Loose motions continuing even after taking Metronidazole may happen because the cause is not always a bacterial or parasitic infection. Diarrhoea can also occur due to viral infection, food poisoning, contaminated water, stomach irritation, food intolerance, or side effects from medicines. In some cases, the body may simply need more time and proper hydration to recover. The most important thing right now is preventing dehydration. Drink enough water, ORS, coconut water, or light fluids in small amounts throughout the day. Eat simple foods like rice, curd, banana, toast, khichdi, or soup, and avoid oily, spicy, outside, or very sugary foods for a few days. Do not stop or continue antibiotics for longer than advised without proper medical guidance because unnecessary antibiotic use can sometimes worsen stomach problems. Please consult a doctor if you develop fever, blood in stool, severe stomach pain, vomiting, weakness, dizziness, or if loose motions continue for several more days despite treatment.

Swelling and infection in the vaginal area can be caused by bacteria, fungi, irritation, poor hygiene, sexually transmitted infections, or changes in vaginal pH. Metronidazole is often prescribed for certain vaginal infections, especially those caused by bacteria. Many people start to feel better, with less discharge, swelling, odour, or discomfort, after beginning treatment. This medicine is usually safe when taken as your doctor recommends, but some people may have side effects like nausea, stomach upset, a metallic taste, or dizziness. Do not drink alcohol while taking this medicine, as it can cause unpleasant reactions. To help with healing, keep the area clean and dry, avoid scented products, and wear loose cotton underwear to reduce irritation. Having sex may sometimes make discomfort worse until the infection clears up. If your swelling gets worse, itching increases, you develop a fever, notice thick white discharge, feel pain when urinating, or your symptoms do not improve after finishing treatment, please see your doctor again. You may need a different treatment if the infection has not cleared.
