Does Nerlynx cause hair loss?

Official answer


Hair loss has not been reported as a side effect of Nerlynx. Hair loss is also not an anticipated side effect of Nerlynx because of the targeted way that it works, so if hair loss were to occur, it is probably due to other causes.

The most common side effect of Nerlynx (neratinib) is diarrhea. Other side effects that may be reported include:

  • Dizziness
  • Dry mouth
  • Fainting
  • Increased heart rate
  • Lightheadedness
  • Rapid breathing
  • Sunken eyes
  • Thirst
  • Unusual tiredness or weakness
  • Wrinkled skin.

Some of these side effects may be caused by dehydration due to diarrhea.
