Viagra tablets come in three colors depending on strength

Viagra (sildenafil citrate) tablets are color-coded by dose. The 25 mg tablet is white, the 50 mg tablet is blue, and the 100 mg tablet is also blue but darker. The shape is diamond on all three strengths. This color system helps you and your pharmacist confirm you have the right dose before you take it.

The blue color of the 50 mg and 100 mg tablets comes from the dye added during manufacturing. The white 25 mg tablet contains no dye. All three are imprinted with the Pfizer logo and the dose number so you can verify the strength by sight and touch.

If you receive a tablet that does not match this description — a different color, shape, or missing imprint — do not take it. Contact your pharmacist or doctor before using it. Counterfeit versions exist and may contain harmful substances or incorrect doses.

Key Takeaways

  • The 25 mg Viagra tablet is white and diamond-shaped with no dye.
  • The 50 mg and 100 mg tablets are both blue and diamond-shaped, with the 100 mg being a darker shade.
  • All genuine Viagra tablets carry a Pfizer imprint and the dose number on the surface.
  • Tablets that differ in color, shape, or markings should not be used and should be reported to your pharmacist.

How to read the imprint on your tablet

The imprint on a Viagra tablet tells you the dose and confirms it came from Pfizer. The 25 mg tablet is marked "PFIZER VGR 25". The 50 mg tablet is marked "PFIZER VGR 50". The 100 mg tablet is marked "PFIZER VGR 100". These markings are raised or indented into the tablet surface and should be clear and straightforward to read.

If the imprint is blurry, missing, or different from what is listed above, the tablet may be counterfeit or damaged. Store-bought medications should always have a clear imprint. If you have any doubt, ask your pharmacist to verify the tablet before you take it.

Why Viagra tablets are color-coded

Color-coding serves a safety purpose. It lets you see at a glance what dose you are holding, which reduces the chance of taking the wrong strength by mistake. This is especially important if you take multiple medications or if someone else in your household uses the same medication at a different dose.

The color also helps pharmacists catch errors during dispensing. If a pharmacist fills a prescription for 50 mg but the bottle contains white tablets, the mismatch is visible and can be corrected before you leave the pharmacy.

Storing your Viagra tablets safely

Keep Viagra tablets in their original container with the label intact. The label shows the dose, your name, the date filled, and the pharmacy contact information. Store them at room temperature, away from heat and moisture. Do not transfer them to a pill organizer or unmarked container, as this removes the color and imprint that identify the dose.

If you use a pill organizer for other medications, keep Viagra in its original bottle and remove one tablet only when you are ready to take it. This practice prevents confusion and keeps the dose information visible.

What to do if your tablets look different

If your Viagra tablets are a different color or shape than described here, or if the imprint is missing or unclear, contact your pharmacy before taking them. Bring the bottle and the tablets with you if possible. Your pharmacist can verify whether the tablets match your prescription or if there has been an error.

If you suspect you have received counterfeit medication, report it to your pharmacy and to the FDA's MedWatch program. You can report online at fda.gov/medwatch or by phone at 1-888-SAFEMED. Providing this information helps protect others from receiving fake or unsafe medication.

Generic sildenafil tablets may look different

If your doctor prescribes generic sildenafil instead of brand-name Viagra, the tablets may be a different color and shape. Generic versions are made by other manufacturers and are not required to look the same as the original. A generic 50 mg sildenafil tablet might be white, blue, or another color depending on the maker.

The dose and imprint will still be printed on the tablet, and your pharmacist will confirm the dose matches your prescription. Generic sildenafil works the same way as Viagra and is equally safe, but the appearance will differ. Always check the label on your bottle to confirm the dose, regardless of the tablet color.

Frequently Asked Questions

Are all blue tablets Viagra?

No. Many medications are blue. Only Viagra tablets marked with "PFIZER VGR" and a dose number are genuine Viagra. Other blue tablets may be different medications entirely. Always check the imprint before taking any tablet.

Can I cut a Viagra tablet in half?

Yes, if your doctor has told you to do so. The 50 mg and 100 mg tablets can be split. The 25 mg tablet is small and difficult to split evenly. Ask your pharmacist or doctor whether splitting is right for your dose before you try it.

What if I have old Viagra tablets that look faded?

Do not use faded or discolored tablets. Exposure to light, heat, or moisture can break down the medication and make it less effective or unsafe. Discard old tablets at a pharmacy or follow your local medication disposal guidelines. Do not flush them unless the label says it is safe to do so.

Is generic sildenafil as safe as Viagra?

Yes. Generic sildenafil contains the same active ingredient and works the same way. It must meet the same FDA safety and quality standards as brand-name Viagra. The only difference is the appearance and the price — generic versions are usually less expensive.
