Tigecycline is used to treat certain serious bacterial infections when other antibiotics may not work. It is related to a class of drugs known as tetracycline antibiotics. It works by stopping the growth of bacteria.

Read the Patient Information Leaflet if available from your pharmacist before you start using tigecycline and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is given by injection into a vein over 30 to 60 minutes by a healthcare professional. It is given as directed by your doctor, usually every 12 hours. The dosage is based on your medical condition and response to treatment.

If you are using this medication at home, learn all preparation and usage instructions from your health care professional. Swirl the medication gently to mix. Do not shake. The mixed medication should be yellow to orange in color. Before using, check this product for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

For the best effect, use this antibiotic at evenly spaced times. To help you remember, use this medication at the same times every day.

Continue to use this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.

Tell your doctor if your condition lasts or gets worse.

Nausea, vomiting, headache, dizziness, or pain/swelling at the injection site may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including:

• signs of kidney problems (such as change in the amount of urine)
• unusual tiredness
• hearing changes (such as ringing in the ears, decreased hearing)
• irregular heartbeat
• easy bleeding/bruising
• signs of liver disease (such as yellowing eyes/skin, dark urine, stomach/abdominal pain)

Tetracycline drugs such as tigecycline may rarely cause increased pressure around the brain (intracranial hypertension-IH). The risk of this side effect is greater for women of childbearing age who are overweight or who have had IH in the past. If IH develops, it usually goes away after tigecycline is stopped; however, there is a chance of permanent vision loss or blindness. Get medical help right away if you have:

• headaches that are severe or don't go away
• nausea/vomiting that doesn't stop
• vision changes (such as blurred/double vision, decreased vision, sudden blindness)

This medication may rarely cause a severe intestinal condition due to a bacteria called C. difficile. This condition may occur during treatment or weeks to months after treatment has stopped. Tell your doctor right away if you develop:

• diarrhea that doesn't stop
• abdominal or stomach pain/cramping
• blood/mucus in your stool

If you have these symptoms, do not use anti-diarrhea or opioid products because they may make symptoms worse.

Use of this medication for prolonged or repeated periods may result in oral thrush or a new yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:

• rash
• itching/swelling (especially of the face/tongue/throat)
• severe dizziness
• trouble breathing
