Losartan tablets can differ by maker and dose, so match the imprint code, shape, and color to your prescription label.
If you just picked up a refill and the tablet looks different, you’re not alone. Losartan is a common blood-pressure medicine, and many companies make it. Generics can change appearance when a pharmacy switches suppliers. The safest move is to confirm what you have before you take it.
This article gives you a clear way to identify a losartan tablet using the bottle label, the imprint code, and a trusted reference. If you typed that question into a search bar, you’ll also see real-world examples from official labeling so you know what “normal variation” looks like.
Losartan basics and why looks differ
Losartan is a prescription tablet taken by mouth. Many people take it once a day, and some take it twice a day, based on their prescriber’s plan. Losartan is used to treat high blood pressure and related conditions, depending on your diagnosis and plan of care.
When the same drug is made by different manufacturers, the active ingredient stays the same, but the tablet can vary in color, imprint, and shape. Fillers, coating, and each company’s imprint code can differ. That’s why a refill can look new even when the medication is still losartan.
Three checks that beat guessing
- Prescription label: Start with the drug name and strength (mg) printed on the bottle.
- Imprint code: Letters and numbers stamped on the tablet are the fastest match.
- Shape and color: Use these to confirm the imprint match, not as the only clue.
What Does Losartan Pill Look Like? for brand-name Cozaar
Cozaar is the brand name for losartan potassium. Brand tablets have markings listed in the FDA-approved label: 25 mg tablets are white and oval with code 951; 50 mg tablets are white, oval, and scored with code 952; 100 mg tablets are white and teardrop-shaped with code 960.
If your bottle says Cozaar and the codes don’t match, pause and verify before taking a dose. Brand tablets are less likely to change code across refills, so a mismatch deserves a call to the pharmacy.
| What you see | What it can suggest | What to do next |
|---|---|---|
| Imprint 951 on a white oval tablet | Cozaar 25 mg | Match to your label strength and take only if it aligns |
| Imprint 952 on a white oval tablet, scored | Cozaar 50 mg | Confirm score line and strength on the bottle |
| Imprint 960 on a white teardrop tablet | Cozaar 100 mg | Confirm the strength on the label before taking it |
| Green oval tablet with “E” and a two-digit code | One common generic style | Use the full imprint (both sides) in a pill ID lookup |
| White round tablet with short letter/number imprint | Another generic style | Confirm mg on the bottle; don’t rely on color alone |
| No imprint at all | Not typical for U.S. prescription tablets | Call the pharmacy before you take it |
| Tablet is chipped, smudged, or unreadable | Imprint match is harder | Set it aside and ask for a clear replacement |
| Label says losartan/HCTZ but pill looks like plain losartan | Possible mix-up | Check the NDC on the label and confirm with the pharmacy |
A quick pill check you can do in under a minute
If you’re staring at a tablet and thinking, “what does losartan pill look like?”, this routine keeps you on track even on a rushed morning.
Step 1: Read the bottle, not the tablet first
Check the drug name, strength, and directions on the prescription label. If the label includes an NDC, jot it down. The NDC points to the exact packaged product.
Step 2: Copy the full imprint from both sides
Flip the tablet and write every letter and number. Include spaces if they’re printed. If the tablet is scored, note that too. One character can change the match.
Step 3: Confirm shape and color after the imprint match
Now match the shape and color to the description in a trusted reference. Color alone is a weak clue. Shape plus imprint is much stronger.
Step 4: Compare against official labeling when possible
DailyMed hosts the official labeling submitted to the U.S. National Library of Medicine, and many listings include package images. Use DailyMed losartan potassium tablet labeling to compare descriptions like color, shape, and debossed markings.
Step 5: If anything doesn’t match, stop and verify
Mix-ups happen most often at transition points: a new refill, a new pharmacy, or a new bottle at home. If the imprint does not match your label or trusted reference, don’t take the dose. Call your pharmacy and ask them to confirm the imprint and NDC tied to your fill.
Common losartan tablet looks you may see at pharmacies
Generic losartan can appear in many styles. A few show up often in U.S. listings and labels, so seeing them doesn’t mean something is wrong.
Green oval tablets with “E” plus a number
One set of common generics uses green, oval tablets with an “E” on one side and a two-digit number on the other. In pill image references and in some label descriptions, you’ll see E 45 (25 mg), E 46 (50 mg), and E 47 (100 mg).
White oval or capsule-shaped tablets with short codes
Many losartan tablets are white and oval, sometimes capsule-shaped. Codes differ by company, so the imprint is the deciding factor. If your tablet is white and oblong, it can still be losartan, but you should match the exact letters and numbers.
Scored tablets
Some 50 mg tablets are scored. A score line can help with certain dosing plans, yet you should not split a tablet unless your prescriber or pharmacist has told you to do so.
Red flags that mean you should pause before taking it
Most appearance changes come from a supplier switch. Some signals still call for a stop-and-check.
- Strength mismatch: Your label says 50 mg, but the tablet matches a 25 mg imprint, or the other way around.
- No imprint: U.S. prescription tablets usually carry an imprint that identifies the product or maker.
- Damaged tablet: Chips and smudges can blur the imprint and make identification unreliable.
- Mixed tablets in one bottle: A single odd tablet in an otherwise uniform bottle is a bigger concern than a full bottle change.
If you have a pill you can’t match and it’s not an emergency, the FDA describes how its Division of Drug Information can help with drug identification based on appearance and markings. The details are on the FDA Drug Identification page.
How to match losartan to your own prescription label
It’s tempting to compare your tablet to one photo online and call it done. Photos help, but your bottle label gives the tightest match for your fill. Use these points to line things up.
Use the strength first
Losartan tablets are commonly dispensed as 25 mg, 50 mg, or 100 mg. Start with that number, then match the imprint for that strength in the same reference source.
Use the NDC when your label includes it
The NDC ties your fill to a specific manufacturer and package. If your pharmacy prints it, it’s a fast way to confirm that a pill description applies to your bottle.
Check both sides and note any score line
Some tablets have a single letter on one side and numbers on the other. Others place the full code on one side. Record both sides before you compare, and note any score line as part of the match.
Use one source per match
Jumping across multiple photo sets can lead to false matches. Pick one trusted database, match the imprint, then use shape and color as your confirmation.
Tablets, doses, and what can change between manufacturers
The same dose can show up with different looks. You don’t need to memorize each style. You just need to know what must line up for your bottle.
| Item | What stays fixed | What can vary |
|---|---|---|
| Active ingredient | Losartan potassium | Inactive ingredients and dyes |
| Strength | Printed on your label | Tablet size and thickness |
| Imprint role | Identifies product or maker | Exact letters and numbers |
| Tablet color | Often consistent within one NDC | White, green, or other shades |
| Tablet shape | Consistent within one product | Oval, round, teardrop, oblong |
| Coating feel | Often film-coated | Surface texture and finish |
| Score line | Present on some products | Scored vs unscored |
| Package labeling | NDC and lot info | Bottle size and label layout |
Storage and handling that keep tablets identifiable
If the imprint rubs off, pill ID gets harder. A few habits keep tablets in better shape.
Keep tablets in the original bottle
Loose tablets in a pocket or bag pick up moisture and friction. That can smudge the imprint and chip the edges.
Store in a dry place at room temperature
Heat and humidity can wear down coatings over time. A dry cabinet away from the stove and shower is a better spot than a bathroom counter.
Don’t mix leftovers into a new fill
If you combine bottles, you can end up with two looks in one container, and that makes later identification harder. Finish one bottle before you start the next when you can.
When to get urgent help
If you think you took the wrong pill and you feel unwell, treat it as urgent. Call local emergency services for severe symptoms. In the United States, Poison Control is available at 1-800-222-1222 for possible poisoning or medication mistakes.
If you have no symptoms and you just have a mismatch, stop and verify. Save the tablet and the bottle, then call the pharmacy so they can check the imprint against your prescription record.
A fast checklist before your next dose
- Read the label: drug name, strength, directions.
- Write the imprint from both sides.
- Match the imprint in one trusted reference.
- Confirm shape and color after the imprint match.
- If anything doesn’t line up, call the pharmacy before taking it.
People search what does losartan pill look like? because something changed. Most of the time it’s a supplier switch. Your job is to confirm imprint and strength so you take the right tablet.
