Can I use this product regularly, and when should I stop and see a doctor instead?

No — this is not a product for regular, ongoing use. Castor oil works by stimulating peristalsis, and stimulant-type products in general are meant to bridge a short episode, not to become part of a daily routine. Typical situations where people reach for it are after travel, during a change in eating pattern, or in a period when bowel activity feels slower than usual. Once things return to normal, the capsules go back in the cupboard.

Treat the following as clear signals to talk to a doctor or pharmacist instead of continuing:

• Constipation that keeps returning or becomes frequent — a stimulant is not a solution for a recurring pattern, and the underlying cause deserves proper attention.
• Severe constipation, or constipation accompanied by pain, bloating, nausea, or unexplained changes in bowel habits.
• Uncertainty about whether a laxative-type effect fits your situation at all — for example with a sensitive digestive system or when taking medicines or other supplements.

Alongside occasional use, it usually makes more sense to look at everyday factors — fluid intake, fiber in the diet, and regular movement — since a supplement is not a substitute for a balanced diet. The product is not appropriate during pregnancy or breastfeeding.
