I'll probably get flamed for this, but that's ok. You'll go to Hell if you reject Christ and His payment for everyone's immorality regardless of what you did in this life.
I don't intend to flame you, but I will tell you that you need to get your priorities straight BEFORE you enter pharmacy school and I give you advice since I'm a practicing pharmacist.
We do indeed, as do all health professionals, have a conscious clause - but it is not on a case by case basis. For us, it is on a drug cased basis & you must decide AHEAD of time how you believe & if you believe in dipensing the drug under ANY circumstance, you will dispense the drug under EVERY circumstance. That means you must absoutely keep up on every drug with all its off label uses, in case you come across one you object to.
That means, if you will dispense misoprostol for GI effects secondary to NSAIDS, you'll also dispense it for cervical dilatation prior to an elective termination of pregnancy. Likewise, if you'll dispense Levora to a 30 yo married woman,you'll also dispense it to a 12 yo unmarried girl. There is no room for morality once you've signed AHEAD of time your own personal restrictions, which must be drug based.
Likewise...your obligation extends to giving the rx back to the pt & doing your best to find the medication &/or a pharmacist in the neighboring area which will fill it (& documenting you did so).
This is clear & uniform in all states, particularly after the Plan B debacle. You will be given a document to sign stating you have specific drugs you won't dispense or not. The company/corporation/hospital you work for will accept that & will assign you based on that staement.
I know of pharmacists who choose not to dispense certain drugs & have indeed written a disclaimer which allows them not to do so. However, this also limits their job opportunities. You will rarely be allowed to work alone.
You just must be aware of how your moral beliefs will limit your job opportunitites once you become licensed.
Once you become licensed, your morals will take a back seat unless you state up front and AHEAD OF TIME (this is the crucial part) that you will or won't dispense a drug. Otherwise, as a previous poster mentioned, it hinders appropriate tx & becomes a hurdle the patient & prescriber unnecssarily have to get over.
