Tinidazole (TDZ)

Tinidazole is an anti-parasitic drug used against protozoan infections. It is widely known throughout Europe and the developing world as a treatment for a variety of amoebic and parasitic infections. It is chemically similar to metronidazole—a drug with some unpleasant side effects that is used in the United States as first-line therapy for amoebae. Tinidazole has similar side effects but has a shorter treatment course. A large body of clinical data exists to support use of tinidazole for infections from amoebae, giardia and trichomonas, just like metronidazole. Tinidazole may be a therapeutic alternative in the setting of metronidazole tolerance. Tinidazole may also be used to treat a variety of other bacterial infections. The most common side effects reported with tinidazole are upset stomach, bitter taste and itchiness. Other side effects which occur are headache, physical fatigue, and dizziness.
