When you hear the word “Amphetamine,” you might immediately think of illegal drugs. However, did you know that when prescribed correctly by a physician, these are highly valuable medications used to treat various conditions, including attention deficit disorders (ADHD)? Let’s clear up the fear and confusion to understand what they actually are, how they work, and what you need to keep in mind when using them.
What exactly are Amphetamines?
Simply put, amphetamines are a class of stimulant medications that affect your central nervous system, which includes your brain and spinal cord. They help your body become more alert and active.
Think of your brain as having tiny messengers that carry information back and forth. We call these neurotransmitters (Neurotransmitters). These medications work by increasing the release of messengers like Dopamine and Norepinephrine (Norepinephrine) and ensuring they stay active in your system for longer.
As a result, you may experience the following:
- Increased alertness and attention.
- Improved focus on tasks.
- A feeling of energy and vitality.
- Decreased appetite.
- A sense of improved mood.
The most important thing is to take these medications exactly as prescribed by your doctor. Misusing them—such as taking higher doses than recommended or using them via routes like smoking or injection—can trigger a “high,” which may lead to abuse and addiction. However, when used exactly as directed by your physician, the risk of addiction is significantly reduced.
What conditions are these medications used for?
There are several types of amphetamines available under various brand names. They are used to treat a range of medical conditions.
| Type of Amphetamine | Conditions Treated |
|---|---|
| Amphetamine and amphetamine mixtures (e.g., Adderall®) | Attention Deficit Hyperactivity Disorder (ADHD), Narcolepsy, Obesity |
| Dextroamphetamine | ADHD, Narcolepsy, Obesity |
| Lisdexamfetamine (e.g., Vyvanse®) | ADHD, Binge-eating disorder |
| Methamphetamine | ADHD (used very rarely) |
| Phentermine | Obesity (short-term use) |
Other Medical Uses
Beyond these primary uses, some amphetamines are used in other ways. For example:
- Hydroxyamphetamine: Contained in eye drops used by eye care professionals to dilate your pupils before an examination of the retina.
- Levmetamfetamine: Included in certain over-the-counter nasal sprays used to relieve nasal congestion.
The Difference Between Amphetamine and Methamphetamine (“Ice”)
When many people hear the name Methamphetamine, they think of the illegal drug “Ice.” While they share a similar chemical structure, there are major differences.
- Potency: Methamphetamine is significantly more potent than Amphetamine.
- Speed of Action: The effects of Methamphetamine occur more rapidly than those of standard Amphetamine.
- Medical Prescription: Due to higher side effects and addiction potential, doctors prescribe Methamphetamine very rarely, typically only when other treatments for ADHD have failed.
Side Effects
Like any medication, amphetamines can cause side effects. While most are mild, there are some you should be mindful of.
| Potential Side Effects of Amphetamine Use | |
|---|---|
| Headaches, dizziness | Insomnia or sleep disturbances |
| Reduced appetite (potential weight loss) | Increased heart rate or elevated blood pressure |
| Restlessness, irritability | Nausea, vomiting, stomach cramps |
| Reduced blood flow to extremities (cold/discolored fingers or toes – Raynaud’s phenomenon) | Vision changes (blurred vision) |
| Severe allergic reactions (Anaphylaxis) – difficulty breathing, facial swelling | Chest pain (angina), abnormal heart rhythm (palpitations) |
| Mental confusion, hallucinations (Psychosis) | Serotonin syndrome – excessive sweating, confusion, tremors |
| Unexplained sores on fingers | Teeth grinding (bruxism), compulsive skin picking (dermatillomania) |
If you experience any of these severe side effects, notify your doctor immediately. In case of emergency, such as difficulty breathing, please go to the nearest hospital Emergency Room (ER) or call 911.
Can interactions with other medications and alcohol occur?
Yes, absolutely. Amphetamines can interact with many other substances. Please be particularly cautious with:
- MAOI antidepressants
- Blood pressure medications
- Antacids
- Insulin and other diabetes medications
- Other medications that increase serotonin levels
For this reason, it is vital that you inform your doctor about any other medications, vitamins, or herbal supplements you are taking.
Furthermore, please avoid consuming alcohol while on amphetamine treatment, as combining them can lead to unpredictable and dangerous health risks.
Managing the “Crash”
Some individuals experience a sudden onset of fatigue, irritability, restlessness, and difficulty focusing as the medication wears off—often referred to as a “crash.” While this is a known effect, if it significantly disrupts your daily life, speak with your doctor. They may be able to adjust your dosage or switch you to an extended-release formulation for a smoother experience.
