Dalbavancin is given through an IV infusion. Here’s how it is typically used:

• IV Infusion: Dalbavancin is injected directly into a vein. The infusion usually lasts about 30 minutes, though the exact time may vary based on the patient and the specific protocol used.
• Treatment Schedule: For skin and soft tissue infections, Dalbavancin is often given in two doses—one initial dose of 1,000 mg, followed by a second 500 mg dose one week later. Your doctor will determine the exact schedule depending on your infection.
• Hospital or Home Use: Typically, Dalbavancin is administered in a hospital or clinic, but in some cases, it may be given at home if the patient is stable and has access to an appropriate infusion setup.

Follow your healthcare provider’s instructions carefully to ensure you receive the correct dosage and treatment plan. Do not adjust the dose or stop treatment without consulting your doctor.

Dalbavancin works by interfering with the ability of bacteria to build their cell walls. The cell wall is a crucial part of a bacterium’s structure and function, and without it, the bacteria cannot survive or multiply. Here’s how it works:

• Inhibits Cell Wall Synthesis: Dalbavancin binds to specific proteins on the surface of the bacteria, preventing them from making their cell walls. Without a functioning cell wall, bacteria are unable to protect themselves from external pressures and ultimately die.
• Targeting Gram-positive Bacteria: Dalbavancin is particularly effective against gram-positive bacteria, which are the types of bacteria that cause many serious infections, including those of the skin, soft tissues, and bloodstream.

This mechanism of action makes Dalbavancin a useful option for treating infections caused by bacteria that have become resistant to other antibiotics.

Dalbavancin is generally well-tolerated, but like all medications, it can cause side effects. Some common side effects include:

• Nausea: Some people may experience mild stomach discomfort or nausea after receiving Dalbavancin.
• Headache: Headaches are a possible side effect of the medication.
• Diarrhea: Some patients may develop mild digestive issues, including diarrhea, while taking Dalbavancin.
• Skin Reactions: Since Dalbavancin is administered intravenously, some patients may experience redness, swelling, or pain at the injection site.

Serious side effects are rare but can include:

• Kidney Issues: Dalbavancin can affect kidney function, especially if used in high doses or if the patient has pre-existing kidney problems. Symptoms of kidney problems may include changes in urination, swelling in the feet or ankles, or feeling very tired.
• Severe Allergic Reactions: Though rare, Dalbavancin can cause serious allergic reactions. Symptoms may include difficulty breathing, rash, swelling of the face or throat, and dizziness. Seek immediate medical attention if you experience any of these symptoms.

If you notice any unusual or severe side effects, contact your healthcare provider immediately.

Before using Dalbavancin, there are several important warnings and precautions:

• Kidney Function: Dalbavancin can affect kidney function. Your doctor will monitor your kidney function before and during treatment, especially if you have pre-existing kidney conditions.
• Allergic Reactions: If you are allergic to any glycopeptide antibiotics (like vancomycin), inform your doctor before taking Dalbavancin, as there may be a risk of an allergic reaction.
• Pregnancy and Breastfeeding: The safety of Dalbavancin during pregnancy and breastfeeding has not been fully established. If you are pregnant, planning to become pregnant, or breastfeeding, speak to your doctor about the risks and benefits before starting treatment.
• Other Health Conditions: Inform your doctor of any other health conditions, particularly if you have heart problems, liver disease, or other infections.

Dalbavancin can interact with other medications, so it’s essential to inform your healthcare provider about all drugs you are taking. Some important interactions include:

• Other Antibiotics: Taking Dalbavancin with certain other antibiotics may increase the risk of side effects. This includes antibiotics like aminoglycosides (e.g., gentamicin or tobramycin), which are also used to treat bacterial infections.
• Blood Thinners: Dalbavancin may interact with blood-thinning medications, such as warfarin. If you are taking a blood thinner, your doctor may monitor your blood clotting levels closely while you are receiving Dalbavancin.
• Medications Affecting the Kidneys: Dalbavancin can affect kidney function, and it may interact with other medications that can also affect the kidneys. If you are taking drugs that are processed through the kidneys, your healthcare provider will monitor you carefully for signs of kidney problems.

Always inform your doctor about any medications, including over-the-counter drugs and supplements, to prevent harmful interactions.

Dalbavancin is typically administered as an intravenous infusion, with the following guidelines:

• For Skin and Soft Tissue Infections: The usual dose is 1,000 mg initially, followed by 500 mg one week later.
• For Other Infections: The exact dose and frequency may vary depending on the infection being treated, so follow your doctor’s recommendations carefully.

Dalbavancin is available only by prescription, so you will need to see a healthcare provider for a diagnosis and treatment plan. If you have been prescribed Dalbavancin, your doctor will ensure it is the right treatment for your infection and will guide you through the administration process.
