Q & A

Chlamydia is a sexually transmitted infection. It is caused by a bacteria known as Chlamydia Trachomatis. In females, this condition usually affects the cervix and the womb. Whereas in men, it affects the pipe through which urine passes in the penis (urethra). Chlamydia can also infect the eye and lungs. However, it is a treatable condition. It is predicted that approximately 10% of all those under the age of 25 will be infected. It is highly recommended that if you are 24 years of age or below and are sexually active, you should test yourself yearly (or more frequently if you feel the need) or every time you have a new sexual partner. You can also contract Chlamydia if you come in contact with the semen or the vaginal fluid of the infected person.

Erythromycin is an antibiotic. It is used for short-treatment of bacterial infections such as Chlamydia. The name of the medicine is Erythrocin. It contains an active substance Erythromycin. This medicine can be taken by adults and children. It helps by killing the germs which cause the infection. Erythromycin is available as tablets, capsules, and oral liquid medicine.

Is chlamydia a treatable condition?

YES. Chlamydia is a treatable condition. Symptoms are not visible in most cases. Hence, go for a regular health check-up. If not treated, this condition can cause serious and permanent damage to the reproductive systems.


How would I know if I have chlamydia?

Some people will see absolutely no symptoms whatsoever, so the only way to receive a definite diagnosis is through taking a test. Chlamydia tests can be bought from select stores or ordered online.


If I had symptoms which have now passed, does it mean the infection has passed?

Your body cannot eradicate chlamydia on its own, so it is not safe to assume this. Symptoms can quite often fade despite the infection still remaining present. You could still be affected and at risk of passing it on.


Can I repeat the chlamydia test after taking and finishing my treatment?

YES. There is no danger in doing so. However, it takes approximately 6 weeks for the test to begin to show as negative after an infection. If you are to take a re-test too early, a positive result could cause a scare and point to signs of a continuing infection. It is, however, most likely just showing as positive from the initial infection.


How can chlamydia be prevented?

The best way you can avoid the spread of STDs is to quite simply not engage in sex. Failing that, having sex with the same partner who you know has been tested and is uninfected is just as effective. Male condoms, if used correctly every time, can dramatically reduce the chances of contracting chlamydia.
