Hi - Can I take less than 75mg of Lyrica for shingles? I have too many side effects taking more than 75 mgs. Thanks.

If your doctor prescribed 75mg, then you should take 75mg. You need to take the prescribed amount. If you are having side-effects, then you need to address this with your doctor so that he can prescribe another medication.

NEVER EVER change your medication on your own or via the internet (like here) without consulting your doctor.
