Does Adderall Use Cause Pupil Dilation?

Taking Adderall can cause pupil dilation, a state where the center of your eyes can be larger than their normal size. Dilated pupils, also known as mydriasis, due to Adderall use can cause increased sensitivity to bright light.

Adderall is a prescription drug that has dextroamphetamine as its main active ingredient. Adderall can be prescribed to treat attention deficit hyperactivity disorder (ADHD) in adolescents and adults. 

Eye problems can be an unintended side effect of taking Adderall.

If you’re experiencing eye-related problems due to Adderall use, over-the-counter (OTC) eye drops can help with your eye health. If problems persist, you may ask to see an eye doctor. Abusing Adderall to improve your focus or energy may increase your risk of eye problems.

How Adderall Causes Dilated Pupils

Adderall affects dopamine and norepinephrine neurotransmitters in your brain and sympathetic nervous system. These neurotransmitters affect your motivation, focus, and blood pressure, while also affecting the eye muscles in your retina.

Eye muscles normally contract and expand depending on the amount of light present. When you take Adderall, your eye muscles may expand at a higher frequency than normal, leading to pupil dilation.

Eye Problems Related To Adderall Use

Along with dilated pupils, Adderall use can cause eye-related side effects such as:

• blurry vision
• pinpoint pupils
• glaucoma

Adderall can also be linked to cases of acute angle closure glaucoma, a condition where the fluid pressure in your eyes rises quickly. Talk to your doctor if you are taking anticholinergic drugs such as atropine or antidepressant drugs, as concomitant use can increase your risk of this condition.

Studies show that high doses of dextroamphetamine, along with hallucinogens such as LSD and MDMA can cause pupil constriction, especially in cases of drug abuse.

How To Fix Pupil Size On Adderall

If you’re experiencing increased light sensitivity while taking Adderall, you may take an eye exam to determine the root cause. Your doctor may recommend over-the-counter and prescription treatment options to improve your eye health.

An optometrist may recommend contact lenses or sunglasses that can reduce the strain caused by bright light. If pupil dilation is due to illicit drug use, your healthcare professional may refer you to a prescription stimulant treatment program.
