It is not recommended to take metronidazole tablets for a prolonged period. Metronidazole is an anti-anaerobic agent primarily used to treat conditions such as intestinal and extraintestinal amoebiasis and trichomoniasis. However, long-term use of metronidazole may lead to a range of adverse reactions and side effects. It may cause gastrointestinal reactions, including nausea, vomiting, upper abdominal pain, loss of appetite, and diarrhea. It can also induce neurological symptoms such as headache and dizziness. Additionally, the immune system may be affected, leading to skin allergies and other reactions. Metronidazole has certain hepatotoxicity, and prolonged use may result in abnormal liver function. Metronidazole is a prescription medication and must be used under the guidance of a physician. The instruction leaflet should be carefully read before use to understand proper administration, adverse reactions, contraindications, and other information. Metronidazole is contraindicated in pregnant women, breastfeeding women, and individuals with active central nervous system disorders or blood diseases.
