Identifying the Pink Pill with Imprint 'A 6 7'
The pink, capsule-shaped pill marked with 'A 6 7' is identified as Amoxicillin Trihydrate at a strength of 875 mg [1.2.1, 1.2.2]. Amoxicillin is a widely used antibiotic belonging to the aminopenicillin class of drugs, which is a type of penicillin [1.2.1, 1.4.1]. It is available only with a doctor's prescription and is used to treat infections caused by susceptible bacteria [1.8.4]. It is important to note that antibiotics like amoxicillin are not effective against viral infections such as the common cold or flu [1.2.3].
How Amoxicillin Works: The Mechanism of Action
Amoxicillin is a bactericidal antibiotic, meaning it works by directly killing bacteria [1.4.3]. Its mechanism of action involves interfering with the synthesis of the bacterial cell wall [1.4.2]. Bacteria are protected by a rigid outer layer called a peptidoglycan cell wall. Amoxicillin works by binding to specific proteins, known as penicillin-binding proteins (PBPs), which are essential for building this wall [1.4.2]. By inhibiting these proteins, amoxicillin disrupts the cell wall's construction, leading to the breakdown (lysis) of the bacterial cell and its eventual death [1.4.2, 1.4.3]. This action is effective against a broad spectrum of gram-positive and some gram-negative bacteria [1.4.1]. However, some bacteria produce enzymes called beta-lactamases, which can inactivate amoxicillin. In such cases, amoxicillin may be combined with a beta-lactamase inhibitor like clavulanic acid to overcome this resistance [1.4.2].
What Is the Amoxicillin Pink Pill 67 Used For?
The 875 mg dose of amoxicillin is prescribed for a variety of common bacterial infections [1.2.1]. A healthcare provider determines the appropriate use based on the type and severity of the infection. Common uses include:
- Respiratory Tract Infections: It is frequently used for lower respiratory infections like pneumonia and bronchitis, as well as upper respiratory infections affecting the ears, nose, and throat, such as otitis media (ear infection), pharyngitis (sore throat), and sinusitis [1.2.3, 1.3.1].
- Skin Infections: Amoxicillin is effective against certain bacterial skin infections, like cellulitis [1.3.1].
- Urinary Tract Infections (UTIs): While not always the first choice due to potential resistance, amoxicillin can be used to treat UTIs if the causative bacteria is known to be susceptible [1.3.1].
- H. pylori Eradication: In combination with other medications like clarithromycin and a proton pump inhibitor (e.g., lansoprazole), amoxicillin is used to treat stomach ulcers caused by the bacteria Helicobacter pylori [1.2.3, 1.8.4].
- Other Infections: It can also be used for conditions like gonorrhea, Lyme disease, and to prevent anthrax infection after exposure [1.2.3, 1.3.4].
Proper Dosage and Administration
Amoxicillin 875 mg is typically taken every 12 hours (twice a day) [1.8.4]. It's crucial to take the medication exactly as prescribed by your doctor and to complete the entire course of treatment, even if you start to feel better [1.8.1]. Stopping the antibiotic too soon can lead to the infection not being fully treated and may contribute to the development of antibiotic-resistant bacteria [1.8.1].
Amoxicillin can be taken with or without food, but taking it with a meal can help reduce stomach upset [1.8.1, 1.8.4]. Patients should take the pill at evenly spaced intervals to maintain a consistent level of the drug in their system [1.11.4]. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and resume your regular schedule. Do not take a double dose to make up for a missed one [1.11.2, 1.11.3].
Potential Side Effects and Warnings
Like all medications, amoxicillin can cause side effects. It's generally well-tolerated, but some common side effects include:
- Nausea and vomiting [1.2.3]
- Diarrhea [1.2.3]
- Rash [1.3.1]
- Changes in taste [1.3.1]
Taking the medication with food can help lessen digestive side effects [1.3.1]. While most side effects are mild, some can be serious and require immediate medical attention. These include signs of a severe allergic reaction (hives, difficulty breathing, swelling of the face, lips, tongue, or throat), severe skin reactions (blistering or peeling skin), and severe, watery, or bloody diarrhea, which can occur up to two months after treatment and may be a sign of a C. difficile infection [1.2.3, 1.3.1].
Important Warnings:
- Allergies: Do not take amoxicillin if you have a known allergy to penicillin or cephalosporin antibiotics [1.2.3, 1.3.5].
- Mononucleosis: Patients with mononucleosis ('mono') have a high risk of developing a skin rash when taking amoxicillin and should avoid it [1.3.4, 1.5.2].
- Kidney Disease: Patients with severe kidney problems may require a lower dose, as the drug is primarily cleared by the kidneys [1.3.4, 1.8.3].
- Drug Interactions: Amoxicillin can interact with other medications, including blood thinners (like warfarin), gout medications (allopurinol, probenecid), and methotrexate [1.3.4, 1.5.1]. It may also decrease the effectiveness of oral contraceptives, so an alternative birth control method is recommended during treatment [1.2.3, 1.3.2].

Conclusion
The amoxicillin pink pill marked 'A 6 7' is a high-dose (875 mg) formulation of a powerful and widely used penicillin antibiotic [1.2.1].
