A pill bottle is a small container, typically made of plastic or glass, designed to hold and protect medications or pills. It usually has a screw-on or snap-on lid that provides a secure seal to keep the contents safe and to prevent moisture, air, or other contaminants from affecting the medication.

Pill bottles are commonly used in healthcare settings, pharmacies, and households to store prescription medications, over-the-counter drugs, vitamins, supplements, and other types of pills. They come in various sizes, shapes, and colors, often with labels indicating the medication's name, dosage instructions, expiration date, and other relevant information.

The design of pill bottles may include child-resistant caps to help prevent accidental ingestion by young children. Some pill bottles also come with features like desiccants to absorb moisture and help maintain the stability of the medication.

In recent years, there has been a push for more eco-friendly and sustainable packaging options, including biodegradable or recyclable pill bottle materials, to reduce the environmental impact of healthcare-related waste.
