What Is Vancomycin?
Simply put, vancomycin is an antibiotic medicine. However, this is not the typical antibiotic you might take for a routine cold or throat infection. It belongs to a special class of medicines known as glycopeptides.
The main job of this medicine is to control and treat specific, severe bacterial infections that develop inside your digestive tract. Think about what happens when you take other broad-spectrum antibiotics. Sometimes, those medicines wipe out the helpful bacteria living in your gut. When that happens, harmful bacteria such as Clostridium difficile can grow rapidly out of control.
This overgrowth leads to serious problems like severe watery diarrhea, intense stomach cramps, and general physical distress. Doctors prescribe vancomycin oral solution specifically to target and clear up these difficult gut infections.
The most important thing to remember is that this medicine cannot cure viral infections. It has zero effect on colds, fevers, or the flu because it only works against bacteria.
Things to Tell Your Doctor Before Taking This Medicine
Before you start taking vancomycin, sharing a complete picture of your medical history with your doctor is essential. Your doctor makes treatment decisions based on these vital details to ensure the medicine is safe and appropriate for you.
Make sure to tell your doctor right away if you have any of the following health conditions or circumstances:
- Any history of kidney disease or kidney problems, because your body filters this medicine out mainly through your kidneys.
- Other chronic bowel conditions, such as inflammatory bowel disease (IBD).
- Signs of dehydration, meaning your body lacks enough fluids.
- If you are currently pregnant, planning to become pregnant soon, or breastfeeding a baby.
- Any past allergic reactions to vancomycin, other antibiotics, specific foods, or dyes.

This medicine comes as an oral liquid solution that you swallow. Keep these practical daily usage steps in mind:
- Follow medical directions closely: Take the exact dose your doctor prescribed at the exact times requested. Never skip doses or change your schedule on your own.
- Shake well before use: Always shake the medicine bottle thoroughly right before measuring out your dose.
- Use the correct measuring tool: Always use the specially marked oral syringe or dosing spoon that comes with your prescription. Regular kitchen teaspoons or tablespoons do not measure accurate medical doses.
- Complete your full course: Even if your symptoms disappear and you feel completely healthy, finish every dose for the full number of days your doctor ordered. Stopping early allows the infection to return stronger.
- Giving it to children: If you are giving this medicine to a child, consult a pediatrician first for precise weight-based dosing guidance.
What to Do If You Take Too Much
If you suspect that you or someone else has taken too much of this medicine, seek medical help right away. Go straight to the nearest hospital emergency department (ER or A&E). In the US or Canada, call 911. In the UK, call 999. You can also contact your local poison control center for urgent guidance.
Side Effects and What to Watch For
Like all medicines, vancomycin can cause side effects in some people. While many people tolerate it well, knowing what warning signs require attention is important.
| Side Effect Category | Description & Action Needed |
|---|---|
| Serious Allergic Reactions | Skin rashes, hives, severe itching, or swelling of your face, lips, tongue, or throat. Seek emergency care right away. |
| Breathing Difficulties | Trouble breathing, wheezing, or a tight feeling in your chest. Call emergency services right away. |
| Kidney Function Changes | Sudden changes in how often you urinate, changes in urine color, or swelling in your feet and ankles. Contact your doctor promptly. |
| Hearing Changes | New or worsening ringing in your ears (tinnitus) or any temporary loss of hearing. Tell your doctor right away. |
| Severe Skin Reactions | Red or purple skin blisters, peeling skin, painful sores inside your mouth, or swollen lymph nodes. Seek immediate medical evaluation. |
| Common Mild Effects | Mild nausea, occasional vomiting, or mild stomach upset. Contact your doctor if these symptoms persist or bother you. |
Other Medicines That May Interact with Vancomycin
Always tell your doctor and pharmacist about every prescription drug, over-the-counter medicine, vitamin supplement, or herbal product you take. Certain products can interact with vancomycin and alter how it works:
- Cholestyramine and colestipol: These cholesterol-lowering medicines bind to substances in your gut and can prevent your body from absorbing vancomycin properly. If you take one of these medicines, separate your doses by waiting at least 3 to 4 hours after taking your vancomycin dose.
- Birth control pills: Some antibiotics can lower the reliability of hormonal birth control pills. Discuss backup birth control options with your doctor during your treatment.
- Injectable vancomycin: If you are receiving vancomycin through an intravenous (IV) injection at the same time, your care team must monitor your blood levels carefully.
When to Seek Emergency Medical Attention
Go to the nearest hospital emergency department or call emergency services (911 in the US/Canada, 999 in the UK) right away if you experience signs of a severe allergic reaction, trouble breathing, sudden swelling of the face or throat, severe blistering skin rashes, or extreme dizziness.
How to Store Your Medicine Properly
Once your pharmacist prepares your liquid vancomycin solution, you must store it safely in your refrigerator. Keep the bottle at a cool temperature between 2°C and 8°C (36°F to 46°F).
Never place this liquid medicine in your freezer. If the solution freezes, it spoils and becomes unsafe to use.
Always check expiration guidelines carefully. Discard any remaining medicine after 14 days, as it is no longer potent or safe to eat. As with all medicines, keep vancomycin safely out of the reach of children and pets.
