Does the product go bad when temp reaches 77°
Fenzol enclosed a instructions card with shipment stating to store in a cool place & not to allow it to go above 77° ? Does product go bad if allowed to reach this temp. & If it does why would they ship it when outside temp. is in the 90,s?

Dear Greg, Thank you for your inquiry. The Fenbendazole molecule is in itself resistant to heat. While your package may have reached temperatures near 90°F during delivery, please rest assured that Fenbendazole remains chemically stable well beyond that range. Based on published thermogravimetric and calorimetric studies, Fenbendazole does not begin to chemically degrade until it reaches temperatures around 354 °F. Short-term exposure to heat does not compromise the integrity or efficacy of the compound. Please contact us via email if you need more assistance. Looking forward to hearing from you soon. Sincerely, Fen Zol Team
