साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में चक्कर आना, सिरदर्द, बार-बार पेशाब आना और प्यास लगना शामिल हैं। कुछ लोगों को पेट खराब, जी मिचलाना या उल्टी हो सकती है। गंभीर दुष्प्रभावों में पोटैशियम का स्तर कम होना, जिससे मांसपेशियों में कमजोरी या ऐंठन हो सकती है, और सोडियम का स्तर कम होना शामिल है। यदि आपको गंभीर पेट दर्द, सांस लेने में कठिनाई, चेहरे या गले में सूजन, या त्वचा पर चकत्ते दिखें तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को अपने डॉक्टर के बताए अनुसार ही लें। दवा की खुराक बदलें या बंद करने से पहले डॉक्टर से सलाह लें। इसे आमतौर पर सुबह लें ताकि रात में बार-बार पेशाब न आए। पर्याप्त पानी पिएं जब तक डॉक्टर कुछ और न कहें। शराब से बचें क्योंकि इससे चक्कर और निम्न रक्तचाप बढ़ सकता है। अचानक उठने पर धीरे-धीरे उठें। अपने डॉक्टर को गुर्दे, लीवर, मधुमेह, गाउट या लूपस की जानकारी दें। अन्य दवाओं के बारे में भी बताएं। गर्भावस्था या स्तनपान के दौरान डॉक्टर से परामर्श करें। नियमित जांच कराते रहें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by inhibiting the sodium-chloride symporter in the distal convoluted tubule of the kidney. This action prevents the reabsorption of sodium and chloride, leading to increased excretion of water, sodium, chloride, and potassium. The loss of fluid reduces blood volume and cardiac output initially, and over time, it lowers peripheral vascular resistance. The exact mechanism of blood pressure reduction during long-term use is not fully understood but is thought to involve a reduction in vascular smooth muscle tone and changes in sodium balance.

Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and response to therapy. |
