Dear Doc,

Since I was given the Lamivudine/Zidovudine/Nevirapine combo, I noticed that my fingernails have been darkening. I am not alone in this, with other PLHIVs also taking the same combo experiencing this problem. Should we worry? What do we do?

Dark Matters

Thank you for your question. Regarding your concern on the – using your words – “darkening” of fingernails, this is best assessed by a medical doctor during consultation. But such sign, and looking into the drug history of intake of Lamivudine/Zidovudine (AZT), I presume that this may be attributable to the drug’s anemia side effect.

Anemia is one of the most common side effects for those taking the Lamivudine/Zidovudine combination. Normal fingernail beds are usually “pink” in color, and this signifies good oxygenation reaching the lesser vital organs of the body. Why is this so? Because human body is compensating to flow blood to more important organs (e.g. brain, heart, lungs, kidneys) that are more important for survival.

Once fingernail beds turn darker (i.e. bluish/violaceous) in color, this means there is poor oxygenation in the less vital organs of the body. Furthermore, the fingernails could further be disfigured, even looking like “clubbed fingers”.

To wrap up, during your medical visits, your attending medical doctors should keenly observe this, and he/she may ask further questions to ascertain is this is related to anemia.

Should one be worried? Yes, if one is not being seen or supervised by a medical doctor; and if one is not having regular health check ups.  But know that anemia is treatable.
