Aminoglycoside antibacterial is a pharmacologic class (an FDA Established Pharmacologic Class) with 15 drug pages on this site. Together those drugs are listed as a suspect or interacting product in 37,840 adverse event reports received by FDA, 0.2% of the database, from January 2004 to June 2026.

2,631 reports arrived in the 12 months to June 2026, down 18% from 3,203 in the 12 months before. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. 80.3% of the class's reports are marked serious, 17.3% record death among the outcomes and 41.5% record hospitalisation, as reported.

Across the class the reactions recorded most often are off label use (10.8%), drug ineffective (9.7%) and dyspnoea (8%). The class median share shown beside each term is the middle value across the member drugs; it is the comparison used on every drug page in this class.

The members table is ordered by report count for navigation only. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic."

Questions about Aminoglycoside antibacterial reports

Which drugs are in the Aminoglycoside antibacterial class on this site?

Arikayce, Gentamicin, Amikacin, Tobramycin, Tobi and TOBI Podhaler and 9 more. Class membership comes from the pharmacologic class (EPC) on the drug's FDA label.

How many reports does the class have?

37,840 reports through June 2026, 2,631 of them in the latest 12 months. A report listing two drugs of the class counts once for each.

What reactions are recorded most often?

off label use (10.8%), drug ineffective (9.7%), dyspnoea (8%), cough (7.1%) and death (6.7%).

Can the members table be used to rank the drugs?

No. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic." Drugs differ in how many people take them, in the conditions they treat, in time on the market and in how diligently reports are collected.

How do I report an adverse event?

Through FDA MedWatch (Form FDA 3500, or 1-800-FDA-1088) or to the manufacturer. See the guide on how to report.

Where this comes from. Counts are built from the openFDA Drug Adverse Event (FAERS) bulk export released 28 Sep 2026, which holds reports FDA received through 30 Jun 2026. Drug names are as reported, resolved to the brand or generic name on the FDA label where openFDA's harmonisation matched them; classes are the pharmacologic class (EPC) from the label and the National Drug Code Directory of 17 Sep 2026. A class is the Established Pharmacologic Class most often attached to a drug's reports by openFDA's label harmonisation, or from the NDC Directory where reports carry none. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
