The prescribed dosage of hydrocodone varies depending on the patient and the cause of pain, according to Mayo Clinic. Some of the factors that influence dosage include the patient's age and the severity of the patient's pain.
Hydrocodone is available as a capsule or a liquid, explains Mayo Clinic. The amount of hydrocodone in the capsules varies between 5 and 10 milligrams. When prescribed as a capsule, the usual dosage is no more than eight capsules per day. When prescribed as a liquid, the dosage is usually no more than 67.5 milliliters per day. These dosages are usually lower for children and the elderly.
