## What is eOpioid™?

INTRODUCTION
eOpioid™ is a sophisticated application with a suite of different functions that can perform complicated opioid pain medication dose calculations.  It can assist healthcare professionals determine proper doses of different opioid pain medicines for patients who may already be using opioids or are opioid tolerant.

(Opioids are sometimes also referred to as opiates or narcotics.)

POWER
Other conventional opioid dose calculators may use the traditional method of simply converting the number of milligrams of one opioid to the number of milligrams of another opioid using a single conversion factor.

eOpioid™, however, is able to produce more complicated calculations for opioids such as methadone or levorphanol, in which the equianalgesic dose is actually not a single value, but a relatively large range of possible values.

VERSATILITY
eOpioid™ not only calculates the number of milligrams for the new, replacement opioid of interest, but searches its database for the replacement opioid's available different sizes of tablets or patches and available dosing time intervals.  It can then display the new opioid dose in terms of a potentially more useful output, such as “morphine ER 30 mg tablet, 1 orally q 8 hours”, rather than just stating “morphine 90 mg”.

An almost unlimited number of separate opioids that a patient may be using can be entered for consideration.  If a patient is simultaneously using many different opioids such as morphine, oxycodone, hydromorphone, etc, these can all be entered.

EXTENSIVE
eOpioid™ has additional functionality to assist clinicians choose appropriate settings for Patient-Controlled Analgesia devices for IV opioids, such as for morphine, hydromorphone, and fentanyl for patients who may be opioid-tolerant.

eOpioid™ has an extensive database of both long-acting and short-acting opioids.  It can assist you in determining the doses for a regimen consisting of a long-acting opioid to be given around-the-clock with a short-acting opioid to be given on an as-needed basis (i.e. “PRN”).

FORM FOLLOWS FUNCTION
Even with the multitude of different features offered with eOpioid™, its interface is refreshingly clean and logical.  It was designed to be intuitive and is a true example of form following function.



Please note that this software is not capable of performing medical consultations.  eOpioid™ is an informational tool only and should only be used by specialized healthcare professionals.  You are required to read the extensive help documentation within eOpioid™ to ensure a thorough understanding of the Software's capabilities and limitations.

### 1/5 — Pain Doc

*2018-02-07, version 1.08*

Doesn’t work on iPhone X

### 5/5 — Opiod Converter

*2016-01-25, version 1.08*

Works well and is an invaluable tool for daily use. Have recommended it to my entire staff.

### 5/5 — What happened to the slider?

*2015-10-03, version 1.08*

I loved the app. Used to use it all the time. No there is no slide bar for equivalents. Not sure what happened to it. Also app crashes whenever I edit current opioids in conversion function. Please fix.

New update:
Thanks for fixing the slider and app crashes when editing current opioids. This is the best opioid conversion app on the market. Use it all the time. I recommend it to all my residents, pharmacists, and students. Keep up the good work.

### 1/5 — Do not buy this app!

*2015-08-20, version 1.06*

I bought this about a month ago. It does not work. It crashes EVERY TIME I use it. There is no slider for equivalence, so it is permanently set at 50%. I can handle that it is annoying and takes extra time and brain power. I have contact support x 3 with NO RESPONSE. I will be requesting a refund ASAP.

### 5/5 — Not functional with no side bar to adjust equivalence

*2015-06-24, version 1.06*

So far this app stinks. It's very frustrating that there is no side bar to adjust the equivalence to 100%. This makes this app useless to me and a waste of my money.

### 1/5 — Not longer works

*2015-03-07, version 1.06*

Not longer works

### 5/5 — Indispensable!

*2013-07-22, version 1.06*

Being in the field of pain management, this app becomes useful several times a day.  It allows for compensation for opioid tolerance and helps to establish a common reference point for a patient's total opiate dose.

### 5/5 — Nurse practitioner

*2013-06-03, version 1.06*

I work with Hospice and use this app daily to convert pain medications. Is extremely user friendly!!

### 5/5 — Love It!!

*2013-02-19, version 1.06*

Excellent tool! Use it frequently especially when pats are on multiple opioids.

### 4/5 — Good app, could contain more info

*2012-08-26, version 1.06*

Good app, could contain more info
