Amphetamines - Guidelines for Using Amphetamines

Type of Drug:

Central nervous system stimulants: “Bennies,” “dexies,” “speed”, or “crystal.”

How the Drug Works:

These synthetic drugs are a stronger form of the natural body stimulant adrenaline. They work by altering natural chemicals (neurotransmitters) in the brain and can affect other body systems (eg, circulatory system) in high doses.

Uses:

Indicated as an integral part of a total treatment program of attention deficit disorder with hyperactivity that includes other remedial measures (psychological, educational, social) for a stabilizing effect in children 3 to 16 years of age with a behavioral syndrome characterized by moderate to severe distractibility, short attention span, hyperactivity, emotional 13 ability, and impulsivity.

To improve wakefulness in patients with excessive daytime sleepiness associated with narcolepsy.

Methamphetamine only: For short term (eg, a few weeks) use in a weight reduction program based on caloric restriction, for patients who have failed alternative therapy (eg, repeated diets, group programs, other drugs).

Unlabeled Uses: Dextroamphetamine has been used to treat cocaine dependence and autism.

Precautions:

Use with caution in the following situations: High blood pressure Turreted syndrome

Abuse: Amphetamines have a high potential for abuse. Use in weight reduction programs only when alternative therapy (diets, group programs, other drugs) has been ineffective. Use for prolonged periods may lead to drug dependence.

Attention deficit disorders: Drug treatment is not indicated in all cases. The decision to use amphetamines depends on the chronicity and severity of the child’s symptoms and appropriateness for his/her age. When symptoms are associated with acute stress reactions, treatment with amphetamines is usually not indicated.

Chronic intoxication: Severe skin rash, marked sleeplessness, irritability, hyperactivity, personality changes, disorganization of thoughts, poor concentration, hallucinations, and compulsive behavior often occur. The most severe side effect of chronic intoxication is psychosis, often indistinguishable from paranoid schizophrenia.

Diabetes: Insulin requirements may be altered with the use of amphetamines and diet restriction.

Do not use: Do not use to combat fatigue or to replace rest.

Drug dependence: Tolerance, extreme dependence and severe social disability have occurred with amphetamine abuse. Patients may gradually increase the dosage to many times that recommended. Abrupt discontinuation following a long period of using high doses results in extreme fatigue, mental depression, and changes in sleep habits.

Pregnancy: Adequate studies have not been done in pregnant women, or animal studies may have shown a risk to the fetus. Birth defects have been reported with amphetamine use in pregnancy. Usually If clearly needed and potential benefits outweigh the possible hazardsto the fetus. Infants born to mothers dependent on amphetamines have an increased risk of premature delivery and low birth weight may experience symptoms of amphetamine withdrawal demonstrated by restlessness including agitation and weakness.

Breastfeeding: Amphetamines appear in breast milk. Discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. Consult your doctor before you begin breastfeeding.

Children: Long-term effects in children have not been well established.

Amphetamines are not recommended in children younger than 3 years of age. Do not use methamphetamine as a weight loss medication in children younger than 12 years of age. Extended-release amphetamine mixture capsules are indicated for children 6 years of age and older. Effects of extended-release amphetamine mixture capsules in children 3 to 5 years of age have not been studied. In psychotic children, amphetamines may worsen symptoms of behavior disturbance and thought disorder. Amphetamines may precipitate or worsen Tourette syndrome. Monitor growth during treatment. Chronic administration may be associated with growth inhibition.

Tartrazine: Some of these products may contain tartrazine dye (FD&C Yellow No.5), which can cause allergic reactions in certain individuals. Check package labeling when available or consult your doctor or pharmacist.

Pemoline - Guidelines for Using Pemoline - Uses and Benefits

Type of Drug:

Central nervous system stimulant.

How the Pemoline Product Works:

Pemoline stimulates the central nervous system. How it does this is not fully understood.

Uses of The Pemoline:

To aid in treatment of children with behavior problems (attention deficit disorder) characterized by hyperactivity, moderate to severe distractibility, short attention span, impulsive behavior, and extreme mood changes.

Unlabeled Uses: Occasionally doctors may prescribe pemoline for narcolepsy (irresistible periods of sleep lasting less than 15 minutes during normal waking hours) and excessive daytime sleepiness.

Precautions:

  • Drug dependence: The similarity of pemoline to other brain stimulants with known dependence liability suggests that psychological and physical dependence might also occur. There have been isolated reports of temporary psychotic symptoms occurring in adults following the long-term misuse of excessive doses. Pemoline should be given with caution to emotionally unstable patients who may increase the dosage on their own initiative.
  • CNS stimulants: CNS stimulants, including pemoline, have been reported to precipitate motor and phonic tics, and Tourette syndrome. Therefore, clinical evaluation for tics and Tourette syndrome in children and their families should precede use of stimulant medications.
  • Potential liver toxicity: Report any unexplained appetite loss, nausea, vomiting, general body discomfort, weakness, or yellowing of the skin or eyes to your doctor.
  • Total treatment program: Pemoline therapy should be part of a total treatment program that includes psychological, educational psychological, educational, and social measures.
  • Pregnancy: There are no adequate and well-controlled studies in pregnant women. Use only if clearly needed and the potential benefits to the mother outweigh the possible hazards to the fetus.
  • Breastfeeding: It is not known if pemoline appears in breast milk. Consult your doctor before you begin breastfeeding.
  • Children: Safety and effectiveness in children less than 6 years of age have not been established. Pemoline use may worsen symptoms of behavior disturbance and thought disorder in psychotic children. Aggravation of Tourette syndrome and seizure disorders have been reported after starting pemoline therapy. Chronic administration of stimulants to children may be associated with growth inhabiting. Therefore, growth must be monitored during treatment. Long-term effects in children have not been well established. Treatment is not indicated in all cases of attention deficit disorder with hyperactivity. The decision to prescribe pemoline should depend on the assessment of the severity of the child’s symptoms for his or her age, and not depend solely on the presence of one or more of the behavioral characteristics.
  • Lab Tests: Lab tests will be required before and during pemoline therapy. Tests may include periodic liver function evaluation.

Drug Interactions:

Tell your doctor or pharmacist if you are taking or planning to take any over-­the-counter or prescription medications or dietary supplements while taking pemoline. Doses of one or both drugs may need to be modified or a different drug may need to be prescribed. Decreased seizure thresh­old has been reported in patients also taking anti epileptic medications (eg, phenytoin).

Side Effects:

Every drug is capable of producing side effects. Many pemoline users experience no, or minor, side effects. The frequency and severity of side effects depend on many factors including dose, duration of therapy, and individual susceptibility. Possible side effects include:

  • Digestive Tract: Nausea; stomachache; loss of appetite.
  • Nervous System: Sleeplessness; seizures; hallucinations; dizziness; drowsiness; increased irritability; involuntary movements of tongue, face, arms, and legs; Tourette syndrome; depression; headache; abnormal eye movements.
  • Other: Rash; yellowing of skin or eyes; dark urine; abnormal liver function tests; weight loss; liver dysfunction.

Guidelines for Use:

  • Do not use pemoline until you have discussed with your doctor the risks and benefits of treatment. A written informed consent is required before beginning therapy.
  • Dosage is individualized. Take exactly as prescribed. Administer as a single dose each morning.
  • Do not stop taking or change the dose unless directed your doctor.

If more than one dose is missed or it is necessary to establish a new dosage schedule, contact your doctor or pharmacist.
  • Clinical improvement with pemoline is gradual. Significant benefit may not be evident until after 3 to 4 weeks of therapy.
  • Because of its association with life-threatening liver failure, pemoline should not ordinarily be considered as first-line drug therapy for attention deficit hyperactivity disorder (ADHD).
  • May cause drowsiness or dizziness. Use caution while driving or performing other tasks requiring alertness, coordination, or physical dexterity until tolerance is determined.
  • Inform your doctor if you are pregnant, become pregnant, are planning to become pregnant, or are breastfeeding.
  • Notify your doctor immediately if you experience darkening of urine, appetite loss, general body discomfort, nausea, vomiting, yellowing of the skin or eyes, or uncontrolled movement.
  • Notify your doctor if sleeplessness occurs and is bothersome.
  • Chronic use may suppress growth in children.
  • Your doctor may interrupt treatment occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy.
  • Pemoline therapy should be stopped if no benefit is noted after 3 weeks of taking the maximum do.
  • Lab tests will be required to monitor therapy. Be sure to keep appointments.
  • Store at room temperature (59° to 86°F).
