Amoxicillin Trihydrate: Brands, Price & Uses in Bangladesh

Respiratory Tract and ENT Infections

Amoxicillin Trihydrate is an established, FDA-approved treatment for infections of the ear, nose, and throat (including acute otitis media, sinusitis, tonsillitis, and pharyngitis) and for lower respiratory tract infections such as bacterial bronchitis and community-acquired pneumonia caused by susceptible, non-beta-lactamase-producing organisms including Streptococcus pneumoniae, Haemophilus influenzae (non-beta-lactamase-producing strains), and Streptococcus pyogenes.

Genitourinary Tract Infections

Amoxicillin Trihydrate is established therapy for uncomplicated urinary tract infections caused by susceptible E. coli, Proteus mirabilis, and enterococci, and, at high single-dose regimens combined with probenecid, for uncomplicated gonorrhea (where locally supported by susceptibility data; ceftriaxone-based regimens are now preferred first-line therapy in most current guidelines because of resistance).

Skin and Soft Tissue Infections

Amoxicillin Trihydrate is an established treatment for skin and skin-structure infections caused by susceptible, non-beta-lactamase-producing staphylococci and streptococci.

Helicobacter pylori Eradication

Amoxicillin Trihydrate is guideline-supported therapy for H. pylori eradication in peptic ulcer disease, but only as part of combination regimens with a proton pump inhibitor and clarithromycin (triple therapy) or with a proton pump inhibitor alone at higher, more frequent dosing (dual therapy); Amoxicillin Trihydrate is never used alone for this indication because monotherapy does not reliably eradicate H. pylori and promotes resistance.

Dental Infections

Amoxicillin Trihydrate is commonly used, and supported by dental practice guidance, as short-term therapy for odontogenic (dental) infections and as antibiotic prophylaxis before certain dental procedures in patients at high risk of infective endocarditis, per American Heart Association guidance.

Anthrax Post-Exposure Prophylaxis and Treatment (Adjunct/Alternative Use)

Amoxicillin Trihydrate is a CDC-recognized alternative agent for post-exposure prophylaxis following confirmed susceptible Bacillus anthracis exposure, and for continuation therapy after initial treatment, used under public-health or specialist direction rather than as routine outpatient therapy.

The dose, frequency, and duration of Amoxicillin Trihydrate depend on the specific infection being treated, its severity, the causative organism (where known), and the patient's age, weight, and renal function. The regimens below reflect commonly cited, guideline- and label-based dosing and must be individualized by a qualified healthcare professional; the dosing used for one indication is not necessarily appropriate for another.

Common Side Effects

• Diarrhea, nausea, and vomiting
• Indigestion or abdominal discomfort
• Skin rash (including a common, non-allergic, maculopapular rash that can occur when Amoxicillin Trihydrate is given to patients with underlying infectious mononucleosis — see Precautions and Warnings)
• Headache

Serious Side Effects (Seek Medical Attention)

• Signs of a severe allergic reaction, such as swelling of the face, lips, tongue, or throat, difficulty breathing, or anaphylaxis
• Severe, persistent, or bloody diarrhea, which may indicate Clostridioides difficile-associated diarrhea or colitis, and can occur even weeks after stopping Amoxicillin Trihydrate
• Severe skin reactions such as blistering, peeling skin, or widespread rash (possible Stevens-Johnson syndrome, toxic epidermal necrolysis, or DRESS syndrome)
• Yellowing of the skin or eyes, dark urine, or unusual tiredness, which may indicate liver injury (hepatitis or cholestatic jaundice)
• Unusual bruising, bleeding, or signs of a blood disorder
• New or worsening seizures, which have rarely been reported, particularly with high doses or in patients with renal impairment
