Concerns Regarding Midodrine and Blood Pressure Management
Hello there! I'm a 23-year-old female with a diagnosis of POTS and I'm currently not on any medication for it. My blood pressure tends to fluctuate quite a bit due to this condition. Just over a week ago, I visited a cardiologist where my readings were 104/70 while lying down, and after standing for 10 minutes, it increased to 122/102. Today, I saw a different cardiologist, and my blood pressure readings were as follows: - Supine (after 5 minutes): 118/76 - Sitting (after 5 minutes): 104/80 - Standing (after 5 minutes): 100/80 Based on these measurements, my new doctor has prescribed midodrine, which I haven't started taking yet. However, I have concerns about beginning this medication because my blood pressure can sometimes rise, particularly the diastolic reading. Is it safe for me to start this medication? Should I be worried about the potential for my blood pressure to rise significantly? Additionally, I've noticed that my blood pressure tends to increase after meals, which adds to my concerns.

It's understandable to have concerns about starting a new medication, especially with a condition like POTS. Midodrine is often prescribed for orthostatic hypotension in patients with this condition, but it does have specific effects on blood pressure that need consideration.
Main Points:
Midodrine can help manage low blood pressure associated with POTS but may raise blood pressure levels, particularly the diastolic reading. Close monitoring is important when starting this medication.
Explanation:
Midodrine works by constricting blood vessels, which can elevate blood pressure. In some patients, it helps stabilize fluctuations, but individual responses can vary. Your readings suggest that while you experience fluctuations, your blood pressure falls within a manageable range at times, especially supine and sitting. Concerns about significantly elevated diastolic pressure after starting midodrine are valid, given your history of fluctuating blood pressure.
Next Steps:
-
Start Gradually: If you decide to start midodrine, consider starting with the lowest dose recommended by your doctor and monitor your body’s response closely over the first few days.
-
Keep a Blood Pressure Log: Measure your blood pressure at the same times each day (lying down, sitting, and standing) to identify patterns. This can help you and your healthcare provider understand how midodrine affects you specifically.
-
Monitor Symptoms: Pay attention to how you feel. If you notice significant headaches, an increased heart rate, or feeling unwell with higher blood pressure readings, these may be signs to discuss with your doctor.
-
Meal Considerations: Since you’ve noted that your blood pressure increases after meals, maintain balanced meals and consider smaller portions to see if that helps manage those fluctuations.
-
Follow Up: Schedule a follow-up appointment with your doctor after starting midodrine (typically in 1-2 weeks) to review your blood pressure logs and any symptoms you’ve experienced. Adjustments to your medication may be needed based on how you respond.
It's essential to feel empowered in your treatment plan. Discuss any persistent concerns with your healthcare team to ensure they are aligned with your health goals. If you need further clarification, feel free to reach out.

Understanding Testosterone Levels Post-Orchiectomy
Greetings, I’m a 27-year-old male who underwent an orchiectomy approximately six months ago, as a result of testicular torsion that the emergency services failed to identify in a timely manner. I am seeking insight regarding how this procedure might affect my testosterone levels and overall fertility.
Understanding Levothyroxine Dosing for Hypothyroidism
**Age:** 29 **Gender:** Male **Height / Weight:** 5'9" and 85 kilograms **Current Medication:** Levothyroxine at 100 mcg daily **Duration of Condition:** Approximately 10 months **Location:** India **Anti TPO Level:** 140 I seek evidence-based insights regarding the appropriate dosage of levothyroxine in my case. ### Background: Around ten months ago, I was diagnosed with hypothyroidism; my TSH levels initially measured around 56. Following this, I began a treatment regimen with levothyroxine, starting at 50 mcg daily. After four to five months on this dose, my TSH levels dropped to roughly 18, though they remained elevated. Consulting with another physician, it was suggested that my body weight warranted a higher dosage of 100 mcg. Upon increasing my dosage to 100 mcg, my TSH levels improved significantly over the next two to three months, dropping to about 2.9, and I noticed a marked improvement in my overall well-being. Recently, I sought advice from a doctor in my hometown regarding the possibility of reducing my dosage from 100 mcg. His feedback included the following points: - He considered the 100 mcg dose excessive. - He stated that TSH dosing should not rely on body weight, which contradicted my understanding based on my own research. - He believed I should have commenced treatment at 25 mcg. - He prescribed L-Trosule (which contains L-tyrosine, iodine, magnesium, among other components) for one month while advising me to maintain my current 100 mcg dosage. - He recommended retesting TSH, T3, and T4 levels in one month. ### Inquiries: 1. Given my progression (TSH moving from 56 to 18 on 50 mcg, then to approximately 2.9 on 100 mcg), does the 100 mcg dosage seem aligned with my genuine replacement needs? 2. If any adjustments to my dosage are required, would it be more sensible to gradually taper down (for example, from 100 to 75 mcg) while monitoring lab results, rather than halting treatment or switching solely to supplements? 3. Is there any corroborated evidence supporting the use of supplements like L-Trosule for individuals with established hypothyroidism, particularly when there is a suspicion of autoimmune thyroid disease? 4. What would be considered the most prudent and safe approach for long-term management in my case? I welcome perspectives from medical professionals on whether it is advisable to stay at the current 100 mcg dosage, consider tapering, or explore a supplement-only approach in light of my situation.
Unpleasant Taste in Mouth
I am a 25-year-old female, measuring 5 feet in height and weighing 88 pounds. My medication regimen includes a gel antacid as well as a birth control pill. Over the past month, I've been experiencing an awful sour flavor in my mouth. It's not a daily occurrence, but it is happening frequently, and it appears to be intensifying. Along with this, my mouth has been feeling notably dry, and the taste has an unpleasant soapy quality to it. In fact, I was compelled to measure the pH of my saliva due to the severity of the situation. While I have a history of acid reflux, which I've managed without issues for the last decade, this strange taste is unlike anything I've encountered before. Interestingly, the problem seems to worsen throughout the day, with milder sensations upon waking. Additionally, I have concerns regarding the possibility of pregnancy. Although I'm diligent in taking my birth control, I've experienced unexpected breakthrough bleeding recently after being stable for many years. My physician mentioned that I might not be effectively absorbing the pill, despite there being no known reason for this change. Another layer of complexity has arisen with my breakthrough bleeding showing an unusual pattern; I faced occurrences when I typically wouldn't, and currently, I am not experiencing it at all, which is out of character for me.
Understanding Missed Pills with Slinda and Continuous Usage
I’m a 21-year-old woman, weighing 54 kg and standing 160 cm tall. Recently, I began taking the pill right after having my IUD taken out in January. Since I experience chronic migraines with aura, estrogen-based options are not suitable for me. If I choose to skip the four placebo pills and move directly to the next set of active pills, can I then take a four-day pause if I end up having some bleeding? My approach is to bypass the placebo pills entirely unless I encounter breakthrough bleeding. After taking the active pills for several months straight without any breaks or placebos, would it be acceptable to take a four-day hiatus (similar to a placebo phase) to induce a bleed before resuming the active pills once more?
Safety of Norethindrone for a 50-Year-Old Smoker Planning to Delay Menstruation
I have been prescribed a regimen of 5mg Norethindrone Acetate, taking three tablets daily, in order to postpone my menstrual cycle for an upcoming vacation. Given that I smoke a pack of cigarettes each day and am 50 years old, is it advisable to use this medication continuously for ten days? I’m feeling anxious about this decision. My gynecologist assured me it was safe, but the information I’ve found online tends to increase my worries.
