What happens if you can't have a penicillin shot for syphilis?

What happens if you can't have a penicillin shot for syphilis?

Doxycycline: Doxycycline for 2-4 weeks is recommended if penicillin cannot be given, or sometimes ceftriaxone. However, penicillin is by far the best drug. If you had a severe penicillin allergy in the past, then probably penicillin should be avoided. Otherwise, it still might be the best choice for you. Discuss it with your doctor or, even better, an infectious diseases or STD specialist. ...Read more

Can I take ampicillin if I have an allergy to penicillin? Thanks in advance.

Can I take ampicillin if I have an allergy to penicillin? Thanks in advance.

No: If you are truly allergic to PCN then Ampicillin is closely related. I would recommend seeing an allergist to evaluate your PCN allergy. Many people who think or were told they are allergic actually are not. Even among people who were allergic many lose their sensitivity over time. ...Read more

How come doctors dont prescribe ampicillin to treat syphilis if ampicilin is still penicillin?would it be effetive in treating very early exposure?

Get the shot: Oral penicillins like ampicillin have never been studied against syphilis, and many people wouldn't take it for the 2-4 weeks necessary, especially with usual side effects like diarrhea. Ampicillin soon after exposure probably would prevent syphilis, but there are no data on what dose would be needed. If exposed, you need penicillin by injection. Don't cut corners w/ such a dangerous infection. ...Read more

When my son was little, he took some antibiotic called unasyn (ampicillin and sulbactam). Is that a penicillin?

When my son was little, he took some antibiotic called unasyn (ampicillin and sulbactam).  Is that a penicillin?

Unasyn (ampicillin and sulbactam): Unasyn (ampicillin and sulbactam) is an antibiotic that combines a type of penicillin (called ampicillin) with sulbactam. This drug was developed to deal with bacteria that destroy part of the penicillin chemical structure, thus making these bacteria immune to the antibiotic. The sulbactam inactivates the bacterial resistance, allowing the penicillin portion to be effective. ...Read more

How would you treat a bladder infection from Group B Strep (tested, high number of colonies) that doesn't respond to Ampicillin/Penicillin?

Very unusual: This is almost impossible: GBS is uniformly susceptible to ampicillin and related penicillins. You may need testing to confirm if you are now infected with a different bacteria; and whether you still have a urinary tract infection or some other explanation for your symptoms (e.g., STDs like chlamydia or gonorrhea). Discuss with your doctor. Good luck! ...Read more

I may need cephalosporin therapy with a suspected penicillin allergy.  How does it work?  Do I take a 3rd generation by mouth and sit in an ER waiting room with a buddy and an epipen (epinephrine)?

Penicillin allergy: Among all patients reporting penicillin allergy, 85 to 90% will tolerate a penicillin, either because they were never allergic or because they had an earlier allergy that subsequently resolved. Among penicillin skin test-positive patients, approximately 2% will react to a cephalosporin. ...Read more
