Is HEADACHE a side effect of CLARITHROMYCIN ? ( FactMed.com )

About this FactMed analysis covering adverse side effect reports of CLARITHROMYCIN patients who developed HEADACHE.

FactMed provides MD-approved analysis to help both patients, researchers, and physicians accurately assess the risk profile for more than 20,000 different pharmaceutical products. The below report offers compiled information from Food & Drug Administration and FactMed user submissions. Between January 2004 and October 2012, 281 individuals taking CLARITHROMYCIN reported HEADACHE to the FDA. A total of 10851 CLARITHROMYCIN drug adverse event reaction reports were made with the FDA during this time period. Often the FDA only receives reports of the most critical and severe cases; these numbers may therefore underrepresent the complication rate of the medication.

FDA Research Report

Introduction This page is designed to help you determine the relationship, if any, between CLARITHROMYCIN and HEADACHE. In doing so, we compare CLARITHROMYCIN with other drugs that cause HEADACHE, to help you evaluate whether or not CLARITHROMYCIN causes HEADACHE. Likewise, this page shows the most highly-reported side effects of CLARITHROMYCIN, so you can see if HEADACHE ranks among CLARITHROMYCIN's most well-known side effects.

QUESTION AGEUSIA	Could there be a relationship between Infectious mononucleosis, clarithromycin and ageusia? Can someone help? My 18 year old son initially diagnosed with tonsillitis took cephalexin then clarithromycin for 9 days before being diagnosed with infectious mononucleosis. He was very very sick. At the end of week 2 of (IM) he was hospitalised for 5 days to manage pain (throat), fluids and monitor his splenomegaly (diagnosed via palpating and abdominal US) and abnormal liver function. He returned home in week 3, during which he developed a significant body rash worse on the torso and on the limbs proximally, his physician believes as a result of the interaction between the virus and the antibiotics. After 7 days the rash had virtually disappeared but over a few hours he then developed ageusia, initially he complained of a metallic taste but that disappeared over a few days. It is now 16 days after developing ageusia, with no change in his ability to taste yet. He has no other symptoms, and appears to be making a good recovery from IM otherwise. Can someone help? He is only 18 and is quite distressed by this. Thank you.	2015-04-06 02:39:29

QUESTION NEURALGIA	I was prescribed 500mg Clarithromycin bds last week after having an unpleasant ?flu virus for over a week. I'm 80yrs old.

I'm still experiencing unpleasant neuralgia in the left side of my face - from my t.m.joint tracking the jaw line and into my teeth.
