What Kind of Pill Is S12? A Comprehensive Guide

4 min read

According to the FDA, thousands of prescription and over-the-counter medications are manufactured with unique imprints to aid identification. However, a simple imprint like 'S12' can correspond to multiple different medications, creating potential confusion and safety risks for anyone unsure what kind of pill is S12. This guide provides a detailed breakdown of the most common drugs associated with this marking, emphasizing that other characteristics like color and shape are crucial for accurate identification.

Quick Summary

A single S12 pill imprint can denote several medications, including treatments for cancer, hypertension, pain, and diabetes. Correct identification relies on matching the pill's unique color and shape, not just the alphanumeric code.

Key Points

  • Imprint is Not Enough: A single 'S12' imprint is used on multiple, vastly different medications, making accurate identification based on the imprint alone impossible.

  • Match Color and Shape: The white, round 'S12' pill is Erlotinib for cancer, while the gray, round 'S12' is Selexipag for pulmonary hypertension.

  • Be Aware of Other Markings: A purple, oval pill with 'Logo S12 1000' is Synjardy for diabetes, showing how additional imprints are critical.

  • Common Pain Reliever: A white, oval 'S12' pill is a prescription-strength Ibuprofen, an NSAID for pain and inflammation.

  • Seek Professional Help: If you cannot positively identify a pill using color, shape, and other markings, do not take it. Consult a pharmacist or doctor to verify its identity.

  • Safety First: Taking the wrong medication can lead to severe health consequences, including adverse drug interactions, allergic reactions, or overdose. Always confirm a pill's identity before consumption.

  • Proper Disposal: Unidentified or leftover medication should be safely disposed of through a pharmacy take-back program to prevent accidental ingestion.

Understanding the 'S12' Imprint

Pharmaceutical manufacturers use imprints to ensure medications can be reliably identified. This system helps pharmacists, healthcare providers, and patients verify the correct drug. While some imprints are unique, others, like 'S12', are more ambiguous and can appear on pills with different active ingredients. For this reason, it is extremely dangerous to rely on the imprint alone for identification. It is essential to consider the pill's color, shape, and any other markings before making a determination.

S12 Pill: White and Round

If you have a white, round pill with the imprint 'S12' on it, it has been identified as a form of Erlotinib Hydrochloride.

About Erlotinib Hydrochloride:

  • Class: This medication belongs to a class of drugs known as Epidermal Growth Factor Receptor (EGFR) inhibitors.
  • Uses: It is a prescription-only medicine used primarily for treating non-small cell lung cancer and pancreatic cancer.
  • Mechanism: Erlotinib works by blocking the signals that tell cancer cells to grow and divide, thereby slowing the progression of the disease.
  • Important Considerations: This is a powerful, targeted chemotherapy drug. Taking it without a prescription or for the wrong condition can have severe health consequences. Common side effects can include diarrhea, rash, fatigue, and nausea.

S12 Pill: Gray and Round

For a gray, round pill with the imprint 'S12', the medication is a form of Selexipag.

About Selexipag:

  • Class: This drug is an agent for pulmonary hypertension, a serious condition affecting the arteries in the lungs.
  • Uses: It is used to treat pulmonary arterial hypertension (PAH).
  • Mechanism: Selexipag works by relaxing the narrowed blood vessels in the lungs, increasing blood flow, and reducing blood pressure.
  • Important Considerations: This is a highly specific medication for a serious condition. Misuse could cause dangerous fluctuations in blood pressure and other side effects, including headache, jaw pain, and diarrhea.

S12 Pill: White and Oval

A white, oval pill with the 'S12' imprint is identified as a form of Ibuprofen.

About Ibuprofen:

  • Class: This is a nonsteroidal anti-inflammatory drug (NSAID).
  • Uses: It is used to treat pain, inflammation, and fever. This particular form is often prescribed for more severe pain conditions, such as back pain or arthritis.
  • Mechanism: Ibuprofen works by blocking the body's production of certain natural substances that cause inflammation.
  • Important Considerations: Although available in lower strengths over-the-counter, this form is prescription-strength. Chronic use can lead to serious side effects, including gastrointestinal bleeding and kidney problems, especially if taken incorrectly.

'Logo S12 1000' Pill: Purple and Oval

In some cases, the 'S12' imprint may be combined with other markings. A purple, oval pill imprinted with 'Logo S12 1000' is a combination drug called Synjardy.

About Synjardy (Empagliflozin / Metformin):

  • Class: This is an antidiabetic combination drug.
  • Uses: It is prescribed for adults with type 2 diabetes to help control blood sugar.
  • Mechanism: It combines two medications: empagliflozin, which helps the kidneys remove sugar from the blood, and metformin, which decreases sugar production in the liver.
  • Important Considerations: This medication carries a risk of serious side effects, including lactic acidosis and ketoacidosis. It is not for type 1 diabetes and should be taken exactly as prescribed under a doctor's care.

What to Do if You Find an Unidentified Pill

If you have found a pill with an 'S12' imprint and are unsure of its origin, follow these safety steps:

  1. Do not consume it. Unless you have a valid, current prescription for the specific medication and can verify its identity, it is not safe to take it. Taking the wrong medication can cause adverse drug interactions, allergic reactions, or overdose.
  2. Compare all characteristics. Use a reputable pill identifier tool, like those from Drugs.com, to match the pill's color, shape, and other markings. Do not rely on the imprint 'S12' alone.
  3. Consult a professional. Take the pill to a pharmacist or a healthcare provider. They can help you identify it definitively and safely dispose of it if necessary. They can also cross-reference it against your prescriptions to see if it's a refill or a leftover.
  4. Consider the source. If the pill was found in a child's possession, contact a healthcare professional or Poison Control immediately. If found in a location that suggests recreational use, remember that street drugs can be counterfeit and contain dangerous substances.
  5. Securely dispose of it. If the pill is not yours, follow your local guidelines for proper disposal. Many pharmacies offer drug take-back programs to prevent accidental poisoning and environmental contamination.

Conclusion

The 'S12' imprint is not a definitive identifier for a single drug but is shared by several distinct medications, each with a different purpose and safety profile. Correct identification requires careful attention to the pill's color, shape, and any other markings present. The differences between a white, round cancer drug and a purple, oval diabetes medication are life-threatening if ignored. The safest course of action for any unidentified pill is to not consume it and to seek professional medical advice for verification. Relying on partial information for pill identification can lead to severe and preventable health risks.

Frequently Asked Questions

Based on the most common medications associated with the 'S12' imprint—Erlotinib, Selexipag, Ibuprofen, and Synjardy—none are classified as controlled substances by the DEA. However, controlled status is not an indicator of a drug's safety, and these medications should only be taken under medical supervision.

Do not take the pill. Take it to a pharmacist for positive identification. If you cannot do that, securely dispose of it through a drug take-back program. Never guess what a pill is or take a medication that was not prescribed to you.

No, the side effects are completely different. Since the imprint 'S12' can appear on medications for cancer, hypertension, pain, and diabetes, the side effects vary drastically depending on the active ingredient. For example, Erlotinib can cause fatigue, while the diabetic medication Synjardy has a risk of lactic acidosis.

You must rely on other characteristics. The white, round 'S12' is Erlotinib (cancer), while the white, oval 'S12' is Ibuprofen (pain). The shape is the key differentiator for these two specific medications.

A drug's complete imprint includes the alphanumeric code, the manufacturer's logo (if any), color, and shape. Manufacturers do not reuse the exact same combination of characteristics. Any ambiguity arises from focusing on just one part of the imprint, such as 'S12', rather than the complete set of identifying features.

No. The white, oval 'S12' is a prescription-strength form of Ibuprofen. Taking this amount without medical supervision could lead to serious side effects, such as stomach bleeding or kidney damage, especially if taken for an extended period.

The full imprint for Synjardy is 'Logo S12 1000'. While some people might shorten it to 'S12', doing so is inaccurate and dangerous. Relying on this partial information could lead to confusion with the other S12 pills.
