Product information

Suprax is a brand of antibiotic, made by Sanofi. It is used in the treatment of urinary tract infections when the preferred treatments are not suitable. If you haven’t consulted with a doctor about the first-line treatments (Trimethoprim and MacroBID) you should not order Suprax online and consult about these medications instead.

The NHS estimates that a majority of women in the UK will experience cystitis at least once during their lives. It can affect women of any age, but those who are pregnant, going through the menopause or are sexually active are thought to be more at risk. It occurs when the bladder becomes infected with certain types of bacteria. Resultant symptoms may include inflammation and pain in the bladder, as well as cloudy or discoloured urine.

Cystitis is caused by the transfer of bacteria to the vagina from other sources. This might be through sex, or the use of insertable sanitary or contraceptive devices, or even through certain bathroom habits (which involve the moving of bacteria from the anus to the vagina). A lot of the time, infection is cleared by the body’s natural defences. However, more severe or longer-lasting cases may require treatment.

Bacterial infections are most typically tackled with antibiotics. In the case of Suprax, cefixime is the active ingredient which kills the infection. It does this by attacking the bacteria responsible, and disrupting the protective walls of cells. Once holes begin to emerge in these cell walls, the bacteria become unstable, and susceptible to attack from the immune system.

Treatment for cystitis and urinary infections is not available to buy online from our UK pharmacy. If you suspect you may have an infection, or are experiencing any of the symptoms described above, you should make an appointment with your doctor in person. They will recommend the most appropriate form of treatment, and issue a prescription, where required.

Active Ingredient

Suprax contains an antibiotic agent called cefixime. It is a broad-spectrum medicine. To keep their cell walls intact, bacteria need to produce certain types of proteins. Cefixime works by hindering the release of these proteins, and this in turn creates instabilities and gaps in bacterial cell walls. Once the cells of the bacteria can no longer contain their contents, they become open to attack from the immune system, and begin to die. This then cures the infection.
