Potential Adverse Effects of Amphetamine Treatment on Brain and Behavior: A Review

Your body and mind will need to adjust to functioning without the drug. It is possible to build up a tolerance to amphetamines, which means the person using the drug needs to take larger doses to achieve the same effect. You can still be in danger even if not all overdose symptoms are present.

• This stimulant curbs impulsivity and improves attention and focus.
• The ramifications of amphetamine toxicity and overdose are profound, contributing to substantial morbidity and mortality rates.
• These drugs include pseudoephedrine,21 mebeverine,22 metoprolol,23 tetracaine,24 dimethylamylamine,25 aripiprazole,26 and ranitidine.27 Thus, clinicians should not rely on drug metabolite testing alone to make a diagnosis of amphetamine toxicity.

These actions further promote cytoplasmic accumulation of monoamines, which can then be transported into the synapse. Amphetamines are used for fatigue, appetite suppression, and narcolepsy treatment. Patients experiencing amphetamine toxicity thus often present with anorexia, dehydration, weight loss, and insomnia. Patients may be highly agitated, even to the point of risking the safety of healthcare staff and themselves. Patients should be asked what drug(s) they used, the route of administration they utilized, and the duration of their drug use.

How we reviewed this article:

As with similar stimulants, methamphetamine is most often used in a “binge and crash” pattern. Because the pleasurable effects disappear even before the drug concentration in the blood falls significantly, users try to maintain the high by bingeing on the drug. In some cases, abusers indulge in a form of bingeing known as a “run,” forgoing food and sleep while continuing abuse for up to several days. People may become extremely paranoid, violent, and out of control.

• Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines.
• Maximum plasma concentration for Adderall XR is achieved about 6 h after ingestion 15.
• It has been suggested that the accumulation of metabolites may contribute to generation of psychotic symptoms 200 and to general amphetamine neurotoxicity 201.

• These drugs were also used medically to treat obesity and depression.
• The dose of this medicine will be different for different patients.
• Even recently, soldiers have been given amphetamines for endurance in battle.

This frequency of amphetamine use parallels regional differences in the prevalence estimates of ADHD 33. In 2004, 70% of the stimulant prescriptions for children in Western Australia were for d- amphetamine. However, as methylphenidate was approved for government subsidies in late 2005, its use has probably since increased 33.

• To diagnose amphetamine toxicity, other toxicities need to be explored, including toxicities to cocaine, methylxanthine, phencyclidine, and other sympathomimetics.
• It is characterized by excessive daytime sleepiness, cataplexy, and hypnagogic hallucinations.
• As a rough guide, methamphetamines can be detected in the blood around 4 to 8 hours after use, and in the urine for around 2 to 5 days after use.
• In most cases, it is difficult to determine their quality and purity – they can be a mix of drugs, binding agents, caffeine and sugar.

Are amphetamines a controlled substance?

(Dopamine is a neurotransmitter, a substance that helps nerve cells communicate.) This effect is the likely cause of mood elevation. MDMA differs from other amphetamines in that it also interferes with the reuptake of serotonin (another neurotransmitter) in the brain. Amphetamine users frequently develop dependence, often referred to as a substance use disorder.

What other medications interact with amphetamines?

Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body. It is very important that your doctor check your or your child’s progress at regular visits to make sure the medicine is working properly. Blood tests and blood pressure tests may be needed to check for unwanted effects. Your doctor may occasionally stop treatment to check symptoms of ADHD. The dose of this medicine how long do amphetamines stay in urine will be different for different patients.

Regular use of amphetamines, especially when the drug is smoked or injected, can quickly cause addiction. In a 2017 survey of Ontario students in grades 7 to 12, about two percent of students reported non-medical use of ADHD stimulant drugs in the past year. Methamphetamine can be ingested orally, insufflated nasally, smoked, or injected intravenously.

• In one of the longest prospective studies, which included a no drug comparison, 370 ADHD children from 7.0 to 9.9 years of age, enrolled in the Multimodal Treatment Study of ADHD (MTA), were contrasted according to the use and continuity of stimulant treatment 69.
• Long-term use of illegal amphetamines can lead to serious problems, including changes to the brain, cardiovascular damage, malnutrition and anxiety and paranoia.
• Amphetamine may cause blood circulation problems that can cause numbness, pain, or discoloration in your fingers or toes.
• Recent reports have added some clarity to the issue, and the NIH National Toxicology Program concluded that there was concern for neurobehavioral developmental toxicity from amphetamines 23.
• In some cases, abusers indulge in a form of bingeing known as a “run,” forgoing food and sleep while continuing abuse for up to several days.

Seizures should initially be treated with parenteral benzodiazepines. Barbiturates and propofol may be added for further seizure control. Phenytoin, fosphenytoin, and valproic acid should be avoided due to their ineffectiveness in aborting toxicologic seizures. Naltrexone has been evaluated for this indication based on its ability to decrease the effects of the dopamine reward system. Some studies have shown promising results for naltrexone.3233 In contrast, others have shown a lack of appreciable effects on cravings or amphetamine use.343536 However, many of these studies were conducted on animals.

The estimated annual prevalence of a stimulant use disorder involving amphetamines is 0.2 percent among U.S. adults, according to the DSM-5. In certain cases, psychotic symptoms can last for months or years after methamphetamine abuse has ceased. Stress has been shown to precipitate spontaneous recurrence of methamphetamine psychosis in formerly psychotic methamphetamine abusers. Methamphetamine was developed early in the 20th century from its parent drug, amphetamine, and was used originally in nasal decongestants and bronchial inhalers.
