Could Zofran Administration Have Triggered Torsades?
A few weeks ago, I found myself in the hospital following a head injury. I was suffering from severe nausea, prompting the medical team to administer what I believe was Zofran through an IV. Although I am uncertain of the exact dosage, I recall the nurse providing me with multiple vials, which seemed excessive compared to the solitary tablet I had been receiving earlier. Shortly after the infusion, medical staff observed that my heart rate significantly elevated and continued to escalate. Concurrently, I began experiencing intense dizziness, to the point where I feared I might faint. They applied numerous adhesive patches across my body from my feet to my chest to conduct an EKG, seemingly growing more anxious as they urgently summoned a doctor multiple times. At that moment, my heart rate was approximately 200 beats per minute, and I could distinctly feel my heart racing uncontrollably. This left me in a state of panic, worrying that I was on the verge of a heart attack, and the surrounding chaos did not help to ease my anxiety. After about 5 to 10 minutes, my heart rate finally began to stabilize and gradually decrease. The physician later reassured me that what I experienced was a recognized side effect and not a cause for alarm. As my other injuries begin to heal, the incident has increasingly troubled me. I find myself concerned about the events that unfolded, unsure about the potential for it to recur. For context, I am a generally healthy woman in my early thirties, admitted solely for my head injury. I had not consumed much food in the prior two days and had actually vomited about half an hour before receiving the medication.

It sounds like you had a very distressing experience during your hospital stay, and it's completely understandable to feel anxious about what happened. It's important to address both your immediate concerns and any lingering worries you may have.
Main Points:
- Zofran (ondansetron) may lead to changes in heart rhythm, but such effects are usually not severe.
- Your symptoms of increased heart rate and dizziness could be attributed to a variety of factors, including the medication, dehydration, and anxiety.
- It's essential to monitor how you feel and seek clarity on medication use, especially in future situations.
Explanation:
Zofran is used to treat nausea and vomiting and is generally safe for most people. However, it can affect heart rhythm in some patients, potentially leading to a condition known as Torsades de Pointes, which is a type of fast, abnormal heart rate. Factors such as dehydration (from lack of food and vomiting), electrolyte imbalances, and individual sensitivity to medication can also increase this risk. Your body has likely been under significant stress from the head injury and any accompanying factors (like dehydration), which might have contributed to your symptoms.
Next Steps:
- Stay Hydrated: Increase your fluid intake, particularly if you've been feeling unwell or have had reduced food intake. Electrolyte solutions can also help maintain balance.
- Follow-Up Monitoring: Keep track of any recurring symptoms, such as rapid heart rate or dizziness, especially after taking medications. This information will be helpful for any healthcare provider you consult in the future.
- Clarify Medication Use: If you know you have an appointment coming up, it may be beneficial to ask your healthcare provider about the use of Zofran and other medications, especially regarding dosages and side effects.
- Manage Anxiety: Considering the panic you experienced, you might find it helpful to speak with someone about your feelings. Techniques such as deep breathing, mindfulness, and journaling can also help manage anxiety in these situations.
Remember, being proactive about your health and understanding your medications can empower you and ease your concerns. If you feel very anxious or notice any alarming symptoms, it’s wise to reach out for professional support.

Chronic Nausea: A Comprehensive Overview
Greetings! I'm a 20-year-old individual, standing at 5'9" and weighing 320 lbs. My medical history is quite extensive, including diagnoses of bipolar disorder, panic disorder, level 1 autism, binge eating disorder, polycystic ovary syndrome (PCOS), metabolic syndrome, and non-alcoholic fatty liver disease (which my gastroenterologist is monitoring, although it’s not currently critical). I also deal with gastritis, acid reflux, irritable bowel syndrome (IBS), sleep apnea, and insomnia. Unfortunately, my gastroenterologist doesn’t seem very accommodating; I feel the need to engage in my own research and self-advocacy because she often dismisses my concerns. She attributes my nausea and discomfort to my medicinal cannabis use. However, I've only been using cannabis for three years, while my symptoms have persisted for about six years, showing no improvement during periods without it. In fact, cannabis actually helps me manage my food intake and alleviates some of the discomfort. If you require any further details, feel free to ask! **My Symptoms Include:** **Nausea and Vomiting** - Frequency: Nausea occurs 4–7 days per week. - Episodes of vomiting happen approximately 3–5 times weekly. - Primarily occurs in the mornings upon waking. - **Triggers:** - Eating breakfast - Chewing food - Gagging, coughing, or dry heaving - Relief: Vomiting typically offers fleeting relief, but may include regurgitated food that hasn't digested from previous meals consumed 9–12 hours prior. - **Associated Symptoms:** - Feeling overheated just before vomiting - Weakness and shakiness - During episodes of nausea, I experience significant drowsiness, sometimes severe enough that it's hard to stay awake, even while driving. **Swallowing Difficulties and Reflux** - I have suffered from acid reflux since childhood, which has progressively worsened over time. - **Current Symptoms:** - Severe burning sensation in the chest and throat - Chest pain - Nighttime and morning reflux incidents - Antacids only offer brief respite - **Dysphagia (difficulty swallowing):** - Intermittent issues, particularly with pills or tablets, often feeling as though they get lodged in my throat and not alleviated by drinking water. - Occasionally, swallowing liquids and saliva can also be difficult. - Symptoms sometimes exacerbate when lying flat. - I frequently wake with a sour or bitter taste, accompanied by coughing or a burning sensation in the throat. **Abdominal Pain and Bowel Patterns** - I experience cramping similar to menstrual cramps, usually localized in the lower abdomen, lower back, and pelvic region. - These cramps can be intermittent, particularly prevalent at night, causing occasional but severe discomfort. - My bowel movements are irregular, alternating between constipation (with hard, dry stools) and diarrhea (with loose, watery stools). - Cramping sometimes alleviates post-bowel movement. **Autonomic and Systemic Symptoms** - There is a constant feeling of fatigue. - After eating, I often feel excessively sleepy. - During flare-ups, sleep may extend for lengthy periods, sometimes lasting entire days. - During nausea episodes, I experience: - Significant weakness - Shakiness - Near-fainting sensations - Episodes of heart racing or pounding. - There are instances of urinary incontinence when sneezing or coughing, along with frequent urges to urinate with minimal output. **Gastrointestinal Reflex Symptoms** - Vomiting can sometimes be instigated by bowel movements. - I have occasional involuntary bowel movements concurrent with vomiting episodes, typically associated with intense nausea and systemic symptoms.
Persistent Ear Sensation Following Influenza
Seven days ago, I received a positive diagnosis for the flu, despite having been vaccinated beforehand. After starting antiviral medication within the initial 24 hours, my severe symptoms seemed to diminish within roughly three days. Nevertheless, I'm still experiencing a continuous sensation of fullness or muffling in my ears, which hasn’t seen any sign of improvement. The intensity of this sensation varies, but overall, it appears to be worsening. Additionally, I have been having occasional bouts of dizziness linked to the pressure in my ears. This situation is concerning for me, especially considering my childhood history with poorly developed Eustachian tubes that were never treated. This condition caused repeated ear infections and temporary hearing loss until I was approximately 3 to 4 years old. Following that, I went through eight years of speech therapy to help me read and articulate properly. Considering my background and the escalation of my current symptoms, I am questioning whether I should seek a professional evaluation. Alternatively, could this just be a common post-viral inflammation that might resolve on its own? My fiancé also contracted the flu and mentioned that his muffled hearing disappeared two days after he exhibited his first symptoms.
Unexpected Wrist Swelling and Bruising Without Injury
I hope this isn't too trivial, but I find myself puzzled by a recent incident. I'm a 33-year-old female, I don’t smoke, only drink occasionally, steer clear of drugs, and have no known health issues. This past Saturday, while I was seated on the floor, my left arm was propped up with my palm resting on the ground. Suddenly, I experienced a tingling sensation that creeped into my thumb, accompanied by a slight discomfort rated around 2 out of 10. Soon after, I noticed that my wrist was swollen and, over time, developed a light bruise. The swelling subsided by the next day, but I’m left with a faint bruise that is still somewhat noticeable two days later. It's strange to think that something like this could occur when I was simply sitting down.
Persistent Gagging from Mucus Discomfort
At 32 years old, I experienced a series of debilitating health issues throughout the fall and winter of 2024. What began as a typical cold escalated into secondary pneumonia, and during this time, I also strained a muscle in my abdomen due to relentless coughing—all while battling a severe stomach virus. That was an utterly dreadful experience in the emergency room. Afterward, when I seemed to have recovered and was merely left with a residual cough, I unfortunately contracted COVID-19. In the year that has followed, I've often found myself suddenly gagging, as if something is lodged in my throat or coating it. Typically, I discover that it's a mass of what I believe to be phlegm. I find that drinking water does little to alleviate this sensation; the mucus must be forcibly coughed out, which is often painful and leads to gagging. Curiously, I haven't noticed any clear connection between this issue and my hydration levels or the time of day. Despite trying various new medications this year and successfully managing my elevated A1C level, this problem has remained unchanged. While it's not frequent enough for me to consider it a significant part of my medical history, the episodes are common enough that every time I finally manage to expel a lump of mucus, I am left pondering, "What is causing this?" So I find myself wondering, "Is this a common condition?" and "Will I have to deal with this for the foreseeable future?"
Inquiring About Tuberculosis Treatment and Isolation
Age 23, Female, with no prior health conditions. Situation: Pulmonary I recently received a positive tuberculosis test indicating it's currently active, with a result of +1 AFB. Surprisingly, I am exhibiting no symptoms whatsoever. I'm currently undergoing treatment, which has been in effect for the past two weeks. However, my doctor had to suspend my medication for four days due to elevated liver enzyme levels. At this moment, I am in the process of gathering sputum samples for further testing. I am eager to learn when individuals typically conclude their isolation period. This experience has left me feeling anxious and isolated. Any words of support would be greatly appreciated. Thank you.
