Glycopyrrolate

Description

Glycopyrrolate is used as a general anaesthetic. It is also used in the treatment of chronic obstructive pulmonary disease (a respiratory condition that causes blockage of airflow to your lungs) and gastric ulcers (soreness or damage in the inner lining of your stomach and intestine). It also reduces drooling in children due to certain conditions. It works by controlling the excess production of saliva, stomach acid, and secretions in your windpipe and lungs. Glycopyrrolate shows some side effects like tiredness, stuffy nose, decreased sweating, dry mouth, and constipation. Consult your doctor if any side effects persist or worsen. Glycopyrrolate should be taken as instructed by your doctor. The dose and frequency of intake will be decided by your doctor depending on your clinical condition. Take it every day at the same time for better results. You should never take more than the prescribed dose as it leads to undesired effects. Inhaling capsules should be taken using a rotahaler and should be changed every six months. You should take respules using nebulizers. Injections should only be taken in a hospital setting by qualified healthcare professionals. Glycopyrrolate is not recommended if you are allergic to it. Inform your doctor if you have any medical conditions, or are taking any other medications. Consult your doctor if you are pregnant or are breastfeeding before taking Glycopyrrolate.
