What are amphetamines?
Amphetamines are stimulants. Used properly, they increase
alertness and physical ability. They might be prescribed
to treat:
- narcolepsy (overwhelming sleepiness)
- attention deficit hyperactivity disorder (ADD or
ADHD)
- obesity
- certain forms of depression
- side effects from some medicines.
Examples of prescription amphetamines are Dexedrine,
Desoxyn, and Adderall. Some nonprescription cold medicines
or diet pills contain ephedrine or pseudoephedrine.
Amphetamines can be prescribed in time release forms that
last longer and cause fewer side effects. Doses are
adjusted to offer the most benefit with the fewest side
effects. When prescription amphetamines are taken by mouth
and in low doses, dependence and withdrawal symptoms are not
a high risk.
One of the differences between use and abuse is the reason
why you take the drug. Taking amphetamines prescribed by a
healthcare provider to treat a medical problem is proper
use. Taking any drug to get high is abuse. Drug addiction
is a risk when these medicines are taken at doses higher
than those needed for medical treatment.
Amphetamine pills are sold on the street as "speed" or
"uppers." They are often used in amounts that are much
higher than medical doses. Methamphetamine (also called
meth or ice) is a street drug that is smoked. Its effects
are very strong and last longer than prescription medicines.
Street drugs are often mixed with other drugs and cause
unpredictable effects.
What is amphetamine dependence?
If you are dependent on a drug, you feel a need for the drug
when it is stopped. If you crave the drug, or feel
distressed without it, you are psychologically dependent.
If you have bodily changes such as hot and cold flashes or
tremors when the drug is stopped, you are physically
dependent.
How does it occur?
Amphetamines change body chemistry, especially in the brain.
At first you use the drug because it makes you feel good.
As you become dependent, you use the drug to avoid the
psychological and physical withdrawal symptoms.
Using illegal forms of a drug or taking too much of a
prescribed drug can cause dependence.
You have a higher risk of becoming dependent on drugs if you
have:
- a mental illness such as depression, bipolar
disorder, or antisocial personality disorder
- a family history of drug abuse.
What are the symptoms of dependence?
People who use amphetamines for a long time:
- feel overexcited and nervous
- are irritable and depressed
- can't sleep.
They may also:
- lose their appetite
- lose their sex drive
- feel disoriented
- have learning problems
- take stimulants in larger amounts or over a longer period
than intended
- use the drug throughout the day
- start acting odd, suspicious, dramatic, erratic, or
antisocial or become paranoid
- have problems in social activities and work, such as
missing work, fighting, losing friends
- engage in risky behavior, such as reckless buying sprees
or unsafe sexual practices
- not be able to reduce or stop the use of amphetamines
even though they know the drugs are harmful.
Physical signs of amphetamine use include:
- dilated pupils
- dry mouth and nose
- bad breath
- frequent lip licking.
When people stop taking the drug and the level of it in
the blood drops, there may be withdrawal symptoms such
as:
- sweating or rapid pulse
- increased shakiness
- trouble sleeping
- nausea or vomiting
- hallucinations (seeing, hearing, or feeling things that
are not there)
- jumpiness
- anxiety
- seizures (convulsions)
- increased craving for amphetamines.
How is it diagnosed?
Your healthcare provider will ask about your symptoms and
drug use and examine you. A sample of your urine may be
tested for drug use.
How is it treated?
For any treatment to be successful, you must want to give up
amphetamines. Most amphetamine users who want to quit need
to avoid all stimulants, including caffeine and tobacco.
Withdrawal from long-term amphetamine use causes depression.
Withdrawal is usually not life threatening and does not
cause physically painful symptoms.
Your healthcare provider may prescribe medicine to help you
get through withdrawal, such as:
- antidepressants to help with both depression and drug
craving
- sedatives to treat anxiety or trouble sleeping
- antipsychotics to treat paranoia
- medicines that may help cravings.
You can join a self-help group (for example, Narcotics
Anonymous), a support group, or a therapy group, or you
might be treated in a supervised clinic program. The
healthcare providers and counselors in any treatment
program will work with you to help you have a life free
from amphetamines.
How long do the effects last?
Recovery from amphetamine dependence can be a long-term
process, but your symptoms will generally improve in 1 to 3
months.
How can I take care of myself?
The best way to help yourself is to see your healthcare
provider and stop taking amphetamines.
Changing your lifestyle can also help you to stop using
amphetamines. Make the following a regular part of your
life:
- Exercise 30 minutes 3 times a week.
- Participate in relaxing recreation activities at least
once or twice a week.
- Do relaxation exercises daily.
- Think of good things about your life often.
- Eat healthy meals.
- Get 7 to 9 hours of rest each night.
- Practice deep breathing exercises when you feel
stressed.
- Talk and spend time with friends.
- Listen to music to help you relax.
- Get help at home and at work when the load is too great to
handle.
- Seek professional help to talk through anxiety-producing
life events. Ask for help in developing positive ways to
cope.
