If you or someone in your family has experienced a serious side effect to a health product, you are encouraged to report the experience to your health care professional (e.g. physician, pharmacist). You could also complete a copy of the side effect reporting form or report your side effect to FDA.

Side effects reports are analyzed to discover potential health product safety signals. Some important reactions may take an extremely long time to develop or occur infrequently. Continued monitoring of adverse reactions is thus essential to maintain a comprehensive safety and effectiveness profile of health products.

Antibiotics Side Effects Reported to FDA

The following Antibiotics reports list potential signals of serious risks and new safety information that were identified using the FDA Adverse Event Reporting System (FAERS).
FAERS is a database that contains information on adverse event and medication errors reports submitted to FDA by healthcare professionals (such as physicians, pharmacists, nurses and others), consumers (such as patients, family members, layers and others) and manufacturers.


The appearance of Antibiotics on this list does not mean that FDA has concluded that the drug has the listed risk. It means that FDA has identified a potential safety issue, but it does not mean that FDA has found a causal relationship between the drug and the listed risk.
Pyrexia
This is a report of a 46-year-old female patient (weight: NA) from VE, suffering from the following symptoms/conditions: NA, who was treated with Antibiotics (dosage: NA, start time: Jun 04, 2012), combined with:

Keep Track of Side Effects

Note Your Observations

It is really important to keep of your symptoms, right from the time you start a new medicine. You can do it any way you prefer: in a notebook, in a computer file or using our online tool. You should also note down any other medicines you are taking at the same time, because there could be an interaction between these medicines.

Why Your Notes are Important

Your notes could be helpful in several ways:

  • You can use them to remind you of details that may alert your health care professional(s) to a problem
  • You will have a record to refer to in the future, in case you are ever prescribed the same medicine again

  • Log Form

    You can use the following log form to write down important information, like the date and time you experienced a side effect and your symptoms, how strong the symptoms were, and any other medicines you were using.

    Medicine Name and Dosage:
    Side Effects Scale Date & Time Other Medicine(s) or Treatment(s)
    Scale: 1 = very mild to 10 = very bad

    Multi-Mex Distributor Inc. Dietary Supplements: Recall - Product Packaging Mimics OTC Antibiotics

    [Posted 05/10/2011]

    AUDIENCE: Consumer, Pediatrics

    ISSUE: Multi-Mex Distributor, Inc., recalled dietary supplements that may be labeled as antibiotic drugs. The recall was initiated after an FDA inspection revealed the product packaging mimics antibiotics readily available in Mexico and possibly familiar to Hispanic consumers.

    The products were distributed in the following states: Georgia, Tennessee, California, Illinois, Texas, North Carolina, South Carolina, Colorado, and Indianapolis, to the retail store and distributors.

    BACKGROUND: Warnings of these dietary supplements made news in Texas on Thursday, April 28th, when four children were taken to a Medical Center due to worsening illnesses after being given dietary supplements the parents may have believed were antibiotics and which were packaged to resemble antibiotics that are readily available as over the counter drugs in Mexico. Giving the dietary supplement delayed legitimate medical treatment. Although the labels were printed in English and Spanish, the packaging appears to be an intentional marketing ploy to mimic antibiotics and directed at Hispanic buyers. It was determined the children had been given a dietary supplement, Amoxilina, which the parents may have believed was the antibiotic Amoxicillin.

    RECOMMENDATION: Consumers who have purchased any of the above listed products are urged to return it to the place of purchase for a full refund. Retail stores and distributors are to return the products to Multi-Mex. See the Press Release for listing of  recalled products.

    Healthcare professionals and patients are encouraged to report adverse events, side effects, or product quality problems related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:

    • Complete and submit the report Online: www.fda.gov/MedWatch/report.htm
    • Download form or call 1-800-332-1088 to request a reporting form, then complete and return to the address on the pre-addressed form, or submit by fax to 1-800-FDA-0178
