Can Extra-strength Tylenol cause hallucinations and vivid nightmares?

We've went through a lot of changes since July (2023),the last couple of weeks I've been having trouble sleeping, so I've been taking generic Tylenol Pm (blue tablets). I noticed I suddenly have been having nightmares, very vivid dreams, dreaming about being a teen,and about family that are no longer alive. I've talked in my sleep (off and on all my life) but it's been almost a year, yet, hubby told me I was talking. He said he couldn't understand because I was mumbling. I don't remember all of the dream,other than it being weird and two tv series kind of mixed together, neither have I watched in months.
I'm glad I found this because I thought I was going a tad loony.

I'm taking Tylenol for a broke rib and all of the sudden the worst vivid nightmares I can recall ever having. So detailed and so memorable when I wake up. Horrible. I think what as many people experience in this that they would evaluate what causes it in Tylenol. The regular 500 mg acetaminophen

This has happened to me. A year ago, I had my 3rd open heart surgery and will be on blood thinners for the rest of my life for my mechanical heart valve. My usual go to all my life was either ibuprofen or aspirin for pain or headaches. Now that I have been on a blood thinner for a year, my only choice seems to be Tylenol/acetaminophen... I find that if I take anything with acetaminophen, I have night terrors and my husband has to wake me bc I am yelling and thrashing in bed... I can't seem to wake myself up... this happened tonight after I took sinus medication with acetaminophen. I went to bed after 2 hours of taking it... found myself in the worst horror/slasher dream... and when I was woken up... I hallucinated for 10 minutes and saw evil things in my room that weren't there. I had to get out of bed and walk around the house for awhile. I will have to stay up and hope this wears off soon. This has happened a few times now and I am damn sure it's the acetaminophen. I will never take it in the evening again!

I broke my rib and take tylonal to help me sleep. I have always taken it for any kind of pain. Well, all a sudden this go around every night I have the same horrific dreams. I am drowning. It's horrible!

I had a night terror again last night! They are horrible, leaving me with a racing heart, shaken and anxious. These are not regular nightmares. They are vivid, detailed and terrifying. I usually wake screaming and with my husband trying to calm me. Recently, I’ve even gotten out of bed and thought I was somewhere else. These are definitely caused by taking Tylenol in the evening, within a few hours of bed. I have also begun noticing that I get a fuzziness if taking it during the day. These are standard 500 mg caplets!
It is very concerning as Tylenol is my cure for migraines.

It makes no difference in my case whether it has the red color coating or not. Extra strength acetaminophen gives me vivid, and usually weird, dreams. Being on a blood thinner gives me no choice on over the counter pain medication though. On a lighter note this may be how Tim Burton gets his movie ideas.

Yes, after taking red coated Tylenol I had vivid scary dreams.. I take no other medications. It was so real and vivid I now stay away from them.

I am glad to see this. My mom has been hallucinating like crazy after I switched her to the extra strength red tylenol. No more. I am taking her off.

My brother gets bad back pain and when he takes Tylenol extra strength, he get really bad hallucinations that will last up to 20-30 minutes. I thought he was the only one till I saw this forum.

Same thing. Hardly ever take pain pills or Tylenol. Thought I was going crazy. Took 650mf Walgreen brand Acetaminophen. Happened 3 times before I narrowed it down to this caplet. Terrifying! I am an educated pharmaceutical rep recovering from a hip replacement and am NOT NUTS. I see my doc tomorrow for a follow up appointment and am afraid to tell him. He’s an old guy and will think I’m crazy.

I have had the same experience with the red-coated extra strength Tylenol! I thought I was just super tired, so I decided to look it up and found this forum. I think I'll go back to the uncoated and only use these during the day. My dreams are like movies and hard to wake up from. Anyone know what it is in the coating that causes the dreams. I can't remember having the dreams with uncoated Tylenol.

My grandfather recently had spinal surgery and was given 100 tablets of the red pain reliever stuff. It’s been a week and they are about half gone. He’s been seeing spiders and we don’t see them. He describes them as black-and-white, fast, INVISIBLE, spiders. He believes they are there and has been trying bomb their room with the bug stuff. It’s gotten bad, and we don’t know what it is. Should we bring him to the doctors or what? Is it the pain relievers? Please give a reply.

So i haven’t had a dream in about a year and a couple days ago I’ve had this neck pain so i took 2 extra strength 500mg tablets. Went to bed and had a dream so vivid, i had to tell myself for about 30 seconds it was a dream to wake up. The next morning i thoiught it was weird because i haven’t had a dream in a while and sure enough, last night i took 2 tablets and same thing. Horrible dream last night. There has to be something about these causing dreams because when i take Advil no dreams at all

I had such a vivid scary dream last night after taking extra strength red coated tylenol in middle of night for a headache. i have no health issues and take no other medications. I woke up literally crying and very upset. took hubby awhile to wake me out of dream.. I'm not quick to take anything for headache . Had been fighting a dull headache for a couple of days, it was getting worse in middle of night.. I have never had any issues like this.

I thought i was crazy for this! I don't hallucinate, however my dreams are sooo vivid and creepy! Only when I take the red tab extra strength. Has anyone found out a reason for this? I've spoken to my Dr and he just looked at me like I was crazy.
