Antibiogram: Those results seem to be from an antibiogram. This study says which bacteria grew up on the culture test and its sensivity (S) or resistance (R) to some antibiotics. This test is helpful to select the best available antibiotic treatment. It is important to speak out your thoughts to your doctor for having the best interpretation about this results, since these depend of the specific situation.

A 40-year-old member asked:

How can I prevent inflammation of stomach lining due to blood thinner plavix (clopidogrel)?

Take with food: Do not take the medicine on an empty stomach and it sometimes is helpful to take medicines such as antacids that are used to treat gastritis. Many people can take Plavix (clopidogrel) without problems. Some of the medications can interfere with the action of the Plavix (clopidogrel) so consult your physician.

They shouldn't: Those are not usual side effects from any antibiotic therapy, speak with your prescribing doctor about it.

No: Not a wise combination. Can decrease the efficacy of Lisinopril and increase the incidence of kidney toxicity.

Have had burning pain when urinating, comes and goes. Was on an antibiotic....Never seems to go completely away.?

Many reasons: Urethritis is inflammation of the urine tube going through the penis. If inflammed due to infection, antibiotics should take care of it. If due to chemical irritation, the antibiotics will not. Trauma can cause irritation. You may need more time. If there is a discharge, you may need to be seen again. If concerned, seek re-evaluaiton.

How long should I wait to take breath test for h. Pylori after 7 day antibiotic treatment? (antibiotics: tetracyline, omeprazole, metronidazole)

When you are ready?: I usually judge a patients progress by their symptoms; if after the course of treatment your symptoms have subsided then there is no real need for repeating the breath test. However, if you are being sent for it, then ask your doctor when you should go; i see no harm in undergoing the test the day or two after you have taken the last of the treatment.

Blood test USELESS in this scenaroi. imaging you had measles as a kid - your blod test will still be positve - but you don't have the disease... similarly, a positive antibody test, tells you nothing post-treatment.

Actually, with either the breath test or the stool test, you should be off antibiotics for at least a month before doing the test. As Dr. Huilgol stated, avoid the blood test.
