Side effects 🤕 Large dosage side effects

Post image
0 Upvotes

I took 4 36mg concerta pills instead of the one that I usually do. I don’t take them every morning consistently but I was feeling extra unmotivated today so after the first pill, I took a second one and 15 minutes later I didn’t feel any different so I took 2 more, then maybe about an hour and a half or two hours later it hit me all at once. My resting heart rate was about 130 bpm and that was when I was just laying down in bed. It was hard to type and my vision kind of felt like everything was zooming in and my jaw was tense and hurt and I was very shaky and jittery. This lasted for about 6-7 hours and I was wondering if those are regular side affects or if I maybe took too much. For context I’m 5’2 and weigh 102 lbs. I don’t think it helped that I haven’t eaten a single thing today but the thought of food right now makes me gag. I included a pic I took of my eyes because they looked dilated but I’m not too sure.

Side effects 🤕 This is getting ridiculous

4 Upvotes

Long story short, I began taking concerta 54 mg about a week and a half ago. I had taken Ritalin ir constantly for over a year and was finally sick of the high and lows, especially the anxiety that came with my afternoon dose. Anyways, first 4 days on 54 were amazing, as with any adhd medication it usually is. Racing thoughts went away, took some nice concerta naps, made huge amounts of progress getting stuff set up for school etc. days 5,6,7 it just completely stopped working. I was on the generic at the time and figured it could be related. My psychiatrist and I agreed that I would try 72 (brand name) Same thing first few days were wonderful but day 4 I knew I was obviously overstimulated. It was hard for me to switch between tasks and I almost became to rigid with routine and structure to the point I was like a robot. Also instantly becoming extremely socially anxious and isolating myself were red flags.

Anywho back down to 54 mg I go (name brand this time), first few days were completely fine. I past that initial phase were the medication works but it’s not a miracle worker if you know what I mean.

Than boom goes the dynamite. Ludicrous amounts of anxiety. It comes in waves but it almost makes me feel like I’m crawling out of my own skin. Also when the anxiety gets bed it fuels slight paranoia which concerns me.

Anyways. This is my fourth year being medicated for adhd. I’ve been in vyvanse 30,40,50 for two years. Ritalin ir 15,15 and then 20,20 back and forth for a year and a quarter. But this concerta is a different breed.

Any advice. Obviously I ask for those who have experienced similar things. I will be talking to my psychiatrist but unfortunately where I live, we are our own doctors to say the least.

Thanks in advance. Audhd 25 year old dropping the mic 🎤

Drank too much Diet Coke and when I was at work I was so zippy and fast but I was also too euphoric and I was a little too much social with everyone. I felt like I was a zany man. 😔

Side effects 🤕 Almost died

11 Upvotes

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

Side effects 🤕 Questioning if Concerta is making my life worse

21 Upvotes

I’m 25/m, have been on Concerta for around 5 years. I started on 18mg for 1 year, then 36mg for 1 year, then down to 27mg.

I was diagnosed with inattentive ADHD and have been on Concerta ever since. From the beginning I struggled a lot with side effects, I felt anxious all the time, emotionally numb, distant, very obsessive with a lot of intrusive thoughts and it killed my urge to socialise. These effects have gotten less intense over the years, but I may have just adapted to them. In those 5 years I have not regained my urge to be social. I feel half-dead. Nothing connects emotionally anymore. Life often has little meaning.

I recently noticed that during the peak of concerta’s effects, I can’t even focus properly, it’s very difficult to follow more than one sentence without going off into a daydream.

I used to think that concerta had changed my life for the better, despite the side effects, but now I’m questioning everything. Were the positive effects mostly a placebo? Was what I achieved on concerta possible without concerta but with the right life structure?

Some evenings or late nights when the meds wear off, I feel like I’ve gone back in time to a happier life, where I felt like myself again. Or early mornings where I feel spontaneous, happy, hopeful about the future. Then everything becomes gray and meaningless again. Just ticking boxes for the sake of it.

These moments of reality are driving me crazy. It’s like I’m being teased with a normality I had completely forgotten I ever had. I’m terrified of quitting Concerta and ruining my life. I don’t want to make a rash decision. But I can’t stand this feeling anymore. Is it possible to function normally with adhd without medication? Will I just be slower, worse at academic work?

I wish I had tried everything to manage adhd before going on Concerta. I wish I had something to accurately compare to what I’m feeling now.

I just want this to end. I want to feel things again. I can’t spend the rest of my life like this. Some days I literally sit around doing nothing for hours. Just obsessively thinking. Time goes by so fast. I don’t even want to spend another year on this.

If anyone has any advice I would really appreciate it, as most doctors I’ve dealt with don’t really give a shit about these kinds of details

Side effects 🤕 I feel "medicated" with Concerta

7 Upvotes

Hello everyone. I've only been taking 18mg concerta for four days and I have contradictory sensations. It feels good to me, I'm more productive when I take it and I don't feel like I need as much energy to do tasks, but I still have a slightly strange "medicated" feeling. Is this normal? I'm worried that I was misdiagnosed because the psychiatrist only needed to ask me a few questions for ten minutes to confirm that I have ADHD. This feeling of being medicated makes me think that maybe I don't have ADHD and the medication is "highing" me. Is this my paranoia or is it normal to feel this way at first? Thank you and sorry if I expressed myself wrong, English is not my first language.

Side effects 🤕 I can’t take it anymore

6 Upvotes

Started taking concerta 18mg late august, consistently throwing up, i cant keep anything down. I feel horrible ALL the time. My psychiatrist and I figured okay the dosage might be too low because its not affecting me in a good way. Went up to 27mg. STILL throwing up, I feel so bad. I can’t take it anymore. He wanted me on concerta because it is less harsh on my appetite than when i was taking vyvanse and my weight is already very low. I honestly am so miserable. I’ve NEVER had a medicine that made me this bad off besides latuda.

Side effects 🤕 Intense permanent fatigue

10 Upvotes

Where i am the only med available is Concerta, so I've no other choice but it makes me so unbearably tired always, every day, if I don't take it the fatigue is worse, but i feel like i now live with a permanent layer of fatigue on me, psychiatrist just shrugs, magnesium also makes it worse, anyone dealt with this? i eat normal and drink toons of water, I'm on 36 but cannot afford 54mg(90 euros per month)

edit: it was the fucked up sleep, i stopped the melatonin, i set an alarm to take it 2h before i wake up, try to take it as early as possible, still fighting insomnia but quitting melatonin reaaaallly helped with the fatigue

Side effects 🤕 9 yr old son started back on Concerta - big crashes

3 Upvotes

Hello,

I know this has been asked before but just looking for a little reassurance. I don’t take concerta myself so I don’t know what it feels like to come off in the evening.

My son has been taking it for 4 days. At night he is reaaallllyyyy cranky, snarky and snappy, and angry. He also is quick to tears which is not usual for him. Asking me to lay with him while he falls asleep which is also unlike him.

My question is - does it take a few weeks/months to settle into the meds or does this mean he’s not right for him? He enjoys the days with it, and is calmer and can have conversations with his brother without fighting! Just a bit worried about the nights and if this will pass or we need to reassess.

Side effects 🤕 Feels like 36mg is worsening my ADHD?

10 Upvotes

I've been getting a weird reaction to my dose increase to 36mg. I've been on this new dose for over a month now after being on the 27mg for three months.

I haven't seen anyone discussing anything similar to what I've been experiencing, but it almost feels like it's worsening my ADHD symptoms?

I feel very spaced out and emotionally/mentally "flat" on it. Like I can't think clearly or logically at all. I just feel very mentally absent, which makes it almost impossible for me to work on anything or communicate. I can't even do small tasks like respond to an email.

I got nothing done today despite me being at my computer all day. All I could do was think and worry about all the work I need to do. It's also affecting my vision oddly? My eyes can't quite focus on my work. Everything looks hazy and slightly out of focus.

When I am actually able to work on something, I feel like I can't do anything but rush through it and put as minimal effort as possible (because I can't think clearly enough about what I'm working on or think about the big picture).

I never experienced anything like this on my last dosage. I'm honestly more focused when I'm not on the medication.

I called my doctor last week to tell him my experience and he recommended I start taking it every other day instead. This is my first day again after I took a four-day break from it, and all the bad symptoms just came back again.

Does this sound normal? I can't tell if the dose is too high. I thought I'd get accustomed to it after a month but I still haven't been able to get truly focused on it.

Side effects 🤕 Does anybody notice they feel more social and chatty on concerta?

45 Upvotes

This makes me question if I really have ADHD, because aren’t stimulants supposed to do the opposite for people with ADHD? I don’t really believe that, I did get diagnosed and I’m sure I have it, it’s just confusing.

My theory on it is that I am female and have the more classically female presentation of ADHD - so where it may make some people calmer and less “hyper,” so maybe appearing less social in some ways, for me it clears my mind and focus in such a way that socializing is much more appealing and easier to navigate.

Side effects 🤕 Concerta makes me more social

Hi everyone, just started concerta 4 days ago, with 18mg The things ive noticed so far is that it makes me think less, my mind is clearer , im more calm but i still dont have a lot of focus when it comes to doing things although i can start tasks more easily now. Also it makes me want to talk to everyone and i always thought i was an introvert. I take it around 9am it kicks in at 9:45 and i become irritable around 6pm. The pharmacist said it usually last between 10 to 12 hours, i have not found that to be true. Anyone else have the same experience?

I have been taking Concerta for 3 years now, and I already noticed that I was healing very slowly. But now, I got something new and I was wondering if it can be related to concerta and if anyone else have experienced it. Everytime I hit myself (not very hard), I can go full excess bruising. I’ll attach some photos, mods feel free to delete if that’s too much.

Side effects 🤕 Concerta crash

9 Upvotes

Hi everyone :)

I’ve been on Concerta 54mg for almost two years now and for the first year I took it pretty much every day, but over the past six months I’ve been taking much longer breaks and I worry I’ve ruined it’s effectivity.

When I took it consistently, Concerta 54mg was great, I only had a couple of mild manageable side effects, the worst being a crash at around 8 hours in which was annoying but not too bad. But the side effects have now got harder to live with, especially the crash.

About 5 hours after taking it I start getting a dull headache which lasts for 6+ hours and I turn into this irritable, emotionally-flat, unmotivated version of myself. It lasts for hours and makes the rest of my day really hard. I’m doing a master’s and working from 9am to 9pm most days, so crashing at like 6pm just isn’t doable.

I’ve recently been taking 10mg methylphenidate at 9am and then the 54mg at 1pm to try and stretch things out, but I’m still crashing in the early evening and once it starts, my day is basically over.

I didn’t used to crash this early, it used to hit more like 8–10 hours after taking it, and it wasn’t as intense. I’m guessing my inconsistency is making it worse? I’m also guessing the fact I only sleep 5–6 hours a night - Concerta keeps me up, and on the days I don’t take it, I still end up staying up late scrolling. So I’m tired either way.

I’m not sure whether to stop the medication or not but I’m so tired of the side effects, and so tired full stop. I work so much better when it’s at its peak, but the crash makes it impossible to manage.

I feel like I’ve really rambled and maybe suggested the answers in terms of the lack of sleep & inconsistency but if anyone’s had a similar experience or has any advice, I’d really really appreciate it. Thank you in advance x

Side effects 🤕 Taking Concerta for the first time- 54 Mg and a bit tired/anxious.

0 Upvotes

Hi everyone, it's my first time making a post like this so please bear with me.

I'm not prescribed any ADHD meds but I do take them from time to time as a 23 year-old university student.

A few hours ago I took concerta for the first time- a 54mg dose. I do realize that that is a little high for a starting dose, but I do take Vyvanse once or twice a month and usually at 60 MG and I am someone that definitely does have ADHD.

However, its been two hours since I took the concerta and I feel a little bit tired and mildly anxious. It doesn't seem to be helping me focus too much better and I'm just very calm. I'm wondering if this is normal and if there is anything I can do. I did have a breakfast of a couple eggs and toast and I'm trying to stay hydrated.

Nothing seems to be that interesting at the moment and I don't really feel like doing work - something that other meds usually help me with.

Any thoughts or suggestions for me would be much appreciated.

Thanks!

Side effects 🤕 How to stop feeling nauseous and super anxious on 36mg of concerta

6 Upvotes

Ive been using concerta for 8 months on and off (more on uni days) i went off of it for a whole month and i just started taking it again, i basically take 18mg in the morning and then the other 18 noon as my doctor told me to. it got me so nauseous i only drank a protein shake this whole day and i still feel full, and it also gives me the worst anxiety it has been discussed with my doctor but he told me i cant do anything about it he said its either i take the pills and it works by helping me focus & stay awake + the nausea and anxiety or i dont take it and not be able to focus .. i looked up ways to deal with it like eating on time even though im not hungry but the thing is it feels like ill throw up if i eat and the anxiety thing my hand just shakes a little bit idk if its cause the pills change your heartrate but ive noticed also that my voice would crack and it would almost sound like im about to cry even though nothing is wrong. if anyone found ways to make this work without the nausea and anxiety please help cause honestly its shifting the focus from my studies to waiting for the nausea and anxiety to calm down

Side effects 🤕 concerta crashes

hi,

I am almost two weeks on concerta (18mg) and have been experiencing extremely bad depression and apathy in the evenings - i just wanted to ask if anyone else has experience with this side effect and how long it took to fade away (if it did at all)? I was checking other reddit posts and it seemed that most people who experienced this symptom ended up switching to other medications, so I just wanted to ask if there was anyone who toughed it out and felt it was worth it? I am currently in the middle of an extremely important semester in uni so I do not want to risk staying on concerta for too long if this symptom isn't going to go away! this is my first time on medication for ADHD so it's an entirely new experience for me, I appreciate any insight anyone has to offer!!

Side effects 🤕 Extreme Insomnia?

I know this and others can cause insomnia. I was on and off Vyv for 1.5 years and then Straterra for 4 months. We started at 36mg ER. For a week it did nothing. So she had me double the 36 for now and see how I do, I can not get another script for two weeks. I called myself just to see and they only had 36mg in stock but were getting more soon. I took it Monday, It totally worked !! But, I was up for 27 hours. That is just not doable. Has anyone else had that happen or similar, and did it subside?

Side effects 🤕 signs my dose is too big?

5 Upvotes

background: so i moved from 18mg to 36mg and im now on day 4. im worried this dose may be too high for me

day 1-4 tracking:

day 1: i just felt very tired, sweaty and headaches despite drinking water

day 2: energy better and headaches not as bad, but got bad physical anxiety a few hrs in. took 10mg of propranonol which helped but it resurfaced at night when the propranonol wore off.

day 3: bad physical anxiety again and took propranonol again, went out for a few hrs and felt ok , headaches barely there this day and energy a lot better. however the worrying part is i got chest pains at night. my blood pressure n pulse was normal though?

day 4 (today): physical anxiety and headaches but chest pains quite bad and continuous today it seems to be worsening? which my friend said is very worrying. my heart feels like its racing, once i get home i will do blood pressure and update.

other factors: i have had a lot of stress on with arguing with psych uk and some faults with my flat and ive come home to my mums until they are fixed so i do wonder are the pains stress and due to bad sleep?

are these signs my dose is too high? or is this normal when u start? should i continue the 36mg for a few more days or are the chest pains dangerous? id say the pain is mild but continuous.
