How long until laduda begins working as lamictal takes forever...also what is its interaction w / tegretol?
Speak w/ your Dr.: I am not sure what dose of Latuda (lurasidone) you are taking, but it may have to be raised if you are not experiencing a response after an adequate duration of a month or longer. Tegretol speeds up the metabolism of Lamictal and lowers its levels. You may experience more dizziness, blurry or double vision and unsteady gait with the combination. ...Read more
Tegretol XR: Start 100-200mg in two divided doses followed by a slow increase in dosage (every3-7days) until the effect is obtained, often 800-1200mg daily. However, this should only ever be under the supervision of a doctor. ...Read more
Tegretol XR: Is still the drug of choice for the initial management of paroxysmal neuralgias despite the presence of potentially serious side effects. The specific mechanism of carbamazepine is presumed to be stabilization of neuronal membranes by blocking sodium channels. Hope it helps. ...Read more
3-12 hours: Blood levels peak 3-12 hours after ingesting tablets but it may take 3 - 5 weeks to reach a consistent level since the drug induces its own metabolism (autoinduction). The dosage may have to be slowly increased to reach the appropriate blood level. I notice you describe pain - if taking tegretol for that reason it may take 4-6 weeks before you notice an improvement. ...Read more
Went from 600mg of tegretol to 400 mg of tegretol for 1 week-going back up to 600mg. How long until therapeutic level is reached? (on 600 for 5 years)
Well...: After a week levels should be back to where they should at 600 mg. ...Read more
I have been on 600 mg of tegretol for 5 years-my bloodwork is always ok. At what point should I consider stopping it because of long term problems?
Tegretol: The need to continue tegretol depends very much on the reason it's being prescribed. You haven't volunteered this in your question or additional information. In some cases it could be very dangerous to stop tegretol, as you could have seizures, etc. Please discuss your question with the doctor who's been following you, as s/he will be familiar with your history and medical needs. ...Read more
I have trilgimal nerugia I'm on gabapintin dilanta just started tegretol 100 chewable. My blood levels on dilanta was 4.5 is it still working?
Combination: The combined use of tegretol and Dilantin is tricky and should be guided by a neurologist who is most used to using two antiseizure medications simultaneously. The usual therapeutic level of Dilantin is 10to20 but it can lower the serum level of tegretol and perhaps you're recommended to take a lower dose because of this effect on tegretol. ...Read more

Monitoring: Carbamazepine requires not just monitoring of bipolar symptoms to optimize dose, but also blood level to do so. In addition, blood tests need to be performed regularly to assess blood counts, and liver function. It is true that over the long term the risks of these problems diminish, but nevertheless, continue to require assessment. ...Read more
Hi! I have sleep seizures and have to take adcal-d3, due to long term use of tegretol. I am off tegretol now. Adcal tastes terrible! Any alternative?
Vitamin d: Now that you're off tegretol, there isn't a presumable reason to keep taking calcium with vitamin d unless you have checked your levels of vitamin d and proven deficient. Calcium supplementation is no longer generally recommended. Vitamin d supplementation cannot hurt, especially if you don't get enough sunshine where you live. ...Read more

If carbamazepine isn't working to treat my trigeminal neuralgia, what is a good drug to try next?
Trileptal: Is reported to be effective for trigeminal neuralgia. Some clinicians now prefer to use oxcarbazepine (Trileptal) as their first line drug for trigeminal neuralgia because of its reduced side effect profile. Unfortunately, about half of TN sufferers eventually become dissatisfied with medical therapy, explore surgical options. ...Read more
How long would it take for a steady state concentration from 100mg of lamictal to 50 mg--keeping in mind I also take 600 mg of tegretol.
Probably 2-3 days: Since the half-life of Lamictal is ordinarily about 33 hours (presuming normal kidney function) and the elimination half-life is decreased significantly by the presence of tegretol that speeds lamictal's metabolism, I think it should only take 2 to 3 days to reach steady state on 50 mg daily after having previously been on 100 mg daily. ...Read more
Since being on cymbalta (duloxetine) 60 mg. 2 months very hyper...Also take tegretol -klonopin-lamictal...If I go back to 30 how long til steady state. Is this rare?
Cymbalta (duloxetine) hypo mania: This is not rare at all. We are learning to rely less on antidepressants in bipolar disorder because of this. Antidepressants, especially snri's like Cymbalta and Effexor may cause more mood switching than most. Wellbutrin is said to cause it the least. The issue is not the steady state, but whether this effect will continue even at 30 mg a day. Latuda (lurasidone) is approved for treatment of BP depression. ...Read more
I have been taking carbamazepine chewable pills for 5 years for my seizures but I haven't had a seizure for a long time now and I just started smoking weed this year does this affect my lab results?
No: It will not affect your carbamamazepine level. ...Read more
Does nocturnal temporal lobe epilepsy disappear? I have no seizures since 7 years. The seizures were 40 seconds long. I've always taken carbamazepine.
Can: Most large studies of withdrawing seizure medicines were done at the 2 yr seizure-free mark. Evaluation by a neurologist can help evaluate the risk of tapering off. Eeg and MRI along with the history and exam help determine chances of success. If it's the genetic nocturnal tle, then recurrence would be likely off aeds. ...Read more
Both fairly safe,: Yet, I would tend not to use tegretol due to its potential for adverse effects, such as lowering sodium, causing bone marrow anemias, affecting liver function, but also raising cholesterol levels (which indirectly might harm the heart eventually). Big issue with Lamictal is occasional rash, but otherwise, not a bad choice and well tolerated. ...Read more
Have taken klonopin 1.5, tegretol 600, lamictal 100, Cymbalta (duloxetine) 60 bipolar-ocd for 8 years-liver functions fine-how long before I have liver problems?
Most likely never: While each of these medications have some potential to affect liver function tests - it being greatest in Tegretol - most of the changes tend to be benign (or harmless). I would worry to much, particularly if you doctors continue to monitor this periodically. Best of luck. ...Read more
Are the meds Chlorpromazine, Haloperidol, metoclopramide, phenytoin, valproic acid, &carbamazepine safe to eat to treat frequent hiccups. How long to take?
An old drug: Tegretol has been on the market for many years. It was one of the first antiseizure medications and is still prescribed pretty frequently. It is not without a slight risk for problems, however. Your doctor checks blood counts looking for signs of anemia or bone marrow problems, liver function tests to make sure the liver isn't affected, and a tegretol level to see how much is in your system. ...Read more
Information below: The absorption of carbamazepine in man is relatively slow. When taken in a single oral dose, the carbamazepine tablets and chewable tablets yield peak plasma concentrations of unchanged carbamazepine within 4 to 24 hours. With respect to the quantity of carbamazepine absorbed, there is no clinically relevant difference between the various dosage forms. However, carbamazepine suspension is absorbed somewhat faster than the tablet; peak plasma levels are reached within 2 hours. Following b.i.d. dosage regimens, higher peak levels and lower trough levels are obtained with the suspension than with the tablets. Steady-state plasma levels are comparable for carbamazepine suspension given t.i.d. and carbamazepine tablets given b.i.d., when administered at the same total daily dose. ...Read more
When toxic: Tegretol is difficult to use. Sudden high levels can occur when treated with certain antibiotics. Toxicity can occur from biproducts even if level is okay. Better medications are now available. Most adults can tolerate up to 800 mg per day. ...Read more
Not my first choice: Tegretol does control the pain of trigeminal neuralgia, but so do other meds, and I would try Lyrica (pregabalin) first, as it has few if any drug-drug interactions, and is, in my experience extremely effective. Tegretol is an older drug with many potential side effects, including liver and bone marrow issues, low sodium, gastrointestinal problems, and elevation of cholesterol. Do not understand why choice. ...Read more
