What people are saying

★★★★★

“I used to page the pharmacist for every C-II partial fill. The first week with the guide, a patient wanted half her Adderall, and I had the 30-day rule and the notation ready in under a minute. My pharmacist just initialed it and moved on.”

Jessica M.CPhT, Columbus, OH
★★★★★

“Our biennial inventory used to eat a whole Sunday because nobody agreed on what needed an exact count. Chapter 16 settled it in two lines. We finished before lunch, and when the Board inspector came in March, the binder was the first thing she asked for.”

Amanda R.Pharmacist-in-Charge, Knoxville, TN
★★★★★

“Three weeks into my first tech job, a C-II came in with no date and I froze. Now I run the 60-second check on every controlled script. Last month a DEA number on a C-IV phone-in didn't add up, and I flagged it right away.”

Brianna T.Pharmacy Technician, Mesa, AZ
★★★★★

“Controlled substances were the part of the PTCE I kept missing, because every study guide said something a little different. Having schedules, refills and transfers in one table finally made it stick. I passed on my first try and kept the guide for my new job.”

Maria L.Pharmacy Tech Student, San Antonio, TX

Who is it for?

💊
Pharmacy technicians

who handle controlled scripts every day and want to know what to check and when to call the pharmacist.

🩺
Community pharmacists

who want the rule confirmed in seconds before they verify, with the line still moving.

📋
PICs and pharmacy owners

who answer for records, inventory, ordering and the next DEA or Board inspection.

🎓
Students and new grads

who want to walk into their first counter already knowing how the routine works.

Who made the guide

Rx Tech From Home makes visual, plain-English references for the people behind the pharmacy counter. We took the Controlled Substances Act, the DEA regulations and the questions that come up on every shift, and turned them into tables, schemes and checklists you can find in seconds. Every rule points to its federal source, and every chapter tells you where your state can be stricter.

Before you decide

The DEA rules are free online. Why a guide?
They are, and they should be. But dispensing today depends on the Controlled Substances Act, the DEA regulations, CARA, the CMEA, the EPCS rules and the changes that came after them. The guide puts all of it in one place, in tables and schemes, with the federal source for each rule.
Is it updated with e-prescribing and the latest rules?
Yes. The 2026 Edition covers EPCS, partial fills of C-II, buprenorphine after the end of the X-waiver, PDMP checks and the current DEA forms.
What happens when the rules change again?
You get 1 year of free updates. The new version is sent to the same email you used to buy.
I've worked the counter for years. Is it for me?
Yes, as a fast double-check on the exceptions and on what changed lately: partial fills, transfers, EPCS, buprenorphine and what inspectors ask for now.
Does it work for pharmacy techs?
It does. It's written in counter language, with what to check on each prescription and when to bring in the pharmacist. The final verification is always the pharmacist's.
Does it cover my state?
It covers the federal rules that apply in every state, and it flags every point where states are often stricter (C-II validity, PDMP checks, opioid day limits, e-Rx mandates) so you know exactly what to confirm with your state board.
How do I get it?
Right after your payment is confirmed, you get access by email. The 3 bonuses come with it, on the same day.
Can I print it?
Yes, for personal use. Many people print only the tables they use the most and keep them at the station.
What if it's not what I expected?
You have a 7-day money-back guarantee. Just ask for a refund and you get your money back.

On your next controlled Rx, the answer will be in your hand.
