While effort has been made to ensure that calculations are accurate and that conversion factors are in accordance with current accepted medical practices, use of this application is entirely at your own risk. This application should only be used by trained medical professionals and all results should be double checked by hand.

Pros and cons of Opioids Dosage Conversion app for iPhone and iPad

Opioids Dosage Conversion app good for

Good app! It would be nice to add one or two more drugs, like tramadol.
Exactly what I needed. While I have other converters, this one gives way more detail and cautions than the others
Better app than most. this app Needs more than just the select few opioids it currently has. Developers, please add these drugs... buprenorphine, meperidine, pentazocine, diacetylmorphine, tramadol. Additional benefit from: References or documents (or links) for current canadian, american, and british therapeutic guidelines for the management of acute, chronic, cancer, bone, and neuropathic pain. Added benefit would be guidelines for CRPS, rheum/osteo Arthritis, shingles and other types of pain.

Some bad moments

This is a simple to use conversion system. Sure, Id love to have this "in my head", but having it accessible on my IPad gives me an added measure of comfort knowing that I did it right, and covered all the factors in conversion, as well as keeping in mind renal and liver precautions. It is very doctor- friendly which is saying a lot; Im not computer savvy. This is EASY! It will also probably be helpful to all the nurses in our hospice program as well. Many thanks for your good efforts! emc md
this app is very easy to use and helpful. the explanations and reference chart are very informative.
Highly recommended! Very user friendly and tremendously useful for inpatient care.
Used this almost daily on the Medicine wards. Far superior to the one in MedCalc. Fast, accurate, and useful. Its clear that the authors spent a lot of thought and had expertise in this area. In particular, the links to the Reference material give you all the details you need to have confidence in dosing opiates. I was particularly impressed by the Methadone dosing, which is not easy to do, and not done accurately in MedCalc. Check out the "Rule of 15s" in the reference material
Nice interface design but limited drugs and (worse) limited dozing route (no iv fentanyl choice??) reduce the usefulness of this for inpatients.
The oxycodone to morphine conversion is incorrect. It should be 2:3, not 1:1.
