Thru my experience I would have my blood level checked 6mos at my next appointment . By then I would be weaned off of one med and on my new prescribed. Meds.
If the blood levels were still low, my Dr. would increase the meds . Then by the next appointment , and the levels are still low med dosage would get increased again. But if the med levels are at the right level , the meds dosage will stay where they are at.

Generally, any AED that uses the liver or kidneys will need ongoing blood level monitoring.

Which anticonvulsants require blood level monitoring is a great question to ask! Many anti-seizure medications need to stay at a consistent level in the bloodstream to work effectively, which is why blood level monitoring matters.

The anti-seizure medications most commonly requiring regular blood level checks include:

- Phenytoin (Dilantin) – has a narrow therapeutic range and levels can shift significantly with small dose changes
- Carbamazepine (Tegretol) – levels can fluctuate and interact with other medications
- Valproate (Depakote) – especially important due to toxicity risks
- Phenobarbital – long half-life but monitoring helps ensure safe levels
- Lamotrigine (Lamictal) – particularly during dose changes or pregnancy
- Levetiracetam (Keppra) – less critical but sometimes monitored

It's worth noting that how often monitoring is needed varies from person to person. Factors like dose changes, adding new medications, or feeling unwell can all prompt a check.

Always work closely with a neurologist to determine the right monitoring schedule, as skipping doses or inconsistent levels can increase seizure risk.
