Alcohol and Antibiotics: Understanding Risks and Interactions

What are antibiotics made of? Penicillin's discovery in 1928 marked the start of a golden era in finding natural antibiotics, peaking in the 1950s.

New cephalosporin-lactamase inhibitor combinations also approved include ceftazidime-avibactam and ceftolozane-avibactam for complicated urinary tract infection and intra-abdominal infection.

Alcohol did not affect the efficacy of ceftriaxone in a pneumonia model; survival rates were similar in alcohol-fed and control rats (13).

The first sulfonamide and the first systemically active antibacterial drug, Prontosil, was developed by a research team led by Gerhard Domagk in 1932 or 1933 at the Bayer Laboratories of the IG Farben conglomerate in Germany. Synthetic antibiotic chemotherapy as a science and the development of antibacterials began in Germany with Paul Ehrlich in the late 1880s.

Trimethoprim-sulfamethoxazole (TMP-SMX) is used for urinary tract infections and pneumocystis infections (74). Two authors observed higher rates of side effects in patients treated with metronidazole than with placebo (64, 65). The package labeling recommends against the use of metronidazole and alcohol within 48 h due to the risk of a disulfiram-like reaction (46). Nitroimidazoles are used for parasitic or anaerobic infections (45). Data are limited regarding the adverse effects of concomitant use of FQs and alcohol.

Clinicians have recommended that extra contraceptive measures be applied during therapies using antibiotics that are suspected to interact with oral contraceptives. Situations that may increase the risk of oral contraceptive failure include non-compliance (missing taking the pill), vomiting, or diarrhea. The majority of studies indicate antibiotics do not interfere with birth control pills, such as clinical studies that suggest the failure rate of contraceptive pills caused by antibiotics is very low (about 1%). There are few well-controlled studies on whether antibiotic use increases the risk of oral contraceptive failure. Antibacterials can also affect the vaginal flora, and may lead to overgrowth of yeast species of the genus Candida in the vulvo-vaginal area.
