Does ART always work?
Nearly everyone can get an undetectable viral load on ART.
If you do not get a full response it can be for one (or more) of the reasons below.
- Drug interactions. Some medicines, including supplements and vitamins, can affect how you ARVs work. Speak to your doctor and pharmacist about all medicines and supplements you take.
- Side effects. You have to be able to tolerate your meds and they have to be easy for you to take.
- Missing doses. This means checking you are taking the right dose at the right time each day. It might mean you are not following food recommendations.
- Drug resistance. Your HIV may have been resistant to one or more of the drugs you used. UK guidelines recommend a resistance test before starting treatment to check for this.
- Choice of drugs. Is the combination strong enough. Some combinations are not recommended with a viral load over 100,000 copies/mL. Also, the higher you start, the longer it may take to come down.
Knowing a little about each issue is good before starting ART.
With all these factors covered, if you have a good doctor and you take your drugs carefully, everyone starting ART should be able to get an undetectable viral load.
