- USES
-
- This medication is a central nervous system stimulant that increases
- mental alertness and decreases fatigue. It is used to treat narcolepsy (a
- disorder involving uncontrollable desires to sleep or actual sleep attacks
- that occur in a rapid and unpredictable manner) and abnormal behavioral
- syndrome in children (hyperkinetic syndrome or attention deficit disorder).
- The way this medication acts to control abnormal behavioral syndrome in
- children is not clearly understood.
- Methamphetamine is also used as an appetite suppressant during the first
- few weeks of dieting (while you are trying to establish new eating habits).
- It is thought to relieve hunger by altering nerve impulses to the appetite
- control center in the brain. Its effectiveness as an appetite suppressant
- lasts for only short periods (three to 12 weeks), however.
-
- TREATMENT
-
- In order to avoid stomach upset, you can take methamphetamine with food
- or with a full glass of milk or water (unless your doctor directs you to do
- otherwise).
- If this medication is being used to treat narcolepsy or abnormal
- behavioral syndrome in children, the first dose each day should be taken soon
- after awakening. Subsequent doses should be spaced at four- to six-hour
- intervals.
- If this medication has been prescribed as a diet aid, it should be taken
- one hour before each meal.
- The sustained-release form of this medication should be swallowed whole.
- Breaking, chewing, or crushing these tablets destroys their sustained-release
- activity and may increase the side effects.
- In order to avoid difficulty in falling asleep, the last dose of this
- medication each day should be taken four to six hours before bedtime (tablets)
- or ten to 14 hours before bedtime (sustained-release tablets).
- If you miss a dose of this drug, take the missed dose as soon as
- possible, unless it is time for your next dose. In that case, do not take the
- missed dose at all; just return to your regular dosing schedule. Do not
- double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Abdominal cramps, constipation, diarrhea, dizziness, dry mouth, false
- sense of well-being, insomnia, irritability, loss of appetite, nausea,
- restlessness, unpleasant taste in the mouth, or vomiting. These side effects
- should disappear as your body adjusts to the medication.
- In order to prevent constipation, increase the amount of fiber in your
- diet (fresh fruits and vegetables, salads, bran, and whole-grain breads),
- exercise, and drink more water (unless your doctor directs you to do
- otherwise).
- Dry mouth can be relieved by sucking on ice chips or a piece of hard
- candy or by chewing sugarless gum.
- If you feel dizzy, sit or lie down for a while; get up from a sitting or
- lying position slowly, and be careful on stairs.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- blurred vision, confusion, fatigue, headaches, impotence, mental depression,
- palpitations, rash, sweating, tightness in the chest, tremors, or
- uncoordinated movements.
-
- INTERACTIONS
-
- Methamphetamine interacts with several other types of medications:
- 1. Use of it within 14 days of a monoamine oxidase (MAO) inhibitor
- (isocarboxazid, pargyline, phenelzine, tranylcypromine) can result in high
- blood pressure and other side effects.
- 2. Barbiturate medications, phenothiazine tranquilizers (especially
- chlorpromazine), and tricyclic antidepressants can antagonize (act against)
- this medication.
- 3. Amphetamines (such as methamphetamine) can decrease the
- blood-pressure-lowering effects of antihypertensive medication (especially
- guanethidine) and may alter insulin and oral antidiabetic medication dosage
- requirements in diabetic patients.
- 4. The side effects of other central nervous system stimulants, such as
- caffeine, over-the-counter (nonprescription) appetite suppressants, and
- asthma, allergy, cough, sinus, or cold preparations may be increased by
- methamphetamine.
- 5. Acetazolamide and sodium bicarbonate can decrease the elimination of
- methamphetamine from the body, thereby prolonging its action and increasing
- the risk of side effects.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of those listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to methamphetamine or other central nervous system
- stimulants (such as albuterol, amphetamine, dextroamphetamine, ephedrine,
- isoproterenol, metaproterenol, norepinephrine, phenylephrine,
- phenylpropanolamine, pseudoephedrine, and terbutaline).
- * Tell your doctor if you have a history of drug abuse or if you have
- ever had problems with agitation, diabetes mellitus, glaucoma, heart or blood
- vessel disease, high blood pressure, or thyroid disease.
- * Methamphetamine can mask the symptoms of extreme fatigue and can cause
- dizziness. Your ability to perform tasks that require alertness, such as
- driving a car or operating potentially dangerous machinery, may be decreased.
- Appropriate caution should, therefore, be taken.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking this medication.
- * Methamphetamine is related to amphetamine and may be habit-forming when
- taken for long periods of time (both physical and psychological dependence can
- occur). Therefore, you should not increase the dosage of this medication or
- take it for longer than 12 weeks, unless you first consult your doctor. It is
- also important that you not stop taking this medication abruptly; fatigue,
- sleep disorders, mental depression, nausea, vomiting, stomach cramps, or pain
- could occur. Your doctor may, therefore, want to reduce your dosage
- gradually.
- * Some of these products contain the color additive FD&C Yellow No. 5
- (tartrazine), which can cause allergic-type reactions (rash, fainting,
- difficulty in breathing) in certain susceptible individuals.
- * Long-term methamphetamine use in children may cause unwanted effects on
- growth. The benefits and risks of the drug should be thoroughly discussed
- before treatment begins.
- * Be sure to tell your doctor if you are pregnant. Although side effects
- in humans have not been studied, some of the amphetamines can cause heart,
- brain, and biliary tract abnormalities in the fetuses of animals that receive
- large doses of these drugs during pregnancy. Also, tell your doctor if you
- are breastfeeding an infant. Small amounts of this type of drug pass into
- breast milk and can cause excessive stimulation in nursing infants.
