Is This Vitamin D Dosage Safe?
Recently, I underwent blood tests, and my vitamin D levels were measured at a mere 14 nmol/L. As a response, I was instructed to take a hefty dose of 20,000 IU of vitamin D each day for a duration of 15 days, labeled as a "loading dose." Following that period, I was to switch to a standard vitamin D daily supplement. Feeling uncertain about this substantial amount, I consulted my general practitioner for reassurance, who confirmed that this dosage was acceptable, with a pharmacist echoing the same sentiment. However, I've now received instructions to discontinue the over-the-counter vitamin D and am being referred for additional blood tests to check for hypercalcemia. An internal note has been made stating that "Fultium was recommended on a daily basis instead of weekly, with toxbase verified," which raises my concern that they might have made an incorrect prescription despite my inquiries for clarification. For context, I am a 22-year-old female, weighing 109 kg and measuring 177 cm tall. My doctor was assessing me for various symptoms, including episodes of numbness, fatigue, visual impairment, speech difficulties, insomnia, migraines, swallowing issues, memory lapses, and mood swings. My aim was to obtain a referral to a neurologist since both of my relatives have been diagnosed with multiple sclerosis. However, I was informed that I must achieve a normal vitamin D level first to be considered for the referral. Although I am unsure if vitamin D deficiency could be linked to my symptoms, it seems plausible since that has been indicated by the doctors.

It sounds like you have significant concerns regarding your vitamin D levels and their potential relation to your health symptoms. Here, let’s break down the main points and provide actionable steps to address your situation.
Main Points:
- Your diagnosed vitamin D deficiency (14 nmol/L) is being treated with a high initial dose (20,000 IU) followed by daily supplementation.
- You are also experiencing symptoms that may require further neurological evaluation, linked possibly to your vitamin D status.
- Current instructions advise discontinuing over-the-counter vitamin D while awaiting further testing for hypercalcemia, which should be monitored.
Explanation:
Vitamin D plays a crucial role in various bodily functions, including bone health, immune response, and possibly neurological health. The loading dose prescribed by your doctor is a common approach to quickly raise very low levels, and while 20,000 IU/day may sound high, it is generally safe for short periods under medical supervision, especially for addressing severe deficiencies. Your doctors likely are monitoring your progress and any potential side effects, such as hypercalcemia (high calcium levels), which can occur if too much vitamin D is taken.
The need to normalize your vitamin D levels before considering a referral to a neurologist might stem from the idea that symptoms like fatigue and cognitive changes could improve with adequate vitamin D.
Next Steps:
-
Follow Medical Advice: Continue taking the prescribed vitamin D supplement as directed (20,000 IU for 15 days), and comply with the recommendation to stop additional over-the-counter vitamin D.
-
Monitor Symptoms: Keep a detailed diary of your symptoms, noting any changes (improvement or worsening) over the next couple of weeks. This can help your healthcare providers in assessing progress.
-
Stay Hydrated: Ensure you are adequately hydrated and maintain a balanced diet to support your overall health during this period.
-
Schedule Follow-Up Tests: Ensure that you complete the follow-up blood tests as recommended to monitor your vitamin D levels and check for hypercalcemia. Keep your healthcare provider informed of any new or worsening symptoms.
-
Gather Information: If you still feel uncertain about your treatment plan or the rationale for denying the neurologist referral, consider asking your doctor or pharmacist clarifying questions about what was discussed and what the next steps should entail.
-
Consider Emotional Support: Experiencing multiple symptoms, especially regarding neurological health, can be stressful. It may be helpful to talk to someone about your feelings, whether it’s a friend, family member, or a mental health professional.
By focusing on these steps and keeping an open line of communication with your care team, you can navigate this process with greater clarity and support. If you have further concerns or need more assistance as you move forward, don’t hesitate to reach out for help.

Navigating Alcohol Consumption While on Antidepressants
I am currently prescribed Escitalopram at a dosage of 10mg and Trazodone 50mg, which I take before bed for my mental health. Additionally, I use Clonazepam to help manage my anxiety. Earlier today, I joined a few friends for a social gathering where we had some drinks. I informed them that due to my medication, I usually avoid alcohol; however, I opted to have a single beer so I could participate in the festivities without feeling out of place. Now, approximately three hours later, I do not sense any lingering effects of alcohol. If there were any, they are quite subtle. My question is: Is it safe for me to take my medications in light of this?
Concerns About Potential Brain Damage at 16
To begin, I’d like to clarify that I’m currently located in Europe, where I observe that many individuals in my environment engage in more extreme behaviors than I do, even as I strive to partake in social activities without crossing the line into recklessness. My journey with alcohol commenced at the age of 14, albeit in a very mild manner. By the time I turned 15, I started drinking more regularly, making sure to space out my experiences approximately weekly to monthly, totaling around ten instances of intoxication. Notably, I noticed I had an adverse physical reaction to alcohol—specifically, skin flush the following day—which prompted me to transition to cannabis as it felt easier on my body. I limited my cannabis use to weekends while adhering to similar spacing, with one exception. At 16, I found myself smoking almost every day for a week after a particular incident, but I was able to regain control thereafter. When I was 15, I also experimented with psilocybin mushrooms on two occasions, which proved to be positive experiences and made me realize I needed to cut back on alcohol consumption. Recently, I had a successful experience with 150 micrograms of LSD after careful preparation. This evening, I intend to consume half an edible instead of resorting to drinking or smoking, aiming to increase my intervals between substances to once a month at a minimum while maintaining a healthy lifestyle as an athlete. Despite my efforts, my naturally anxious disposition makes me concerned about anything that may cause irreversible damage to my brain, including, for instance, excessive screen time. I would greatly value insights from professionals regarding these worries. For context: I’m 16 years old, assigned female at birth but have been on testosterone for seven months, standing at 5'4" and weighing 125 pounds.
Concerns about HSV Transmission During Nasal Suctioning for My Baby
Recently, I experienced my first cold sore at the age of 29, appearing at the edge of my lower lip. With a three-month-old infant, I have been particularly cautious, believing that the herpes simplex virus (HSV) is transmitted solely through direct contact. I made sure to avoid kissing my baby and kept my distance. On her three-month birthday, she woke in the early morning with significant nasal congestion. Feeling exhausted, I instinctively reached for the Frida nasal suction, my usual go-to in such situations. While using the device, I made sure my cold sore was not in contact with it. Typically, I only use the suction in her nostrils, afterward blowing air onto my hand to check for any mucus and then continuing the process. However, as I performed this task, I began to question whether I was potentially spreading the virus; my research revealed that HSV can indeed be transmitted through saliva. Although most of my usage was suctioning, I realized I had occasionally blown into the tube to assess its effectiveness before resuming suction. Naturally, I'm feeling anxious and regretful for not thoroughly considering the risks involved. Additionally, I learned that my illness may have contributed to my cold sore, and now I suspect my baby may also be coming down with something—her first cold has me quite worried. I took precautions by wearing a mask, and throughout the week, she seemed unaffected. Being a breastfeeding mother, I hope she has received ample antibodies to help her. I would greatly appreciate any insights on whether I need to be alarmed or if there are specific signs I should monitor. Thank you for your assistance!
Dismissed as a Patient After 26 Years
For the past 26 years, I’ve been a patient at the same medical office, practically since the moment I entered this world (or rather, since I began my existence). Admittedly, I did transition from a pediatrician to a general practitioner when I turned 18, but I’ve mainly seen the same doctors throughout my life, including a general physician and a sports medicine specialist. During this extensive period, I have only missed a couple of appointments—perhaps just two in total—which seems quite reasonable considering I’ve had numerous check-ups and consultations due to various health issues, largely stemming from accidents and injuries. It’s not uncommon for someone like me, who tends to be accident-prone, to have over a hundred visits in nearly three decades. However, I recently discovered that I’ve reportedly missed three appointments in the span of six months. This unexpected revelation is frustrating, as those missed appointments occurred while I was recovering from orthopedic surgery following a significant work-related accident—I tumbled two stories off a ladder, highlighting my tendency for mishaps. The appointments I failed to attend were routine check-ups with my general practitioner, my sports medicine doctor, and a blood test. Unfortunately, they all coincidentally fell around the same period just after my surgery. I learned about the need for the surgery only a few weeks ahead of these scheduled appointments, and post-surgery, mobility was a challenge. I had asked my husband to cancel them on my behalf, but he neglected to do so—an oversight we share. While I take some responsibility for not ensuring the calls were made, I was heavily medicated with prescribed pain relief at the time. Despite my generally good attendance record, this series of missed appointments led to my dismissal as a patient. Today, when I contacted the office to request a refill for a chronic medication unrelated to the surgery, I was informed that I can no longer receive care there, as I was discharged as a patient back in early January. This came as a shock, especially since they had filled a different prescription for me just weeks ago without any issues. It raises the question: how can they discharge me and then assist with a prescription shortly before? I’ve been on the same medication for over seven years, and I am not asking for anything out of the ordinary. If they want to sever ties after 26 years, I’m willing to find another provider, but it feels absurd to deny me vital medication after such a long-standing relationship. Is this a common practice? When I explained my situation—politely and respectfully—the response was still a firm refusal to refill my prescription. My discussions were limited to administrative personnel, leaving me at a loss about my next steps. I’ve always been a reliable patient, with the exception of these recent three appointments occurring immediately after the surgery. The urgency of my medical needs can’t be understated: I am in need of key prescriptions and follow-up care due to significant health concerns from my recent injury, numerous corticosteroid injections, and a positive result from a cancer screening test. Although statistics suggest the probability of a false positive at my age, it still necessitates thorough follow-up, especially given my family's history of this condition. For the past week, I’ve reached out daily, always with courtesy, yet I’ve received no resolution, just the run-around among various office staff. They mentioned they sent me a letter to inform me of my dismissal, yet I never received a call, email, or any subsequent communication. One single letter does not suffice to terminate a patient’s long-term relationship with their medical practice, especially when it involves critical prescriptions and post-surgery care. Is this standard protocol? I cannot stress enough that I am not embellishing my situation. With an almost flawless attendance record and a recent misstep due to surgical recovery, being abruptly cut off feels excessive. I truly appreciate my general practitioner, need my medication, and face a myriad of concerns—from continuity of care to other pressing health issues—which makes this entire experience deeply troubling and perplexing.
Uncertainty Surrounding My Health Incident
I am a 15-year-old girl currently battling a cold, and I also have a confirmed diagnosis of Ehlers-Danlos syndrome. Additionally, I suspect I may have POTS, although that's not officially confirmed. Earlier today, I got up to visit the bathroom, which requires navigating around twenty steps from the living room. As I stood up, I noticed my vision starting to blur, but that’s a familiar sensation for me, so I didn’t think anything was amiss. Upon reaching the bathroom, my eyesight faded to complete darkness. Losing my sight entirely isn’t unusual for me, and while frustrating, I merely found it bothersome rather than alarming. Once inside, I turned on the light, and although I couldn’t see it illuminating the room, I heard the click of the switch, indicating it was on. I then attempted to locate the sliding door to close it. However, I misjudged the doorway completely on my first try. I felt it was odd, yet I dismissed it and tried again, but I encountered the same issue. After my second attempt, I experienced significant trembling in my limbs, so intense that I realized I was on the verge of falling. To prevent that, I quickly lowered myself to the floor, remaining blind to my surroundings. After about five seconds, my vision began to return, and I noticed my legs were still shaking. A few seconds later, the shaking subsided, and I regained control over my body. I stood up right after, feeling relatively assured that it wouldn’t happen again, but I opted to sit for safety's sake. This event occurred just a couple of hours ago, and thankfully, it hasn't recurred. Although my vision tends to dim when I stand, that is a typical occurrence for me, and I’ve since retained partial sight. I did not lose consciousness during the incident and have clear memories of the entire experience, without confusion or disorientation afterward. Notably, epilepsy runs in my family; my aunt has it, and my mother’s cousin experienced several seizures a few months back, although he hasn’t had any recently. Personally, I have never fainted, though I’ve come close multiple times. It’s important to mention that I’ve never experienced a seizure before, and I remain uncertain whether what transpired was a seizure or something different altogether.
