Composition

Nitrofurantoin (100 Mg)

Utab 100mg Tablet Sr 10 is an antibiotic used to treat and prevent urinary tract infections (UTIs). It contains nitrofurantoin, which kills bacteria causing the infection. Common side effects include nausea, vomiting, and loss of appetite. It should be taken with food and as directed by a doctor.

It is also used as a preventive measure against recurring UTIs particularly during pregnancy. However, it is important to note that this medicine may not be effective against certain bacteria, such as Proteus or Pseudomonas species.

Consult your doctor for the correct dosage and frequency of this medicine. Before starting this treatment, let your doctor know about any pre-existing conditions or ongoing medications you might have. Report any side effects to your doctor immediately. For optimal results, continue taking the medicine for the duration prescribed by your doctor.

Utab 100mg Tablet Sr 10 is used to treat uncomplicated urinary tract infections (UTIs), including bladder and kidney infections caused by susceptible bacteria. As nitrofurantoin in sustained‑release form, it combats infection by disrupting bacterial DNA in the urinary tract for effective eradication.

Swallow the tablet whole with a glass of water or milk to ease absorption and minimise stomach upset.
Refrain from crushing or chewing the tablet.
Do not exceed the recommended dosage without consulting your doctor.

Utab 100mg Tablet Sr 10 is taken orally.

Utab 100mg Tablet Sr 10 may have the following common side effects:

Anorexia: This refers to loss of appetite, which might make you eat less than usual.
Nausea and vomiting

Headaches
Drowsiness and dizziness
Rash

Managing the Side Effects:

Most side effects are temporary and generally harmless, which resolve on discontinuing the use of Utab 100mg Tablet Sr 10. However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor.

Utab 100mg Tablet Sr 10 contains Nitrofurantoin (100 mg). Here's how it works:

Absorption and Concentration: After you take Utab 100mg Tablet Sr 10 orally, it gets absorbed from your gastrointestinal tract and is concentrated in your urine.
Damaging Bacterial DNA: Nitrofurantoin damages bacterial DNA by inhibiting the synthesis of DNA, RNA, protein, and cell walls.
Production of Reactive Intermediates: Nitrofurantoin also causes single-strand breaks in bacterial DNA by producing reactive intermediates and free radicals.
Resistance Minimization: The multiple mechanisms through which nitrofurantoin acts help minimise the development of resistance by bacteria.

If you are breastfeeding, be aware that the Utab 100mg Tablet Sr 10 should be used with caution. Discuss this with your doctor before starting the medicine.
