EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Commercially available ... penicillin V potassium tablets and powders for oral suspension or solution should be stored in tight containers at 15-30 °C. Following reconstitution, penicillin V potassium oral solutions should be refrigerated at 2-8 °C and any unused solution should be discarded after 14 days.

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Mixing penicillins with aminoglycosides in vitro has resulted in substantial mutual inactivation; if these groups of antibacterials are to be administered concurrently, they should be administered at separate sites at least 1 hour apart. /Penicillins/

Concurrent of /methotrexate/ with penicillins has resulted in decreased clearance of methotrexate and in methotrexate toxicity; this is thought to be due to competition for renal tubular secretion; patients should be closely monitored; leucovorin doses may need to be increased and administered for longer periods of time. /Penicillins/

Since bacteriostatic drugs /Chloramphenicol, erythromycins, sulfonamides, or tetracyclines/ may interfere with the bactericidal effect of penicillins in the treatment of meningitis or in other situations in which a rapid bactericidal effect is necessary, it is best to avoid concurrent therapy; however, chloramphenicol and ampicillin are sometimes administered concurrently to pediatric patients. /Penicillins/

Probenecid decreases renal tubular secretion of penicillins when used concurrently; this effect results in increased and prolonged serum concentrations, prolonged elimination half-life, and increased risk of toxicity. Penicillins and probenecid are often used concurrently to treat sexually transmitted diseases or other infections in which high and/or prolonged antibiotic serum and tissue concentrations are required. /Penicillins/

A double blind, randomized study was undertaken in 52 children to compare the bacteriological efficacy and safety of oral sultamicillin (iosylate (I) to those of oral penicillin V potassium (II) in the treatment of childhood streptococcal pharyngitis for a period of 10 days. The dosage was determined by age & weight: patients under 5 yr were given 125 mg/dose and patients over 20 kg, 375 mg/dose. Recolonization did not occur in the II group. Adverse effects were self-limited. One child receiving II developed an elevated serum transaminase level.

Two patients (aged 24 and 34 yr) with penicillin V potassium induced anaphylaxis experienced cardiac disorders immediately after 5 ml of 1:10,000 epinephrine chloride (I) admin by slow IV. Within sec after the injection, ventricular premature beats and apparent accelerated idioventricular rhythm occurred in one patient and possible ventricular tachycardia occurred in the other. It was concluded that patients during anaphylaxis should be monitored and the potential hazards of admin I by IV route in this clinical setting should be emphasized.

However, seizures, myoclonus, and problems with mentation and level of consciousness have been reported, particularly with penicillins. Most often this toxicity is seen in the setting of renal failure, which may allow drug accumulation. The precise mechanism responsible for these neurologic side effects is unclear, but it is known that direct application of penicillin to the brain is associated with seizures. /Penicillins/

In an epidemiologic study from Sweden, about half the cases of pseudomembranous colitis were associated with penicillins, about one third with cephalosporins, and about 14 percent with lincosamides (mostly clindamycin), reflecting the more frequent use of the penicillins and cephalosporins. The clustering of cases in some studies has suggested possible nosocomial transmission of C. difficile. /Penicillins and cephalosporins/

... Conclusions: Under the conditions of these 2-year gavage studies, there was no evidence of carcinogenic activity of penicillin VK for F344/N rats or for B6C3F1 mice administered 500 or 1,000 mg/kg penicillin VK in corn oil gavage, 5 days per week for 2 years. ... Decreased survival of low and high dose male rats and of high dose female rats reduced the sensitivity of the studies for determining the presence or absence of a carcinogenic response in this species.
