Off-label uses

• Chorea
• Photosensitivity-related seizures
• Sedative-hypnotic withdrawal

Contraindications

• Hypersensitivity to drug or tartrazine (some products)
• Hepatic impairment
• Urea cycle disorders

Precautions

Use cautiously in:

Administration

• Give I.V. only when oral therapy isn't feasible.
• For I.V. use, dilute valproate sodium in at least 50 ml of dextrose 5% in water, lactated Ringer's solution, or normal saline solution. Infuse over 1 hour at a rate slower than 20 mg/minute.
• Know that I.V. and P.O. dosages and dosing frequencies are identical. However, patient should be switched to oral therapy as soon as possible.
• Give oral forms with food.
• Be aware that divalproex extended-release and delayed-release forms are not bioequivalent.
• Make sure patient swallows divalproex extended-release tablets and valproic acid capsules whole without chewing or crushing.
• If patient can't swallow capsule containing coated particles, sprinkle entire contents of capsule onto about 5 ml of semisolid food, such as pudding or applesauce, immediately before giving.
• Don't give syrup in carbonated beverages (may cause mouth and throat irritation).

Skin: rash, alopecia, bruising

Other: abnormal taste, increased appetite, weight gain, flulike symptoms, infection, infusion site pain and reaction, multiorgan hypersensitivity reaction

Interactions

Drug-drug.Activated charcoal, cholestyramine: decreased valproate absorption

Antiplatelet agents (including abciximab, aspirin and other nonsteroidal anti-inflammatory drugs, eptifibatide, tirofiban), cefamandole, cefoperazone, cefotetan, heparin, thrombolytics, warfarin: increased risk of bleeding

Barbiturates, primidone: decreased metabolism and greater risk of toxicity of these drugs, decreased valproate efficacy

Carbamazepine: increased carbamazepine blood level, decreased valproate blood level, poor seizure control

Chlorpromazine: decreased valproate clearance and increased trough level

Cimetidine: decreased valproate clearance

Clonazepam: absence seizures in patients with history of these seizures

CNS depressants (such as antihistamines and antidepressants, MAO inhibitors, opioid analgesics, sedative- hypnotics): additive CNS depression

Diazepam: displacement of diazepam from binding site, inhibited diazepam metabolism

Erythromycin, felbamate: increased valproate blood level, greater risk of toxicity

Ethosuximide: inhibited ethosuximide metabolism

Lamotrigine: decreased valproate blood level, increased lamotrigine blood level

Phenytoin: increased phenytoin effects and risk of toxicity, decreased valproate effects

Salicylates (large doses in children): increased valproate effects

Topiramate: increased risk of hyperammonemia with and without encephalopathy and hypothermia

Tricyclic antidepressants: increased blood levels of these drugs, greater risk of adverse reactions

Zidovudine: decreased zidovudine clearance in patients with human immunodeficiency virus

Drug-diagnostic tests.Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, bilirubin: increased levels

Bleeding time: prolonged

Ketone bodies: false-positive results

Platelets, white blood cells: decreased counts

Thyroid function tests: interference with results

Drug-behaviors.Alcohol use: additive CNS depression

Patient monitoring

Closely monitor neurologic status. Watch for seizures and suicidal behavior or ideation.

If hyperammonemia or hyperammonemic encephalopathy (unexplained lethargy and vomiting or changes in mental status) is suspected, measure ammonia level.

Evaluate GI status. Stay alert for signs and symptoms of pancreatitis. Consider discontinuing drug if pancreatitis is diagnosed.

Watch for diverse signs and symptoms of multiorgan hypersensitivity reaction, such as fever and rash associated with other organ system involvement (lymphadenopathy, hepatitis, liver function test abnormalities, hematologic abnormalities, pruritus, nephritis, oliguria, hepatorenal syndrome, arthralgia, and asthenia). Discontinue drug if multiorgan hypersensitivity reaction occurs.
• Monitor I.V. infusion site for local reactions.
• Assess CBC (including platelet count), prothrombin time, International Normalized Ratio, and liver function tests.
• Monitor valproate blood level; therapeutic range is 50 to 100 mcg/ml.

Patient teaching

• Instruct patient to take with food to minimize GI upset.
• Tell patient taking extended-release tablets or valproic acid capsules to swallow them whole without chewing or breaking.
• Inform patient taking capsules with delayed-release pellets that he may swallow them whole or open them and sprinkle contents onto a teaspoon of semisolid food, such as pudding or applesauce.
• Tell patient (or parents) that valproate syrup shouldn't be taken with carbonated beverages.

Advise patient to immediately report signs and symptoms of liver dysfunction (such as malaise, weakness, lethargy, appetite loss, vomiting, or yellowing of skin or eyes), signs and symptoms of pancreatitis (such as abdominal pain, nausea, vomiting, loss of appetite), or suicidal behavior or ideation.

Tell patient to immediately report unexplained signs and symptoms that may reflect hypersensitivity reaction (fever, rash, hepatitis signs and symptoms, bleeding or bruising, itching, urinary problems, muscle pains, or weakness).
• If patient is taking drug for seizure control, tell him to avoid driving and other hazardous activities.

Caution patient not to stop therapy abruptly.
• Instruct patient to avoid alcohol.
• Stress importance of follow-up laboratory tests.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and behaviors mentioned above.

Patient discussion about Depakote

Q. My brother has had serious side effect with depakote like stomach cramps.. My brother has had serious side effect with depakote like stomach cramps, hair loss, nausea and indigestion when he had jaundice and later the doctor changed the med to lamotrigine ….will this have any side effect….?

A. All medications have possible side effects, unfortunatley it is a trial and error issue until your brothers doctor finds a medication that is right for him... My partner has had some sensitivities to medications and was switched to Lamotrigine and has not experienced any side effects. Your pharmasist should give you a print out aobut the medications and its possible side effects, read that print out to know for sure and be aware. If he experiences any serious side effects dont hesitate to get him back to the doctors right away.

Q. Will my bipolar meds (lamictal and depakote) interfere with my birth control pills? We have been married for the past 12 yrs but we don’t have a child because I am paranoid of delivery. But it doesn’t affect our intimacy. I am using birth control pills for the past few years and I could rely on it. Now the new problem is that I was recently diagnosed as bipolar-II. The Doctor prescribed some medicines for me. Will my bipolar meds (Lamictal and Depakote) interfere with my birth control pills?

A. there are interactions, birth control pills can reduce the amount of Lamictal in the blood, causing it to be less affective. the drug level in plasma should be monitored. ask both your therapists about it- your gynecologist and the psychiatrist.
