How Darvocet A500 Affects Patients

Acetaminophen is a drug used to reduce fever and pain. It does not cause inflammation, nor does it interfere with how the body produces uric acid or affects acid-base balance when taken in the recommended doses. It is also unlikely to cause allergic reactions. It does not interfere with blood clotting or prevent platelets from clumping together.

How Darvocet A500 works in the body

Acetaminophen works to reduce pain by blocking the body's ability to create pain-causing chemicals. It does this by inhibiting two types of proteins called cyclooxygenases, which are involved in the production of prostaglandins. Acetaminophen does not affect these proteins in other parts of the body, so it does not have anti-inflammatory effects. It is also thought to work on heat regulating centers in the brain, which helps the body to cool down and lose excess body heat. While we don't fully understand how acetaminophen works, more research may help us better understand its mechanism of action.

Darvocet A500 for Pain

I had shoulder surgery and took a drug containing codine that made me really sick. This drug has no side affect and works, but you need to use it every four hours or pain returns and it takes awhile to cut the pain again.

Darvocet A500 for Pain

I almost never take anything stronger than Tylenol because I'm worried about the side effects, but this weekend my back pain was so bad that I decided to give it a try. It worked really well with hardly any noticeable side effects (just a little drowsiness).

Darvocet A500 for Pain

I've been on Darvocet for a while now and haven't experienced any constipation. If you're struggling with this issue, I recommend trying a couple tablespoons of ground flaxseed with breakfast and drinking a few glasses of water each day. It helped me a lot!

The Vicodin didn't help much with my pain, and it made my anxiety levels spike. The Darvocet was a marked improvement in that it helped with the pain while also keeping me calm. I recommend this for anyone struggling with both pain and anxiety.

Darvocet A500 for Pain

I generally have had good results with this medication, so long as I stick to the white pills and not the pink generic ones. However, since I started taking B12 vitamins (1500mg), I've been getting headaches constantly and feeling lightheaded sometimes. Not sure what's going on there.

Darvocet A500 for Pain

I tried Darvocet instead of Vicodin because I was experiencing extreme nausea. Unfortunately, this led to serious mental side effects that forced me to discontinue use. When I went back to half doses of Vicodin, the results were much better. Overall, I would not recommend using this drug.

Guided Imagery Therapy for Abdominal Pain

7 - 12
All Sexes
Austin, TX

Chronic abdominal pain is common among children, and the majority of cases are attributed to functional abdominal pain disorders. One approach to treating these disorders is by using psychological therapies. This clinical trial aims to see how well pre-recorded guided imagery therapy sessions help children's abdominal pain when delivered via a mobile application (app) on a smartphone or tablet. Participants will complete a baseline abdominal pain and stooling diary to determine eligibility, as well as other surveys. Eligible participants will be given access to the guided imagery therapy mobile application. This intervention asks participants to listen to a 10- to 15-minute GIT session 5 out of 7 days per week for 8 weeks, in addition to their usual care for their abdominal pain. Then, participants will complete another abdominal pain and stooling diary, along with other psychometric surveys, at the end of this intervention period. Participants will also collect another diary and surveys 3 months post-treatment.

Erector Spinae Plane Block for Pain

21 - 75
All Sexes
Cleveland, OH

As per usual care for spine surgery, participants will have their back cleaned with alcohol and a needle will be placed using ultrasound for the ESP block. Through the needle, a small catheter will be placed in the participants back and the needle removed. Approximately one hour prior to the start of surgery, a numbing medication (ropivacaine, similar to Novocaine) in combination with dexmedetomidine (a pain medicine that is used in nerve block and that is not a narcotic) and contrast dye (iohexol) will be injected through the catheter. Participants will then go through the QST procedure (test of buzzing sensation and temperature sensation through pads applied to their skin) to assess the numb areas and then head to the operating room. In the operating room, the catheter will be removed after the surgeon obtains baseline CT scan images of the spine. Once surgery is completed, investigators will record pain scores over the next four days in the hospital and the amount of pain medication needed for controlling pain related to the surgery.

Digital Media for Anxiety in Children

5 - 23
All Sexes
Vancouver, Canada

The goal of this clinical trial is to learn whether different forms of media (2D, 360, or 360 in virtual reality) have different impacts on pre-procedural anxiety and post-procedural pain in children. The main questions it aims to answer are: Does one type (and richness) of media reduce pre-procedural anxiety and post-procedural pain more than another type of media? For example, will learning about an upcoming procedure by watching a 360 video in virtual reality reduce pre-procedural anxiety more than learning about the same upcoming procedure by watching it in a 2D video or 360 video? The second question is whether watching a 360 video in VR about an upcoming procedure more effective in reducing pre-procedural anxiety and post-procedural pain compared to the 2D video or the 360 video without VR groups for specific procedures? For example, is watching an explanation of a procedure in VR always more effective in reducing pre-procedural anxiety and post-procedural pain, or is it procedure specific (i.e., watching a video about surgery preparation is more effective in VR, but for cast removal it doesn't matter whether participants learn about their procedure viewed through VR, 360 video, or 2D)?

Choose to Move Replacement Ready for Osteoarthritis

18+
All Sexes
Vancouver, Canada

Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. Recently, the investigators adapted CTM for the \>14000 people in BC who are on surgical waitlists for total knee replacement or total hip replacement (TKR/THR) for osteoarthritis (OA). The primary goal of this observational study is to learn if the adapted program, Choose to Move Replacement Ready (CTM-RR), is feasible to deliver to people with hip and/or knee osteoarthritis who are on surgical waitlists for TKR/THR. Participants who enrol in CTM-RR will answer online survey questions about the program and about their physical activity, mobility, pain, function, quality of life, willingness to undergo surgery, overall perception of their joint condition, psychosocial health, self-efficacy, social isolation, loneliness, and sedentary time. CTM-RR activity coaches will also answer online survey questions about the program. CTM-RR participants, activity coaches, and referral partners will also participate in interviews about the program.
