Opioids Dosage Conversion App Reviews

Good app! It would be nice to add one or two more drugs, like tramadol.

Really not bad for a free app, but an update with more opioids and more routes of administration would help.

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.

Easy to use, great to use on the wards.

No C/O I find it quick and easy.

Thank you, Chris. Its really simple and useful.

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

And thats a problem. Period.

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.

This conversion app is REALLY SCARY! Im not sure where the table/reference is from but highly inaccurate! I truly hope no one is using this though the idea is great and a similar tool used to be on Epocrates. Most pain management prescribers know Morphine is half a potent as Oxycodone, Oxycodone 1/2-2/3 as potent as oxymorphone and it 1/2-2/3 as potent as hydomorphone.. ie morphine 60 mg=hydrocodone 60mg= Oxycodone 30mg=Oxymorphone 20=Hydromorphone 12= Fentanyl patch 25 mcg Patients will suffer and have major complications including death if anyone uses the current app for equal analgesic dosing! Please DONT!

and I tell all the residents and fellows who rotate with me to download it, with the caveat that the oxycodone conversion is wrong. My only wish is that the oxycodone to morphine ratio would be corrected to 2:3 so I dont have to manually recalculate it. Otherwise the opioid conversion are perfect for palliative medicine.

This calculator is easy to use, and references a commonly used equianalgesic dosing table. I recommend checking with your health-system to see whether this is the ratio card your institution uses. *it includes ratio options taught through EPEC - which is what major academic institutions use, including Institute for Palliative Care at San Diego Hospice. I disagree with the previous commentator suggesting it uses dangerous conversions.

Easy to use

While the app is excellent in assisting pain management providers prescribe opiate medications within a respectable range, I find some major issues: 1. The app does NOT contain the entire gamut of opiates. Although morphine is the absolute gold standard of all decisiveness when trying to prescribe medicine for pain, it leaves two medicines out of any possible equianalgesic dosing - oxymorphone. For people who have this same issue as me, please be aware that oxymorphone is one-half more potent than oxycodone (i.e., 15-20mg oxycodone = 10mg oxymorphone, according to ePocrates) and oxycodone is two-thirds more potent than morphine (i.e., 10mg oxycodone = 15mg morphine, according to that calculation used quite frequently). It also leaves out meperidine/pethidine (even though its a horrible choice for acute pain management - I, myself, am allergic to it). 2. The app does NOT contain all routes of administration. As some of us have mentioned previously, most opiates that are in the app can be administered in other ways than PO (e.g., oxymorphone IV, methadone IV/IM, meperidine/pethidine IM, as earlier mentioned). 3. The app does NOT contain all dosing schedules. Although theres a way to manipulate the dosing schedules in the app to cater to the dosing schedules some of us prefer to have patients (or if a patient uses this, viz. oncology patients, PCA patients) on, the person using the app shouldnt have to manipulate it to get the right schedule. The specialist/patient using the app should have the right to set the dosing schedule to whatever is appropriate. All in all, its significantly helpful, but as I mentioned, it needs some serious updates. I suggest my own as listed above, but I know Im not the only one who has issues with the app. :P Three stars out of five until its done correctly.

Very easy to use and extremely helpful for quick conversions.
