Zandu Nityam Tablet is generally safe for short-term use to relieve constipation when taken as per the recommended dosage. However, using it daily or for a long time without medical advice is not advisable, as regular use of laxatives can interfere with normal bowel movement and may mask underlying health issues. If constipation persists or you need it frequently, consult your doctor to find the root cause and get the most appropriate treatment plan.
