Serious side effects have been reported with Tygacil including the following:
- increased risk of death. In clinical trials, patients who received Tygacil were at a higher risk of death than patients receiving a comparable medication.
- hypersensitivity (severe allergic reaction). Tell your healthcare provider about any signs or symptoms of hypersensitivity, which include the following:
- chest pain
- swelling of the face, eyes, lips, tongue, arms, or legs
- difficulty breathing
- pancreatitis. Tell your healthcare provider about any signs or symptoms of pancreatitis (irritation of the pancreas):
- stomach pain
- back pain
- nausea or vomiting that gets worse after eating
- racing heart
- yellowing of the skin or eyes
- liver problems. Your healthcare provider will be measuring your blood for imbalances in the liver while on this medication. Report any stomach pain, yellowing of the skin or eyes, or changes in stool color, which may be a sign of liver problems.
- lower cure rate in certain pneumonias (lung infections). Patients with certain types of pneumonia (lung infections) that happened after using a ventilator are at a higher risk of not being cured when taking Tygacil.
- photosensitivity. Report any eye sensitivity to sunlight or bright lights or if you get a rash after being in the sun, which can be a sign of photosensitivity (more sensitivity to light).
- diarrhea. Diarrhea is a common problem caused by antibiotics, and it usually ends when the antibacterial is stopped. Even after starting treatment with antibiotics, some patients can develop watery and bloody stools (with or without stomach cramps and fever) as late as 2 or more months after having taken their last dose of the antibacterial. If diarrhea is severe or lasts more than 2 or 3 days, contact your doctor, as this may be a sign of an infection of the bowels.
- Clostridium difficile (C. difficile) associated diarrhea. Some antibiotics can kill the “good” bacteria in the colon leading to a growth of C. difficile bacteria. This “bad” bacterium can cause diarrhea and other digestive problems, and these problems may even occur 2 months after the last dose. Extra caution for this side effect is advised in the elderly population. Tell your healthcare provider if you experience any or all of the following symptoms:
- watery diarrhea (at least three bowel movements per day for two or more days)
- loss of appetite
- abdominal pain or tenderness
Tygacil can cause dizziness. Do not drive or operate heavy machinery until you know how this medication affects you.

- are allergic to tetracycline antibiotics such as tetracycline (Tetracin, Acnecycline), doxycycline (Doryx, Oracea, Vibramycin), minocycline (Solodyn, Minocin)

Tygacil and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Tygacil falls into category D. It has been shown that use of Tygacil in pregnant women caused some babies to be born with bone and tooth problems. However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby.
Tygacil and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if Tygacil crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Tygacil.
