Learn to recognize the drugs, devices and shorthand you see every day in refills, prior auths, patient messages and chart prep, and learn exactly when to hand something to a provider.
You do not need to be a clinician. You need to read a medication name correctly, notice when something does not match, and know who gets it next. Most of your work is on the phone, so the Phone scripts tab has what to say.
No medical background needed. Here is how diabetes and thyroid medicines work, in pictures and everyday words.
Think of a marathon runner and a sprinter. The marathon runner (background insulin, like Lantus or Tresiba) jogs steadily all day. The sprinter (mealtime insulin, like Novolog, Fiasp or Humalog) dashes in when food arrives, then fades. Fiasp is a slightly quicker sprinter than Novolog.
Prefilled. The patient dials the number of units. Needs pen needles, which are a separate prescription.
The patient draws insulin into a syringe. Needs syringes, also a separate prescription.
A small machine that drips rapid-acting insulin all day through a thin tube and a patch on the skin.
Fiasp PumpCart is a prefilled cartridge that loads into a pump. It is not a pen, and a pen cannot go in a pump.
A small disc on the arm or belly reads sugar all day and sends it to a phone. Like a smoke detector for sugar.
Most insulin is clear. NPH and premixed insulins (like Novolog Mix 70/30) are cloudy and get rolled gently before use.
Simplified picture, not to scale.
Zones tell you when to speak up. They are not for treating or changing doses.
The ending of the generic name tells you the family, even if you have never seen the drug.
| If the name has | It is | Examples |
|---|---|---|
| insulin ___ | Insulin (a shot) | insulin aspart (Novolog, Fiasp), insulin glargine (Lantus) |
| -tide | GLP-1 type weekly or daily shot | semaglutide (Ozempic), tirzepatide (Mounjaro), liraglutide (Victoza) |
| -gliflozin | SGLT2 pill (kidneys flush sugar) | empagliflozin (Jardiance), dapagliflozin (Farxiga) |
| -gliptin | DPP-4 pill | sitagliptin (Januvia), linagliptin (Tradjenta) |
| glipizide, glimepiride, glyburide | Sulfonylurea pill. Can cause lows. | Glucotrol, Amaryl |
| metformin | The foundation diabetes pill | Glucophage. Also inside Janumet, Synjardy. |
| levo-, thyro- | Thyroid hormone pill | levothyroxine (Synthroid), liothyronine (Cytomel) |
| -azole at the end | Turns an overactive thyroid down | methimazole (Tapazole) |
Two jobs: mealtime insulin covers a meal, basal (background) insulin works around the clock. Many patients take both.
Approximate maximum duration. Varies from person to person. For recognition only.
| Family | Brands | Taken | Remember |
|---|---|---|---|
| Rapid-acting | Novolog, Fiasp (aspart) · Humalog, Admelog, Lyumjev (lispro) · Apidra (glulisine) | With meals | Clear. Starts in minutes. Lyumjev and Fiasp are the fastest-starting versions. |
| Regular (short) | Humulin R, Novolin R | About 30 minutes before meals | Slower and longer than rapid-acting. Sold without a prescription in the US, but insurance only covers it with one. |
| NPH (intermediate) | Humulin N, Novolin N | Usually once or twice daily | Cloudy, unlike every other insulin here. Needs gentle rolling before use. |
| Long-acting (basal) | Lantus, Basaglar, Semglee, Rezvoglar (glargine U-100) · Toujeo (glargine U-300) · Tresiba (degludec) · Levemir (detemir) | Once daily, same time | No peak, steady background. Levemir is being phased out, so expect provider-chosen replacements. |
| Premixed | Novolog Mix 70/30, Humalog Mix 75/25, Humulin 70/30, Novolin 70/30 | Usually with breakfast and dinner | Two insulins in one pen. The numbers are the percentage split. Cloudy. |
| Insulin + GLP-1 | Soliqua, Xultophy | Once daily | One pen, two drug classes. Counts as both when a form asks. |
| Inhaled | Afrezza | Start of meal | Powder cartridges, not an injection. |
U-100 means 100 units in every 1 mL. It is the standard. Higher strengths exist and are easy to mix up:
U-200 Humalog KwikPen, Tresiba · U-300 Toujeo · U-500 Humulin R U-500 (five times standard, high-alert).
Pen: prefilled, dials in units, needs separate pen needles.
Vial: drawn into a syringe. Needs insulin syringes.
Cartridge or pump reservoir: goes in a reusable pen or an insulin pump.
The same insulin comes in different containers. The words on the prescription tell you which one. Each needs different supplies, so they are not interchangeable.
| Label says | What it is | Patient also needs | How much insulin |
|---|---|---|---|
| "Solution" (100 units/mL) | The vial. A bottle the patient draws from. | Insulin syringes. Some pump users fill their pump from a vial. | 10 mL = 1,000 units |
| "Solution pen-injector" | A prefilled pen (FlexPen, FlexTouch, KwikPen). Dial the units and inject. | Pen needles | 3 mL = 300 units per pen |
| "Cartridge" (PenFill) | A small insulin cartridge that loads into a reusable pen. Not a prefilled pen. | A compatible reusable pen and pen needles | 3 mL = 300 units |
| Fiasp "PumpCart" | A prefilled cartridge made for an insulin pump. It cannot be used in a pen. | The matching pump and infusion sets | 1.6 mL = 160 units |
Units matter for refills. A vial lasts far longer than one pen, so "refill too soon" rejections depend on the container.
Unopened insulin lives in the refrigerator and is never frozen. An opened pen or vial can usually stay at room temperature for about 28 days, then it is thrown away even if some remains. Tresiba and Toujeo allow longer (about 56 days). Heat and sunlight ruin it. The package insert is the final word. If a patient says insulin was left in a hot car or froze, route it to a provider.
Tap the card to flip it. Say the answer out loud first. Mark "Need practice" and the card comes back soon.
A medicine name appears. Tap the family it belongs to. Twelve per round, in a new order each time.
Most of your work happens on the phone. Here is what to say and what to do on the calls you will get most.
Examples: the chart says Lantus and the pharmacy calls about Toujeo, or the chart says Novolog and they call about Fiasp. Each pair is the same insulin (glargine, or aspart) sold under different brand names.
Say: "Can you spell the full name for me and read the strength on the box? Is it the vial, the pen, or the pump cartridge?"
Do: write down the name, strength, whether it is a vial, pen or pump cartridge, and how often. Route it to the provider the same day. Never approve a different brand, strength or device on your own (apart from the same-insulin cost switch above).
Say: "Which insulin is it, and when was your last dose? I am flagging this to the in-person staff right now."
Do: mark it same-day urgent. Ask for the pharmacy name and phone number so the provider can act quickly.
Say: "I am getting the in-person staff on the line for you now. Please stay on the phone."
Do: alert the in-person staff immediately. If they say they cannot keep fluids down, have trouble breathing, or pass out, tell them to call 911.
Say: "I cannot change doses, but I will get your question to the provider today."
Do: write the question and the recent sugar readings word for word. Route it as same-day.
Say and do: use the low blood sugar script. Alert the in-person staff at the same time.
Confirm identity per clinic policy. Repeat the medicine name and strength back to the caller. Write down the call-back number. End with what happens next and when.

Wrong-drug errors usually come from names that look or sound alike. Slow down on these pairs.
| Pair | Difference |
|---|---|
| Novolog / Novolin | Novolog is rapid-acting aspart. Novolin is human insulin (R, N or 70/30). |
| Humalog / Humulin | Humalog is rapid-acting lispro. Humulin is human insulin. Humulin R U-500 is a concentrated, high-alert product. |
| Novolog / Fiasp | Same insulin (aspart). Fiasp starts a little faster. A cost or insurance switch is okay to proceed with. See Phone scripts. |
| Lantus / Toujeo | Same insulin (glargine), different pen strength (U-100 vs U-300). A cost or insurance switch between glargine brands is okay to proceed with. See Phone scripts. |
| Toujeo / Tresiba | Different long-acting insulins with names that look alike on a screen. |
| Januvia / Janumet | Janumet is Januvia plus metformin. |
| Januvia / Jardiance | Januvia is a DPP-4 pill. Jardiance is an SGLT2 pill. |
| Ozempic / Wegovy | Same drug (semaglutide). Ozempic is for type 2 diabetes. Wegovy is for weight and heart risk. Insurance treats them differently. |
| Mounjaro / Zepbound | Same drug (tirzepatide). Mounjaro for diabetes, Zepbound for weight and sleep apnea. |
| Ozempic / Rybelsus | Both semaglutide for diabetes. Ozempic is a weekly shot, Rybelsus is a daily pill. |
| Victoza / Saxenda | Same drug (liraglutide). Victoza for diabetes, Saxenda for weight. |
| glipizide / glimepiride / glyburide | Three different sulfonylureas, all can cause low blood sugar. Read every letter. |
| metformin IR / ER | Immediate release versus extended release. Not interchangeable on the label. |
| levothyroxine brands | Synthroid, Levoxyl, Unithroid, Euthyrox. Patients are often kept on one brand, so do not swap. |
Use this when a patient reports sugar under 70 with shakiness, sweating or confusion, or any reading under 54. Alert the in-person staff at the same time. Do not wait until after the call.
