Thanks for your question and concern. The most effective way to treat the infection that you are facing is by identifying the organism that has caused you infection and then take the medication on the basis of the organism that is present. Now when you cannot visit the doctor as you have mentioned because it is not possible for you to do so, it is really difficult to predict the type of organism present in the infection without testing. As you mentioned, you are currently consuming the medication named Doxycycline of 100 mg that prevents malaria so, I would suggest you to continue taking that medication for the next weeks two times a day so that the STDs such as chlamydia or gonorrhea gets treated effectively. Also I would suggest you to get the checkup done again whenever you can visit the doctor to make sure that you are no more suffering from any of the STDs to avoid any kind of inconvenience in future. In case no attention is paid to such a problem, it can lead to some serious issue in future.You may also call the free helpline and discuss your issue in detail with the nurse available at the helpline. It is always made sure that your problems and issues are not discussed with anyone until you want so. You can also ask them to provide you a complete knowledge about the different infections and diseases caused due to the unprotected sex and how can you protect yourself from all those infections and diseases. I hope that you get well soon. Best wishes.
