  • Is it safe to take demerol while taking tramadol hydrochloride and hydroxychloroquine (2 answers)
    I am experiencing acute, debilitating pain due to the Chikungunya virus, which has reintroduced all of the previous painful symptoms I have,ongoing and in the past, from Fibromyalgia, Arthritis, tendonitis and severe headaches. It's in its 38th day and I am basically crippled from neck to feet. Have to sleep propped up as arms throb with pain when horizontal. The only thing that has subdued the pain slightly are Oxycocet and Ibuprofen, but the pain never goes away. My hands and feet are so inflammed it's difficult to perform even the smallest tasks of personal hygiene and housekeeping. I have difficulty controlling my bladder and often don't make it to the washroom in time. Just started on Demerol today so will no longer take the Oxycocet, but am concerned of the interactions with Demerol, Hydroxychloroquine and Tramadol Hydrochloride extended release tablets that I take daily for the Fibromyalgia and Arthritis. I have dealt with a great deal of pain through the years, but I now have the pain of every serious illness I have had in my lifetime, all at the same time. I honestly didn't think a person could deal with this much pain at once. I have tried and am still taking several vitamins and herbal supplements as well as drinking tons of water and eating really well. Lots of berries, dark vegetables, apples, yogurt and minimal meat. Taking turmeric, papaya leaf, ginger, cinnamon and boswellia for the inflammation. Taking minimal wheat products, sugar and no alcohol. Also, drinking green, fennel and nettle tea daily. I know this is a lot of information, but I really need help and wonder if anyone has any suggestions! Thanking you in advance!!!
  • What is the highest dose of demerol i can take at once and still be safe?
    I had major reconstructive back surgery
    With 2 titanium replaced vertebrae
    Fusion and pins holding 2 broken facet joints
    Together. I have post surgical herniation in
    Remaining vertebrae and post surgical nerve damage
    Radiating down both legs. Since Vicodin 750/750 has been taken off the market
    Nothing is helping me. My pain mgmt doctor is trying
    To help, but that means trying something new at a relatively low dose for a month then
    Reassessing. Which means I'm miserable for a month at a time if it's not working
    I'm almost out of options because nothing seems to be helping
    Years ago I had luck with Demerol injections in the hospital so I agreed to try Demerol pills now I'm stuck again with something that's not working. So my question is how many MHD of Demerol can I take at one time and still be safe. I have to survive until my next pain management appt June 4th
    And I'm in excrutiating pain. Any body know? Thank you
  • Can my his meds have causes bradycardia?
    I am 22 years old relatively healthy, and medium fit and i am his positive. I recently found out that i may have bradycardia as well... im trying to find out if my hiv meds have anything to do with it.
