Table of contents:

Trivastal (generically known as piribedil) is a medication used to treat symptoms of Parkinson's disease and other movement disorders. It is also sometimes used for the treatment of restless leg syndrome. It works by stimulating dopamine receptors in the brain, which can improve movement and reduce tremors.

Trivastal is often used in combination with levodopa, another medication commonly used to treat Parkinson's disease. Piribedil is available in sustained release coated tablets and is contraindicated in case of fructose intolerance, glucose, and sucrose.

Use and Dosage

Trivastal comes in the form of a sustained-release tablet that is taken orally, usually taken once a day, with food, and at the same time each day to maintain a consistent level of medicine in the bloodstream. Swallow the tablet whole and do not chew, crush, or break the tablet. You should take the medication in the dose and duration as advised by your doctor. If you have difficulty swallowing pills, you should speak with your doctor or pharmacist about possible alternative formulations or options.

The initial dose may vary, depending on the individual's medical condition, but the usual starting dose of Trivastal Retard 50, a sustained release coated tablet, is one tablet (50mg) daily during the first week, after which the dosage should be gradually increased. However, take Trivastal Sustained Release Tablet only under the guidance of a physician. Trivastal Tablet SR should be taken with food to avoid stomach upset. Take Trivastal LA Tablet SR at the same time each day to maintain a consistent level of medicine in the bloodstream.

Take the missed dose as soon as you remember. If it is almost time for the next scheduled dose, then the missed dose can be skipped. Contact your doctor if you have missed more than one scheduled dose of the medication.
