Are There Any Drug Interactions Between Lamictal And Zyprexa?

Consultation
Detailed Answer:
Thanks very much for your question.
Standard treatment of bipolar 1 disorder consists of at least one mood stabilizer and usually an atypical neuroleptic in addition. In your son's case, the mood stabilizer is Lamictal and the atypical neuroleptic is Zyprexa. This is a standard treatment regimen. Your son's dose of Zyprexa is exceedingly low at 2.5mg - typical treatment doses are in the range of 10-20mg daily.
Lamictal is the mood stabilizer with the fewest side effects. Depakote and Lithium are the others, and they have more side effects, so Lamictal is a good choice. Zyprexa 2.5mg daily is simply not enough to treat your son effectively in the long term. He needs a mood stabilizer and Lamictal is the best-tolerated of these.
There are no interactions between these two drugs to be aware of.
Of course you should be an advocate for your son, but your doctor is doing an excellent job with your son's medication management. Trust them.
My name is Dr. Sheppe, and I am an XXXXXXX psychiatrist working in New York City. For a personalized comprehensive evaluation, treatment recommendations, or individual therapy, ask me at HealthCareMagic at this private link: XXXX


You are right that I am having trouble trusting the medication regimes. This may be because XXXXXXX has struggled with compliance due to side effects of zyprexa, such as lethargy and weight gain. He has never used Lamictal, so I am glad to hear that this is the most tolerated mood stabilizer.
Does Lamictal result in weight gain as well as zyprexa? XXXXXXX has lost 60 pounds since being on the 2.5 mg of zyprexa, as opposed to the being on 5 mg, 7.5 mg,or 10 mg doses. Of course this is a positive for his health and his self-confidence. The psychiatrist said he could take another med to limit weight gain, the name of which I cannot remember. I do understand that the 2.5mg dose is low, but it has helped when XXXXXXX has been consistent, more accurately, religious in taking it.
It seems that XXXXXXX is overly sensitive to side-effects of medications, which then leads to non-compliance. It is a balancing act for sure. His consistent work schedule right now is therapeutic in itself, and learning to say no to too many outside demands at once is huge. I am concerned that increasing the zyprexa will lead to significant fatigue and an inability for XXXXXXX to keep working as he has been. He could become too lethargic to rise at 5:30 AM, and not alert enough to be able to drive that early in the morning. Does Lamictal typically have fatigue and lethargy as a side effect as well?
I did not mention that XXXXXXX is also taking a 2 capsule dose of Empower Plus, (see www.truehope.com for more info), a micronutrient supplement which has assisted many patients with controlling mood swings, as long as it is taken consistently and as directed. Consistency is a huge factor in whatever the treatment. I think the combination of the low dose of zyprexa and the Empower Plus, as well as the regular healthful daily work schedule, is holding Justin's mood right now. The physical work in commercial plumbing is a positive expenditure of his energy. XXXXXXX has found a balance between his daily physical work, and his filming and editing of music videos for a friend in the evenings, as an outlet for his creative side. He is tired by 9:00 PM, takes his meds and is asleep usually by 9:30 ish. On weekends he is needing extra rest to make up for the long 9 hour work days (11 hours including commute time there and back) during the week. I think he is doing amazing right now, but he has been at this job only one month. I know that bipolar is a condition that requires constant vigilance. It so often feels like XXXXXXX and his family are walking a tight-rope.
As family members we do stay connected and watch him closely, and encourage him to stay consistent with whatever treatment he is taking at the time.
How common is it that increasing a medication such as zyprexa interferes with an individual's ability to be alert for work and driving? XXXXXXX is up at 5:30 am and needs to be driving by 6:00 AM, for a full hour before arriving at the job site at 7:00 AM. He cannot take chances with being fatigued and lethargic. He also is operating some power tools at his work.
Thank you again for your insights!

Detailed Answer:
Thanks so much for the additional information and insights.
Lamictal is at much lower risk of causing the things you are worried about -- sedation and weight gain. It is a very good drug in this regard and should help your son.
Zyprexa is known for sedation, but only when you are first taking it, as the body habituates to this effect and the sedation disappears overtime. Zyprexa is also notorious for weight gain, which is an unfortunate long-term side effect. There are other effective atypical neuroleptics that can replace Zyprexa (or Abilify which he could not tolerate), such as Risperdal, Latuda, or Saphris, if your son is unable to tolerate Zyprexa at therapeutic doses (higher than his current small dose of 2.5mg).
I should also point out that when it comes to supplements such as Empower Plus, the evidence points to these doing more harm than good. There are no scientifically rigorous independent randomized controlled trials that show these have any positive effect whatsoever. Furthermore, as they are not regulated by the FDA, they often contain trace amounts of harmful substances such as mercury and other toxins. I would advise against their use.
