Pharmacy School Prerequisites: The Complete Guide- Pharmacy school carries one of the heaviest prerequisite loads in all of pre-health. To enter a Doctor of Pharmacy (PharmD) program, you typically need a full sequence of chemistry — general chemistry, two semesters of organic chemistry, and biochemistry — plus biology, anatomy and physiology, microbiology, calculus, statistics, physics, and a set of general-education courses. Getting these pharmacy school prerequisites right, in the right order and within each program’s recency window, is the foundation of a competitive application. This complete guide walks through every required course, how the chemistry chain works, GPA and recency expectations, and how to complete your prerequisites online as regionally accredited, transferable credit.
Prerequisites are the undergraduate courses a PharmD program requires you to complete before you matriculate — the academic foundation the professional curriculum is built on. Pharmacy programs are accredited by the Accreditation Council for Pharmacy Education (ACPE), and most use the centralized PharmCAS application. While exact requirements vary by program, the core list is remarkably consistent, and it’s heavily weighted toward chemistry — which is why pharmacy is one of the most prerequisite-intensive paths a student can choose. Requirements also vary in how recent the coursework must be, a point we’ll return to below.
Here is the typical PharmD prerequisite set. Always confirm the exact list against each program and PharmCAS, but this covers what nearly every school expects:
| Requirement | Typical scope | Maps to |
|---|---|---|
| General Chemistry I & II (w/ lab) | Two semesters — the gate before organic | CHEM 152 |
| Organic Chemistry I & II (w/ lab) | Two semesters — the defining pharmacy prerequisite | CHEM 251, CHEM 252 |
| Biochemistry | Required by nearly every PharmD program | CHEM 330, CHEM 331 |
| Anatomy & Physiology I & II | Two semesters, commonly required | BIO 270, BIO 275 |
| Microbiology | One semester with lab | BIO 210 |
| Calculus | One semester | MATH 120 |
| Statistics | One semester | MATH 220 |
| Physics | Often one semester | PHY 116 |
| Economics | Sometimes required (micro or macro) | See pharmacy courses |
| English, public speaking, humanities/social sciences | General-education requirements | Confirm with program |
You take what your target programs require — not every school asks for all of these — but the chemistry sequence is close to universal. Begin exploring the live courses on the pharmacy prerequisites page.
No subject defines pharmacy prerequisites like chemistry. The sequence builds on itself: general chemistry establishes the fundamentals, organic chemistry I and II develop the reaction chemistry that pharmacology depends on, and biochemistry connects it to biological systems. Because each course is a prerequisite for the next, the chemistry chain has to be planned as a sequence, not a checklist of independent items.
If you need several of these, the pharmacy chemistry sequence bundle sequences them on one timeline. And if organic chemistry is the course that worries you, you’re not alone — see how hard is organic chemistry for pharmacy school?
Beyond chemistry, PharmD programs expect a biological and quantitative foundation. Anatomy and physiology and microbiology supply the human-systems knowledge the curriculum assumes, while calculus and statistics provide the quantitative reasoning used throughout. Physics rounds out the science load at many programs. These can often run in parallel with the chemistry chain since they don’t depend on it. See A&P and microbiology for pharmacy online and physics and calculus for pharmacy prerequisites.
Pharmacy admissions weigh your overall GPA and, especially, your science GPA — the grades in exactly these prerequisite courses. This has become more important because the PCAT was retired in January 2024, so most programs no longer require an admissions test. With that standardized metric gone, prerequisite grades carry even more weight as evidence of academic readiness. That makes strong grades in the chemistry chain doubly valuable. For the details, see what GPA you need for pharmacy school and is the PCAT still required?
A detail that catches career changers and gap-year applicants off guard: many pharmacy programs expire science prerequisites after roughly five to seven years. Coursework older than that window may need to be retaken even if you passed it the first time, because programs want recent evidence you’ve retained the foundation. This is one of the most common reasons applicants find themselves repurchasing organic chemistry or biochemistry years after college. Confirm each program’s recency policy and PharmCAS’s requirements, and see pharmacy prerequisite recency rules.
You don’t have to return to a campus to complete pharmacy prerequisites. Self-paced, regionally accredited online courses let you finish the required coursework on your own schedule, as institutional credit that posts to an official transcript. The key is accreditation: credit needs to come from a regionally accredited institution to transfer cleanly and be recognized by PharmCAS programs. PrereqCourses delivers the full pharmacy prerequisite set — the chemistry chain, biology, math, and physics — online through Upper Iowa University, regionally accredited by the Higher Learning Commission, at $695 per course. For the accreditation details, see can you take pharmacy prerequisites online? and online pharmacy prerequisites that transfer to PharmCAS.
Confirm everything with your programs and PharmCAS. Prerequisite lists, recency windows, and accepted courses vary by program and change over time, and acceptance of any outside course is never automatic. Confirm requirements with each program’s admissions office, the registrar, and PharmCAS before enrolling. This guide covers admissions and prerequisites only — not clinical or pharmacological topics — and we don’t guarantee admission or transfer.
Typically general chemistry, organic chemistry I and II, biochemistry, anatomy and physiology, microbiology, calculus, statistics, physics, and general-education courses such as English. The chemistry sequence is close to universal. Confirm the exact list with each program.
Yes — a full two-semester organic chemistry sequence with lab is one of the most universal pharmacy prerequisites, because pharmacology builds directly on it. Biochemistry is also required by nearly every program.
No. The PCAT was retired in January 2024, and pharmacy schools no longer require it. As a result, prerequisite grades and GPA carry even more weight in admissions.
Many programs expire science prerequisites after roughly five to seven years, so older coursework may need to be retaken. Confirm each program’s recency policy and PharmCAS requirements.
Yes — self-paced, regionally accredited online courses that post to an official transcript can satisfy pharmacy prerequisites, including lab sciences. Confirm acceptance with your programs and PharmCAS before enrolling.
It varies by program, but both overall and science GPA matter, and science GPA — your grades in these prerequisites — is weighed heavily, especially now that the PCAT is gone. See the dedicated GPA guide.
