1. What is Streptomycin Reig Jofre and what is it used for

Streptomycin Reig Jofre is an antibiotic belonging to the group of aminoglycosides, used to treat serious infections caused by bacteria.

Streptomycin Reig Jofre is used in adults and children to treat the following infections:

• Multidrug-resistant tuberculosis (in combination with other anti-tuberculosis medications)
• Brucellosis (in combination with other antibiotics), also known as Malta fever.
• Plague
• Tularemia, an infection caused by contact with infected animals (mainly rabbits and hares)
• In combination with other antibiotics, to treat endocarditis (inflammation of the inner lining of the heart) caused by bacteria called enterococci.

2. What you need to know before you start taking Streptomycin Reig Jofre

• If you are allergic to streptomycin, aminoglycosides, or any of the other components of this medicine (listed in section 6).

Warnings and Precautions

Consult your doctor, pharmacist, or nurse before starting to use Streptomycin Reig Jofre if:

• you have a disease that affects nerve and muscle function, such as myasthenia gravis

or Parkinson's disease

• you do not urinate regularly
• you are dehydrated
• you are receiving treatment for kidney problems
• you have inner ear deafness
• you are taking other antibiotics
• you are pregnant or breastfeeding

In these cases, you will receive streptomycin only if your doctor considers it essential for the treatment of your disease. Your doctor will be especially careful when adjusting your streptomycin dose correctly.

Your doctor will be especially careful if you have a disease that affects nerve and muscle function, such as Parkinson's disease or myasthenia gravis, or if you receive a muscle relaxant during an operation, since streptomycin can have a blocking effect on nerve and muscle function.

It is possible that your infection will not respond to streptomycin if you did not respond to other antibiotics in the aminoglycoside group. It is also possible that you will develop an allergic reaction to streptomycin if you are already allergic to another aminoglycoside.

To reduce the risk of nerve damage to the ear and kidney, your doctor will be especially careful when evaluating the following:

• Monitoring of hearing, balance, and kidney function before, during, and after treatment.
• Dose adjustment according to the degree of kidney function.
• Monitoring of streptomycin levels in the blood during treatment if necessary.
• If you already have nerve damage in the ear (hearing loss or balance problems) or if the treatment is long-term, additional monitoring of balance and hearing function is required.
• Avoiding the administration of other substances with potential harmful effects on the auditory nerve or kidneys in combination with streptomycin. If this is unavoidable, careful monitoring of kidney function is required.
• The level of body fluids and urine production should be within the normal range.

Interference with analytical tests:

Streptomycin may cause alterations in blood or urine analysis values of certain substances such as urea, transaminases, alkaline phosphatase, bilirubin, creatinine, lactate dehydrogenase, sodium, potassium, magnesium, and calcium.

Other Medicines and Streptomycin Reig Jofre

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

The simultaneous or sequential use of Streptomycin Reig Jofre with other medicines that may affect the kidneys or the nervous system (cisplatin, cyclosporin, neomycin, kanamycin, gentamicin, tobramycin, amikacin, netilmicin, paromomycin, capreomycin, amphotericin B, polymyxin B, colistin, vancomycin) should be avoided.

It should not be administered simultaneously or immediately after anesthesia or muscle relaxants.

Aminoglycosides, including streptomycin, may cause toxic effects on the ear, which can be potentiated by the administration of medications such as furosemide, mannitol, and possibly other diuretics.

There is a risk of masking signs of vestibular toxicity (related to balance and spatial control) with medications for treating vertigo.

Tell your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription and herbal medicines.
