I am a 50-year-old woman, and recently, my physician prescribed promethazine DM for me. Initially, I believed the dosage instructions indicated that I should take between 6.5 and 15 ml every six hours. However, upon further review, I now see that it actually says to only take 5 ml. I’m feeling quite anxious right now after having taken 6.5 ml. Is this a cause for concern? Should I consider calling emergency services?

It's understandable to feel anxious after a dosing mistake, but let's assess the situation calmly. Taking 6.5 ml of promethazine DM when the recommended dose is 5 ml generally isn't a cause for emergency concern, especially since the dose is slightly above the recommended amount. However, it's important to monitor yourself for any unusual symptoms.

Explanation:

Promethazine is an antihistamine that can be used to treat allergy symptoms or motion sickness. While exceeding the dosage can potentially lead to side effects, the small increase you've mentioned is likely not dangerous for most people, but individual responses can vary based on factors like weight, overall health, and any other medications you may be taking.

Next Steps:

  1. Stay Calm: Take a few deep breaths to help reduce your anxiety.
  2. Monitor Symptoms: Keep an eye out for any signs of adverse effects such as extreme drowsiness, confusion, difficulty breathing, or any other unusual symptoms.
  3. Hydrate: Drink water to help your body process the medication.
  4. Avoid Additional Doses: Do not take any more promethazine until you’ve clarified the situation with your healthcare provider.
  5. Contact Your Doctor: If you do experience any concerning symptoms or feel uncertain, reach out to your doctor or a pharmacist for personalized advice rather than calling emergency services right away.

If you feel significantly worse or develop severe symptoms, then seeking immediate medical help would be essential. Monitoring yourself closely and staying in touch with healthcare professionals will provide you peace of mind. Let me know if you need more information or support!

Moment of Vision Loss Lasting Less Than a Second

Age: 24, Weight: 130 lbs, No current medications, Medical history includes mild cerebral palsy, lymphedema, pancreatic cysts, and an arachnoid cyst. This morning, while assisting my child with a bath, I exited the bathroom to quickly fetch my glasses, which I hadn’t worn earlier. After putting them on, I leaned down to help her get out of the tub. At that precise moment, my vision went completely dark for a split second; so abruptly that I initially thought there might have been a brief power interruption. I then checked various appliances around the house, including the stove, to confirm if there had been any flickering lights, but everything was functioning normally. It became clear to me that the issue was related to my eyesight rather than a power failure. The incident occurred so swiftly that I struggled to process that my vision had actually vanished. I believe I could still make out my child's silhouette in the bathtub during that moment, but retrospectively I’m uncertain as it was merely a fraction of a second. Previously, during my pregnancy a few years ago, I experienced low blood pressure, which led to similar brief vision loss on one or two occasions. In those instances, I also felt faint, as if I might faint. In contrast, this time I had no accompanying symptoms: no significant dizziness (though I was likely anxious about what just transpired), no headache, or visual disturbances. Could there be a reason behind this occurrence? Should I reach out to my primary care physician regarding this episode?

Concerns About Hygiene After an Unexpected Encounter

My boyfriend, who is currently studying medicine, suggested that we engage in intimacy while he was wearing his clinic white coat. Unfortunately, things got a bit messy, and bodily fluids ended up on the coat. It was definitely unpleasant! I assumed he would wash it before returning to the clinic. To my surprise, I discovered this morning that he had gone to the clinic wearing that same coat. Given that he had no time to launder it, I can’t help but feel a sense of disgust and worry. I’m anxious about whether this could pose any potential risks to his patients’ health. Just for context, he is a 25-year-old man, and we both practice good hygiene!

Numbness in Left Ring Finger Tip

Hello everyone, I'm a 24-year-old male, weighing approximately 87kg and standing 188cm tall (I noted some missing details in my previous post). Last night, I was jolted awake after around 30 minutes due to numbness in the tip of my left ring finger. Initially, the entire fingertip was affected, but as I slept and went through my day today, the numbness has shifted mostly to just the underside of the finger. At what point should I start to be concerned? While it’s primarily bothersome, I’m also experiencing what feels like nerve pain in my arm (or at least I think that's what it is). I've had prior issues with my ulnar nerve in my right arm, so I suspect it might be related.

Understanding the Need for Baseline X-Rays

Today, I had my yearly check-up with my family physician and I'm a Canadian male in my 50s. As part of the usual assessments, which included blood tests, an EEG, and a FIT test, my doctor recommended that I undergo a chest X-ray. He noted that my last one was performed back in 2018, and he believes it's important to have a current one for a reference point. I inquired if there were any specific issues during my examination that warranted the X-ray; he indicated that there weren’t any and confirmed that establishing a new baseline was the primary reason for the request. From our discussion, it appears that this won’t become a yearly requirement, especially given that during my last visit, he didn’t suggest one. It sounds more like it’s meant to be done every five years. While I am accustomed to routine blood tests and similar procedures, this is my first experience being advised to obtain an X-ray for baseline purposes. Is this something that is becoming more common in medical practice nowadays?
