In patients with epilepsy, there have been reports of breakthrough seizures occurring with the combination of valproate and phenytoin. The dosage of phenytoin should be adjusted as required by the clinical situation. The clinical relevance of this displacement is unknown. Warfarin - In an in vitro study, valproate increased the unbound fraction of warfarin by up to The therapeutic relevance of this is unknown; however, coagulation tests should be monitored if DEPAKOTE therapy is instituted in patients taking anticoagulants.
Acetaminophen - Valproate had no effect on any of the pharmacokinetic parameters of acetaminophen when it was concurrently administered to three epileptic patients. A variety of neoplasms were observed in both species. The chief findings were a statistically significant increase in the incidence of subcutaneous fibrosarcomas in high dose male rats receiving valproic acid and a statistically significant dose-related trend for benign pulmonary adenomas in male mice receiving valproic acid.
The significance of these findings for humans is unknown. Mutagenesis Valproate was not mutagenic in an in vitro bacterial assay Ames test , did not produce dominant lethal effects in mice, and did not increase chromosome aberration frequency in an in vivo cytogenetic study in rats.
Increased frequencies of sister chromatid exchange SCE have been reported in a study of epileptic children taking valproate, but this association was not observed in another study conducted in adults. There is some evidence that increased SCE frequencies may be associated with epilepsy. The biological significance of an increase in SCE frequency is not known. Pregnancy Pregnancy Category D: Nursing Mothers Valproate is excreted in breast milk.
It is not known what effect this would have on a nursing infant. Consideration should be given to discontinuing nursing when divalproex sodium is administered to a nursing woman. 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. See also Warning section. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. I haven't experienced the weight loss side effect, but did lose a lot of hair at first.
The hair seems to be thickening up now. I would give it 10 stars except for the hair loss. This drug divaproex sodium makes me lose weight to the point it's actually a bit alarming.
I've stopped and started times as I never take anything more than a year without stopping. Every time I take it like this week for example I started at pounds 5"7 female. I don't work out or exercise ever and have dropped 12 pounds in 3 days.
It actually usually gets so bad I have to go talk to my doctor about my weight loss. I can stomach food but it comes out in liquid form within 15 mins and clears my system.
This drug is a major weight loss drug from me. I know everytime I start it it's a given I will be losing 10 pounds minimum. The first attempt lasted a week; as it can exaggerate the effects of other meds, I became so drowsy I couldn't drive. For the second attempt, it wasn't combined with any other medication and lasted 3 weeks. I felt continually agitated and anxious, began to quickly gain weight, had terrible gas and was going to the bathroom times a day.
Additionally, my hair began to fall out so quickly, even my husband noticed and he's NOT very observant! Interpretation of valproic acid concentrations in children should include consideration of factors that affect hepatic metabolism and protein binding.
Pediatric Clinical Trials Divalproex sodium delayed-release tablets were studied in seven pediatric clinical trials. Two of the pediatric studies were double-blinded placebo-controlled trials to evaluate the efficacy of Divalproex sodium extended-release tablets for the indications of mania patients aged 10 to 17 years, 76 of whom were on Divalproex sodium extended-release tablets and migraine patients aged 12 to 17 years, of whom were on Divalproex sodium extended-release tablets.
Efficacy was not established for either the treatment of migraine or the treatment of mania. The remaining five trials were long term safety studies. Two six-month pediatric studies were conducted to evaluate the long-term safety of Divalproex sodium extended-release tablets for the indication of mania patients aged 10 to 17 years. Two twelve-month pediatric studies were conducted to evaluate the long-term safety of Divalproex sodium extended-release tablets for the indication of migraine patients aged 12 to 17 years.
One twelve-month study was conducted to evaluate the safety of Divalproex Sodium Sprinkle Capsules in the indication of partial seizures patients aged 3 to 10 years. Juvenile Animal Toxicology In studies of valproate in immature animals, toxic effects not observed in adult animals includedretinal dysplasia in rats treated during the neonatal period from postnatal day 4 and nephrotoxicity in rats treated during the neonatal and juvenile from postnatal day 14 periods.
A higher percentage of patients above 65 years of age reported accidental injury, infection, pain, somnolence, and tremor. Discontinuation of valproate was occasionally associated with the latter two events. It is not clear whether these events indicate additional risk or whether they result from preexisting medical illness and concomitant medication use among these patients. A study of elderly patients with dementia revealed drug related somnolence and discontinuation for somnolence [see Warnings and Precautions 5.
The starting dose should be reduced in these patients, and dosage reductions or discontinuation should be considered in patients with excessive somnolence [see Dosage and Administration 2. There is insufficient information available to discern the safety and effectiveness of valproate for the prophylaxis of migraines in patients over The capacity of elderly patients age range: In overdose situations, the fraction of drug not bound to protein is high and hemodialysis or tandem hemodialysis plus hemoperfusion may result in significant removal of drug.
The benefit of gastric lavage or emesis will vary with the time since ingestion. General supportive measures should be applied with particular attention to the maintenance of adequate urinary output. Naloxone has been reported to reverse the CNS depressant effects of valproate overdosage.
Because naloxone could theoretically also reverse the antiepileptic effects of valproate, it should be used with caution in patients with epilepsy. Divalproex Description Divalproex sodium USP is a stable co-ordination compound comprised of sodium valproate and valproic acid in a 1: Chemically it is designated as sodium hydrogen bis 2-propylpentanoate.
Divalproex sodium USP has the following structure: Divalproex sodium USP occurs as a white to off white powder with a characteristic odor, very soluble in chloroform, freely soluble in methanol and ethyl ether, soluble in acetone, practically insoluble in acetonitrile.
Divalproex sodium extended-release tablets USP, mg are for oral administration. Divalproex sodium extended-release tablets USP, contain Divalproex sodium USP in a once-a-day extended-release formulation equivalent to mg of valproic acid. Hydroxy ethyl cellulose, hypromellose, lactose monohydrate, microcrystalline cellulose, polyethylene glycol, silicon dioxide, and titanium dioxide. Divalproex - Clinical Pharmacology The mechanisms by which valproate exerts its therapeutic effects have not been established.
It has been suggested that its activity in epilepsy is related to increased brain concentrations of gamma-aminobutyric acid GABA. Now as an adult, I get sleepy so easily that I must nap every day. Because of this, at night, I usually can't sleep properly. Unfortunately, I do watch a lot of TV and sometimes am online.
Reading doesn't help more than half the time with helping me get sleepy. Only tea and exercise has helped me sleep properly. I'm worried that this will affect my work because I get really tired two hours after taking my medicine. Is there anything I can drink or take to help keep me awake and active? I ask this because I must avoid alcohol and too much caffeine and I must east properly at all times. My second question is what can I do to avoid my hot flashes? Sometimes when I take a shower and the water is very warm or the humidity is stuffing my oxygen intake, I get a three- to five-second hot flash.
So far, opening a window and maintaining the water cooler has helped them go away. But it has not stopped them from occurring. What can I do? The questions that you are asking should be discussed with your health care provider. Over-the-counter medications that may help keep you awake interact with the medications you are taking and should be avoided. You should also mention to your provider the hot flashes you are having.
All strange feelings you see or feeling should be reported to your provider, so he or she can give the best treatment possible for all your medical conditions. Gerald Levy, RPh Q: Can Depakote or Resperidine cause false protein in urine tests?
Depakote divalproex sodium may lead to a false urine ketone test. The reason is that the body gets rid of valproate's waste product which is similar in structure to ketones through the urine. Regarding the other medication you mentioned Resperidine , unfortunately, we're unable to answer your question because we could not find any drug by that name. I am taking Depakote ER mg. If I eat a big dinner, would drinking a glass of wine after dinner be bad? Alcohol is not recommended while taking Depakote ER since the alcohol may increase the chance of side effects occurring.
Having 1 glass of wine may be okay, but it would be best to ask your doctor before doing so. They know your medical history and can better determine the risks that this may pose.
May cause central nervous system CNS depression and impair physical or mental abilities. Concomitant administration of topiramate with valproate has also been associated with hypothermia in patients who have tolerated either sodium alone. The following list provides information about the potential for an influence of several commonly prescribed medications on valproate pharmacokinetics. The first attempt lasted a week; as it can exaggerate the effects of other meds, I became so drowsy I couldn't drive. Valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other treatments have failed to provide adequate symptom control or are otherwise unacceptable. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Occasionally very alprazolam extended-release 0.5mg and my stomach from time to time gets a little funny, just take with lots of mood and food. The absolute risks for autism spectrum disorderswere 4. This is not a complete list of side effects that can occur with Depakote. A decrease in valproate dosage may be necessary when felbamate therapy is initiated. Meropenem - Subtherapeutic valproic acid levels have been reported when meropenem was coadministered, divalproex sodium mood disorders. Drugs for which a potentially important valproate interaction has been observed: It is always important to divalproex aware of the disorder effects of a medication so you can recognize the symptoms if they occur. Fractures, decreased bone mineral density, osteopenia, osteoporosis, and weakness.
