Understanding Unusual Sedation from Methylphenidate: A Personal Experience
Can anyone shed light on a potential explanation for what occurred? I did some research but only found a single article about a similar situation involving a young boy, and my doctor is also puzzled by my experience. I was prescribed Medikinet, 60mg twice a day, after using methylphenidate in various brands for about two years. This was my first time on Medikinet. As for me, I am a 36-year-old female, weighing 46kg with a height of 171cm. I have been diagnosed with multiple conditions: autism, ADHD (combined type), PMDD, anorexia nervosa, osteoporosis, peripheral neuropathy, a hiatal hernia, chronic neutropenia, and leukopenia. At present, I am not taking any other medications except for occasional paracetamol or Movicol. My transition to Medikinet was prompted by medication shortages. The initial two days were promising; my ADHD symptoms showed improvement, and I had no side effects. However, starting on the third day, approximately two hours post-morning dose, I experienced extreme sleepiness and drowsiness that felt unusual, resembling medical sedation rather than general fatigue. I had encountered sedation from ADHD medications before, but this reaction was notably more intense. During the worst of it on the first day, I struggled to talk or move. Though I could force out a response, it was challenging. On the following day, which I believe was around day four or five of taking Medikinet, the sedation intensified to a concerning level. The sedation would last about two hours each time, overwhelming me to the point of being unresponsive. I could undergo a pain test that involved pressing on my collarbone—I felt it and could manage basic sounds, but maintaining eye contact proved nearly impossible. I opened my eyes when addressed but lacked the energy to look around or keep them open. Despite being aware of my surroundings, I could not react, feeling as if I were fading in and out of consciousness. Emergency services were called to assess my condition since my heart rate had peaked over 160 beats per minute, and the doctor was considering possible complications like a pulmonary embolism, although no abnormal lung sounds were detected. Approximately 20 minutes later, I began to regain consciousness, eventually becoming more responsive, though still somewhat drowsy. At that point, I felt it was no longer an emergency, and the ambulance was canceled after I declined further assistance. It took me about two hours to fully recover after the doctor had left. A wave of sedation returned, causing my legs to buckle again, rendering me immobile for roughly 2-3 minutes. My heart was racing, and I feared it might be a heart attack. Once I regained the ability to move, I crawled back to bed and remained there for a couple of hours until I could muster the energy to get something to eat and drink. I had the necessary ECG afterward, followed by routine blood tests the next day, all of which yielded normal results. I also did not take the second dose of Medikinet that day as a precaution, and my dosage was reduced for the following day. Fortunately, I didn’t experience such extreme sedation again. I had been taking Medikinet on an empty stomach initially, unaware that it should be taken with food. It seems the absorption rate might peak too quickly without food, but after making that adjustment, I found the medication to be more effective in managing my ADHD symptoms without the excessive sedation. It's perplexing that such extreme sedation occurred. Does anyone have insights into what could have caused this unusual reaction?

It sounds like you've had a challenging experience with Medikinet, leading to extreme sedation that you've accurately described as concerning. Your situation is notably complex given your multiple health conditions and history with ADHD medications. Let's unpack some potential explanations and focus on actionable steps moving forward.
Summary of Key Points:
- Sedation Reaction: Extreme sedation can occur with methylphenidate, especially during dosage adjustments or if taken improperly.
- Food and Medication Interaction: Taking Medikinet on an empty stomach may affect its absorption and peak levels, contributing to side effects like sedation.
- Monitoring and Adjustments: It's essential to continue monitoring your response to medication and make adjustments as necessary.
Explanation:
Methylphenidate, including the brand Medikinet, is a stimulant primarily used to treat ADHD. It can, however, produce paradoxical sedation or pronounced drowsiness in some individuals—particularly when starting a new medication or adjusting doses. Factors contributing to your experience may include:
- Dosage and Tolerance: Since this was your first time on Medikinet, your body may not have fully adjusted to the new formulation or dosage (60 mg twice a day) yet.
- Absorption with Food: As you discovered, taking methylphenidate on an empty stomach can lead to quicker absorption, potentially resulting in higher peak plasma levels, which might enhance side effects such as sedation.
- Interactions with Existing Conditions: Your other health conditions, particularly chronic neutropenia and anorexia, may also predispose you to heightened sensitivity to medications.
Next Steps:
- Continue Medication with Food: Ensure you consistently take Medikinet with meals to help regulate absorption and reduce side effects.
- Monitor Symptoms: Keep a detailed diary of your symptoms, medication intake, and any side effects. This will be valuable for you and your healthcare provider in adjusting your treatment plan.
- Communicate with Your Doctor: Since you’ve already experienced concerning symptoms, maintain open communication with your healthcare provider. Share your symptom diary and discuss any ongoing side effects or changes you notice.
- Consider Dosage Review: If sedation remains an issue or worsens, have a conversation about potentially adjusting your dosage or exploring alternative ADHD medications that might work better for you.
Your experience is valid, and it’s important to address your concerns with your healthcare team. By taking these steps, you can help ensure that your treatment plan is as safe and effective as possible while managing your ADHD symptoms. Remember, you are not alone in this journey, and it’s commendable to advocate for your health needs.

Strange Jelly-Like Substance Observed from Wound
I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
