PLIVA 334 is what? says that a pill marked “PLIVA 334” contains 500 milligrammes of metronidazole, which is also known as Flagyl. MedlinePlus says that it is a prescription drug used to treat infections in the reproductive system, GI tract, skin, vagina, and other parts of the body.

Metronidazole should be taken exactly as your doctor tells you to, says Even if the symptoms get better, the infection might not be gone for good. If you skip doses or stop taking this medicine before it’s done, you could get an infection that antibiotics can’t treat.

If you drink alcohol while taking metronidazole, you might get side effects like a fast heartbeat, redness or warmth under the skin, a tingling feeling, nausea, and vomiting. Metronidazole can also cause stomach pain, diarrhoea, dizziness, loss of balance, itchiness or discharge from the vaginal area, dry mouth, cough, runny nose, and a sore or swollen tongue.

Metronidazole can cause more serious side effects, such as tingling or numbness in the hands or feet, white patches or sores on the mouth or lips, pain or burning when urinating, watery or bloody diarrhoea, vision problems, trouble concentrating, changes in behaviour, fever, chills, muscle pain, stiff neck, and a severe skin reaction. If any of these serious side effects happen, you should see a doctor right away.
