Concerns Regarding Doxycycline and Steven Johnson Syndrome
A 50-year-old woman from the USA has been contemplating potential exposure to bites from deer flies or horseflies, which may have contributed to her current health situation. She has a history of being prediabetic and recently underwent surgery for kidney stones, which hasn’t gone smoothly, leaving her fatigued and in recovery. Currently, she’s awaiting the results of laboratory tests and has been prescribed doxycycline. However, she has had a troubling experience with antibiotics in the past, often experiencing adverse reactions to various medications. Given the prescription for doxycycline linked to possible exposure, she feels anxious about the risk of developing Steven Johnson syndrome. Is there any data available that addresses the chances of this condition arising from the use of doxycycline?

It's understandable to have concerns about adverse reactions to medications, particularly with doxycycline given your history. Steven Johnson Syndrome (SJS) is a rare but serious condition that can occur in response to certain medications, including some antibiotics. However, the risk of developing SJS from doxycycline is quite low compared to other drugs.
Key Points:
-
Risk of Steven Johnson Syndrome (SJS): Doxycycline is not among the antibiotics most commonly associated with SJS. While any medication can potentially cause SJS, its occurrence with doxycycline is very rare. Factors such as individual genetic predisposition and personal medical history may influence risk.
-
Monitoring Symptoms: Given your prior adverse experiences and current health status, it’s important to be vigilant for any signs of an allergic reaction. Early symptoms of SJS may include flu-like symptoms, followed by a painful rash that spreads and blisters.
-
Overall Benefits: Doxycycline can effectively treat infections that may otherwise complicate recovery from your surgery, potentially aiding your health overall.
Next Steps:
-
Self-Monitoring: Keep an eye on any new symptoms, particularly skin reactions or flu-like signs, especially during the first few days of treatment.
-
Hydration and Rest: Focus on staying well-hydrated and getting adequate rest to support your recovery from surgery.
-
Communicate Concerns: If you do notice any concerning symptoms (such as a rash, fever, or unusual fatigue), contact your healthcare provider promptly to discuss your symptoms and consider alternative treatments if necessary.
-
Document Your Experiences: Maintain a log of any side effects you experience while on doxycycline. This information can be valuable in discussions with your healthcare provider.
Stay informed and proactive about your health while continuing to communicate openly with your healthcare team! If you have further questions, feel free to ask.

Reflecting on Tonsillectomy: A Deep Dive into My Concerns
Hello everyone, I hope to spark a conversation around an experience I've recently had. Just four days ago, I underwent a tonsillectomy. For a significant amount of time, I had one tonsil noticeably larger than the other. This larger tonsil held a substantial crypt that often trapped food particles, leading to discomfort or the formation of stones daily. To manage this, I regularly used a tool similar to a pimple extractor each night to clear it out. Despite this routine, I frequently experienced irritation, dryness, and soreness when swallowing, which prompted me to seek out a solution after enduring it for four months. Importantly, these troubles never escalated to severe illness or infections; they were primarily annoying symptoms. In contrast, my smaller left tonsil behaved normally without any issues. However, I received advice suggesting that it might be prudent to remove both tonsils to prevent potential complications in the future, a sentiment echoed by my ENT specialist who was rather indifferent, stating I could either choose to live with them or opt for surgery. Upon completion of the procedure, I initially felt okay, but as the days unfolded, I sank into a profound sense of regret and dread. I came across various research studies indicating a potential rise in cancer risk—up to a 10% increase—following tonsillectomy. The thought of having potentially jeopardized my health weighs heavily on me, and I find myself in a constant worry loop about the decision I made. I’ll provide a link to one of the studies conducted in Sweden for those who are curious. It's worth noting that while numerous factors contribute to cancer risk, I can't shake the feeling that I might have just exacerbated my own by removing my tonsils. Furthermore, I've seen numerous online comments reinforcing the idea that tonsils serve a protective role in the body and shouldn't be removed lightly. Adding to my anxiety is the fact that I had expressed a desire for a biopsy of the enlarged tonsil after surgery, particularly because of its size and the symptoms it caused. However, upon following up, I learned from my surgeon that he opted to biopsy the other, smaller tonsil—one that had never caused me any concern—since he believed the larger tonsil appeared normal and healthy. Did I potentially eliminate a perfectly good tonsil? Was this decision entirely misguided? I am left feeling really anxious and uncertain about whether I made a grave mistake in opting for this procedure. For those interested, here’s the Swedish study that I referenced: https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-023-02902-x And here's a related study discussing breast cancer risks post-tonsillectomy: https://pmc.ncbi.nlm.nih.gov/articles/PMC9350012/
Seeking Help with Persistent Genital Bumps
Hello everyone, I'm reaching out to share my situation. I’m a 19-year-old female, standing at 5 feet 4 inches and weighing around 100 pounds. I am on a variety of medications, including Pristiq at 100 mg, Guanfacine at 2 mg, Caplyta at 21 mg, Valacyclovir at 500 mg, and Spravato (Esketamine) at a dose of 84 mg. Lately, I’ve reduced my use of cannabis due to the esketamine treatments. I’m feeling quite anxious about posting this, but I believe Reddit is a supportive space for questions like mine. I have a diagnosis of genital herpes, as I am prescribed Valacyclovir, and I am uncertain whether the symptoms I’m experiencing are related to this condition. For the past month, I have noticed small, painless bumps around my genital area that are sometimes filled with a fluid. I doubt they are ingrown hairs, as they haven’t shrunk or disappeared despite my efforts. My last outbreak was particularly difficult, lasting about two weeks, but that fully resolved after approximately three weeks. I am diligent about taking my medication alongside 2000 mg of lysine every day, so I’m not inclined to think this is another herpes outbreak, although I could be mistaken. I often find myself under a lot of stress, and I know that stress can play a role in triggering herpes outbreaks. Part of me wonders if I'm overreacting to this situation. However, I feel quite helpless when it comes to addressing these bumps, and I do not want this to be a recurring issue for me due to stress. Apologies for the lengthy message, and thank you for any insights you can share!
Worries Surrounding a Mole
Demographics: - 35-year-old male - Height: 6’1” - Weight: 240 lbs - Hasn't smoked in over 7 years - No significant medical history Greetings everyone, My husband’s mole has become a significant source of anxiety for me. At 35 years old and with no medical issues in his past, he seems healthy. Interestingly, his mother has multiple moles, having had 30 to 50 of them removed, yet none were found to be harmful. His father also had a mole excised from his scalp due to sun exposure. I only recently noticed this particular mole, and my concern arises from its asymmetrical shape and the presence of a dot at its center. We are currently awaiting feedback from a physician, but the worry is affecting my sleep. If anyone could offer insights or opinions on this matter, I would be very grateful for your assistance.
Seeking Guidance for Treatment Options
Hello everyone, I’m reaching out for some assistance regarding my husband, who we believe is suffering from Auto-Brewery syndrome. Finding a supportive medical professional has been incredibly tough; it seems like many simply dismiss our concerns, assuming he's hiding alcoholism. Last year, he was diagnosed with sleep apnea after I persistently expressed my worry about his excessive sleeping and episodes of confusion, including unsafe driving. After several months using a CPAP machine with little improvement, I took him to the emergency room in May following another episode of confusion. To our shock, the medical team discovered he had a blood alcohol concentration (BAC) of .4, despite him having consumed only one hard seltzer the evening before. The physician accused him of being dishonest and suggested we look into substance abuse counseling. We have had extensive discussions about this and both wish the solution was as straightforward as entering rehab; however, the reality is more complicated. To clarify, he has refrained from drinking alcohol since that incident and hasn't been much of a drinker throughout our decade together. In my concern over his confusion, I had previously consulted his primary care physician. Blood tests indicated elevated liver enzymes, but the doctor attributed this to the need for weight loss—he was slightly overweight by about 20-25 pounds. Post-ER visit, he adopted an extremely low-carb diet, resulting in a weight loss of 30 pounds. Remarkably, his sleep apnea seems to have resolved, and he is significantly improved. Unfortunately, efforts to find a physician willing to assist us have been met with skepticism. Recently, he attended a dinner with our vegetarian neighbors, where he felt compelled to try some lentils and chickpeas. Upon returning home, I had him test his breath with a breathalyzer, and he registered at .09. It was clear he had not consumed alcohol; I’d been with him all day. This has left him feeling understandably crushed, as he had hoped that perhaps on the day we visited the hospital he'd simply overindulged unknowingly. Is this truly what our lives must consist of now? I’ve heard there are treatment options available, yet we can’t seem to get anyone to take us seriously. The entire journey of uncovering this situation has been daunting and frightening, filled with months of him appearing disoriented and feeling as if I was alone in believing there was an issue, almost like caring for someone with dementia. While the past few months on his new diet have restored some of the essence of my husband, I can’t help wishing he could occasionally enjoy sweet potatoes or fruits. Are we really destined to remain in this predicament?
Comparing Barrow's and Burow's Solution for Chronic Ear Issues
Age: 35, Gender: Female, Height: 5'3", Weight: 150 lbs, Ethnicity: Caucasian, Condition: chronic swimmer's ear, Duration: intermittent for over 10 years, Current medications: none except for hydrocortisone/acetic acid otic drops, Alcohol use: no, Smoking: no, Recreational drug use: no. For over a decade, I've been dealing with persistent itching in my ears. This discomfort is not continuous; it fluctuates over time. Last year, I consulted with an ear, nose, and throat specialist who prescribed fluocinonide oil drops, which provided significant relief. In fact, it was the most effective treatment I've tried, allowing me the longest respite from itching episodes. However, after switching to a new health insurance plan, I was unable to return to that original specialist and instead saw a different ENT. This new doctor informed me that Debrox, an earwax removal aid I had been using upon a previous recommendation, was harmful, and he advised me to discontinue its use. Furthermore, he dismissed the fluocinonide oil as lacking credible scientific support. He introduced me to a concoction called Barrow's Solution, which he prepared himself. Strangely, it came without any accompanying ingredient information. The doctor claimed that this solution had previously been available through a pharmacy but became too costly for patients—while it only costs about $6 to make, pharmacies charged over $100 per bottle. So, he chose to create it himself, offering it for free to his patients, asserting it contained components similar to the hydrocortisone/acetic acid drops prescribed by my primary care doctor. Upon researching, I stumbled upon Burow's Solution, which, although it sounds similar, is not available for purchase or through a prescription. This raises questions about the authenticity and safety of Barrow's Solution. Should I have confidence in this unverified clear solution I received, labeled as "Barrow's Solution"? Given that this supposedly contains ingredients akin to the hydrocortisone/acetic acid solution, I have opted to continue using my pharmacy-purchased drops, as I have a substantial supply left. While the hydrocortisone/acetic acid drops still provide some relief, they take longer to work and can be painful. The fluocinonide drops were far superior, offering quick relief, and it's frustrating that my new ENT questions their efficacy despite them being previously prescribed by another specialist.
