Orfiril long is a medicine used to treat epilepsy and mania.
For epilepsy, the usual adult starting dose is 600 mg per day. For mania, the recommended starting dose is 750 mg, and the usual daily dose generally ranges from 1000 mg to 2000 mg.
Take Orfiril long by mouth with a small amount of liquid (e.g., water) before, during, or after a meal. The granules can also be mixed with soft food or drink. Do not chew the medicine.
The recommended maximum daily dose is generally 2000 mg for mania.
Suitable for older adults, with specific precautions. Low serum albumin levels increase the response. Consider potential adverse effects, such as hyponatraemia och hematological changes. Monitor liver function. (updated 10.11.2025)
