Is honey good for a baby with a cough?

Thanks for the question. Please call your pediatrician or nurse.

Got the Covid vaccine too soon?

Thanks for the question. We generally ask you to wait 90 days after a covid infection to receive the vaccine. Your respiratory symptoms should be investigated by your doctor. There is no guidance scientifically about what to do further about too early a vaccine, or if it can induce respiratory symptoms if given too early. It would be worth a direct inquiry to Pfizer or Moderna. I have made an inquiry, and no one is willing to speculate about this question, as there is no data.

I don’t want to get the vaccine?

Thanks for your question. There are no studies concerning fertility rates in vaccinated women or men. That makes it impossible to make a recommendation. We do know that receipt READ MORE
Thanks for your question. There are no studies concerning fertility rates in vaccinated women or men. That makes it impossible to make a recommendation. We do know that receipt of the vaccines during pregnancy does not increase the rate of fetal abnormalities. Use your best judgment, but understand that the larger the number of unvaccinated people, the less the chance of achieving herd immunity, which would allow the easing of restrictions. Google studies periodically to see if any fertility studies are available.

Second covid-19 shot?

Thanks for the question. If the symptoms are due to the vaccine, and not an unrelated stomach virus, they should resolve in a few days. If they don't, please call your doctor. READ MORE

Thanks for the question. The Astra-Zeneca vaccine is approved for release in Europe, but not in the United States. A very small percentage of recipients developed disseminated clotting with no other underlying explanation. I would personally recommend the other vaccines, but that is strictly a personal preference. So far, they have been safe, but no one knows if there would be any long term effects of any of the vaccines.

Penicillin allergy vs the covid-19 vaccine?

It is safe to take the vaccine, unless you have a history of reaction to other vaccines or to polysorbate. Penicillin allergy has no effect on vaccine tolerance. Thanks for READ MORE

Yes. Thanks for the question. Dupixent inhibits two Inflammatory mediators which are not necessary for response to the vaccine, but there is no study showing any interaction. When uncertain, it is best to wait 14 days after the vaccine before taking any possible interacting drugs.

Taking different antibiotics simultaneously?

Thanks for your question. The two meds do not interact, but the Doxycycline should not be taken less than 2 hours after eating anything dairy or anything with Calcium or Magnesium, READ MORE
Thanks for your question. The two meds do not interact, but the Doxycycline should not be taken less than 2 hours after eating anything dairy or anything with Calcium or Magnesium, and wait two hours after taking it before consuming those things. Doxycycline can also cause a skin rash after sun exposure in up to 25% of people. Probiotics are a bit of a problem when taking antibiotics that can destroy the bacteria in them, so I would take them late at night, 2 hours or more after your last dose. Most probiotics are not particularly effective, but you can try Kefir or a brand with Bifidobacterium.

Should I wear the black bandana?

Yes.
