How to use divalproex oral
Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking divalproex sodium and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth once daily or as directed by your doctor. You may take it with food if stomach upset occurs. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
The dosage is based on your age, weight, medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day to keep the amount of medication in your blood constant.
If this medication is used for seizures, do not stop taking it without consulting your doctor. Your condition may become worse if the drug is suddenly stopped. Your dose may need to be gradually decreased.
Divalproex sodium does not relieve acute migraine headaches. Take other medications as directed by your doctor for acute attacks.
Inform your doctor if your condition does not improve.
Diarrhea, dizziness, drowsiness, hair loss, blurred/double vision, change in menstrual periods, ringing in the ears, shakiness (tremor), unsteadiness, weight changes may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
A small number of people who take anticonvulsants for any condition (such as seizure, bipolar disorder, pain) may experience depression, suicidal thoughts/attempts, or other mental/mood problems. Tell your doctor right away if you or your family/caregiver notice any unusual/sudden changes in your mood, thoughts, or behavior including signs of depression, suicidal thoughts/attempts, thoughts about harming yourself.
Severe (sometimes fatal) brain disorder (encephalopathy) has rarely occurred, particularly in patients with certain metabolic disorders (urea cycle disorders). Tell your doctor right away if you develop unexplained weakness, vomiting, or sudden mental/mood changes (such as confusion).
Get medical help right away if you have any very serious side effects, including: chest pain, easy bruising/unexplained bleeding, fast/slow/irregular heartbeat, swelling of hands/feet, uncontrolled eye movement (nystagmus), feeling cold/shivering, rapid breathing, loss of consciousness.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: fever, swollen lymph nodes, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
