we need to amend or repeal the us Constitution the 2nd amendment is out dated even dangerous. It needs to be removed from the Constitution. I fear if we don’t, no public places will be safe (malls, schools, government buildings etc) the common man/woman has proven to careless to own a firearm in their residence. I you need a example just look at the recent gun shooting in schools or other public places they were nothing but massacres. I believe that this nation would be safer if only authorized people were allowed to carry firearms (law enforcement types). we need to stand as a nation for our safety and ask president trump to remove or change the 2nd amendment from the Constitution. It has no place in today civility and I hope others we agree. we can’t allow the gun fanatics to allow this unnecessary and since less murdering of innocent human being to continue. I talking about public shooting this gun thugs called NRA allowing to much gun violence and it can’t continue , etc please stand with me on this and put a end to it.
If your patient refuses or is unable to take oral medication, Invega Sustenna and Zyprexa Relprevv are potential alternatives (as is fluphenazine). Both Invega Sustenna and Zyprexa Relprevv begin acting right away, so no oral overlap is needed. Both medications are also conveniently packaged as pre-filled syringes; however, dosing can be a bit tricky. For example, Invega Sustenna requires two separate loading doses one week apart (234 mg on day one, and 156 mg on day eight). The maintenance dose, usually 117 mg (the equivalent of 6 mg oral), is given every four weeks (Bishara D, Neuropsychiatr Dis Treat 2010;6(1):561–572).
