Seeking Clarity on Allergic Reactions After Resuming Hormone Therapy
Greetings. I am a 24-year-old assigned male at birth (AMAB) and have been undergoing hormone replacement therapy (HRT) consisting of 2 mg of oral estradiol along with 100 mg of spironolactone taken twice daily for approximately 1.4 years without any complications. On July 5, I had to visit the emergency room due to sudden episodes of diarrhea, vomiting, and dehydration. While there, I received treatment that included intravenous omeprazole and metoclopramide, followed by a prescription for oral TMP-SMX (800/160 mg, twice a day for five days), as well as Pepto Bismol and dimenhydrinate. Blood tests indicated my white blood cell count was at 15,650 with 93.2% neutrophils. Upon completing the prescribed 10 doses of TMP-SMX on July 9, I decided to restart my estradiol regimen on July 13. Unfortunately, shortly after taking the 2 mg dose that evening, I experienced an allergic response characterized by hives, lip swelling, and slight throat swelling. An emergency department visit was necessary, where I was given IV chlorpheniramine and omeprazole. Due to stomach discomfort later, I opted to take an additional omeprazole tablet. That same evening, I resumed my intake of 2 mg of estradiol and 50 mg of spironolactone once again. The following day, July 14, I encountered a second onset of allergic symptoms mirroring the first episode, leading to another emergency department visit where I received IV chlorpheniramine, along with prednisone. I was prescribed oral forms of prednisone and chlorpheniramine for ongoing management, but I have refrained from taking these medications out of concern for gastrointestinal distress. On July 15, I took a reduced dose of chlorpheniramine (2 mg), which helped alleviate the hives and itching; however, I woke up with mild swelling in my hands, feet, lips, and face—though fortunately, my throat remained unaffected. Since that incident, the hives have diminished in frequency and intensity. I am uncertain whether these allergic reactions were triggered by the TMP-SMX, the resumption of HRT, or possibly a combination of both. Regrettably, there are no allergists accessible within my locality, and my endocrinologist offers consultation only through virtual channels. I am eager to continue my HRT but feel unsure about how to do so in a safe manner. Any guidance you could provide would be immensely helpful. Thank you for your support!

It's understandable to feel concerned about the allergic reactions you've experienced while navigating your hormone replacement therapy (HRT) and treatment with TMP-SMX. Your goal seems to be ensuring your safety while continuing your HRT regimen. Let’s address your situation clearly.
Key Points:
- You experienced allergic reactions characterized by hives, swelling, and gastrointestinal distress after resuming HRT following treatment with TMP-SMX.
- It’s essential to identify the trigger of your allergic response and manage your symptoms safely.
Explanation:
The symptoms you've described—hives and swelling—could be a reaction to either the TMP-SMX antibiotic or the estradiol from your HRT, potentially due to the stress your body has undergone after the emergency visits and treatments. Allergic reactions can sometimes emerge after medications are resumed, especially if there's an existing sensitivity.
Next Steps:
-
Monitor Symptoms: Keep a detailed log of your symptoms—note the timing of medications and any reactions you experience. This will be helpful for your healthcare provider.
-
Reassess Medications:
- Continue with Caution: If you wish to continue HRT, consider taking a lower dose and closely monitor your body's response. Notify your endocrinologist about your reactions as they may adjust your HRT safely.
- Consider Alternate Medications: Speak with your healthcare provider about potentially switching from TMP-SMX to another antibiotic if you need one in the future, as this might mitigate allergy risk.
-
Controlled Environment: Avoid triggers that could lead to allergies, which might include specific foods or environments, especially during your experimentation with medication doses.
-
Symptom Relief: Since chlorpheniramine has helped with your hives, consider a plan to use this under supervision for mild symptoms while being cautious of gastrointestinal discomfort. Taking it with food may help mitigate stomach issues.
-
Emergency Plan: Make sure you have an accessible plan for managing severe allergic reactions. This includes having antihistamines on hand and knowing when to seek immediate medical help.
-
Virtual Consultation: If possible, prioritize a virtual consultation with your endocrinologist or a local allergist (if available), to address these reactions significantly and safely manage your medications.
Remember, the goal is to ensure both your safety and your comfort while continuing your transition. Please update me on your progress or any new symptoms, and don’t hesitate to reach out for more detailed assistance.

Potential Causes of a Red, Throbbing, Warm Nose
Greetings! I am a 31-year-old female seeking insights regarding some unusual sensations I’ve been experiencing. Over the past several years, I've observed that my nose occasionally becomes irritated, turning red and feeling warm to the touch. I’m uncertain if the mild swelling is simply due to the redness enhancing its visibility or if it truly is swelling. I suspect that the slight throbbing and warmth prompt me to touch my nose, which might make the redness more pronounced. The redness is consistent and does not spread to my cheeks. Typically, this condition arises in the afternoon and appears to diminish by the evening. I typically take a daily dose of 15 mg of Adderall XR. While I do consume caffeine, it’s mostly in the form of one or two cans of Coke Zero each day; I’m not much of a coffee drinker, although I occasionally indulge. I prefer black tea or energy drinks, but those are consumed sparingly, just a few times each month. I reside along the Gulf Coast, known for its high heat and humidity, yet I experience these symptoms even during winter months. This situation also occurred when I lived in North Carolina. Although I have pets at home, these episodes happen more frequently when I am apart from them. My alcohol intake is minimal (just once or twice a month), but I’ve noticed that drinking red wine sometimes causes a tightening feeling in my nasal passages. I do not use tobacco products. I understand that a visit to my primary care physician would be the best course of action, likely starting with some allergy testing. However, I am curious if others have experienced similar symptoms linked to different conditions. I appreciate any insights you might have!
Is It Just a Cold or Something More Serious?
I'm a 24-year-old female, weighing 160 pounds, with a history of asthma for which I use a budesonide inhaler daily. Since Monday, I have been experiencing nasal congestion and a sore throat. The mucus I’ve been producing varied; it was frequently clear but occasionally appeared yellow. I did not have any coughing episodes. I monitored my temperature daily and did not register a fever at any point. Notably, I completely lost my ability to taste and smell. Initially, I tried taking DayQuil and Dimetapp, but those didn’t provide any relief. Eventually, I switched to my allergy medication, Zyrtec, which started to alleviate my symptoms by yesterday. I also took a rapid home COVID test, which yielded a negative result.
Transitioning Antibiotics: From Bactrim to Augmentin
Over the past week, I began experiencing symptoms reminiscent of a urinary tract infection. Seeking assistance, I visited Planned Parenthood yesterday. Although I won't receive my urine culture results for a few days, the healthcare provider prescribed Bactrim, as I was hesitant to delay treatment through the weekend. However, because I started the medication immediately, it's likely that the urine culture will be analyzed after I've completed the Bactrim course. They assured me that they would follow up with my test results to verify whether Bactrim effectively targets any potential bacteria. I felt a noticeable improvement, particularly after my first dose. Simultaneously, I also started to develop what seems like tonsillitis. The symptoms of my sore throat were quite similar to those of strep throat. Ideally, I would have gone to a clinic for an in-person test, but my current unemployment status and lack of insurance make me wary of incurring significant costs. While I considered letting the infection clear up on its own, I couldn’t shake the concern over the potential complications associated with strep throat. Therefore, I consulted with a provider at InstaCure, who recommended Augmentin after learning I was currently on Bactrim. I intended to use GoodRx for my prescription since it offers affordable options, especially at Safeway. However, prior to my appointment at InstaCure, the physician did not fully address my question regarding the safe transition from Bactrim to Augmentin. I tried to request a transfer for my prescription through Safeway’s website, only to learn that it could take up to three days to process. Now, I am uncertain about how to proceed while waiting to obtain my antibiotics. Is it advisable to cease taking Bactrim entirely? I’ve always been told to complete the entire course of antibiotics to avoid resistance, which adds to my concern. If anyone has any medical insights or advice on this matter, I would truly appreciate your help! Thank you!
19F — Is it time to discontinue this antibiotic? Unusual side effects, but UTI symptoms are improving
I was given an antibiotic for a suspected urinary tract infection (UTI) after ruling out sexually transmitted infections with negative test results. My physician also detected signs of a yeast infection, which led me to use a vaginal suppository earlier this week for treatment. The discomfort during urination has lessened, indicating that the antibiotic is effective. However, I have begun to notice: • Small, non-itchy bumps on my face that resemble light breakouts. • Possibly some mild difficulty in breathing (not pain in my chest, just a slight sensation of breathlessness at times). I am currently on my fifth dose of the antibiotic, with a total of fourteen doses required (500mg every twelve hours), and I'm becoming concerned that I might be experiencing a mild allergic reaction. I have yet to take my next dose because I'm uncertain about whether it is wise to proceed. Has anyone else dealt with similar situations? • Is it advisable to pause the medication at this point? • If I stop, could I resume it later, or would I need an alternative antibiotic? • Could these symptoms be related to hormonal changes since my menstrual cycle is approaching? I would greatly appreciate any insights or related experiences you could share. 🙏
30-Year-Old Seeking Advice on Cannabis-Induced Anaphylaxis: Exploring Possible Terpene Allergens
**Health Background:** - Experienced three anaphylactic reactions associated with marijuana over an eight-year timeframe. - The latest episode was triggered by a dosage of 5-7mg THC from a legally regulated and laboratory-tested product. - Each reaction necessitated emergency medical attention. - The pattern of response is erratic; in some instances, exposure resulted in no symptoms whatsoever. **Primary Inquiries:** 1. Does the medical literature recognize instances of cannabis-related anaphylaxis? Are there documented cases connected to specific: - Terpenes such as myrcene, limonene, or pinene? - Contaminants like mold or pesticides? - Other cannabinoids that do not contain THC? 2. In light of the unpredictable reactions, what should my strategy be: - Should I maintain access to an epinephrine auto-injector despite the sporadic nature of my symptoms? - Is there merit in pursuing targeted allergy testing? - Would it be prudent to completely abstain from all cannabis products? 3. Might my condition suggest mast cell activation syndrome rather than a classic IgE-mediated reaction? **Further Details:** - Anaphylactic reactions have occurred with various cannabis product formats, including both flower and edibles. - There are no other allergies to medications noted in my history. - I appreciate the therapeutic effects when they can be tolerated, but my safety is paramount. I am particularly eager to hear from experts in allergy and immunology regarding: - Recommended diagnostic approaches. - Suggested management strategies. - Any relevant published case studies on this topic. 1. **Is this a recognized yet seldom-encountered allergy?** Could it stem from a particular terpene, a contaminant, or something entirely different—in addition to THC? 2. **Is it advisable to always have an EpiPen on hand?** Opinions among medical professionals have varied because of the unpredictable nature of my reactions. 3. **Has anyone dealt with similar issues?** If so, were you able to pinpoint any triggers or establish effective precautions? I would greatly value any medical advice, shared experiences, or guidance on navigating this challenging situation.
