ADHD medication may not work. Then what?

ADHD medication works well for most adults, but some people just don’t respond to it. There are other ways to manage your ADHD symptoms if meds aren’t effective.

Medication is the main ADHD treatment for adults. There are two types of ADHD drugs that professionals prescribe. The most popular type is stimulant medication. The other group is non-stimulant drugs.

Stimulants are divided into two classes of medicine. Methylphenidates include drugs like Ritalin, Concerta, and Focalin. Amphetamine/dextroamphetamines include Adderall and Vyvanse. The non-stimulant group includes Strattera (approved for adults), Qelbree (approved for kids), Catapres, and Kapvay. 

ADHD drugs target two brain chemicals that affect attention and mood. These key chemicals are dopamine and norepinephrine. The ADHD brain has trouble accessing them.

Stimulant medications are considered the first-line ADHD treatment for adults. They work in about 70 percent of adults with ADHD.1

But what if you’re in the other 30 percent?

Your prescriber might try non-stimulants. These drugs work differently in the brain. But they have an even lower response rate than stimulants do. So, many people with ADHD have to go without the benefits of any ADHD medication.

If you’re one of them, you may feel frustrated, discouraged, or alone in your struggles. It’s important to remember that your situation is fairly common. And there are other steps you can take that may provide some relief, like therapy and certain lifestyle changes. 

Sometimes ADHD medication helps, but only a little. Or it may be effective for a while and then stop working. 

If your meds aren’t improving symptoms like focus and attention problems, it doesn’t necessarily mean you don’t respond to medication. Your prescriber may need to adjust the dosage or switch to a different class of drugs. It can take a while to find the right medication and the right dose for a person’s biochemistry. 

If you also have mental health or medical conditions, they may be making ADHD symptoms worse. To feel better, you’ll likely need to treat both your ADHD and any other health problem. Make sure your prescriber knows about your medical history or any medical concerns.

Before you give up on ADHD medication, talk to your prescriber and ask what changes might help.

Experts don’t know why some people respond to ADHD medications and others don’t. But they point to a few possible factors.

Body chemistry affects the way ADHD medications work. The only way to know how you will or won’t respond is through trial and error. Prescribers may need to try different drugs or dosages to find the right plan. But for some people, no medication or dosage is effective.

“Everybody’s biochemistry is going to be different,” says neuropsychologist and Understood Expert Karen Wilson, PhD. “Some people simply don’t metabolize stimulants well or don’t experience the expected benefits. If a family member with ADHD responds well to a certain medication, there’s a higher chance you will too, but that’s not always the case.”

Let your prescriber know if you have a family history of ADHD. Also share which medications family members take.

Some people don’t respond to ADHD drugs because they’ve been misdiagnosed with ADHD. Other conditions — like anxiety and mood disorders — can look like ADHD. Many conditions can also co-occur along with ADHD. It takes an in-depth evaluation to know what’s behind the symptoms.

“If you were diagnosed in a brief 15-minute telehealth appointment, there’s a chance that another condition is at play,” says Wilson. “A comprehensive evaluation that includes a childhood history, academic records, and input from family members can help confirm whether ADHD is the correct diagnosis.”

If you have another health condition that causes similar symptoms to ADHD, you may think your meds aren’t working when it’s another condition at play. Let’s say you’re taking ADHD medication, but you’re still having trouble focusing on tasks. You might assume the drugs don’t work for you. 

But if you also have depression, that condition might be causing the symptoms. ADHD drugs wouldn’t address that.

Up to 80 percent of adults with ADHD also have at least one mental health condition.2 These may include:

ADHD also often co-occurs with autism, sleep disorders, and some learning disabilities. If you have other conditions as well as ADHD, you need to treat each one separately. “If you’re treating depression with ADHD meds thinking it’s ADHD, then you’re not going to get the benefit,” says Wilson. 

It can be upsetting if medication doesn’t help you when it helps so many others. It’s true that nothing can replace ADHD drugs when it comes to symptom relief. But there are some strategies and treatment options you can try that may improve the quality of daily life.

Different types of therapy can often help with emotional issues that may happen with ADHD. Cognitive behavioral therapy (CBT) is a type of talk therapy. It gets people to think about their thoughts, feelings, and behavior. 

CBT can help lower both ADHD symptoms and strong emotions. When ADHD symptoms decrease, depression and anxiety also often get better.3 

Having more control over your emotions may reduce some symptoms of ADHD or help you manage them better, according to clinical psychologist Lara Honos-Webb, PhD. “Emotional regulation is like having the best version of yourself be in charge of your words and actions,” she says. 

Dialectical behavior therapy (DBT) also helps people learn to regulate their emotions. It’s a form of CBT, but is a very structured program. DBT focuses on recognizing and accepting how you’re feeling in the moment.

Maybe you focus better when it’s totally quiet. Or maybe listening to music helps you stay on task. Adjust your environment to meet your needs. That might include using noise-canceling headphones, placing baskets around your home to hold and hide clutter, or creating a space to go to calm down when you’re feeling overwhelmed.

Research shows that physical exercise and activity can reduce ADHD symptoms and improve executive function. (The research looked at aerobic exercise in particular, like biking and running).

Exercise can also improve mood and self-confidence. It increases the accessibility of brain chemicals that the ADHD brain doesn’t get enough of. These include dopamine and norepinephrine.4 

Mindfulness is a form of meditation that can improve attention.5 It can also reduce anxiety and depression, which are common with ADHD. Mindfulness techniques help direct your attention to the present. They also help you to tune out distractions. 

One technique to try is called walking meditation. Find a quiet area that’s 10 to 12 feet long. Slowly walk from one end to another, focusing your awareness on the experience of walking — keeping your balance, the sensation of standing, the movement of your hands and feet. When you reach the end, turn around and keep going.

Sleep problems are very common with ADHD and make symptoms like inattention and trouble with working memory worse. 

Getting the recommended seven to nine hours of sleep6 every night is a challenge with ADHD. The brain has a hard time winding down. ADHD can affect sleep patterns and interrupt your sleep. And bedtime procrastination is common.

To improve your sleep, avoid caffeine later in the day. Have a regular “unwind time” before bed for calming activities like reading or taking a bath. And turn off all screens — start at 15 minutes before bed and build your way up to 30. Changing this habit may be especially difficult and take some time.

Stimulant medication is the most common treatment for ADHD, and it works for 70 percent of adults. But if you’re one of the 30 percent it doesn’t work for, you may wonder why — and what else you can do to relieve ADHD symptoms. 

Your prescriber might try you on non-stimulants. These drugs work differently in the brain. But they have an even lower response rate than stimulants do. Many people with ADHD have to go without the benefits of any ADHD medication.

Experts don’t know why some people don’t respond to ADHD medications, but they point to possible factors. Everybody’s biochemistry is different. Some people don’t metabolize ADHD drugs well and don’t get the benefits from it. 

Also, the medication won’t work if you don’t actually have ADHD. There’s a lot of overlap between ADHD and other conditions. These include mood disorders and anxiety. Some people may get the wrong diagnosis.

If ADHD medication doesn’t work for you, there are things you can do to make symptoms more manageable. These include cognitive behavioral therapy, getting enough sleep, exercise, and practicing mindfulness.
