A 29-year-old lady presented with an increasingly swollen tongue 3 days after commencing oseltamivir (Tamiflu) for flu-like symptoms. Once identified as the cause, her symptoms rapidly improved with antihistamines and discontinuing the Tamiflu. The authors find only one other case in the literature reporting this very rare side effect.
