Indications 

Nitroglycerin is prescribed to prevent angina pectoris in coronary artery disease. It relaxes and widens blood vessels to improve blood flow to the heart muscle. This is not for relieving acute chest pain or immediate use before physical activity. Consult a healthcare professional for appropriate management in these situations. 

Uses and Dosage 

Administer the patch by carefully extracting it from the pouch and following the prescribed instructions to remove the protective clear liner. Typically, the patch is to be affixed to the upper arm or chest region; however, it can be applied to any area below the neck and above the knees or elbows on the body. Ensure the selected size is clean, dry, and devoid of hair.  

Trimming hair in the application area is acceptable, but shaving is not recommended. Avoid application to regions with cuts or skin irritation. Refrain from applying the patch immediately after bathing or showering; wait until the skin is thoroughly dry. Notably, you can enjoy bathing, showering, and swimming while wearing the patch. Press the patch firmly onto the chosen location using the palm of your hand, and remember to wash your hands after application. 

Adhere to the prescribed usage guidelines as provided by your healthcare professional, which typically involves the application of one patch daily, worn for 12 to 14 hours. The specific dosage is contingent upon your medical condition and your response to treatment. 

Apply each new patch to a different skin area to mitigate potential skin irritation. Upon removing the used patch, fold it in half with the adhesive sides facing each other and dispose of it in a manner inaccessible to children and pets. 

Consistency in medication use is pivotal to derive optimal therapeutic benefits. To facilitate adherence, administer the patch at the same time each day.
