Evaluating the Need for PEP After Recent Sexual Encounter
As a male who recently engaged in unprotected sex with a female acquaintance, I find myself reflecting on the risks involved. I had met this woman about a year ago, during which we exclusively used protection. She had undergone STD testing prior to our previous interactions and was confirmed to be disease-free. After some intermittent communication, we hadn’t met in over seven months. Last month, we rekindled our connection and I asked if she had been with anyone else in the meantime. She mentioned having a one-night stand in May, which she assured me was also protected. Although we’re not in a committed relationship, I requested that she get tested again before our next encounter. On July 7, she underwent testing, and all results, including the fourth generation HIV test, returned negative. We mutually agreed to engage in unprotected sex, given our clean bills of health. The day prior to our encounter, I inquired once more about the timing of her one-night stand, specifically if it had occurred after May 22, ensuring it was outside the 45-day window since her last test. She confidently affirmed that it had not. We proceeded to have unprotected sex last night. It has now been about 12 hours since that experience. Given that she has had a hysterectomy, concerns about pregnancy are alleviated. After our encounter, while expressing my trust in her, I also conveyed my worries and encouraged her to be upfront about any recent interactions post-May 22. I assured her that honesty wouldn’t lead to any judgment from me. She maintained that she was certain no such encounters had occurred. In my anxiety, I reached out to a telehealth professional who promptly prescribed post-exposure prophylaxis (PEP), and I began treatment about 20 hours after the sexual act. Now I’m left wondering: is starting PEP really necessary? Am I being overly cautious? This was my first experience with unprotected sex in many years, and my nerves are heightened. Although I have taken only a single dose of PEP thus far, I am contemplating whether it is essential to continue the regimen.

It's understandable to feel anxious after engaging in unprotected sex, especially given your concerns about sexually transmitted infections (STIs). Starting post-exposure prophylaxis (PEP) can be a reasonable precaution, but let's break down your situation to help clarify whether you should continue the treatment.
Main Points:
-
Your Risk Assessment: While your partner recently tested negative for STIs, you did have a brief gap where her sexual history was uncertain. PEP is usually recommended when there's a risk of HIV exposure, primarily when a partner's HIV status is unknown or if they are at high risk for being HIV positive.
-
PEP Recommendations: PEP is most effective when started within 72 hours after possible exposure and is taken for 28 days. Starting PEP about 20 hours after exposure is a good timing to potentially reduce your risk.
Explanation:
- HIV Risk: Since your partner confirmed she wasn't involved with anyone after her last test within the 45-day window preceding your encounter, this does reduce your risk, but it doesn't eliminate it entirely. Trust plays a role, but there is always uncertainty when it comes to sexual health, particularly regarding past encounters that may not be fully disclosed.
- PEP is Preventive: It doesn’t hurt to take PEP if the exposure was concerning. The anxiety surrounding the situation can be mitigated by knowing that you are taking steps to protect your health.
Next Steps:
-
Continue PEP: Since you’ve started the treatment and the timing is still appropriate, it’s essential to continue taking it as prescribed for the full 28 days. This maximizes its effectiveness.
-
Monitor Your Health: Be aware of any potential side effects from PEP, such as nausea or fatigue. Staying in touch with a healthcare provider during this period is important.
-
Follow-Up Testing: After completing the PEP course, follow up with an HIV test at the recommended intervals (usually at 4-6 weeks and again at 3 months) to confirm your status.
-
Address Anxiety: It’s perfectly normal to feel anxious after experiencing unprotected sex. Consider reaching out to a mental health professional if these feelings become overwhelming. They can offer strategies to help manage your anxiety.
-
Discuss Future Safe Practices: Use this experience as a learning opportunity. Consider making a commitment to always use protection in future encounters, regardless of your partner's previous testing history.
Your well-being is paramount, and taking preventive measures now is wise. If you have further questions or concerns, don’t hesitate to reach out for more support.

Concerns About My Son’s Sweating and Breathlessness During Exercise
Hello everyone, I am reaching out for some insights regarding my eight-year-old son. He is quite slender and remains very active, participating in various activities such as swimming, ice skating, and weekly boxing sessions, in addition to simply playing outside and running around our home. Recently, I’ve observed that he tends to become breathless and sweats more profusely than his classmates. For instance, during football, which is more focused on fun than competition, he often ends up soaked in sweat after only a few sprints and needs to pause for breath. Just the other day in boxing, he was the first kid to struggle with fatigue during a jogging session, surprising even the coach, who remarked, "Are you already tired?!" Interestingly, there were several heavier children who managed to keep going without experiencing the same level of perspiration. I have consulted with multiple medical professionals about this issue. He has been prescribed an inhaler because he occasionally experiences severe coughing after physical activity, though he has not been diagnosed with asthma. A recent blood test indicated a slight deficiency in Vitamin A, but no other abnormalities were found. Moreover, he seems susceptible to chest infections and tends to have a prolonged recovery when flu seasons hit. I can’t think of anything else at this time, but I would greatly appreciate any advice on what potential issues could be at play or how I might encourage my doctors to further investigate his symptoms.
Unexpected Experience with Pelvic Discomfort
At 20 years old, I recently encountered a perplexing situation related to my menstrual health. To provide some background, I previously used the Evra patch for contraception, which effectively suppressed my periods. After some time, I decided to pause its use to allow my body to reset. My last menstrual cycle occurred in April, after which I opted to resume using the patch continuously without waiting for my next cycle. However, as May progressed, I noted a delay in my period and decided to apply the patch while still awaiting its arrival. In the month following, I began to experience persistent pelvic discomfort and cramps, which I initially dismissed. Over the past few weeks, I noticed some light spotting and ultimately decided to let my body go through a menstrual cycle, sensing that it was overdue for one. Yesterday marked the commencement of my period; it involved significant pain accompanied by very light bleeding, primarily composed of older blood. But today, the pain escalated to an intensity I had never felt before. The pelvic cramps, combined with severe back pain, came in waves reminiscent of labor contractions. I felt nauseous and nearly fainted, and unfortunately, pain relief medications provided no assistance. Throughout the day, bleeding remained minimal. Just some minutes ago, I visited the bathroom. Upon sitting down, an unexpected object expelled from my body. To my surprise, it appeared as a thick, folded strip. My initial reaction was to assume it was a tampon, but considering the last time I used one was back in April, this seemed implausible. After its expulsion, I noticed a significant reduction in my pain; the unbearable waves ceased, leaving me with only minor cramps and a sensation of bloating. The size and shape of what came out were notably similar to that of two tampons; however, it wasn’t blood but rather a clear substance. This entire episode has left me feeling rather frightened and uncertain about what has occurred. While I do not intend to seek immediate medical attention, I’m left contemplating the implications of this experience and what steps I should consider next.
Experiencing Low Blood Pressure After Adjusting Lexapro Dose?
Hello everyone! Due to some intense panic attack episodes, I recently modified my Lexapro dosage. I moved from 10 mg to 15 mg for a brief period of 2 weeks, and now I’ve escalated it further from 15 mg to 20 mg for the last week. However, I've noticed that when I rise to stand or even bend down, my vision tends to fade and I often feel lightheaded 😭. This sensation has made me quite anxious, and as a result, I've avoided doing regular household tasks and have mostly been resting. I have been monitoring my blood pressure and found that it's hovering around 90/60. I’m a 25-year-old female weighing 230 lbs. I recall experiencing something similar when I began taking Lexapro, and I believe it subsided once my system adjusted to the medication. However, I'm not entirely certain if the Lexapro was the sole factor, as I was also about 100 lbs heavier back at that time. So, my main question is: Could altering the dose of Lexapro result in a temporary drop in blood pressure until my body acclimates to the new dosage?
Concerns Regarding Prostate Health After Catheterization
I’m a 37-year-old male with a weight of 180 pounds and currently, I’m not taking any medications. Earlier this year, in May, I faced a significant issue when a kidney stone larger than 7mm got lodged in a urethral stricture that had previously been treated through surgery back in 2018. Due to the stone's position, I required catheterization after an emergency cystoscopy failed to retrieve it; the catheter ended up being in place for over a month. Throughout this duration, I experienced intense irritation in my bladder and prostate, which intensified when I caught a cough that lasted a week. The catheter was taken out in June, and shortly afterward, I began to pass various stones and debris from my bladder— the larger stone was expelled in the hospital with the assistance of IV fluids and morphine. My primary worry is that I might have had a nocturnal emission while the catheter was still inserted. I noticed that the first thing I expelled was a white substance. My urologist suggested that this could have been white blood cells due to the inflammation present. For context, I’ve undergone four tests for bacterial urinary tract infections at three different labs, all resulting in negative findings, although my white blood cell levels were elevated. After the catheter was removed, I received diagnoses of prostatitis and cystitis. Now, on to my pressing issue: as the inflammation in my prostate has subsided, I've been feeling a strong urge for ejaculation. However, I am apprehensive that there could be old, hardened semen or debris that could be clogging the ducts connected to the urethra since the catheterization. I fear that any attempts to "clear my system" might lead to an excess buildup of semen within my prostate that can't be expelled, potentially causing further damage. I would greatly appreciate insight from medical professionals familiar with male reproductive and urinary systems on whether these concerns are valid.
Why Did Fexofenadine Trigger Disturbing Experiences for Me?
F23 It feels like I’m experiencing some sort of flare-up, possibly related to MCAS. My physical condition is currently in disarray, and I’m uncertain about the reasons behind it—though I’ll save that complicated tale for another time, as I doubt anyone would want to delve into that without compensation! Three days ago, I started taking Alevia tablets, 120mg, in hopes of finding some relief. On the first day, I took the medication and was completely knocked out. It was like nothing I’d ever experienced, not even with amitriptyline. I can’t recall any part of that sleep. For the past two nights, I've been plagued with incredibly vivid and disturbing nightmares that have taken a toll on my mental well-being. In one instance, I was pursued by a UFO with a man inside—just an ordinary guy? Additionally, I’ve been acting out of character, feeling inexplicably aggressive and entertained dark thoughts that are not typical for me. Is this reaction common? Has anyone else experienced similar symptoms? Regardless, everything feels off, and I sincerely hope that my general practitioner can provide guidance when I finally secure an appointment. Thanks!
