Before Using Amoxil

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Many penicillins have been used in children and, in effective doses, are not expected to cause different side effects or problems in children than they do in adults.Some strengths of the chewable tablets of amoxicillin contain aspartame, which is changed by the body to phenylalanine, a substance that is harmful to patients with phenylketonuria.

Geriatric

Penicillins have been used in the elderly and have not been shown to cause different side effects or problems in older people than they do in younger adults.

Pregnancy

Penicillins have not been studied in pregnant women. However, penicillins have been widely used in pregnant women and have not been shown to cause birth defects or other problems in animal studies.

Breast Feeding

Penicillins pass into the breast milk. Even though only small amounts may pass into breast milk, allergic reactions, diarrhea, fungus infections, and skin rash may occur in nursing babies.

Drug interactions of penicillin

Dessetta: ethinyl estradiol/norethindrone ↔ penicillin v potassium

Antibiotics such as penicillin V potassium may reduce the effects of ethinyl estradiol in some women. If you are using ethinyl estradiol for birth control, you may be at increased risk for pregnancy or breakthrough bleeding.

Achromycin V:Tetracycline ↔ penicillin v potassium

Talk to your doctor before using tetracycline together with penicillin V potassium. Combining these medications may reduce the effectiveness of penicillin V potassium.

Doxycycline ↔ penicillin v potassium

Talk to your doctor before using doxycycline together with penicillin V potassium. Combining these medications may reduce the effectiveness of penicillin V potassium.

Pemetrexed: Alimta ↔ penicillin v potassium

Penicillin V potassium may increase the blood levels and effects of Pemetrexed. You may be more likely to develop serious side effects such as anemia, bleeding problems, infections, and nerve damage when these medications are used together.

Indium oxyquinoline in-111:Amersham Indium (111In) Oxin↔ penicillin v potassium

Treatment with penicillin V potassium can interfere with indium oxyquinoline In-111 test results. Let your doctor know you are on penicillin V potassium if you are scheduled for a indium oxyquinoline In-111 test. It is important to tell your doctor about all other medications you use, including vitamins and herbs.

Clarithromycin ↔ penicillin v potassium

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Anisindione ↔ penicillin v potassium

Using anisindione together with penicillin V potassium may increase the risk of bleeding, especially if you are elderly or have kidney or liver impairment.

Balsalazide ↔ penicillin v potassium

Talk to your doctor before using balsalazide together with penicillin V potassium. Antibiotics like penicillin V potassium may reduce the effectiveness of balsalazide when taken orally.

Coumadin:Warfarin ↔ penicillin v potassium

Using warfarin together with penicillin V potassium may increase the risk of bleeding, especially if you are elderly or have kidney or liver impairment.

Methotrexate↔ penicillin v potassium

Methotrexate sodium oral increases levels of penicillin v potassium by reducing drug clearance through the kidneys.

Penicillins Disease Interactions

(1)Beta-Lactams (Parenteral) (Includes Ampicillin) ↔ Renal Dysfunction

Most beta-lactam antibiotics are eliminated by the kidney as unchanged drug and, in some cases, also as metabolites. The serum concentrations of beta-lactam antibiotics and their metabolites may be increased and the half-lives prolonged in patients with impaired renal function. Neurotoxic reactions, including encephalopathy, asterixis, myoclonus, seizures and coma, have been reported in such patients treated parenterally with these agents.

(2)Aminopenicillins (Includes Ampicillin) ↔ Mononucleosis

Patients with mononucleosis treated with an aminopenicillin antibiotic, particularly ampicillin, quite frequently develop a pruritic erythematous maculopapular skin rash that generally occurs 5 to 10 days after therapy is initiated.

(3)Ampicillin↔: Congestive Heart Failure, Fluid Retention, Hypertension, Hypernatremia

Parenteral ampicillin sodium contains approximately 67 to 71 mg of sodium per each gram of ampicilliin activity The sodium content should be considered when these products are used in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.

(4)Antibiotics (Includes Ampicillin) ↔ Colitis

Pseudomembranous colitis has been reported with most antibacterial agents and may range in severity from mild to life-threatening, with an onset of up to two months following cessation of therapy. Antibiotic therapy can alter the normal flora of the colon and permit overgrowth of Clostridium difficile, whose toxin is believed to be a primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe, persistent diarrhea and severe abdominal cramps, and may be associated with the passage of blood and mucus

(5)Penicillins (Includes Ampicillin) ↔ Hemodialysis

Penicillin antibiotics (except for agents in the penicillinase-resistant class) are removed by hemodialysis. Doses should either be scheduled for administration after dialysis or a supplemental dose is given after dialysis.
