The U.S. Food and Drug Administration on Wednesday approved selling naloxone without a prescription, setting the overdose-reversing drug on course to become the first opioid treatment drug to be sold over the counter by late summer. Other brands of naloxone and injectable forms will not yet be available over the counter, but they could be soon.

Narcan can reverse overdoses of opioids, including street drugs such as heroin and fentanyl and prescription versions including oxycodone.

The Senate is poised to vote Wednesday to repeal the 2002 measure that greenlighted the March 2003 invasion of Iraq, which would end more than 20 years of authorization for U.S. presidents to use force in that country and return those war powers to Congress.

About 2,500 U.S. troops remain in Iraq at the invitation of the Iraqi government.

Russia will no longer give the U.S. advance notice about its missile tests, a senior Moscow diplomat said Wednesday, as its military deployed mobile launchers in Siberia in a show of the country’s massive nuclear capability amid fighting in Ukraine.

The termination of missile test warnings marks yet another attempt by Moscow to discourage the West from ramping up its support for Ukraine by pointing to Russia’s massive nuclear arsenal.
