🇮🇳 allegra 180mg tablet के बारे में (Hindi Summary)
उपयोग: यह दवा एलर्जी से होने वाले लक्षणों जैसे छींक आना, नाक बहना, आंखों में खुजली और पानी आना, और त्वचा पर पित्ती उठना आदि के इलाज में इस्तेमाल की जाती है। यह मौसमी एलर्जी और पुरानी पित्ती के लिए प्रभावी है। यह दवा हिस्टामिन नामक पदार्थ को रोककर काम करती है, जिससे एलर्जी के लक्षण कम होते हैं। यह दवा आमतौर पर दिन में एक बार ली जाती है और इससे नींद कम आती है।
साइड इफेक्ट्स: इस दवा के आम दुष्प्रभावों में सिरदर्द, नींद आना, चक्कर आना, जी मिचलाना और महिलाओं में मासिक धर्म के दर्द शामिल हैं। ये आमतौर पर हल्के होते हैं और अपने आप ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन दिल की धड़कन तेज होना, गंभीर एलर्जी या लीवर की समस्या हो सकती है। अगर कोई असामान्य लक्षण दिखे तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। अपनी मर्जी से ज्यादा मात्रा में न लें। इस दवा के साथ अंगूर का जूस न पिएं, क्योंकि इससे दवा का असर बढ़ सकता है। अगर आपको किडनी की बीमारी है तो डॉक्टर को बताएं, क्योंकि आपको कम मात्रा की जरूरत हो सकती है। इस दवा से कुछ लोगों को नींद आ सकती है, इसलिए जब तक आपको इसका असर पता न चले, गाड़ी न चलाएं। बच्चों की पहुंच से दूर रखें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively blocking histamine H1 receptors in the body. Histamine is a chemical released during allergic reactions, and it causes symptoms such as sneezing, itching, and runny nose. By blocking these receptors, this medicine prevents histamine from causing these symptoms. It is a second-generation antihistamine, which means it is less likely to cause drowsiness compared to older antihistamines.
