What is the dosage and proper administration time of castor oil in the treatment of constipation?

Castor oil is an over-the-counter stimulant laxative for the relief of occasional constipation. Side effects of Castor oil are abdominal pain, cramping, nausea, and felling faint. Adults and children over the age of 12 can take 1 to a maximum of 4 tablespoons (15ml to 60ml) in a single daily dose. Do not use for a period longer than 1 week. Take this product 2 or more hours before or after other medications. Laxatives may affect how other drugs work. When your doctor prescribes a new medication, be sure to discuss all your prescription and over-the-counter drugs, including dietary supplements, vitamins, botanicals, minerals, and herbals, as well as the foods you eat. Always keep a current list of the drugs and supplements you take and review it with your health care providers and your pharmacist. If possible, use one pharmacy for all your prescription medications and over-the-counter products. This allows your pharmacist to keep a complete record of all your prescription drugs and to advise you about drug interactions and side effects. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action.
