Tygacil – Tigecycline uses, dose and side effects


50 mg powder for infusion, solution

What Tygacil is and what it is used for

Tygacil is an antibiotic in the group of glycylcyclines that works by stopping the growth of bacteria that cause infection.

Your doctor has prescribed Tygacil because you or your child over 8 years of age has one of the following serious infections.

  • Complicated infections in the skin and soft tissues ( tissues under the skin), excluding foot infections in patients with diabetes.
  • Complicated infection in the abdominal cavity

Tygacil is only used when your doctor considers other antibiotics unsuitable.

What you need to know before you receive Tygacil

Do not use Tygacil

  • If you are allergic to tigecycline or any of the other ingredients of this medicine (listed in section 6). If you are allergic to tetracycline antibiotics (eg, minocycline, doxycycline, etc.), you may be allergic to tigecycline.

Warnings and precautions

Talk to your doctor or nurse before receiving Tygacil:

  • If the wound does not heal normally.
  • If you suffer from diarrhea before receiving Tygacil. If you get diarrhea during or after your treatment, tell your doctor right away. Do not take any diarrhea medicine without first checking with your doctor.
  • If you have had any side effects in the past due to antibiotics belonging to the tetracycline class (eg skin sensitization to sunlight, discoloration of developing teeth, inflammation of the pancreas, and changes in certain laboratory values ​​intended to measure how well your blood clots).
  • If you have or have previously had, liver problems. Depending on the condition of your liver, your doctor may reduce the dose to avoid possible side effects.
  • If you have a blockage of the bile ducts (cholestasis).
  • If you suffer from any type of bleeding disorder or are treated with anticoagulants, as this medicine may affect blood clotting.

During treatment with Tygacil:

  • Tell your doctor immediately if you experience symptoms of an allergic reaction.
  • Tell your doctor immediately if you experience severe stomach pain, nausea, and vomiting. These symptoms may be signs of inflammation of the pancreas ( acute pancreatitis ).
  • For some severe infections, your doctor may consider using Tygacil together with other antibiotics.
  • Your doctor will monitor you closely to make sure no other bacterial infection develops. If you suffer from another bacterial infection, the doctor may prescribe another antibiotic that is specific to that infection.
  • Although antibiotics including Tygacil work against some bacteria, other bacteria and fungi may continue to grow. This is called overgrowth. Your doctor will monitor you for possible infection and treat you if necessary. If you receive Tygacil, your doctor will monitor you closely to make sure no other infection develops, and treat you if necessary.


Tygacil should not be used in children under 8 years of age because there is a lack of data on safety and efficacy in this age group and because it can cause permanent defects in the teeth, such as discoloration of developing teeth.

Other medicines and Tygacil

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
