1. What is Tobramycin B. Braun and what is it used for

Tobramycin B. Braun belongs to a group of medicines called antibiotics, i.e. it is used to treat severe infections caused by bacteria that can be killed by the active substance - tobramycin.
The patient may receive tobramycin to treat the following diseases:

• hospital-acquired infections of the lungs and lower respiratory tract;
• infections of the lungs and lower respiratory tract in patients with cystic fibrosis;
• complicated and recurrent infections of the kidneys, urinary tract, and bladder;
• infections within the abdominal cavity;
• skin and soft tissue infections, including severe burns. If necessary, therapy may also include other antibiotics.

When not to use Tobramycin B. Braun

Warnings and precautions

Before starting treatment with Tobramycin B. Braun 1 mg/ml or 3 mg/ml, the patient should discuss it with their doctor or pharmacist.
Particular caution should be exercised if

• the patient has kidney disease,
• the patient has hearing disorders or any inner ear abnormalities,
• the patient has Parkinson's disease,
• if the patient or their family members have a disease associated with mitochondrial mutation (a disease caused by variants of mitochondrial genomes, parts of cells involved in energy production) or hearing loss caused by antibiotic drugs; some mitochondrial mutations may increase the risk of hearing loss after using this medicine.

If the patient has any of the above diseases, they should inform their doctor.
Tobramycin may have a harmful effect on the kidneys and the auditory nerve, so the patient will be closely monitored for any symptoms that may indicate such damage during treatment.
Monitoring of kidney function, hearing, and balance is particularly important when the patient already has

• or may have - kidney function disorders or when kidney function worsens during treatment.

Avoid using tobramycin with rapidly acting diuretics or other medicines that may also damage the kidneys and the auditory nerve.
Monitoring will include

• kidney function, especially if the patient is elderly or has impaired kidney function,
• hearing,
• tobramycin concentration in the blood, as often as possible.

If symptoms of kidney function impairment or worsening of kidney function occur, the daily doses will be reduced and (or) the interval between doses will be extended. If kidney function disorders become severe, therapy will be discontinued. Tobramycin treatment will also be discontinued if there is damage to the auditory nerve, manifested by tinnitus or hearing loss.
If the patient experiences severe diarrhea, they should immediately inform their doctor.
If muscle blockage occurs, it can be treated with calcium salts.
During treatment, fluid and electrolyte levels will be monitored.
If the patient has extensive burn wounds, tobramycin concentration in the blood will be closely monitored.
If the patient is undergoing surgical procedures involving irrigation of wounds with solutions containing tobramycin or other aminoglycosides, this will be taken into account when determining the tobramycin dose.
Particular caution should be exercised if the patient is elderly.
Children
In premature and full-term newborns, tobramycin will be administered with particular caution.

Tobramycin B. Braun and other medicines

The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
Attention should be paid to the following medicines.

Muscle relaxants, ether, citrated blood:
They may increase the risk of nerve or muscle blockage. Such a combination will be avoided whenever possible.
Methoxyflurane anesthesia
The patient should inform the anesthesiologist before undergoing methoxyflurane anesthesia (an anesthetic gas) that they have taken or are taking aminoglycosides, and methoxyflurane should be avoided whenever possible due to the increased risk of kidney damage.
Other medicines that may also damage the kidneys and the auditory nerve
The harmful effect of tobramycin on the kidneys and the auditory nerve may be enhanced by:

• other substances used to treat infections, such as amphotericin B, polymyxin B, colistin, cephalothin, aminoglycosides;
• cisplatin (an anticancer drug - in this case, kidney damage may occur even three to four weeks after administration of these medicines);
• cyclosporine, tacrolimus (a substance that suppresses undesirable immune reactions);
• rapidly acting diuretics: furosemide or ethacrynic acid. Whenever possible, these medicines should not be administered simultaneously with tobramycin or after using tobramycin.

Other antibiotics
Combination therapy with appropriate antibiotics (e.g. beta-lactams) may significantly enhance the therapeutic effect. However, the effect of tobramycin is weakened by antibiotics similar to penicillin if the patient has severe kidney function disorders.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor before using this medicine.
Pregnancy
If the patient is pregnant, the doctor will prescribe this medicine only if it is absolutely necessary.
Breastfeeding
Although tobramycin is not usually absorbed in the intestines of breastfed children, the doctor will carefully consider whether to discontinue breastfeeding or tobramycin treatment.

Driving and using machines

Caution is recommended when driving vehicles and operating machines due to possible side effects such as dizziness.

Tobramycin B. Braun, 3 mg/ml
The medicine contains 283 mg of sodium (the main component of common salt) in each 80 ml vial. This corresponds to 14.2% of the maximum recommended daily sodium intake in the diet for adults.
The medicine contains 425 mg of sodium (the main component of common salt) in each 120 ml vial. This corresponds to 21.3% of the maximum recommended daily sodium intake in the diet for adults.

3. How to use Tobramycin B. Braun

Tobramycin B. Braun is administered by intravenous infusion directly into a vein.
The recommended administration time for the contents of one vial is 30 minutes, but it may be extended to 60 minutes.
The doctor will determine the appropriate dose for the individual patient.
The following are the usual doses used.

Dosing in patients with normal kidney function

Adults and adolescents
Severe infections
3 mg of tobramycin per kg of body weight (bw) per day in one dose or 1 mg/kg bw in divided doses administered every 8 hours.
Life-threatening infections
Up to 5 mg of tobramycin per kg of body weight (bw) per day in one dose or 1.66 mg/kg bw in divided doses administered every 8 hours (or 1.25 mg/kg bw every 6 hours). As soon as the patient's clinical condition improves, the dose should be reduced.
Cystic fibrosis
Up to 8-10 mg of tobramycin per kg of body weight (bw) per day in divided doses.
Newborns and children over 1 week of age:
From 6 to 7.5 mg of tobramycin per kg of body weight (bw) per day in one dose or 2 to 2.5 mg/kg bw every 8 hours, or 1.5 to 1.9 mg/kg bw every 6 hours.
The dose and vial size the patient receives will depend on their body weight. The doctor or nurse will ensure that the volume administered to the patient does not exceed the recommended dose. It is essential to ensure that the patient receives the correct dose.
The daily dose of tobramycin may be administered as a single dose
This does not apply to patients with impaired immunity, kidney failure, a history of or symptoms indicating hearing loss, ascites, extensive burns (over 20% of the skin surface), and pregnant women. Patients with normal kidney function will receive 5 mg/kg body weight in a single daily dose.

Dosing in patients with kidney function disorders

If the patient has kidney function disorders, tobramycin concentration in the blood and kidney function will be carefully and frequently monitored to adjust the tobramycin dose accordingly. The doctor knows how to calculate and adjust the doses the patient should receive.
If the patient is undergoing hemodialysis or peritoneal dialysis, the dose will be carefully selected based on the tobramycin concentration in the blood.

Patients with significant overweight

In these patients, the dose is calculated based on the estimated ideal body weight plus 40% of excess body weight.

Duration of treatment

Tobramycin treatment usually lasts 7-10 days. Longer treatment may be necessary in cases of severe and complicated infections. Kidney function, hearing, and balance will be monitored.

Using a higher dose of Tobramycin B. Braun than recommended

Overdose may lead to kidney damage and hearing nerve damage or muscle blockage (paralysis). In such cases, tobramycin infusion should be discontinued. In patients with normal kidney function, the doctor will ensure that there is proper urine excretion. Tobramycin excretion can be forced by dialysis. Muscle blockage can be treated with calcium salts. If respiratory paralysis occurs, respiratory support may be necessary.
If an acute allergic reaction occurs, emergency measures should be taken.
In case of any further doubts about the use of this medicine, the patient should consult their doctor.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
In this leaflet, the frequency of side effects is defined as follows:
Very common:
occurs in more than 1 in 10 patients treated;
Common:
occurs in 1 to 10 in 100 patients treated;
