What is penicillin V? What are the uses for penicillin V (phenoxymethyl penicillin)?
- Penicillin V is effective for treatment of laryngitis, bronchitis, pneumonia, and soft tissue and skin infections caused by susceptible bacteria.
- It also is used for preventing recurrence of rheumatic fever and chorea (a disorder of uncontrolled movement of the body).
- Only mild to moderate infections are treated with oral penicillin V.
- Patients with more severe infections are given penicillin by injection.
Is penicillin V (phenoxymethyl penicillin) available as a generic drug?
Do I need a prescription for penicillin V (phenoxymethyl penicillin)?
What are the side effects of penicillin V (phenoxymethyl penicillin)?
Common side effects of penicillin V include:
- abdominal pain,
- black hairy tongue,
- rash, and
Patients with a history of allergic reactions to other penicillins should not receive penicillin V. Persons who are allergic to the cephalosporin class of antibiotics, which are related to the penicillins, for example, cefaclor (Ceclor), cephalexin (Keflex), and cefprozil (Cefzil), may or may not be allergic to penicillins.
Serious but rare reactions include:
- hemolytic anemia,
- super infection,
- reduced kidney function,
- severe allergic reactions (anaphylaxis), and
- low platelet or red blood cell count.
Penicillins can alter the normal bacteria in the colon and encourage overgrowth of some bacteria such as Clostridium difficile which causes inflammation of the colon (pseudomembranous colitis). Patients who develop signs of pseudomembranous colitis after starting penicillin (diarrhea, fever, abdominal pain, and possibly shock) should contact their doctor immediately.
What is the dosage for penicillin V (phenoxymethyl penicillin)?
The usual adult dose of penicillin V is 125 to 500 mg every 6-8 hours.
Which drugs or supplements interact with penicillin V (phenoxymethyl penicillin)?
- Probenecid (Benemid) causes an increase in the level of penicillin in the blood by reducing the elimination of penicillin by the kidneys. In fact, sometimes probenecid is combined with penicillin so that a smaller amount of penicillin results in higher blood levels.
- Penicillin may reduce the effectiveness of BCG live vaccine (used for prevention of tuberculosis) or live typhoid vaccine. Penicillin therapy should be completed before giving live bacterial vaccines.
Is penicillin V (phenoxymethyl penicillin) safe to take if I'm pregnant or breastfeeding?
- Penicillin is considered safe during pregnancy.
- Penicillin is excreted in breast milk and may cause diarrhea or allergic responses in nursing infants. If penicillin is used while nursing, the potential benefit of penicillin for the mother should be weighed against the potential risk of side effects in the infant. Penicillin is used for treating infections in infants.
What else should I know about penicillin V (phenoxymethyl penicillin)?
What preparations of penicillin V (phenoxymethyl penicillin) are available?
Tablets: 250 and 500 mg. Powder: 125 and 250 mg/5 mL.
How should I keep penicillin V (phenoxymethyl penicillin) stored?
- Tablets should be stored between 15 C and 30 C (59 and 86 F).
- After mixing with water, the solution should be kept refrigerated and can be used for up to 14 days after it is reconstituted by the pharmacist.
- It must be shaken before each use and should be kept well-sealed.

STDs can be spread through any type of sexual activity involving the sex organs, the anus or mouth, or through contact with blood during sexual activity. Examples of STDs include, chancroid, chlamydia, gonorrhea, granuloma inguinale, lymphogranuloma venereum, syphilis, genital herpes, genital warts, trichomoniasis, pubic lice (crabs), and scabies. Treatment is generally with antibiotics; however, some STDs that go untreated can lead to death.

Syphilis is a sexually transmitted disease (STD) caused by a spiral-shaped type of bacteria known as a spirochete. There are three stages of syphilis with distinct symptoms. During first stage of syphilis, a painless ulcer known as a chancre forms. Irreversible organ damage can occur during the late stage of syphilis. Special blood tests are used to diagnose syphilis. Syphilis infection is treated with penicillin. Condom use can often prevent syphilis.

Is Strep Throat Contagious?
Strep throat is caused by group A streptococcus bacteria. Incubation period for strep throat is 1-5 days after exposure. If strep throat is treated with antibiotics, it is no longer contagious after 24 hours; if it is not treated with antibiotics, it is contagious for 2-3 weeks. Symptoms include fever, sore throat, tonsillitis, white spots or patches on the tonsils, and nausea and vomiting. Diagnosis of strep throat is performed through a rapid strep test.
Group A streptococcal infections are caused by group A streptococcus, a bacteria that causes a variety of health problems, including strep throat, impetigo, cellulitis, erysipelas, and scarlet fever. There are more than 10 million group A strep infections each year.
Bronchitis (Acute) Contagoius Symptoms, Causes, Treatment, and Recovery Time
Bronchitis is inflammation of the airways in the lung. Acute bronchitis is is short in duration (10 to 20 days) in comparison with chronic bronchitis, which lasts for months to years. Causes of acute bronchitis include viruses and bacteria, which means it can be contagious. Acute bronchitis caused by environmental factors such as pollution or cigarette smoke is not contagious. Common symptoms for acute bronchitis include nasal congestion, cough, headache, sore throat, muscle aches, and fatigue. Acute bronchitis in children also my include runny nose, fever, and chest pain. Treatment for acute bronchitis are OTC pain relievers, cough suppressants (although not recommended in children), and rest. Infrequently antibiotics may be prescribed to treat acute bronchitis.
Strep Throat (Treatment, Causes, Home Remedies)
Strep throat is a bacterial infection of the throat. Signs and symptoms of strep throat include headache, nausea, vomiting, sore throat, and fever. Strep throat symptoms in infants and children are different than in adults. Strep throat is contagious and is generally passed from person-to-person. Treatment for strep throat symptoms include home remedies and OTC medication; however, the only cure for strep throat are antibiotics.
Clostridium Difficile Colitis (Antibiotic-Associated Colitis, C. difficile colitis)
Clostridium difficile (C. difficile) is a bacterium, and is one of the most common causes of infection of the colon. C. difficile spores are found frequently in hospitals, nursing homes, extended care facilities, and nurseries for newborn infants. They can be found: on bedpans, furniture, toilet seats, linens, telephones, stethoscopes, fingernails, rings, floors, infants' rooms, and diaper pails. They even can be carried by pets. Antibiotic-associated (C. difficile) colitis is an infection of the colon caused by C. difficile that occurs primarily among individuals who have been using antibiotics. Treatment for C. difficile colitis includes: hydration, replenishment of electrolyte deficiencies, discontinuing the antibiotic that caused the colitis, and using antibiotics to eradicate the C. difficile bacterium.
Vancomycin-Resistant Enterococci (VRE)
Vancomycin-resistant enterococci (VRE) infection is the most common type of infection acquired by patients while hospitalized. Patients at risk for VRE are those who are already ill, and hospitalized, including individuals with diabetes, elderly, ICU patients, kidney failure patients, or patients requiring catheters. Enterococci can survive for months in the digestive tract and female genital tract. Other risk factors for acquiring VRE include those how have been previously treated with vancomycin and combinations of other antibiotics. Treatment of VRE is generally with other antibiotics other than vancomycin. Prevention of VRE can be achieved by proper hand hygiene.

Yaws is treated with penicillin or another antibiotic.
Antibiotic Resistance (Drug Resistance, Antimicrobial Resistance)
Antibiotics are medications used to kill or slow the growth of bacteria and some fungi. The definition of antibiotic resistance is the ability of bacteria to change (mutate) and grow in the presence of a drug (an antibiotic) that would normally slow its growth or kill it. These antibiotic-resistant bacteria and fungi become harder to treat. Antibiotic-resistant infections can lead to longer hospital stays, higher treatment costs, and more deaths.
