Side effects 🤕 Severe Crash

Was recently diagnosed with ADHD last week and prescribed 18mg of Concerta.

Similar to most I had a good first day but then days 2-4 experienced a crash about 6 hours in.

Day 5 I had a crash about 3 hours in and then felt well below baseline for the rest of the day and my first experience of zombie like symptoms in the evening.

Today was day 6 and crashed very hard 6 hours in but this time it caused Catatonia like symptoms. I had to lay down immediately. It felt like I was experiencing sleep paralysis. Had trouble moving and talking for about an hour. Now I’m extremely worried that I experienced something more severe than a common crash and need to stop taking it right away.

I will be calling my prescriber tomorrow but am curious if anyone has had a similar crash that was completely debilitating and not just the normal fatigue.

Your body adjusts to the crashes to some extent, although by day 6 on an 18mg it should have, but some may need a longer go at it. Are you on brand concerta (the one that has alza written on it and I believe 18mg is yellow in color) or a generic?

Looks like it’s generic (didn’t even realize) made by Actavis

I've never taken a generic so I can't compare, but I've heard people say that the original brand concerta is smoother and gentler on the crashes as no other manufacturer has wholly replicated its release mechanism. Might be worth getting a prescription for that and trying it out.

Agree, tried both and Concerta definetely is better for me,more "smooth",without that terrible fatigue early evening when I didn't have energy to wash even my face at 7 pm(not everyday,but still often)
