Detailed Answer:
Hi,
Welcome to Healthcare Magic!
Clonazepam,
lorazepam (
Ativan) and
diazepam are all benzodiazepines, with different half-lives. Diazepam is the longest acting, followed by clonazepam and then by lorazepam.
Switching from lorazepam to diazepam would simply reduce the number of tablets you have to take per day, with no other major difference. The only other benefit is that longer acting drugs are associated with lesser risk of dependence as compared to short acting ones, but again, this is not important in your case as you are not planning to continue this medicine for long. You can directly switch from lorazepam to either diazepam or clonazepam, just keeping in mind the equivalent dosages. Roughly 10 mg diazepam = 0.5 mg of clonazepam = 1 mg lorazepam.
You can taper off lorazepam without switching to either diazepam or clonazepam, but you will need to do it slowly. When you reduce every day something you have been taking for weeks, you are going too fast. Just continue on 0.75 mg in morning and 1 mg at night for a week or so, till you notice that you are comfortable on this dose. Then reduce 0.25 mg from the night dose. Again wait for a week or so, followed by a reduction of 0.25 mg from the morning dose. Repeat the process till you stop the medicine completely.
One other thing. I expect you are not having any
withdrawal symptoms on your current dose of lorazepam as it is more than the dose of clonazepam your body was used to. If so, you can try reducing it a bit more to 0.75 mg twice daily and then wait till there are no withdrawal symptoms before reducing further.
The bottom line is:
1) Whichever of the three you choose, taper off very slowly, not every day.
2) The dose that you reduce should depend on how your body reacts. If the withdrawal from reducing 0.25 mg lorazepam per week is more than you can handle, then reduce only 0.125 mg per week or take more than a week. In short, allow your body ample time to adjust. The process should not be uncomfortable, and certainly should not require visits to the ER.
3) Watch for the recurrence of seizures. If you have another seizure even when you are tapering the medicine off very gradually, then it means that you need to be on an anti-epileptic. In that case, you should be shifted on an antiepiletic medicine like
valproate,
phenytoin instead of benzodiazepines.
I hope this clears up things for you. Please let me know if you need any clarifications.
Best wishes.
