Lisinopril and rare side effects

Been on this med 10mg for 1.5 years . No issues. Over the weekend a friend had to be admitted due to angiodema. It’s rare but she’s been on it 5 years . 43 years old . Anyone have any serious issues like this ? Just got me a little scared . It’s rare but still . I know cough big deal but never heard of it until now Any info would be helpful
