Studies are few and far between, but the only reported interactions with wild lettuce are with sedative drugs as wild lettuce is purported to have sedative effects.
This would include drugs like antihistamines, opioids, and benzodiazepines. These are detailed on our individual drug interaction pages.

It is a tall, annual plant with small, yellow flowers and leaves that resemble the leaves of cultivated lettuce. Wild lettuce is sometimes called "opium lettuce" due to the milky sap it contains that has been purported to have sedative and analgesic effects.

Oseltamivir Phosphate Overview
-
Oseltamivir is used to treat some types of influenza infection ('flu') in adults, children, and infants (older than 2 weeks of age) who have had symptoms of the flu for no longer than 2 days. This medication is also used to prevent some types of flu in adults and children (older than 1 year of age) when they have spent time with someone who has the flu or when there is a flu outbreak. Oseltamivir is in a class of medications called neuraminidase inhibitors. It works by stopping the spread of the flu virus in the body. Oseltamivir helps shorten the time that flu symptoms such as a stuffy or runny nose, sore throat, cough, muscle or joint aches, tiredness, headache, fever, and chills last. Oseltamivir will not prevent bacterial infections, which may occur as a complication of the flu.
