Drug Uses Lioresal is used to treat muscle spasms caused by multiple sclerosis or other diseases. It might also be used by your doctor in other cases as he deems fit. Usage Following the dosage instructions of your doctor is the best way to use any medication. If you are unsure or do not remember the instructions then you may read the medicine label for more detailed information. Swallow the medicine whole and do not crush or chew the tablets. It is very important that you complete the dosage schedule and do not interrupt it in between without seeking prior consultation from your doctor. Drug Class and Mechanism Lioresal is classified as a muscle relaxant. It helps by reducing the frequency and severity of muscle spasms that occur as a result of neurological disorders such as multiple sclerosis. Missed Dose Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule. Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects. Storage Store Lioresal between 59 and 77 degrees F (15 and 25 degrees C). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets.
