Brief Answer: As below: Detailed Answer: Hi, Thank you for your query. 1. The feeling of pins and needles is more likely due to the allergic reaction to nitrofurantoin. 2. The dizziness and light headed feeling is likely due to gentamicin, which is a known vestibulotoxic drug. 3. Avoid any antibiotics at present and request a change from Benadryl (which may also cause drowsiness) to a non-sedating anti-allergic combinations such as Allegra and Singulair. It is not possible to predict how long these symptoms would take to recover. 4. Once the allergic reaction subsides, re-evaluate the symptoms of UTI for further treatment options. True drug allergy to all antibiotics is rare, hence there will be antibiotics such as newer generation cephalosporins which you may not be allergic to. Testing, antibiotic challenge or desensitization should be left to the discretion of your physicians. I would recommend indoor admission and close observation. 5. Follow the precautions for prevention of UTI in post menopausal women. This would include hydration, esp. fluids with cranberry juice, frequently emptying the bladder, avoid constipation, wear sterlized loose fitting inner wear and so on. I hope that I have answered your query. If you have any further questions, I will be available to answer them. Regards.

Brief Answer: As belwo: Detailed Answer: Hi, Thank you for writing back. 1. There is no harm in continuing the Benadryl, however, it may be adding to your drowsiness. I suggest that you shift to a no sedating anti-allergic medication. 2. The dizziness and light headedness may also be due to the allergic reactions and the high Gentamicin. 3. It will be better if you get admitted for indoor care and supervision. Your pulse will be high since you have fever. The chills may suggest the persistence of the UTI or a continuing allergic reaction. I hope that I have answered your query. If you have any further questions, I will be available to answer them.
