Scopolamine gel, often administered as a transdermal patch, is a medication used to prevent certain types of nausea and vomiting. It belongs to a class of drugs called anticholinergics, which work by affecting specific chemical messengers in the brain. This medication is designed for absorption through the skin, providing a sustained release of the active compound into the bloodstream.
What Scopolamine Gel Is Used For
Scopolamine gel is primarily prescribed to prevent nausea and vomiting associated with motion sickness. It is also used to prevent postoperative nausea and vomiting (PONV), which can occur after anesthesia and surgical procedures. The medication works by blocking the action of acetylcholine, a neurotransmitter involved in transmitting signals between nerve cells. This helps to calm the muscles in the stomach and bowels, reducing the signals that trigger vomiting. This mechanism also makes it effective in managing symptoms like vertigo and dizziness that can arise from inner ear disorders.
How to Properly Apply Scopolamine Gel
Applying the scopolamine transdermal patch correctly is important for its effectiveness and to reduce the risk of side effects. The patch should be applied to a clean, dry, hairless area of skin behind the ear. Before application, ensure your hands and the skin area are free of lotions, oils, or makeup, as these can interfere with adhesion and absorption. After opening the pouch, peel off the clear protective backing, being careful not to touch the adhesive side.
Place the adhesive side of the patch firmly onto the skin behind the ear, pressing it down to ensure good contact. The patch is designed to deliver medication consistently for up to three days. Wash your hands thoroughly with soap and water immediately after applying the patch to prevent any medication from accidentally getting into your eyes or other mucous membranes. If the patch detaches, a new one can be applied to a different area behind the other ear.
Important Considerations and Potential Side Effects
Scopolamine gel can cause various side effects, with dry mouth, drowsiness, and blurred vision being among the most common. Other potential effects include dizziness, disorientation, and confusion. If the medication comes into contact with the eyes, it can temporarily dilate pupils and cause blurry vision. Patients should avoid activities requiring alertness, such as driving, until they understand how the medication affects them.
Individuals with glaucoma or urinary retention may experience worsened conditions. Scopolamine can interact with other medications, especially those that cause drowsiness, increasing the risk of adverse effects. If the patch is used for longer than three days, withdrawal symptoms like dizziness, nausea, and vomiting may occur upon removal. Always consult a healthcare professional before using scopolamine gel, especially if you have pre-existing medical conditions or are taking other medications.
