Nightmares tremors

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... 

Giddiness, tension, anxiety, jitteriness, restlessness, emotional lability, excessive dreaming, insomnia, nightmares, headaches, tremor, withdrawal and depression, bursts of slow waves of elevated voltage in EEC, especially on over-ventilation, drowsiness, difficult concentration, slowness on recall, confusion, slurred speech, ataxia, generalized weakness, coma, with absence of reflexes, Cheyne-Stokes respirations, convulsions, depression of respiratory and circulatory centers, with dyspnea, cyanosis, and fall in blood pressure. 

Animals self-administer cathinone in a pattern common to abuses of monoamine stimulants such as cocaine (Woolverton and Johanson 1984). Cathinone can induce a conditioned place preference in rats (Schechter 1991). Withdrawal symptoms of khat include lethargy, depression, nightmares, and mild tremor (Kalix 1994). /V-methylated cathinone (methcathinone) is more potent, and has become available on the illegal market. It was subsequently scheduled as a controlled substance (Glennon et al. 1995). 

Adverse reactions include the following anorexia, apprehension, body/joint pain, chest pains, confusion, confusional states/memory impairment, congestion, constipation, coordination disorders, cramps/pain, depression, diarrhea, dreaming/nightmares, dry mouth, dysesthesia, euphoria, Gl pain, GU complaints, headache, heartburn, insomnia, irritability, lack of concentration, nausea, nervousness, palpitations, paresthesia, relaxed feeling, restlessness, tachycardia, taste alterations, tinnitus, tiredness, tremor, vomiting, weakness. 

Tremors of the hands and sleep disturbances in the form of vivid dreams, nightmares, and insomnia have been reported in association with the use of amiodarone. Ataxia, staggering, and impaired walking have been noted. Peripheral sensory and motor neuropathy or severe proximal muscle weakness develops infrequently. Both neuropathic and myopathic changes are observed on biopsy. Neurological symptoms resolve or improve within several weeks of dosage reduction.

Abrupt withdrawal after prolonged therapy may produce effects i ncl udi ng markedly increased dreaming, nightmares or insomnia, tremor, sweating, vomiting, hallucinations, delirium, seizures, and status epilepticus. 

Adverse effects include diarrhoea, nausea, vomiting, vertigo, dizziness, headache, drowsiness, nightmares, asthenia, memory disturbances, depression, confusion, diplopia, tremor and ataxia. 

A patient taking diltiazem developed the signs and symptoms of mania (114) and another developed mania with psychotic features (115). There have also been reports that nifedipine can cause agitation, tremor, belligerence, and depression (116), and that verapamil can cause toxic delirium (117). Nightmares and visual hallucinations have been associated with nifedipine (118). Depression has been reported as a possible adverse effect of nifedipine (119). 

Nervous system stimulation is less frequent than nervous system depression, but when it occurs it causes insomnia, irritability, and tremor nightmares, and hallucinations. In overt intoxication, these effects may be related to anticholinergic effects. In an analysis of 113 200 admissions to a pediatric hospital there were only two patients with excitation, insomnia, visual hallucinations, and seizures, followed by coma (71). 

Adverse effects of ganciclovir involving the central nervous system occur in about 5% of patients and include confusion, seizures, abnormal thinking, psychosis, hallucinations, nightmares, anxiety, tremor, dysesthesia, ataxia, coma, headache, and somnolence (1,5,6). 

In a double-blind, placebo-controlled, crossover study of the use of mexiletine in 20 patients with neuropathic pain with prominent allodynia the dosage was titrated to maximum of 900 mg/day or until dose-limiting adverse effects occurred. Mexiletine produced little beu-eficial effect and the two most common adverse effects were nausea aud sedatiou (12). Other adverse effects that occurred iu oue or two patients each included insomnia, trismus, headache, agitation, nightmares, and tremor. 

Overdose may vary from CNS depression (sedation, apnea, cardiovascular collapse, death) to severe paradoxical reason (hallucinations, tremor, seizures) impaired motor coordination (loss of balance of, blepharospasm [blinking] facial grimace, feeling of heavy leg/stiff neck, involuntary movements), hallucinations, confusion, depression, nightmares, delusions, overstimulation, sleep disturbance, anger occurs in some patients.

A. Amantadine intoxication causes agitation, visual hallucinations, nightmares, disorientation, delirium, slurred speech, ataxia, myoclonus, tremor, and sometimes seizures. Anticholinergic manifestations include dry mouth, urinary retention, and mydriasis. Rarely, ventricular arrhythmias including torsade de pointes (see p 14) and multifocal premature ventricular contractions may occur. Amantadine has also been reported to cause heart failure.
