1,3-dmaa and Pemoline

Here is the interaction we found between these two, with the evidence behind it.

Moderate

STIMULANT DRUGS

Why this applies to Pemoline

Pemoline falls under STIMULANT DRUGS — the group 1,3-dmaa interacts with.

1,3-DMAA is thought to have stimulant effects. There is concern that taking 1,3-DMAA with stimulant drugs might increase the risk of adverse cardiovascular effects. Some preliminary research shows that taking 1,3-DMAA 50 mg daily in combination with caffeine 250 mg daily does not increase respiratory rate, blood pressure, or other cardiovascular outcomes compared to taking caffeine alone in healthy men. However, a number of cardiovascular side effects have been reported for patients taking 1,3-DMAA in combination with other stimulants including caffeine. Theoretically, combining 1,3-DMAA with stimulant drugs might increase the risk of adverse cardiovascular effects. Some stimulant drugs include amphetamine, caffeine, diethylpropion (Tenuate), methylphenidate, phentermine (Ionamin), pseudoephedrine (Sudafed, others), and many others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: Pemoline (Cylert) is a stimulant used for attention problems, and it gently revs up your nervous system. DMAA is also a powerful stimulant that pushes your heart rate and blood pressure up. So when you stack two stimulants together, you're not just adding their effects, you may be amplifying the strain on your heart and blood vessels.

With both on board, you could see a racing or pounding heart, higher blood pressure, jitteriness, trouble sleeping, or chest discomfort. To be honest, this concern is based mostly on how these drugs work rather than solid human studies, so it's theoretical. But DMAA itself has been linked to serious heart events and is banned in supplements, so I'd steer clear of it entirely. Please check with your doctor or pharmacist before combining anything like this.
