HOW TO USE NTG:
NTG: Transdermal skin patches are to be applied to a clean, hairless area on the upper arm or chest not subject to excessive movement. The patch should remain in place while bathing or showering. Remove the previous patch before applying a new one. Apply the new patch to a different area to minimize skin irritation by using a new area of skin. The patch is usually worn for 12 to 14 hours a day and then a new patch put on 10 to 12 hours later or as directed. NTG-free period improves the drug's effectiveness. Do not stop using NTG suddenly without consulting your doctor. Some conditions may worsen when the medication is suddenly stopped. Your dose may need to be gradually decreased.
Nitroglycerin relaxes blood vessels allowing more blood to flow through and improves blood flow to the heart. Topical nitroglycerin skin patches are used to prevent angina (chest pain). NTG is NOT for treating an attack of chest pain that has already started.
Before using NTG tell your doctor your medical history especially of: heart problems, head injury or surgery, glaucoma, thyroid conditions, anemia, alcohol usage, allergies (especially allergies to drugs or adhesives). Use caution engaging in activities that require alertness or in operating machinery if NTG makes you dizzy or drowsy. Alcoholic beverages may increase the risk of fainting or of experiencing dizziness. NTG should be used during pregnancy only if clearly needed. Discuss the risks and benefits with your doctor. It is not known if NTG is excreted into breast milk. Consult your doctor before breast-feeding.
