Always take psyllium with a full glass of water to prevent choking or esophageal blockage. If you experience persistent discomfort, reduce the dose temporarily.

Psyllium fiber can interfere with the absorption of certain medications if taken at the same time. It is generally recommended to take psyllium at least 2 hours before or after prescription medications. Consult your pharmacist or healthcare provider for guidance specific to your medications.

Psyllium husk is a natural fiber source that is not systemically absorbed, so it is generally considered safe during pregnancy and breastfeeding. However, always consult your healthcare provider before starting any new supplement during pregnancy or nursing.

This product is formulated for adults. Children have different fiber requirements based on age and weight. Consult a pediatrician before giving any fiber supplement to a child, and supervise to ensure adequate water intake.

Psyllium husk powder should not be taken by individuals with bowel obstructions, difficulty swallowing, or esophageal narrowing. The powder expands significantly when mixed with liquid and could cause a blockage. Seek medical advice if you have any gastrointestinal conditions before using this product.
