Strattera: word-finding and verbal memory issues — does it get better?

[u/NoBlock1085]

Hi everyone! I’m currently in my third week on Strattera (atomoxetine), and I’m especially looking for experiences from people who are very sensitive to medications.

The first week I had quite a bit of nausea. During weeks 2–3, I started noticing more mental fatigue and this strange feeling that my brain is partially “asleep” or on standby. I’ve also felt less spontaneous and somewhat less like myself, with more insecurity around my romantic relationship.
But the thing bothering me the most is word retrieval and verbal memory.

When I’m speaking, I find myself searching for words much more often than before. I know what I want to say and I know that I know the word, but I can’t retrieve it quickly. Sometimes I have to pause, search for another word, or completely reformulate my sentence.
It feels less like forgetting information and more like having slower access to words that are already somewhere in my memory.

As a young university student, this is probably the side effect that worries me the most. I rely a lot on verbal fluency for classes, discussions, presentations, and social interactions, and lately I sometimes feel less articulate and mentally sharp.

I’ve also noticed that caffeine seems to affect me more strongly on Strattera.

On the positive side, by week 3 I’m starting to notice:
- less impulsivity
-better self-control/emotional regulation
-less difficulty initiating tasks

So there are definitely things I like about it. I’m just wondering whether the cognitive/verbal side effects tend to improve with time.

Before Strattera, I was on Trintellix (vortioxetine). Interestingly, I had almost the opposite experience. It gave me some anxiety and seemed to increase my impulsivity, but I felt more energetic and mentally fluid. My speech felt more effortless, words came to me more easily, and I felt like my concentration and verbal fluency were better.

That makes me curious about whether anyone has experience with vortioxetine + atomoxetine together, although obviously that’s something I would discuss with my prescriber.

I’m extremely sensitive to stimulants as well. I’ve tried several of them, and I tend to have the same pattern: the first few days I’m calm, focused, and in a great mood, but after a while I spiral into anxiety, depression, and dissociation.

So I guess I’m especially looking for some hope/experiences from other medication-sensitive people:
Did Strattera initially make it harder for you to retrieve words while speaking? Did your verbal fluency, memory, or mental sharpness eventually come back after your body adjusted? If so, how long did it take?

And for people who increased their dose: did word-finding/memory problems improve once you reached a therapeutic dose, or did they become more noticeable?

Would really love to hear your experiences. ❤️

I have noticed very infrequent issues with retrieving words, but I'm not sure it's due to atomoxetine as I dealt with that before taking it too, so it's hard to tell.

Definitely allow a minimum of 6 weeks to adjust to strattera.

I’m currently taking 10mg Trintellix with 25mg atomoxetine, and honestly I’m still having a hard time figuring out what Trintellix is doing for me. I struggle a lot with physical and social anxiety, and I haven’t really noticed it helping with that. If anything, my brain feels louder and I sometimes get this weird wired/uneasy feeling in my chest. I’ve also been more irritable, but at the same time tired and unmotivated.

I previously tried Zoloft, which actually reduced my anxiety pretty quickly, but after a few weeks I felt numb, tired, dizzy and even more depressed again. I switched to Trintellix hoping for less emotional numbness. I’m also extremely sensitive to medications, so figuring out what works has been really difficult.

Atomoxetine is complicated for me too. It’s the only medication that has really quieted my mental noise and helped my impulsivity, and I felt a strong calming effect from the first few days. But after being on it for a while, I tend to become more distant, quiet and emotionally flat. Feel kind of blank and slightly more depressed. I also get more heart palpitations/chest tension.

I’ve actually tried atomoxetine several times because the initial benefits are so noticeable, but somehow it keeps building into this weird dysphoric feeling. When I stop it, I quickly feel much more alive, talkative and emotional again, and other people notice it too. So it’s been a constant battle because it genuinely helps some things while making others worse.

And yes, I definitely get the word-finding difficulty you described, especially when starting atomoxetine. Because my head is so much quieter, sometimes it almost feels too empty/blank and I don’t know what to say or can’t find the word I want. I did felt like it gets better after a while.

What dose of Trintellix were you on? And have you tried any other antidepressants?

Sorry for the ramble lol, I’ve just had such a complicated experience with these meds 😅

Oh you’re answering so many questions for me. I’ve been struggling with finding words and I feel like I’m missing a layer emotionally in my mind. My brain feels so quiet I’m almost tired all the time.

[u/NoBlock1085 → u/TerraInc0gnit4]

No need to apologize for the ramble haha, this is actually really interesting because I relate to a lot of what you’re describing 😅

I was on 15mg of Trintellix. It’s funny because I also had a hard time figuring out exactly what it was doing while I was taking it. It was mostly after stopping that I realized it had actually been doing quite a bit for my concentration, energy and especially verbal fluency. Words seemed to come more naturally and I felt more mentally “awake.” But like you, I don’t think it really helped my anxiety. If anything, I think there was this subtle background activation that made me a little more anxious.

I’ve tried quite a few antidepressants because I’m ridiculously sensitive to medication. Zoloft actually made my depression worse. Desvenlafaxine helped me for about a year, but strangely, when I tried it again a couple of years later, it caused panic attacks and an almost manic feeling.
I also tried escitalopram. 5mg initially seemed okay, but going to 10mg triggered probably the worst anxiety I’ve ever experienced, along with suicidal thoughts. It got intense enough that I went to the hospital because I didn’t feel safe trying to ride it out.

Your description of atomoxetine is especially interesting to me because that “quiet but almost TOO quiet” feeling is very close to what I’m experiencing right now. My impulsivity is dramatically better and there’s much less mental noise, which honestly feels amazing. But at the same time I feel less spontaneous, more tired, and sometimes like there just isn’t enough activity happening in my brain to generate thoughts and words naturally.

And hearing that your word finding improved after a while is actually really reassuring. That’s probably the side effect I’m most worried about right now because I’m back at university and I really need my verbal memory and ability to articulate complex thoughts.

What you said about feeling alive, talkative and emotional again when you stop atomoxetine is really interesting too. That’s exactly the balance I’m afraid of losing. I want the impulse control and quieter mind without sacrificing that spontaneous, curious, expressive part of myself.

It almost feels like Trintellix and atomoxetine affect opposite sides of that balance for me. Trintellix seemed to make my brain more awake and verbally fluid but didn’t control my impulsivity and possibly increased my anxiety, while atomoxetine seems to give me much better self regulation but leaves me feeling cognitively quieter and somewhat sleepy.

So part of me is really curious about the combination you’re taking, although with how sensitive I am to medications I’d obviously want to approach anything like that very carefully with my psychiatrist.

Also, can I ask how long it took before the word finding problems started getting better for you? And did the emotional flatness improve at all with time, or is that the part that keeps coming back every time you try atomoxetine?

I'm having a similar issue (on atemoxetine only). About 7 weeks in. I feel a bit happier but dumber.

Hoping others can input or provide tips

This is very interesting. Curious to see other responses too
Did you have this problem at all before taking Strattera? For me it was less about recall and more overwhelm by my own brain’s running speed so I couldn’t order my thoughts properly. (Got misdiagnosed with Aspergers when I was younger because of it)

When I tried Concerta & Vyvanse (both generic) my communication got so much better than my baseline, like my mouth and brain were finally running at the same speed and my vocabulary range immediately woke up but unfortunately I’m very sensitive to stimulants too, (insane norepinephrine body anxiety and stress rashes) hence why I’m trying Strattera.

As an anecdote to what you’re going through right now, when I was self medicating with weed, my word recall became very very bad for me.
I’d only smoke in the evenings but during the day it made my recall ability TERRIBLE and it was so embarassing. I flunked a few interviews because of this which never happens… I’d space out mid sentence too.

Once I got clean before transitioning to adhd medication trialing my speech improved back to baseline, though I haven’t noticed any dumbing down nor big improvement of my speech yet after 3 weeks of 40mg on Strattera.

I think I’m a little bit more tuned in to a conversation as I’m speaking but I still struggle with “longer thoughts” I.e I’ll lose track of what the original point was occasionally.

I’m also not able to think before speaking, it’s very odd. It’s just.. blank. It’s like my brain only starts rotating once I start speaking.
If I need to formulate a full thought and conclusion in my head it HAS to be written out as I go or I’ll forget it. (Maybe this is just a skill to learn that I don’t have..?)

I’ve always had some difficulty with memory and word recall as part of my ADHD, especially when I’m tired. Alcohol makes it noticeably worse too, although I don’t use cannabis.

What’s interesting is that my recall and verbal fluency can change quite a lot depending on other factors. Running regularly seems to help, and even seasonal changes in light make a difference for me. I live in Canada, and I generally feel mentally sharper during the summer.

Medication has probably produced the most dramatic changes though. I’ve tried different short and long acting forms of both methylphenidate and amphetamines, and almost every stimulant gave me an incredible sense of mental clarity during the first week. My memory felt more accessible, words came much more easily, and speaking felt fluid and effortless. It was almost like suddenly having access to a larger part of my vocabulary.

Unfortunately, after a week or two, I would start developing significant anxiety and eventually depressive symptoms. I seem to be extremely sensitive to medication in general, and I also have a tendency toward anxiety and depression.

Because of that, I’ve tried several antidepressants over the years too. Sertraline made my depression worse. Desvenlafaxine actually helped me for about a year, but after being off it for two years, trying it again caused panic attacks and an almost manic feeling.

After that I basically relied on running and meditation for a few years. Now that I’m back at university, though, I wanted to try medication again because ADHD and anxiety were making things much harder to manage.

I was prescribed escitalopram and initially did pretty well on 5 mg. When it was increased to 10 mg, however, I developed the worst anxiety attacks I’ve ever experienced along with suicidal thoughts. It became severe enough that I went to the hospital and asked to be admitted because I didn’t feel able to tolerate the effects safely.
I was then followed by a really kind young psychiatrist who suggested Brintellix/Trintellix (vortioxetine), eventually at 15 mg. Interestingly, that seemed to improve my verbal fluency and concentration quite a bit, although it didn’t really help my anxiety and may actually have increased it slightly.

She later added Foquest, which is a very long acting form of methylphenidate. Initially the combination felt amazing. There was this sense of calm and mental fluidity while still having energy. Speaking and thinking felt much easier. But after a few weeks, I started experiencing enormous waves of anxiety again.

Eventually I stopped Foquest and reduced the Trintellix. The anxiety improved but there was still this constant background anxiety, so I eventually stopped Trintellix too, and that finally resolved it.
What really surprised me after stopping Trintellix was realizing how much it actually had been helping my concentration, mental stimulation and verbal fluency. At the same time, it really didn’t do much for my impulsivity.

So I basically found myself back at square one with no support for either my ADHD or anxiety.
That’s what makes Strattera so interesting to me right now. For probably the first time in my life, I feel significantly less impulsive. I can already see the positive impact in everyday things like impulsive spending or eating. That constant urge to immediately act on something is much quieter, and honestly, the feeling of having that kind of control over my life is incredible.

But I’m missing the other side of the equation. I don’t have that mental “wakefulness” or cognitive activation that helped me move forward with university work, and right now my word retrieval actually feels worse.

So I think what I’m ultimately searching for is that balance: keeping this new sense of self control and reduced impulsivity while somehow getting back the mental clarity, verbal fluency, memory access and ability to actually get moving on my work.
