What is the H 49 pill used for?
The white oval pill with the imprint H 49 has been identified as Sulfamethoxazole and Trimethoprim 800 mg / 160 mg supplied by Aurobindo Pharma. H 49 pill is used to treat certain bacterial infections, such as pneumonia (a lung infection), bronchitis (infection of the tubes leading to the lungs), and infections of the urinary tract, ears, and intestines. It also is used to treat ‘travelers’ diarrhea.
H49 pill belongs to a class of medications called sulfonamides. It works by stopping the growth of bacteria. Antibiotics will not kill viruses that can cause colds, flu, or other viral infections. Introduced in 1968, Sulfamethoxazole and Trimethoprim remains a popular antibiotic because of its low cost, effectiveness, and familiarity among clinicians. It is one of the most frequently prescribed antibiotics for urinary tract infections in Canada and the United States.
How to use the H 49 pill
Take H 49 pill by mouth, as directed by your doctor, with a full glass of water (8 ounces / 240 milliliters). If a stomach upset occurs, take it with food or milk. Drink plenty of fluids while taking this medication to lower the unlikely risk of kidney stones forming, unless your doctor advises you otherwise. Dosage is based on your medical condition and response to treatment.
The standard adult dose of H 49 pill is 1 every 12 hours for 10 to 14 days. Your doctor may adjust this dose if needed. For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day.
Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping it too early may allow bacteria to continue to grow, which may result in a relapse of the infection. Tell your doctor if your condition persists or worsens.
Will H 49 pill work for a toothache?
Antibiotics like H 49 pill will not cure toothache, they will only mask the problem until you have something done about the tooth itself. They may stop the pain for a few days, weeks, or even months, but it will always come back with a vengeance.
Sulfamethoxazole and trimethoprim combination is used to treat infections including urinary tract infections, middle ear infections (otitis media), bronchitis, traveler’s diarrhea, and shigellosis (bacillary dysentery)
