Penicillin Overview

Penicillin (PCN or pen) is a group of antibiotics which include penicillin G (intravenous use), penicillin V (use by mouth), procaine penicillin, and benzathine penicillin (intramuscular use). Penicillin antibiotics were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci.

penicillin ## I have recently been prescribed Penicillin Vk 500 mg from a doctor. I was in SO much pain from my peridontal disease,(from my infection under my teeth), that the pain was excruciating. i went to an emergency hospital instead of a dentist.

Is Gimalxina Amoxicilina 500 mg from Mexico Counterfeit? i.e. Placebo?
10 Replies RSS
I have taken amoxicilina many times during my life; bought in the US and in Honduras. This last week I got a bottle of 60 capsulas while in Cozumel, to complete my antibiotic treatment (I lost the previous amoxi I was taking). I am very familiar with the smell and taste of amoxicilina and penicillin. I open the capsules when I take it, it tastes bad, and has a unique taste & smell (also in urine). The current bottle I just purchased, red & white capsulas, is a white powder with NO taste nor smell. Furthermore, it appears to have no affect on my sinusitis, and NO odor in urine. This is the first Amoxi I have ever taken that is like this (no taste & no odor. So common sense tells me I HAVE BEEN ROBBED. If this is COUNTERFEIT Amoxi, we need to STOP ITS SALE. The bottle I have s...

Using expired penicillin
2 Replies RSS
I have a bad tooth that hurts and I have some penicillin that expired 6-24-2013 from a dentist. Would it be safe to take? ## Hello, Marty! How are you? This medication does not become dangerous, once expired, but it does start to lose effectiveness, thus it may not fully eradicate infectious bacteria, which creates the risk of it developing antibiotic resistance. Thus, it would be best to see your dentist, so they can prescribe a fresh supply, if an antibiotic is necessary. The FDA lists the typical antibiotic side effects as possibly including nausea, dizziness, headache, non-allergic skin rash and diarrhea. Is there anything else I can help with? ## My meds say to discard after 5/3/17 and they're Penicillin vk. It is 11/2/17. Can I still take them?

Can i take pota-vi-kin penicilina v tablets 400,00 u for chest congestion? ## Penicillin is an antibiotic, so it will only help treat infections. If your congestion is caused by a virus, such as the cold or flu, it will not help. It will also not help if it is caused by allergies. In addition, using it inappropriately creates the danger of developing antibiotic resistant bacteria.

hispanic antibiotic penicillin substitue??? ## what is ampitrexyl for ## Hi, I've been ill with cough and sore throat symptoms so far the medication that I've been taking has somewhat reduced it, but doesn't go away.
