Generic: acetaminophen/phenylephrine/pheniramine
Generally yes, Theraflu is safe for adults when used as directed to relieve cold and flu symptoms like aches, fever, stuffy nose, and sneezing.

- Anyone currently taking a monoamine oxidase inhibitor (MAOI) or who has taken one within the last two weeks
- People with liver disease
- Pregnant or breastfeeding women
- Individuals with a chronic cough (e.g., from smoking, asthma, or emphysema) or a cough with excessive phlegm

Interactions to Watch For
Using Theraflu with other medications containing acetaminophen significantly increases the risk of severe liver damage.
Combining Theraflu with MAOIs can lead to a dangerous increase in blood pressure and other severe reactions due to the decongestant component.
Acetaminophen can increase the effect of warfarin, raising the risk of bleeding.
Consuming 3 or more alcoholic drinks daily while using Theraflu significantly increases the risk of severe liver damage.
