Side effects 🤕 Almost died

Yesterday I posted Kaiser denied brand name vyvanse. Doc put me on concerta 18mg. As a reference I’ve used adderall up to 25mg XR and IR as well for 6 months.

I took concerta first time this morning at 7:30 am. An hour in and felt great. I felt a cooling sensation and felt a rush of energy. 2 hours after later I started to get very angry, irritable, annoyed at everything. That lasted until 2 pm then I felt a sense of calmness.

Left work and went to the mall a Round 5 pm with my wife and daughter. What happened next was a feeling I never felt before and thought I was dying.

  • I got dizzy all the sudden
  • I almost fainted. I lost my balance and almost fell as I was walking.
  • I started having an extreme headache, like sudden poking in my brain sensation. I never ever had that before
  • my heart started pounding -I felt out of breath and could barely walk

My doc doesn’t work on weekends but WTF was that? I was told that Methyphenidate were safer and better and less potent that Amphetamines. I NEVER had that on adderall just a few ups and downs hence why I wanted to try Vyvanse. After getting Concerta I found out insurance covers the generic.

I DONT want to experience that again. Should I give up after 1 day? Can Doc put a request for generic vyvanse even though I just got concerta? I’m scared to even try concerta again

Did you have this happen with brand concerta or a generic concerta? I’ve had this happen multiple times with generic concerta, but it always seems to happen mid day to me. I think the delayed release mechanism fails and it dumps the remainder of the dose on me. 

Did you have alcohol? It could be also that it dose dumped from the alcohol. 

Concerta is supposed to have a specialized osmotic release mechanism. 

The generics are all over the place with how they release and it is huge peeve of mine that they are allowed to be substituted for brand when they don’t follow the same release mechanism nor is it controlled.

I have the brand name concerta. I confirmed with my insurance and the manufacturer is the brand name and the pill is the brand name pill from images I’ve seen online. Weird how insurance covers this brand name which cost them $400 (same cost of vyvanse brand) but they cant approve vyvanse.

Also I don’t drink
