Zhewitra 10 mg contains vardenafil 10 mg, a medicine used for erectile dysfunction. Heat can affect it because high temperatures can reduce the stability of the active ingredient and other tablet components over time. Effects of heat exposure may include: Reduced potency: Prolonged exposure to high temperatures can cause the medicine to degrade, so it may not work as well. Changes in tablet quality: Heat and humidity can affect the tablet’s appearance, hardness, or coating. Shorter shelf life: Storage outside Zhewitra 10 mg conditions may make the medicine expire sooner. For best storage: Keep it at room temperature (generally below 30°C). Store it in the original blister pack. Keep it away from direct sunlight, hot cars, bathrooms, and humid areas. A brief exposure to normal summer temperatures is usually less concerning than repeated or prolonged exposure to high heat. If you tell me how hot it got (approximate temperature), how long it was exposed, and whether the tablet changed color/appearance, I can help assess the risk.
