Insomnia dextroamphetamine

The side effects of dextroamphetamine are comparable to other stimulants. Patients may experience insomnia, poor appetite, weight loss, and occasional nausea and diarrhea. Taking the medication just before meals helps to minimize the nausea and diarrhea. To avoid insomnia, dextroamphetamine should rarely be taken any later than 6 PM. 

The acute effects of psychomotor stimulant overdoses are related to their CNS stimulant properties and may include euphoria, dizziness, tremor, irritability, and insomnia. At higher doses, convulsions and coma may ensue. These drugs are cardiac stimulants and may cause headache, palpitation, cardiac arrhythmias, anginal pain, and either hypotension or hypertension. Dextroamphetamine produces somewhat less cardiac stimulation. Chronic intoxication, in addition to these symptoms, commonly results in weight loss and a psychotic reaction that is often diagnosed as schizophrenia. 

The primary drug therapies are psychostimulants which are indicated for both emotional based sleep disorders (i.e., narcolepsy) as well as ADHD. The drugs of choice are Ritalin (methylphenidate), dextroamphetamine or Cylert (pemoline), all CNS stimulants that effect the monoamine systems. The current therapies provide symptomatic relief but the current medications are not without side effects, including abuse potential, cardiovascular effects, insomnia, appetite suppression, head and stomach aches, crying and nervous mannerisms. 

Symptoms of dextroamphetamine abuse include insomnia, irritability, hyperactivity, and psychosis. Psychosis is characterized by radical changes in personality, impaired functioning, and a distorted sense of reality. Hallucinations, delusions, and feelings of paranoia are also common features of psychosis. 

Stimulants have been used as antidepressants for many years, especially dextroamphetamine (Dexedrine) and methylphenidate (Ritalin). They have the side effects of anxiety, insomnia, agitation, and appetite suppression. They can be quite effective antidepressants but are now usually reserved for medically ill patients such as those who have had a stroke and those unresponsive to other antidepressants. 

Dextroamphetamine is a sympathomimetic amine that is used in narcolepsy and in attention-deficit disorder (ADD) in children. Dextroamphetamine releases norepinephrine and, in high doses, also dopamine. It is absorbed from the GI tract, metabolized in the liver, and excreted unchanged in the urine. Acidification of urine shortens amphetamine s half-life, whereas alkalinization of urine prolongs it. The accumulation of hydroxy metabofite of amphetamine has been thought to cause amphetamine-induced psychosis. Therapeutic doses of amphetamine may cause insomnia, tremor, and restlessness, and toxic doses of amphetamine may cause mydriasis, hypertension, and arrhythmia. Chlor-promazine is an excellent antidote in amphetamine toxicity. 

Sometimes doctors prescribe methylphenidate (Ritalin) or dextroamphetamine (Dexedrine) to treat a mood disorder called dysthymia that is less severe, but more chronic, than major depression. They work more quickly than antidepressants to pep you up, increasing energy and facilitating attention and concentration. Common side effects include nervousness, insomnia, constipation, headache, and changes in heart rate.
