Can phentermine be used to treat ADHD?

This is a valid question because phentermine is a stimulant. It is often prescribed for weight loss but is there any evidence out there on phentermine and ADHD?

Attention Deficit Hyperactivity Disorder is a condition that affects millions of people in the United States. Especially in children.

The estimated number of children ever diagnosed with ADHD, according to a national 2016 parent survey is 6.1 million (9.4%). This number includes 388,000 children aged 2–5 years. 2.4 million children aged 6–11 years. (source).

Symptoms can include difficulty paying attention, hyperactivity, and impulsiveness.

While there are many treatments available for ADHD, phentermine may be a viable option for some people.

In this blog post, we will discuss phentermine and its potential use as a treatment for ADHD.

Phentermine for ADHD – Can phentermine be used for ADHD?

Phentermine is not approved by the FDA for the treatment of ADHD. However, it is sometimes prescribed “off-label” for this purpose – due to its similarity to amphetamines, which are approved for the treatment of ADHD.

Phentermine is a stimulant that functions much like Adderall and Ritalin – the two most common medications prescribed for ADHD.

As we all know, phentermine is a powerful medication. And can also stimulate the production of dopamine, which results in increased motivation, memory, and attentiveness.

So can phentermine be used to treat ADHD? The answer is yes, phentermine may be a viable treatment option for some people with ADHD. However, more research is needed to determine if phentermine is an effective treatment for this condition.

What is Phentermine and how does it work?

Phentermine (also known as Adipex-P) was first introduced in 1959 as an appetite suppressant. It is a phenethylamine and amphetamine derivative.

Phentermine works by increasing the release of norepinephrine, which is a neurotransmitter that helps to control attention and focus.

It also blocks dopamine receptors in the brain, which can help to reduce hunger cravings.

Phentermine affects several different neurotransmitters in the brain connected to appetite control.

From my research, I also discovered that phentermine can increase the release of dopamine. Dopamine is a neurotransmitter that is associated with pleasure and motivation.

For instance, have you ever seen yourself in the mirror and thought to yourself, “Wow, I look good today!” And then felt motivated to keep looking your best? That’s dopamine working.

Or a scenario where you participate in a competition and you really want to win. The dopamine is firing and giving you the extra push that you need to do your best.

So phentermine not only suppresses appetite by increasing norepinephrine, but it can also increase dopamine – which can improve attentiveness and focus.

There’s a gland in your brain called the hypothalamus. The hypothalamus controls things like hunger, thirst, sex drive, body temperature, and how active you are. It also helps to control the production of some hormones.

This drug is particularly administered to those looking to lose weight and has been clinically studied to show a modest weight loss.

And that’s what I’d recommend it for!

Although over the years, it has been labeled as a schedule IV controlled substance, meaning you can only get it legally with a prescription, it is not without side effects. More on the effects later.

For this reason, it should be taken exactly as prescribed by your doctor and never shared with others. It’s also important to note that phentermine is only meant to be used for a short period.

If you’re into fitness, bodybuilding, or an athlete – this could be challenging: following a strict prescription and all that.

This is why I’d recommend you check out PhenQ. An all-natural, safer, legal alternative.

Then for ADHD patients – below are some ways that are helpful.
