What should I know about Avelox before taking it?

If you are allergic to other antibiotics, let your doctor know before you take Avelox. Also, let your doctor know if you have liver or kidney disease, joint problems, diabetes, myasthenia gravis, reoccurring seizures, a low blood potassium level (hypokalemia), or if you or a family member have "Long QT syndrome.” Do not take antacids, vitamins and mineral supplements, sucralfate (Carafate), or didanosine (Videx) for eight hours prior to or four hours after taking Avelox. Avelox may not work as well if taken with these medicines. You may be more likely to get sunburn while on Avelox, so use caution when going out in the sun or using tanning beds. Some cases of nerve damage have been reported in people taking similar drugs, leading to pain, numbness, tingling or weakness, which is sometimes irreversible. Avelox can affect your blood sugar, causing it to become either too high or too low. Diabetics should watch their blood glucose closely while taking Avelox.
