The Challenge of Pill Identification
Identifying a pill based on its imprint alone can be misleading and potentially dangerous. The code stamped on a pill, such as 'S150', is not a universal identifier unique to one specific drug. Different manufacturers can use the same code for entirely different medications. Therefore, it's critical to also consider the pill's color, shape, and size to correctly identify it. Mistaking one medication for another can lead to ineffective treatment or harmful side effects. This guide will help you understand what different pills with the 'S150' imprint are, but you must always confirm a pill's identity with a healthcare professional.
Identifying the S150 Pill: A Visual Guide
Based on data from pill identification resources, the 'S150' imprint is found on at least two common prescription medications that differ significantly in appearance and use [1.2.2].
- If the pill is Brown or Red and Oval: It is likely a combination drug containing Carbidopa, Entacapone, and Levodopa [1.2.1, 1.2.6]. This medication is prescribed for Parkinson's disease [1.2.5]. The specific strengths are typically 37.5 mg of Carbidopa, 200 mg of Entacapone, and 150 mg of Levodopa [1.2.1].
- If the pill is Yellow and Capsule-Shaped or Oblong: It has been identified as Seysara, which contains 150 mg of the active ingredient sarecycline [1.2.3]. This medication is a tetracycline antibiotic used to treat acne [1.2.3].
- If the pill is White and Oval: It may be Vykat XR, a brand name for diazoxide choline [1.2.4, 1.2.7].
In-Depth Look at S150 Medications
Carbidopa/Entacapone/Levodopa for Parkinson's Disease
The brown or red oval S150 pill is a medication used to manage the symptoms of Parkinson's disease [1.2.1, 1.2.5]. Parkinson's is a neurodegenerative disorder that affects movement. This medication combines three active ingredients to improve effectiveness:
- Levodopa: This is the primary active ingredient. It is converted into dopamine in the brain, helping to replenish the brain's low supply of this crucial neurotransmitter.
- Carbidopa: This ingredient prevents Levodopa from being broken down in the bloodstream before it reaches the brain. This allows for a lower dose of Levodopa to be effective and reduces side effects like nausea.
- Entacapone: This is a COMT inhibitor that prolongs the effect of Levodopa by blocking an enzyme that breaks it down. This helps to reduce 'off' time for patients.
Common side effects can include involuntary movements (dyskinesia), nausea, dizziness, and hallucinations [1.2.1].
Seysara (sarecycline) for Acne
The yellow, oblong S150 pill is Seysara, an antibiotic used to treat severe inflammatory acne vulgaris [1.2.3]. It belongs to the tetracycline class of antibiotics and works by inhibiting the growth of bacteria that contribute to acne. It also has anti-inflammatory properties that help reduce the redness and swelling of pimples.
As a tetracycline antibiotic, common side effects can include nausea, lightheadedness, and increased sensitivity to the sun, requiring patients to use sunscreen and protective clothing when outdoors [1.2.3].
Comparison of Common 'S150' Pills
To avoid confusion, this table summarizes the key differences between the most common medications bearing the 'S150' imprint.
| Pill Appearance (Imprint, Color, Shape) | Medication Name(s) | Primary Use | Drug Class |
|---|---|---|---|
| S150, Brown, Oval | Carbidopa, Entacapone, and Levodopa | Parkinson's Disease [1.2.1] | Dopaminergic antiparkinsonism agents [1.2.1] |
| S150, Yellow, Capsule/Oblong | Seysara (sarecycline) | Acne [1.2.3] | Tetracyclines [1.2.3] |
Conclusion: Always Verify with a Professional
The existence of multiple, very different medications with the 'S150' imprint underscores a critical point in medication safety: never rely on a single piece of information to identify a pill. Taking a Parkinson's medication for acne, or vice versa, could have serious health consequences. If you find a loose pill or are unsure about your medication, do not guess. The safest course of action is to contact your pharmacist or doctor. They can provide a definitive identification and ensure you are taking the correct medication for your specific health needs.
