How should I take Garamycin?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended. Garamycin is usually given for 7 to 10 days.
Garamycin is injected into a muscle, or into a vein through an IV. You may be shown how to use an IV at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.
