INOBASE (OXYTROL) INSTRUCTIONS
Use Inobase exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Inobase comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
To use the Inobase patch, open the sealed pouch and remove the protective liner. Apply the transdermal patch to a clean, dry area on your stomach, hip or buttock. Avoid skin that is oily, irritated, or damaged. Avoid placing the patch on a skin area that will be rubbed by a waistband or tight clothing.
Press the Inobase patch onto the skin and press it down firmly with your fingers. Make sure the patch is well sealed around the edges. When properly applied, the patch should stay on while swimming or bathing.
Leave the Inobase patch in place and wear it for 3 to 4 days. You should change the patch twice per week. Each time you apply a new patch, choose a different skin area on your stomach, hip, or buttock. Do not apply a patch to the same skin twice within one week.
Try to change your Inobase patch on the same two days each week (such as every Sunday and Thursday). There is a calendar printed on the package of this medication to help you establish a steady patch-changing schedule.
If the patch falls off, try sticking it back on. If it does not stay on, replace it with a new one and wear it until your next regular patch-changing day. Do not change your schedule, even if you apply a new patch to replace one that has fallen off.
After removing an Inobase patch, fold it in half so it sticks together and throw it away in a place where children or pets cannot get to it.
Use baby oil or mild soap and water to remove any adhesive residue that stays on your skin. Avoid using harsh soaps, alcohol, nail polish remover, or other solvents that could irritate your skin.
The Inobase patch may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test. Keep the Inobase patch in its sealed pouch until you are ready to use it.
