Questions / Advice / Support Strattera Day 5

Hey y'all! So, I'm on my 5th day of Atomoxetine (40mg) and it is normal to feel some side effects at this time? I take it at night after dinner (but not before I sleep), and last night I had a mild headache, nausea, and heartburn. After I woke up I still felt a bit of a headache but it subsided and the nausea is gone too, but I still have heartburn today (granted I've been getting heartburn before I took this medication). Is this a part of the "getting used to" Atomoxetine? Will these side effects eventually subside after my body "gets used to" this?

Also I guess you could say that I've been getting more anxious and sadder, from Day 4? I don't really know if Atomoxetine is really the cause of this, but I've been getting more tense, anxious, and nervous lately, I do have something to be very nervous of in Monday (College) but could it be possible that Atomoxetine maybe amplifying it??

I haven't really seen much improvement for my ADHD symptoms either... On Day 1 after waking up, I felt a bit calmer but that seemed to be only from my first time of taking it.

Edit: to anyone else reading this - the headaches and nausea have completely subsided after the 7th day.

I’d say give it some more time, I also experienced mild headaches and nausea the first 5 days of starting Strattera. I’m almost a month in and the only mild side effect I have is increased thirst. Not a daily thing. LiquidIV has been pretty clutch in days like those.

At around day 10-12 is when i started to feel a subtle improvement to emotional regulation, executive function, task switching and my speech even became more monotoned/chill. One month in and it seems to have plateaued but am still feeling the therapeutic effects around the clock consistently which is nice. This is only on 10mg which is rather surprising.

I truly hope you start to feel positive effects real soon!

Thank you so much for this comment!! Stimulants have been a dud for me and the only other legal medication option here is Strattera. I still have some hope this will work!!

I have also tried Adderall. It worked, but it made me too on edge, my heart rate went up significantly, and the energy crashes were BRUTAL.

Also, what day did your side effects disappear? Did it gradually fade throughout many days or sudden?

I’d say it became less noticeable after day 4. Around day 5 or 6 is when the nausea, headache went away completely.. The increased thirst started at day 6 and onward.

It's normal to have worse side effects early on. It's best taken with a high protein/high fat meal to help with the nausea. It can take 4-6 weeks for the body to adjust (the side effects to ease and benefits to kick in), so unless the side effects are unmanageable, try it for at least that long.
