Proper storage significantly impacts azithromycin’s lifespan. Keep tablets in their original container, tightly closed, and in a cool, dry place away from direct sunlight and excessive heat. Avoid temperatures exceeding 25°C (77°F).
Exposure to moisture is a primary degrader. High humidity accelerates the breakdown of the active ingredient. A damp environment will shorten the shelf life considerably. Use a desiccant pack if necessary.
Light exposure, particularly ultraviolet light, can damage the drug. Avoid storing azithromycin in direct sunlight or under bright artificial lights. Opaque containers offer better protection.
Time is a factor. While manufacturers print expiration dates, the drug’s potency diminishes gradually after production. Using medication past its expiration date increases the risk of reduced effectiveness.
Improper handling also matters. Avoid crushing or chewing the tablets unless specifically instructed by a physician. Contamination from handling can accelerate deterioration.
