Should I Combine a Laxative with Moviprep for My Colonoscopy Preparation?
Hello all! I'm set to undergo a colonoscopy tomorrow afternoon due to some rectal bleeding I’ve experienced. Right now, I’m at the stage of having just completed my first liter of Moviprep this evening (it's 6:30 PM here in the UK). Earlier today, I woke up with a terrible migraine, and in my disoriented state, I ended up taking an over-the-counter pain reliever—two tablets of cocodemol, each containing 8 mg of codeine. This was around 9:30 AM. Although I generally manage my migraines with paracetamol and ibuprofen, I was concerned about their effectiveness, especially with my stomach being empty later on today. Just to clarify, I don’t typically use cocodemol. Since the hospital is currently closed, I’m following the instructions to start Moviprep as planned. I’m contemplating whether it would be wise to take an additional laxative from the store to balance out the effects of the cocodemol. I’m feeling quite anxious about the upcoming procedure and am regretting my earlier decision. Thanks for your help! 😊

It's understandable to feel anxious about your colonoscopy preparation, especially after experiencing a migraine and taking cocodemol. Here’s what you need to know:
Main Points:
- Avoid additional laxatives: Taking an extra laxative alongside Moviprep is not recommended.
- Focus on hydration: Continue to stay hydrated to help with the Moviprep and your overall comfort.
- Monitor your symptoms: Keep track of how you feel as the procedure time approaches.
Explanation:
Moviprep is specifically designed to prepare your bowels for a colonoscopy by causing your bowels to empty. Adding another laxative could lead to excessive bowel activity, cramping, or discomfort, which you want to avoid right before your procedure. The cocodemol you took can cause constipation as a side effect, but the Moviprep is intended to counteract that, so additional laxatives aren't necessary or advisable.
Next Steps:
- Continue Moviprep as directed: Finish the Moviprep as per the instructions provided to you. Make sure to drink plenty of clear fluids alongside it to stay hydrated.
- Stay calm: Find ways to manage your anxiety, like deep breathing or listening to calming music. Remember that medical staff is experienced in managing scenarios like yours.
- Observe for symptoms: If you have any unusual symptoms, like severe abdominal pain, prolonged nausea, or changes in your bowel movements that feel concerning, pay attention to those.
You’re doing the right thing by preparing for your colonoscopy carefully. If anything feels off, don’t hesitate to reach out to the medical team when they are available. Good luck with your procedure! 😊

Assessing Facial Swelling: When to Seek Help
I am a 36-year-old woman, standing at 5'6" and currently weighing 135 pounds. Just yesterday, I underwent an extraction of my upper right back molar, which shattered during the procedure (my dentist may have referred to it as tooth number 1). I'm currently prescribed clindamycin three times daily to combat an infection, along with Norco 5 as needed for pain management. I have a follow-up appointment scheduled for tomorrow to evaluate my healing process. However, I'm concerned about the swelling in my face. Should I head to the emergency room, or is it possible for my dentist to fit me in for a visit this afternoon?
Could This Be Ringworm?
For over a month now, I've had a rash on my left thumb, specifically the F32 area. I first observed it when it was roughly the diameter of a pencil eraser. Interestingly, I just resumed taking Zoloft and Wellbutrin about a week ago; however, the rash had already made its appearance prior to starting these medications.
Should I Visit the ER or Urgent Care for Blood in My Stool?
I’m a 27-year-old man currently taking finasteride (1 mg) and amoxicillin (500 mg). Recently, I’ve noticed intermittent occurrences of maroon blood in my stool, which have become more frequent over the last couple of weeks. Additionally, I’ve been feeling a burning or stinging pain in my lower left abdomen that fluctuates, registering around 4 to 5 on a discomfort scale. Just yesterday and again today, my stools exhibited dark maroon streaks. I have a gastroenterologist appointment scheduled for Monday, but I’m wondering if I should seek immediate care at the ER or an urgent care facility before then. I’m uncertain whether it’s safe to hold off until my appointment or if I should get evaluated sooner. I appreciate any guidance you can offer. Thank you!
Concerns Regarding Surgical Site Appearance
Are there any surgeons among us? I’m a 36-year-old man, measuring 5 feet 5 inches tall and weighing 125 pounds. I underwent ulnar nerve release surgery at my wrist on July 18th and attended a follow-up appointment with my surgeon's physician assistant (PA) yesterday, August 5th. During the visit, the PA informed me that everything appeared to be healing well and that I had no limitations. However, the following day, I noticed that the incision seems excessively open, even though there’s no bleeding or discharge present. What concerns me is the presence of some white material in the center of the incision. Should I reach out to my doctor just a day after my appointment, or is this appearance typical during the healing process? I wonder if the open area at the top of the incision will eventually close as recovery continues. The PA applied steri-strips, which I am to wear for another week before commencing physical therapy, where I will massage the incision to minimize scar tissue, and I have been diligent about keeping them on. I would appreciate any insights! Thanks!
Elevated White Blood Cell Count and Neutrophils Following Surgery
A 35-year-old female patient presents with a notable history of prolonged menstrual cycles, experiencing periods that can last over 20 days with only brief intermissions of up to five days in the last three years. Despite numerous diagnostic evaluations, including uterine biopsies, ultrasounds, hysteroscopy, and D&C pathology reports, all results have returned normal. After two years of low ferritin levels, she developed hypothyroidism, which is currently managed effectively with levothyroxine. Her heavy menstrual flow led to significant anemia, indicated by a low hemoglobin level of 5 and a ferritin level of 3. In April 2025, her treatment involved two blood transfusions and two iron infusions. Subsequently, at the end of May 2025, she underwent a hysterectomy coupled with a bilateral salpingectomy. The surgical procedure was successful, and her recovery has proceeded without complications. However, since the surgery, her white blood cell count (WBC) remains elevated at 12.1 (reference range: 3.8–10.8 thousand/uL), along with elevated absolute neutrophils at 8204 (reference range: 1500–7800 cells/uL). Additionally, her red blood cell count (RBC) is somewhat high at 5.14 (reference range: 3.8–5.10 million/uL), while mean corpuscular hemoglobin (MCH) is slightly below normal at 26.1 (reference range: 27–33 pg). All other components of the complete blood count (CBC) fall within normal limits. While her primary care physician has expressed concern about these findings, they remain uncertain and have referred her back to her hematologist, who also lacks explanations. What tests should she consider requesting? Or is there a necessity for further investigation into this matter?
