Cancer Treatment

How it works

Inhibits poly(ADP-ribose) polymerase (PARP) enzymes, preventing DNA repair in BRCA-mutant cancer cells and leading to accumulation of DNA damage and cell death. This synthetic lethality approach is particularly effective in tumours with BRCA1 or BRCA2 mutations that rely on PARP-mediated homologous recombination repair pathways.

How to take this drug

Take one 1 mg capsule by mouth once daily, with or without food. Swallow the capsule whole — do not open, chew, or dissolve it. Take it at roughly the same time each day. Your doctor will decide how long you need to stay on it and may adjust your dose based on how your body responds.

What if I Miss a Dose?

If you miss a dose or vomit after taking it, do not take an extra dose. Just take your next dose at the usual scheduled time the following day.

What to watch out for

This is a highly specialized cancer drug — only take it if prescribed and supervised by an oncologist (cancer specialist). Do not buy from unverified sources or roadside sellers, as counterfeit cancer medicines are extremely dangerous. Regular blood tests are essential while on this medicine, so keep all your hospital appointments.

Common Side Effects

Feeling very tired or weak
low blood counts (which can cause easy bruising
bleeding
or frequent infections)
nausea and vomiting
hair thinning or hair loss
loss of appetite

Serious Side Effects

Severe drop in blood cells — watch for unusual bleeding
bruises that won't stop
very high fever
or extreme tiredness and breathlessness (this needs urgent hospital attention). In rare cases
it may increase the risk of developing a different type of blood cancer called MDS or AML.

Drug Interactions

Certain antibiotics and antifungals (like ketoconazole or itraconazole) can increase talazoparib levels dangerously in your body — always tell your doctor about any other medicine you are taking. Acid-reducing stomach drugs like omeprazole may also interact. Avoid alcohol as it can worsen side effects like tiredness and nausea.
