It depends. Many types of antibiotics must be refrigerated and used before the expiration date. It may lose strength and be ineffective so it's best to discard unrefrigerated and/or expired medicine.
A horse should be given penicillin when a veterinarian determines the horse has a bacterial infection that will respond to the penicillin.
This will depend upon how "out of date" the penicillin is, how it has been stored and if the seal on the bottle has been breached. Penicillin is a fairly cheap drug, so when in doubt I suggest simply purchasing a new bottle if needed.
Yes, penicillin can cure boils. The penicillin usually given for boils is Flucloxacillin. If a person is allergic to penicillin, they will be given a different antibiotic.
If you are talking about WWI trenches, given that penicillin was discovered in 1938, no, it did not help
Yes, most injectable penicillin formulations are designed to be given intramuscular.
The miracle drug
they died
1. Probenecid inhibits the tubular secretion of penicillin thus increasing the serum concentration of penicillin. 2. Lesser dose of Penicillin is needed 3. Therefore, there will be less side effects of penicillin.
Penicillin has very large margin of safety. Usual adult dose of procaine penicillin is 600,000 I.U. (International units) per day. The adult dose of penicillin can be given up to 24 million I. U. of crystalline penicillin per day in meningitis. The first dose of penicillin, that was given to the patient as trial dose was only 5000 I.U. few times per day. It was given during second world war. The most wonderful thing that this small dose did work. The patient started to improve. Later on died of infection, only because the stock of penicillin got exhausted.
It should be given in the muscle.
