I was on seizure medicine for 20+ years and I’m just wondering about long-term effects.

Yes, there is research on the long-term effects of anti-seizure medications (ASMs), and it's a really important question — especially after 20+ years of use. The effects can vary depending on which medication(s) were taken.

Yes, there is research on the long-term effects of anti-seizure medications (ASMs), and it's a really important question — especially after 20+ years of use. The effects can vary depending on which medication(s) were taken.

Here are some known long-term concerns that have been studied:

- Bone health — Some older medications like divalproex sodium (Depakote), phenytoin, primidone, phenobarbital, and carbamazepine are linked to reduced bone density over time
- Liver and kidney function — Certain ASMs can affect these organs with long-term use, which is why regular monitoring is often recommended
- Blood cell counts — Some medications may affect blood cell production over time
- Mood and cognition — Long-term use can impact memory, focus, and emotional wellbeing for some people It's worth noting that newer medications like levetiracetam (Keppra), topiramate, and zonisamide may carry different long-term risks compared to older ones — and some newer drugs are still being studied.

The best step would be talking with a neurologist who can review the specific medication(s) taken and recommend any follow-up monitoring, like bone density scans or blood work, based on that history.

@A MyEpilepsyTeam Member , I have been on Depakote for probably just over 25 years & long term use has caused Osteopenia in my left hip. I’m still taking Depakote but am now taking Vitamin D every other day, along with the Multivitamin that I have been taking for years. My Neurologist has ordered another bone density test & so I have that coming up in several months. One Neurologist made me aware that long term use can possibly cause Osteoporosis & had me do a bone density test & that’s when we found out about the Osteopenia. Good luck.

Hi there I’ve been on Tegretol for 40 years and would love to change to another newer drug. All I hear is terrible things about Tegretol but what is similar to it to ask my doctor.

generally, research into the meds works long term any way so even though a med may come and they have done all the testing and research they need to technically its still classed as new for about 30 years. If a med is that old, then they should have that research on the med. I know Tegretol is one that is not good long term due to liver issues.

Ive been on meds for 60 years. Tegretol got me nearsighted. Beware of Gabapentin. I hear its causing amputations.
