See the DrugPatentWatch profile for Hydroxyzine
The shelf life of hydroxyzine HCl, like many medications, is determined by stability testing and is typically indicated by an expiration date on the product packaging. This expiration date signifies the time until which the manufacturer guarantees the full potency and safety of the drug when stored under recommended conditions [1].
What are the recommended storage conditions for Hydroxyzine HCl?
Hydroxyzine HCl should generally be stored at controlled room temperature, typically between 20°C and 25°C (68°F and 77°F). It is important to protect the medication from excessive heat, light, and moisture, and to keep it in its original container [1][2].
How does the expiration date affect Hydroxyzine HCl?
Once a medication reaches its expiration date, its chemical composition may begin to degrade. This degradation can lead to a decrease in the drug's effectiveness and, in some cases, the formation of potentially harmful byproducts. Therefore, it is advised not to use hydroxyzine HCl or any medication past its printed expiration date [1][3].
Can pharmacies dispense expired Hydroxyzine HCl?
Pharmacies are not permitted to dispense expired medications, including hydroxyzine HCl. Regulations typically prohibit the dispensing of drugs beyond their expiration date to ensure patient safety and medication efficacy [4].
What happens if Hydroxyzine HCl is stored improperly?
Improper storage conditions, such as exposure to extreme temperatures or humidity, can accelerate the degradation of hydroxyzine HCl, potentially causing it to lose potency or become unsafe for use before its printed expiration date [1][3].
