Risks far outweigh the benefits according to a clinical
review. NNT for harms is 1 in every 8 taking it. NNT for benefits is 1 in every 18 patients.
It is interesting that pooled studies of subject-declared cures supported the small benefit of antibiotics while those with clinician-diagnosed cures found no benefit, and suggests that a patient-centered approach would endorse a small benefit for sinusitis symptoms in favor of antibiotics. However this benefit comes at a cost. Given that neither the placebo nor antibiotic group found serious adverse events to be a problem, the use of antibiotics to reduce symptoms must be weighed against side effects. Ultimately, this balance has led us to classify this review as ‘Black’: for clinically diagnosed sinusitis the identifiable utility of antibiotics is to reduce respiratory symptoms in a small percentage of patients, while trading this for (arguably more vexing) gastrointestinal symptoms in a larger percentage of patients.I say take it at your own risk, but beware of the long term consequences of doing so. Antibiotics prime the system for further autoimmunity. The delicate balance of good flora has to be preserved somehow to maintain general health. I made a similar mistake a while back of taking amoxicillin and I've regretted it ever since. There was no confirmed infection, and it is something that would have gone away with rest, vitamin C and other alternate treatments.
Best.
