Lowri Puw, a 31-year-old pharmacist in Caernarfon - and a member of Welsh Pharmacy Board - said giving more responsibility to pharmacists was "fantastic news", allowing more patients to access UTI medication in a "timely manner, so the infection doesn't get worse".
She recommends calling ahead to make an appointment, to avoid unnecessary trips to the pharmacy.
She said the service was for women only, as UTIs in men are rare - and "if a man does get a bacterial infection, a GP would need to do blood tests to make sure there is no risk of prostate cancer".
And she said it was important to exercise caution around UTI prescriptions for older women.
"As women get older - and if they have more chronic recurrent urinary infections - the infection is more likely to become resistant to the antibiotics that we would normally prescribe.
"So in those cases, the sample would need to be sent off to the microbiology lab before treatment is started - just to make sure that we're treating the right bugs."
"The last thing you'd want is for you to be getting the incorrect treatment, and it gets worse as opposed to being getting better."
However, while welcoming the move to pharmacy care, Ms Puw warned it was essential to "make sure there is funding in place to upskill" staff, adding community pharmacy teams were already "overstretched".
Community Pharmacy Wales is understood to be in "talks with the Welsh government on that front".
