effect of pentazocine is sedation resulting from an interaction with the K-receptor. Also observed are sweating, dizziness, psychotomimetic effects, anxiety, nightmares, and headache. Nausea and vomiting are less frequent than with morphine. Respiratory depression and increased heart rate, body temperature, and blood pressure accompany overdose. Naloxone is effective in reducing the respiratory depression but requires the use of higher doses than for morphine overdose.

Bupropion causes insomnia, nightmares, decreased appetite, anxiety, and tremors, but the most concerning adverse effect is seizures. Because of the risk for seizures, patients who should not receive the drug include those with a CNS lesion or those with a history of seizures, head trauma, or bulimia. The daily dose of bupropion should not exceed 450 mg/day, and any single dose of the immediate-release formulation should not exceed 150 mg/day Occurrences of insomnia and/or nightmares often respond to moving the last daily dose from bedtime to late afternoon.7,9,22,23... 

BZ dependence is defined by the appearance of a predictable withdrawal syndrome (i.e., anxiety, insomnia, agitation, muscle tension, irritability, nausea, malaise, diaphoresis, nightmares, depression, hyperreflexia, tinnitus, delusions, hallucinations, and seizures) upon abrupt discontinuation.

Although we are focusing on the primary sleep disorders, sleep disturbance quite often occurs as a symptom of another illness. Depression, anxiety, and substance abuse can impair the quality of sleep, though in the setting of chronic insomnia, other psychiatric disorders account for less than 50% of cases. Nightmares are a frequent complication of post-traumatic stress disorder (PTSD), and pain, endocrine conditions, and a host of medical illnesses can produce sleep problems. Thus, when discussing insomnia or hypersomnia, we are well advised to remember that these can be either a symptom of a psychiatric syndrome, a medical illness, or a sleep disorder.

In particular, individuals taking nitrazepam (Mogadon) often report an increase in the incidence of nightmares, especially during the first week of use. Flurazepam (Dalmane, Novoflupam, Somnol) also occasionally causes an increase in nightmares, as well as anxiety, irritability, tachycardia, sweating, and garrulousness. 

Although L-dopa can increase dopamine levels in the brain, its effectiveness decreases across time, such that larger and more frequent doses are required for it to be effective. In addition, after only 2-5 years of L-dopa treatment, its duration of effect is reduced. Chronic administration of L-dopa has been reported to produce psychiatric symptoms, such as paranoia, mania, anxiety, depression, hallucinations as well as increased incidence of insomnia and nightmares (92). It is not clear whether these symptoms are associated with chronic L-dopa therapy or disease course, since the two are temporally related (94). Chronic L-dopa therapy may also produce a state where patients response to administration fluctuates, such that they experience an on/off phenomena of L-dopa s effects. Additional symptoms of dyskinesias, e.g., involuntary twisting and writhing, are associated with this on/off phenomenon. Consequently, treatment with L-dopa is typically delayed until other treatments are no longer effective.
