Can I donate blood while on antibiotics?

Can I donate blood while on antibiotics?

No: You have to be in good general health, and if you are on antibiotics, even if feeling better, should not be donating until a few days after you are off of the antibiotics. It is safer for you and the recipient--as may also cause an allergic reaction in the recipient if allergic to the antibiotic meant for you.
Tune up your health a bit first, then call the red cross to set up a donation. ...Read more

Yellow vaginal discharge now turns to blood. I'm taking antibiotics and cream but it gets worst. What should I do?

Yellow vaginal discharge now turns to blood. I'm taking antibiotics and cream but it gets worst. What should I do?

Finish cream: The first step is to finish the medication you are taking. When using vaginal cream it is very difficult to assess vaginal discharge as the cream mixes in and just makes a big mess. After you finish your medication see if the discharge is still there. If so schedule a repeat visit for testing. Yeast infections commonly occur after taking antibiotics ...Read more

My sister's had a fever for 12 days, even after taking antibiotics. All blood tests and chest x-rays are normal. What's going on?

Fever: If she has had documented fever for 12 days and has been unsuccessfully evaluated by a doctor she has what is termed a fever of undetermined origin. She needs to be seen and assessed carefully by an infectious diseases expert. Antibiotics, by the way, will do nothing for a viral illness. ...Read more

Been diagnosed with acute/chronic sinusitis. Taking antibiotics, coughing up thick yellow mucus, now I see traces of blood in the mucus. Should I worry?

Been diagnosed with acute/chronic sinusitis. Taking antibiotics, coughing up thick yellow mucus, now I see traces of blood in the mucus. Should I worry?

Not to worry: Excess mucous during a sinus infection is common and a small amount of blood in the mucous is nothing to worry about. This could be due to your nose drying out or irritation from nose blowing etc. If you have large amounts of bloody mucous or constant bleeding you should see your doctor for evaluation to ensure it is nothing more serious. Feel better soon! ...Read more

I have urinal tract infection. Is it normal to have drops of blood at the end of my urine? I am taking antibiotics given by my doctor now.

Stone? Check w/ MD: Urinary tract infections are uncommon in males. They can bleed but usually do not. I would wonder whether you are passing a stone -- which can predispose to UTI, so you could have both. Let your doctor know about the bleeding and follow his or her advice. ...Read more

Will a blood test show infection if I am currently taking antibiotics (doxycycline)? Is it possible for infection to spread when on antibiotics?

Will a blood test show infection if I am currently taking antibiotics (doxycycline)? Is it possible for infection to spread when on antibiotics?

Yes: It is possible to have an infection while on antibiotics, even possible for that infection to be resistant and untreated by that antibiotics. Cultures may grow more slowly in presence of antibiotics. The blood test may show an indication like an elevated WBC but if the infection is in the blood that would be trouble. ...Read more

Ecoli UTI test of today showed only few bacteries, no blood, while im taking antibiotics (5days) but im having worse strong burning sensation. Wbc is 25

Need a culture: At 5 days you probably need a different antibiotic if it is getting worse. Make sure they do a culture even if the urinalysis is negative. A simple dipstick test is not enough if your having symptoms. That will give you a much better idea of what your dealing with and what antibiotics will work. ...Read more

After taking antibiotics I still have the urge to pee also seeing what's appears to be blood in urine??

After taking antibiotics I still have the urge to pee also seeing what's appears to be blood in urine??

Recheck with doctor: Urine should not have blood in it. A person with "blood" in her urine needs a doctor's evaluation. If one's primary care doctor is not available, her Ob-Gyn doctor may be able to help (an E.R. doctor certainly can help if there is pain, fever, or worse symptoms). There may be a urine infection resistant to the antibiotics already taken, or another problem in the kidneys, ureters, bladder, etc... ...Read more

Here are some...: Your profile of seeing grossly bloody urine & feeling burning voiding should incite an evaluation to assure no UTI, no stone, no tumor (though low odd for the young), etc. How to get those related issues sorted out correctly has not to be hard by following instructions as described in http://formefirst.

After zpack antibiotic use in April. I started using bathroom twice a day diarrhea & seeing blood after wiping from 15-30 times. Today I saw a blood clot on the 1st wipe. No blood in stool. No more blood after first wipe. No pain. What could this be?

Blood on paper: The two main possibilities causing bleeding here are anal fissure or hemorrhoids. See a proctologist or colorectal surgeon for diagnosis and treatment of this nuisance type problem. Of course if ongoing diarrhea continues, consult a gastroenterologist although I doubt serious inflammatory bowel disease is the cause of your symptoms. ...Read more
