How are things going? What did your doctor mention about doxycycline and the esophageal issue? That was really interesting as I never knew how common that was with this medication. Some have long term problems from it and I hope that is not the case with your husband! Please come back and update me!
Hello~I suggest he drink some aloe vera juice, this will help with the burning and also help heal the tissues that could possibly been affected when he took the antibiotic.
Ugh, didn't know about that with doxy! Most antibiotics are recommended to be taken with a full glass of water (also helps cut down on GI distress from it) but never heard of sitting upright for 30 minutes! (sort of a pain, right? Although often antibiotics are good to take with food, again to help prevent GI distress).
Now that you brought this to my attention, I read the statistic of up to 50 percent of those who take doxycycline get esophagitis! Wow! Here's a whole article on it (maybe you have read) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3099275/. The take home from that is that this is common with doxycycline and also that it typically resolves and doesn't become a chronic issue! Here is another article https://www.mayoclinic.org/diseases-conditions/esophagitis/symptoms-causes/syc-20361224.
Would a GERD medication help him? Have you asked your doctor that? I think duration is different for different people but you've eliminated the source of what is causing it so now it is just a matter of recovery time and he is already feeling better which is a good sign.
Let us know how it goes!
