How to store Allegra correctly?
Short answer
Medication question
Store Allegra tablets at room temperature in a cool, dry place — away from heat, moisture, and direct sunlight. Avoid the bathroom medicine cabinet. Keep it in the original packaging, out of reach of children. Liquid Allegra (children's suspension) has its own label instructions and should not be used past the expiration date.

Key facts
Allegra tablets should be stored at room temperature, protected from heat, light, and moisture per the product labeling.
Bathroom cabinets expose medications to repeated humidity and temperature changes from showers, accelerating breakdown.
Liquid oral medications are generally less stable than solid tablets and may require different storage conditions.
Here's the nuance
A one-liner rarely tells the whole story. This is the honest detail behind the short answer above.
Like most solid oral medications, Allegra (fexofenadine) tablets are best stored at room temperature in a place that stays consistently cool and dry. The main enemies of tablet stability are heat, humidity, and direct light — all of which can accelerate chemical breakdown and degrade potency over time, even before the printed expiration date.
The bathroom medicine cabinet is the most common mistake. Despite being the obvious home for medications, bathrooms cycle through heat and steam from showers and baths repeatedly each day, creating conditions that are exactly wrong for storage. A bedroom dresser drawer, a kitchen shelf away from the oven or sink, or a dedicated medicine storage box in a cool, dry location are all better choices.
Keep Allegra in its original container or packaging. The blister packaging and original bottles are designed to protect the tablets from moisture and light. If you transfer pills to an unmarked container, you also lose expiration date information. Store out of the reach of children — this is particularly important with any medication in tablet form.
For liquid Allegra (children's suspension), follow the storage instructions on that specific product's label — liquid formulations typically have different temperature requirements and are often less stable than tablets. A liquid Allegra that has been stored poorly or is past its expiration date should be discarded rather than used. If you're unsure about a particular product's storage needs, the label or a pharmacist will have the specifics.
The key points
The handful of things that decide the answer — skim these if you only read one section.
Room temperature, cool and dry
Allegra tablets are stable at standard room temperature. Avoid anywhere that gets hot, humid, or has dramatic temperature swings throughout the day.
Avoid the bathroom cabinet
Bathroom medicine cabinets expose tablets to steam and heat cycles with each shower. Despite the name, they're not a good long-term storage spot for medications.
Keep it in original packaging
Blister packs and original bottles help protect against moisture and light. They also preserve expiration date information, which is important for knowing when to replace your supply.
Liquids need extra care
Children's Allegra liquid suspension may have different temperature requirements than tablets. Check that product's label specifically, and do not use liquid Allegra past its expiration date.
Out of reach of children
Store Allegra where children cannot access it. Child-resistant caps on original bottles offer protection, but placement matters too — a high shelf or locked cabinet is best.

Frequently Asked Questions
It is generally not recommended. Bathrooms are subject to repeated cycles of heat and humidity from showers — conditions that can degrade tablet medications over time. Even if a bathroom medicine cabinet has a closed door, daily steam exposure accumulates. A bedroom dresser drawer or a dry kitchen shelf is a better choice for long-term storage of Allegra tablets.
Allegra tablets do not need refrigeration — standard room temperature storage in a cool, dry location is appropriate. Refrigeration is sometimes recommended for certain liquid medications; for children's Allegra suspension, follow the specific label instructions on that product. When in doubt, read the storage section of the package insert or ask a pharmacist.
Yes. Excessive heat is one of the main factors that can break down medications faster than their printed expiration date would suggest. Avoid leaving Allegra in a hot car, near a heater, or in a window where it gets direct sun. A place where temperature stays consistently moderate — like a bedroom drawer or interior shelf — is preferable.
As long as it is stored correctly and you use it before the printed expiration date on the packaging, an open box of Allegra tablets should remain effective. The expiration date reflects the manufacturer's guarantee of full potency under proper storage conditions. If tablets appear crumbling, discolored, or unusual in any way, or if storage conditions were poor, discard and replace them.
