Persistent diarrhea, fever, or abdominal cramps should be evaluated promptly.","Kidney function should be checked before and during treatment, and the dose should be reduced in patients with kidney impairment.","This medicine does not cover Gram-positive bacteria or anaerobes, so additional antibiotics may be needed for mixed infections.","Prolonged use can lead to overgrowth of non-susceptible organisms, including fungi, and may require additional treatment.","Patients with phenylketonuria should be aware that some formulations of this medicine contain arginine, which is a source of phenylalanine.","This medicine should be used during pregnancy only when clearly needed, and breastfeeding mothers should discuss the risks and benefits with their doctor."]

🤱 Lactation Safety

This medicine is present in small amounts in breast milk. It is generally considered compatible with breastfeeding, but the amount that reaches the baby is low. Because the medicine is given in a hospital setting for serious infections, breastfeeding decisions should be made with the treating doctor, who may advise pumping and discarding milk during treatment or monitoring the baby for diarrhea or thrush.

Additional Safety Advice

If you are planning to become pregnant, discuss this medicine with your doctor before starting treatment. This medicine is generally used during pregnancy only when clearly needed, and the decision should be based on the severity of the infection and the available safety data. If you become pregnant while receiving this medicine, tell your doctor right away so that your treatment can be reviewed. Effective contraception is recommended during treatment if you are of childbearing potential and are not planning a pregnancy.

This medicine may be used after surgery to treat or prevent serious Gram-negative infections, especially after abdominal, gynecological, or urological procedures. The dose and duration depend on the type of surgery, the site of infection, and the patient's kidney function. After surgery, patients should be monitored for fever, wound discharge, pain, and signs of sepsis. The medicine is usually stopped when the infection is controlled and the surgical team confirms that there is no ongoing infection.

This medicine is not commonly used for routine dental procedures. If you are receiving this medicine for a serious infection and need dental work, tell your dentist about the medicine and your underlying condition. Dental procedures that cause bleeding may need to be postponed until your infection is controlled and your doctor says it is safe. Good oral hygiene and regular dental check-ups are important, but they do not replace the need for proper antibiotic treatment of a serious infection.

While receiving this medicine, you may feel tired, weak, or dizzy, especially if you have a fever or a serious infection. Avoid strenuous exercise, heavy lifting, and activities that could cause injury until your doctor says it is safe. Light activity such as short walks may be helpful once your fever settles, but you should not push yourself. If you feel chest pain, shortness of breath, or severe dizziness during any activity, stop and seek medical help.

This medicine is given intravenously in a hospital or clinic, so you will usually need to stay in the hospital or visit an infusion center for treatment. You should not drive yourself to and from infusions if you feel weak, dizzy, or feverish. Most people need time off work or school while they are receiving treatment for a serious infection. Once your fever settles and your doctor says you are stable, you may be able to return to light activities, but you should avoid operating heavy machinery or doing hazardous work until you feel fully well.

Do not stop this medicine on your own. Your doctor will decide when to stop based on your clinical improvement, culture results, and blood tests. In general, the medicine is stopped when the infection is controlled, the fever has settled, and repeat cultures show that the bacteria have cleared. If you develop a serious side effect such as a severe allergic reaction, kidney injury, or Clostridioides difficile infection, your doctor may stop the medicine and switch you to a different treatment. Always ask your doctor before stopping or changing the medicine.

This medicine is usually given for a limited time, such as 7 to 14 days, so long-term effects are uncommon. When used for longer periods, the main concerns are the development of antibiotic resistance, overgrowth of non-susceptible organisms such as fungi, and rare blood or liver abnormalities. Kidney function should be monitored in patients with kidney disease or those receiving other nephrotoxic drugs. If long-term therapy is needed, your doctor will review your cultures, blood counts, kidney function, and liver function regularly and will stop the medicine as soon as it is safe to do so.
