What is tobramycin?
Tobramycin is an aminoglycoside (ah-meen-oh-GLY-ko-side) antibiotic. Tobramycin fights infections that are caused by bacteria.
Tobramycin inhalation is inhaled into the lungs using a nebulizer. Tobramycin inhalation is used to treat lung infections in patients with cystic fibrosis.
Tobramycin inhalation is for use in adults and children who are at least 6 years old.
Tobramycin inhalation may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Before taking this medicine
To make sure tobramycin is safe for you, tell your doctor if you have ever had:
breathing problems (cough, wheezing, chest tightness);
an organ transplant;
Do not use tobramycin if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment.
It is not known whether tobramycin passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
How should I use tobramycin?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Tobramycin is inhaled into the lungs with the use of a nebulizer or an inhaler device. Do not swallow the medicine by mouth.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Tobramycin is given in a treatment cycle of 28 days on the medicine followed by 28 days off the medicine. Follow your doctor's dosing instructions very carefully. Your doctor will determine how long to treat you with tobramycin.
During your 28 days on the medicine, use your doses at regular intervals of 12 hours apart but not less than 6 hours apart.
If you use other inhaled medicines, or if you perform chest physiotherapy to remove mucus from the lungs, use these other treatments first before using your tobramycin dose.
Do not use tobramycin inhalation solution if it looks cloudy or has particles in it. Call your pharmacist for new medicine.
Tobi Podhaler is a powder form of tobramycin that comes with a special inhaler device and blister packs containing capsules of the medicine. You will load one capsule into the inhaler device each time you use the medicine. Pushing the buttons on the end of the Podhaler device will pierce the capsule and release the medicine into the inhaler chamber. Use only the capsules provided with the Tobi Podhaler device.
Store tobramycin ampules in the refrigerator between 36 and 46 degrees Fahrenheit (2 and 8 degrees Celsius).
If refrigeration is not available, store the ampules at cool room temperature for up to 28 days. Protect from light. The solution may become darker in color at room temperature, but this should not affect the quality of the medicine. Throw away any ampules not used before the expiration date on the label.
Store tobramycin capsules in their blister pack at room temperature away, from moisture and heat. Remove only one capsule at a time and only when you are ready to use it.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 6 hours away. Do not use extra medicine to make up the missed dose.
