Interaction Between Vyvanse and Zofran: What You Need to Know
As a 19-year-old female, standing at 5 feet 3 inches tall and weighing 130 pounds, I manage a condition known as POTS. Currently, my medication regimen includes Vyvanse and Lyrica. I've been considering adding Zofran to my treatment plan to address nausea. However, upon researching potential drug interactions, I discovered that combining Zofran with Vyvanse may pose a risk for heart-related issues. I would like to know whether this is a serious risk or if such cases are relatively uncommon. Additionally, what is the recommended time gap between taking these medications?

Combining Vyvanse (lisdexamfetamine) and Zofran (ondansetron) is a valid concern, especially given your existing condition of POTS, which can affect heart rate and blood pressure. Here’s what you need to know:
Main Points
- Potential Risks: Taking Vyvanse alongside Zofran can, in some cases, lead to increased heart rate or other cardiac effects, but these instances are not exceptionally common.
- Timing Considerations: It's generally advised to space these medications apart as a precaution.
Explanation
- Vyvanse is a stimulant medication often used for ADHD, which can elevate heart rate and blood pressure. Zofran is an antiemetic used to prevent nausea, and while it is generally well-tolerated, there have been some reports of heart-related side effects, especially in patients who may already have cardiovascular concerns.
- In patients without any heart problems, severe reactions are uncommon, but since POTS can complicate cardiac function, it's wise to be cautious.
Recommended Next Steps:
- Monitoring: If you decide to proceed with taking Zofran, closely monitor how you feel, particularly regarding your heart rate, any dizziness, or other unusual symptoms. Note these observations and share them with your healthcare provider.
- Timing: Maintain a gap of at least 2 hours between taking Vyvanse and Zofran to minimize potential interactions. For instance, you could take Vyvanse in the morning, and then Zofran later in the afternoon if needed for nausea.
- Consultation: Even though you requested to avoid healthcare consultations, I recommend discussing the introduction of Zofran, specifically vis-a-vis your personal medical history, with your prescribing physician. They will have a comprehensive understanding of your health profile and can provide tailored guidance.
Approaching this combination with caution is essential, especially considering your POTS condition. Please feel free to ask more questions or share updates on how you feel!

Should I Consult My GP About My Increased Anemia After Monoferric?
I have a complicated medical background, so I’ll try to detail everything relevant, even if it turns out to be lengthy. I am a 26-year-old assigned female at birth, and I was administered 1g of Monoferric intravenously around ten days ago. I understand that it generally takes about six weeks to see the full effects, but I had some blood tests conducted two days ago that suggest my anemia may have worsened. Since my hysterectomy, I haven’t noticed any indications of internal bleeding, like blood in my stool or vomit. However, I’ve been experiencing common symptoms of anemia, which seem to have intensified in the last five days, likely due to the warmer weather. To illustrate the changes in my bloodwork, I’ve compared results from fourteen days prior to the infusion with my most recent tests: - RBC count has dropped from 3.56 to 3.52 x 10*12/L - Hemoglobin decreased from 117 to 110 g/L - MCV increased from 97 to 101 fL - RDW has risen from 16 to 16.9% The tests for Ferritin, iron levels, and iron saturation were not redone, but immediately before my infusion, they measured at 12, 8, and 0.15, respectively. Both Folate and B12 levels were normal in my previous results. I also have generalized Myasthenia Gravis for which I receive IVIG therapy; my last treatment was 16 days ago, with a dosage of 70g every three weeks. Additionally, I have been consistently taking Imuran (150mg) and Mestinon (180mg XR twice daily) for five years with no changes to my dosage or schedule. I am not on prednisone or any other steroids. Furthermore, I manage mild hypothyroidism with Synthroid (50mcg), and my TSH levels have remained stable and within a normal range over the past four to five years. I undergo blood tests bi-monthly to monitor my Imuran therapy, including a complete blood count (CBC), which often leads to jokes among my friends about how all my results consistently fall within normal ranges. Over the last five to six months, however, I have only noticed a decrease in hemoglobin and RBC counts. My RDW tends to be slightly elevated, around 14.5%, but my MCV has never been flagged as abnormal. My inquiry is whether these findings might indicate macrocytic anemia, despite the values appearing on the milder side. Given my past lab results have always been stable, would it be prudent to inform my physician about my concerns, especially considering my intricate medical history and absence of known risk factors for macrocytic anemia?
Unusual Digestive Reactions to Certain Foods
Over the past few years, I, a 29-year-old male, have experienced peculiar digestive reactions to seemingly random foods, but research hasn’t clarified the matter for me. My symptoms are particularly pronounced after consuming ginger, and I’ve also had reactions once each to shrimp, guacamole, and pepperoni pizza, even though I have enjoyed those items in the past without any problems. Typically, my reaction begins with a tingling sensation in my mouth following ingestion, which is subsequently followed by several hours of intense stomach pain and bloating. While I do suffer from chronic bloating, these episodes are significantly worse. Given my allergy to sulfa, I considered that sulfur might be the culprit, especially since I tend to feel slightly unwell after eating homemade eggs—specifically those made by me—though other sulfur-laden foods, like red meat and garlic, don’t seem to affect me at all. Additionally, I have an issue with collagen (hypermobile Ehlers-Danlos syndrome) that I believe contributes to reduced motility, but none of the doctors I’ve discussed this with have shown much interest in exploring the matter or its potential consequences. Could there be a pattern linking these foods? Might this indicate an allergy even in the absence of anaphylactic reactions? I do experience oral allergy symptoms when consuming apples and carrots due to a pollen allergy, adding another layer of complexity to my situation.
Unexplained Gastrointestinal Distress for Three Months
Greetings everyone, I’m a 21-year-old assigned female at birth living in the UK and I have not traveled outside the country. My medical background includes Chronic Fatigue Syndrome/Myalgic Encephalomyelitis stemming from Glandular Fever, migraines, Irritable Bowel Syndrome, and a lactose intolerance that surfaced in 2022, along with debilitating menstrual cramps. Currently, my medication regimen consists of Omeprazole, Propranolol (used for migraine management), Desogestrel, Promethazine Hydrochloride, and Duloxetine. Starting around April of this year, I have experienced approximately six bouts of what feels like intense stomach or bowel issues. During these episodes, I am struck with excruciating abdominal pain that is often accompanied by diarrhea and profuse sweating—I’m talking about beads of sweat streaming down my face. The level of pain has been so high that it makes me dizzy, even giving me the sensation of nearly losing consciousness. When this discomfort occurs, concentrating on anything else becomes nearly impossible. My most recent episode was particularly severe, rendering me unable to leave the bathroom for a solid two hours. While I wasn’t experiencing diarrhea throughout the entire time, it did occur frequently during those two hours. The pain remained constant but fluctuated in intensity in waves. Additionally, my heart rate spikes significantly during these episodes. I consulted my GP, underwent blood tests, and discovered my white blood cell count was slightly elevated, with a CRP level of 43. It’s worth noting that I have not had a normal CRP level since contracting mono; the highest it has been in the past was around 30, which coincided with instances of tonsillitis. Moreover, I wasn’t experiencing an episode at the time of testing. My GP was perplexed about the underlying cause of my symptoms; we excluded any connection to my menstrual cycle since I’ve been on Desogestrel and haven’t had a period in a few years. As a follow-up, she has referred me for a stool analysis and a coeliac disease test (which I previously tested negative for in 2019), as well as a re-evaluation of my CRP level, among other tests. The wait for my results won’t conclude until mid-August, which is why I’m reaching out to this community—I’m feeling quite anxious about the whole situation. I would greatly appreciate hearing from anyone who might have encountered a similar condition or could offer advice, as I’m genuinely fearful about the possibility of these episodes recurring. I’m also open to answering any questions you might have. In case it’s pertinent, I have noticed a weight loss of about a stone (14 pounds) since this ordeal began. My appetite tends to suffer during these episodes and in the following days. The only potential trigger for my latest incident could be that I consumed some rich cream (like double or whipping cream). Given my lactose intolerance, I’ve come to realize that cream is particularly troublesome for me. I only had a small amount (unaware it was cream at the time), and I’ve never reacted this severely before, even after larger quantities. I hope this explanation is clear. I apologize if I'm rambling—articulating my thoughts can be a challenge!
Could This Be a Peritonsillar Abscess or Just Severe Strep Throat?
I’m a 26-year-old female with a history of two cesarean sections, a gallbladder removal, and a tonsillectomy performed two decades ago. Currently, I take Adderall, Advil, and doxycycline due to an acne flare-up, along with amoxicillin prescribed for strep throat. Recently, I've been concerned about something at the back of my throat. Although I had my tonsils removed, I've noticed one side appears to have a purplish vein-like structure along with some cysts, while the opposite side has what looks like a pimple. After visiting urgent care, the medical staff prescribed amoxicillin for a presumed strep infection without conducting a strep test. I’m left wondering if this is indeed related to strep throat or something different altogether. Additionally, there’s a problematic wisdom tooth on the same side, but it’s been causing issues for several years now.
Navigating a Mild UTI Flare-Up After Antibiotics: Seeking Insights
Hello everyone, I'm a 28-year-old male residing in India who generally maintains a healthy, active lifestyle. About two weeks prior, I began experiencing mild discomfort during urination shortly after swimming. Initially, I attributed the irritation to chlorine exposure, but soon I faced additional symptoms including fatigue, abdominal tenderness, a slight fever, and ultimately, hematuria—blood in my urine—and some unusual tissue during urination. Alarmed, I visited a physician who carried out a comprehensive assessment: - A urinalysis and culture identified an E. coli infection, which responded to the antibiotic Ofloxacin (Zanocin). - An ultrasound discovered Grade 2 changes in my right kidney, indicating some minor damage but no stones or blockages present. For treatment, I was prescribed Zanocin OD for a duration of 10 days, which I successfully completed. Additionally, I managed my pain with medication and increased fluid intake. By the end of the treatment, my symptoms had completely subsided. Fast forward to last Thursday, four days ago, when I wrapped up my antibiotic therapy. I followed up with my doctor on Monday, expressing that I felt back to normal. However, today I noticed a sudden onset of: - A slight urgency to urinate, - A mild sensation of incomplete emptying, - A single episode of cloudy urine accompanied by pinpoint bright red spotting and some tissue discharge. Thankfully, there is no significant pain, burning, or fever present. Upon my Monday appointment, my urologist recommended taking Fosfomycin (Fosirol) weekly for three weeks to avert any further infections. I’m set to take my first dose tonight. At this point, I'm left with a few lingering questions: - Is it common to experience a flare-up like this during the recovery phase, or should I be concerned about a potential reinfection? - Could resuming my gym routine, particularly after a heavy back workout a few days ago, be a contributing factor? - Is it typical for the urinary tract and bladder to remain irritated even after the eradication of bacteria? While my symptoms aren't rapidly deteriorating, I can't shake the anxiety over possible recurrence or long-term implications, especially given the kidney involvement. I would greatly appreciate insights from anyone, specifically those who may have gone through similar experiences, regarding recovery from UTIs post-antibiotics in men. Thank you for taking the time to read this and for any support you can provide.
