does valacyclovir work for flu

Recommendations have been issued by the American Society of Regional Anesthesia and Pain Medicine for interventional pain procedures during the current contrast shortage.

Lynn Kohan, M.D., from ASRA, and colleagues developed recommendations for interventional pain procedures during the current contrast shortage, resulting from the shutdown of a production facility in Shanghai.

The authors note that risk stratification should be used to determine which procedures can be delayed until contrast supply resumes. Alternative forms of visualization, such as ultrasound, warfarin sodium 7.5 mg tablet should be considered when feasible. In non-neuraxial injections, the use of gadolinium can be considered. Gadolinium-based contrast agents should not be used in spine-related procedures in the absence or shortage of iodinated contrast medium. Lumbar interlaminar epidural injections, sacroiliac and facet joint injections, lumbar medial branch blocks, and radiofrequency denervation can be performed without use of contrast.
