Prolixin is a antipsychotic drug. Dr. is prescribing the drug in liquid form so we will need to figure out how many ml's is 6mg from the sig provided. 4mg = 5ml
{So 7.5ml equals 6mg of the drug} Per dose: 7.5ml
Entire treatment: 22.5ml x 90 days= 2025ml (that is alot of liqiuid medication) Crystal Zamudio, CPhT

What is weight of Calcium Carbonate for the new insuffulation and what is the weight of Amoxicillin for the new insuffulation? One way is , Let the aamount of amoxicillin be x, then Calcium carbonate is 3x therefore x + 3x = 300 mg 4x = 300 mg
Let me know if this answer is correct. If not i will try with another method.
