This situation requires caution because Zandu Parad tablets may contain mercury-based Ayurvedic preparations, and accidental ingestion or exposure should not be ignored. Even if you feel fine now, the effect depends on how much was actually consumed, the type of tablet, and your body's response. In many cases, a single small exposure may not cause immediate, serious symptoms. However, it is still important to seek medical advice, as some effects may appear later and require monitoring. You should contact a doctor or poison information centre as soon as possible for proper assessment and guidance, especially if there is any doubt about ingestion. Avoid self-treatment and do not ignore it, even if you currently have no symptoms.
