Miralax (polyethylene glycol 3350) is typically taken once a day for up to 7 days to relieve constipation. The usual adult dose is 17 grams mixed in 8 ounces of liquid. It generally produces a bowel movement within 1 to 3 days. If constipation persists or the product is needed for longer than 7 days, one should consult a healthcare provider. In some cases, under medical supervision, longer use (up to two months in children and six months in adults) may be safe for chronic constipation, but this should be guided by a doctor to ensure no underlying health issues are missed. Taking Miralax more frequently or for longer than recommended without consulting a healthcare provider may cause side effects or mask more serious conditions. Common side effects include gastrointestinal symptoms such as cramping, bloating, nausea, and diarrhea, while long-term use without supervision may lead to electrolyte imbalances or other complications. In summary, Miralax can be taken once daily for up to 7 days safely without medical advice, but longer use requires healthcare provider guidance.
