Understanding the appearance of your medication is important for safety, proper dosing, and avoiding confusion-especially when different brands or generics are involved.In this comprehensive guide, we'll explore the levothyroxine 100 mcg pill picture, including its color, shape, markings, and how it varies across brands like Synthroid, Levoxyl, Tirosint, and generic manufacturers.We'll also cover dosage tips, side effects, and how to identify your pill correctly using a levothyroxine 100 mcg tablet image as a reference.
Levothyroxine 100 mcg Pill Identifier: Key Features
Levothyroxine sodium is a synthetic form of the thyroid hormone thyroxine (T4), used to treat hypothyroidism-a condition where the thyroid gland doesn't produce enough hormones.The 100 mcg dose is one of the most commonly prescribed strengths, especially for adults with moderate to severe thyroid deficiency.
While all levothyroxine 100 mcg tablets contain the same active ingredient, their appearance can differ significantly based on the manufacturer.This is where a levothyroxine 100 mcg capsule photo or tablet image becomes helpful for visual identification.
General Appearance of Levothyroxine 100 mcg
Despite brand differences, most 100 mcg levothyroxine pills share some common traits:
- Color: White, blue, purple, yellow, or green
- Shape: Round, oval, capsule-shaped, or shield-shaped
- Size: Small to medium, easy to swallow
- Markings: "100" imprinted on one side, often with a brand name or manufacturer code
These visual cues help patients and pharmacists distinguish between different dosages.For example, lower doses like 25 mcg are typically yellow, while higher doses such as 100 mcg are often blue, purple, or white.
Why Do Levothyroxine Pills Look Different?
You might see a levothyroxine 100 mcg pill picture online showing a blue round tablet, but your prescription could be white and oval.This variation is normal and due to several factors:
- Brand Identity: Manufacturers use unique colors and shapes to distinguish their products (e.g., Synthroid's blue tablet).
- Dosage Safety: Distinct appearances help prevent medication errors between strengths.
- Inactive Ingredients: Fillers, dyes, and binders affect color and texture but not the drug's effectiveness.
- Release Formulation: Some versions, like Tirosint, come in gel capsules for improved absorption.
Regardless of appearance, all FDA-approved levothyroxine 100 mcg tablets contain the same active ingredient and are bioequivalent, meaning they work the same way in the body.
