Some of the common side effects of tinidazole include a metallic taste in the mouth, headache, decreased appetite, and gastrointestinal issues such as stomach cramps, vomiting or nausea, gas, diarrhea, and constipation.
This is not a complete list of adverse effects – though these are among the most common. Seek medical attention right away if you experience symptoms such as:
- Numbness or tingling of hands or feet
- Swelling of the face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs
- Difficulty swallowing or breathing
As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with and any medication/ supplements you are currently taking before starting treatment with tinidazole. Tinidazole can interact with other forms of medication and substances, causing potentially serious side effects.
In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication, and do not breastfeed while you are taking tinidazole and for 3 days after you finish your treatment.
