The most effective medication used to prevent the onset of PCP is Bactrim. Bactrim is an antibiotic sulfa drug. Many women experience an initial allergic reaction when they first start taking Bactrim. Your doctor can start you out on a very low dose to get your body used to the drug. By taking just a little more each day, your body can adjust to taking a normal dose without having an allergic reaction.
Different people require different dosages.
Others may prescribe a daily dose. Remember, it is much easier to stay well than to try to get healthy after you are already sick. You can live longer by taking preventative treatments when they are prescribed to you. Waiting until you have an opportunistic infection involves a lot more pills, time in the hospital, home care and treatments. If your T-cells have ever been lower than 200, you should consider taking Bactrim or Dapsone.
