Side effects of Amfetamine in details

infoA side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Clinical Trials Experience with Other Amphetamine Products in Pediatric Patients and Adults with ADHD

Cardiovascular: Palpitations, tachycardia, elevation of blood pressure, sudden death, myocardial infarction. There have been isolated reports of cardiomyopathy associated with chronic amphetamine use.

Central Nervous System: Psychotic episodes at recommended doses, overstimulation, restlessness, irritability, euphoria, dyskinesia, dysphoria, depression, tremor, tics, aggression, anger, logorrhea.

Eye Disorders: Vision blurred, mydriasis.

Gastrointestinal: Dryness of the mouth, unpleasant taste, diarrhea, constipation, other gastrointestinal disturbances. Anorexia and weight loss may occur as undesirable effects.

Allergic: Urticaria, rash, hypersensitivity reactions including angioedema and anaphylaxis. Serious skin rashes, including Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported.

Endocrine: Impotence, changes in libido.

Skin: Alopecia.

Clinical Trials Experience with Amfetamine in Pediatric Patients with ADHD

There is limited experience with Amfetamine in controlled trials. Based on this limited experience, the adverse reaction profile of Amfetamine appears similar to other amphetamine extended-release products. The most common (≥2% in the Amfetamine group and greater than placebo) adverse reactions reported in the Phase 3 controlled study conducted in 108 patients with ADHD (aged 6–12 years) were: epistaxis, allergic rhinitis and upper abdominal pain.

6.2 Postmarketing Experience

The following adverse reactions have been identified during post approval use of other amphetamine products. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Endocrine: frequent or prolonged erections.

Musculoskeletal, Connective Tissue, and Bone Disorders: rhabdomyolysis.

Psychiatric Disorders: dermatillomania.

What is the most important information I should know about Amfetamine?

  • Tell your doctor or dentist that you take Amfetamine before you receive any medical or dental care, emergency care, or surgery.
  • Amfetamine may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Amfetamine with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • Do NOT take more than the recommended dose or use for longer than prescribed without checking with your doctor.
  • Serious effects, including heart attack, stroke, and sudden death, have occurred with the use of stimulant medicines in patients with heart defects or other serious heart problems. If you have a heart defect or other serious heart problem, talk with your doctor about other therapies to treat your condition.

  • Amfetamine may affect growth rate in CHILDREN and teenagers in some cases. They may need regular growth checks while they take Amfetamine.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Amfetamine while you are pregnant. Amfetamine is found in breast milk. Do not breast-feed while taking Amfetamine.

When used for long periods of time or at high doses, Amfetamine may not work as well and may require higher doses to obtain the same effect as when originally taken. This is known as TOLERANCE. Talk with your doctor if Amfetamine stops working well. Do not take more than prescribed.

Some people who use Amfetamine for a long time may develop a need to continue taking it. People who take high doses are also at risk. This is known as DEPENDENCE or addiction. If you suddenly stop taking Amfetamine, you may experience WITHDRAWAL symptoms. These may include severe fatigue and drowsiness.

Amfetamine contraindications

infoContraindication can be described as a special circumstance or a disease or a condition wherein you are not supposed to use the drug or undergo particular treatment as it can harm the patient; at times, it can be dangerous and life threatening as well. When a procedure should not be combined with other procedure or when a medicine cannot be taken with another medicine, it is called Relative contraindication. Contraindications should be taken seriously as they are based on the relative clinical experience of health care providers or from proven research findings.
