What is Eravacycline?

Simply put, Eravacycline belongs to a family of antibiotics called tetracyclines. Doctors use this specific medicine to treat serious bacterial infections in different parts of the body.

The most important thing to remember is that this medicine only works against bacteria. It will not help treat viral infections like a common cold or the flu. For this reason, you should only use Eravacycline when a doctor prescribes it for you.

Most of the time, you will receive this medicine while you are in the hospital. A nurse or doctor will give it to you slowly through an intravenous (IV) infusion into your vein.

Things to Tell Your Doctor Before Taking This Medicine

Before your doctor decides to give you Eravacycline, they will ask you several health questions. Giving accurate answers is very important for your safety and well-being.

Medical Condition or Situation Why Your Doctor Needs to Know
Liver disease Your liver helps process and clear medicines from your body. If your liver is weak, your doctor may need to adjust your dose.
Allergies Tell your doctor if you are allergic to Eravacycline, other tetracycline medicines, or any foods, dyes, or other drugs.
Pregnancy Medicines in this class can sometimes affect an unborn baby. Always discuss this with your doctor if you are pregnant or planning a family.
Breastfeeding Small amounts of the medicine may pass into breast milk. Your doctor will help you decide if it is safe to continue nursing.

How is This Medicine Used?

You will usually receive Eravacycline in a hospital or clinic setting. A trained doctor will give it to you as an infusion directly into a vein.

In rare cases, you might receive instructions to continue treatment at home. If that happens, your care team will give you detailed training on how to prepare and take it safely. Always take the exact dose at the exact time your doctor tells you to. Never take more than your doctor prescribes.

What to Do With Used Needles

If you are giving yourself this treatment at home, never throw used needles and syringes into a normal household trash bin. Used needles are very dangerous. You must place them into a special hard plastic container known as a sharps container. If you do not have one, ask your doctor or pharmacist where to get one safely.

Giving This Medicine to Children

Using Eravacycline in children requires special medical attention and caution. Because of this, you must always consult a pediatrician and follow their expert advice closely.

What to Do If You Take Too Much

If you feel that you or someone else received too much of this medicine by mistake, do not panic. Take action right away to stay safe.

Go right away to the nearest hospital Emergency Department (ER). If you are in the US or Canada, call 911. If you are in the UK, call 999 or go to your local Accident and Emergency department right away for professional medical help.

Other Medicines That May Intersect With Eravacycline

Other Important Things to Watch While Taking This Medicine

  • Watch your symptoms: If your infection does not get better, or if it feels like it is getting worse, contact your doctor right away.

  • Severe allergic reactions: Skin rash, severe itching, swelling of your face, lips, tongue, or trouble breathing.
  • Severe diarrhea: Frequent watery stools or stools containing blood or mucus.
