We often assume drug prices rise solely due to corporate greed or inflation. In 2026, a different force is driving costs up. Structural changes in the supply chain are forcing price hikes. Manufacturers are exiting low-margin markets. Others are shifting products to “authorized generics” that lack insurance coverage.
These supplier decisions create artificial scarcity. That scarcity allows remaining players to raise prices. You might find your copay doubled because the “preferred” supplier stopped making your drug. Here are the seven prescription medications seeing price increases due to supplier changes this year.
1. The Asthma Inhaler Discontinuation
GlaxoSmithKline (GSK) discontinued the popular Flovent inhaler to shift to an authorized generic. This move was intended to lower costs potentially. However, many insurers have not added the new generic to their formularies yet. This leaves patients without a covered option. You may be forced to pay cash prices for the new generic. Alternatively, you might switch to a more expensive brand-name competitor. The gap in supplier contracts has effectively raised the monthly cost for thousands of asthma patients.
2. ADHD Stimulant Manufacturing Quotas
The shortage of Adderall and Vyvanse has morphed into a pricing crisis. DEA production quotas remain strict despite rising demand. Major suppliers like Teva face manufacturing backlogs. This scarcity has forced patients to buy expensive brand-name versions. Generics are often out of stock or marked up by wholesalers. Patients without coverage are seeing prices double or triple at the pharmacy counter.
3. Amoxicillin Market Prioritization
Basic antibiotics are becoming more expensive due to global market shifts. Manufacturers like Sandoz are prioritizing countries with higher reimbursement rates. This leaves the U.S. market vulnerable to spot shortages. Import prices for Amoxicillin have trended higher as logistics costs rise. You might see a higher cash price at independent pharmacies. The supply chain is fragile, and any disruption now spikes the consumer cost immediately.
4. The Covid Vaccine Commercial Shift
The federal government is no longer purchasing Covid-19 vaccines in bulk. Manufacturers like Pfizer have moved to commercial pricing models. The price per dose has risen significantly compared to the subsidized era. Insurers absorb some of this, but premiums are rising to match. Uninsured patients now face a bill of over $100 per shot. This is a direct result of the supplier shifting from a government contract to the private market.
5. Hospital Pain Medication Hikes
Pfizer and other sterile injectable manufacturers have raised prices on hospital-grade painkillers. Drugs like morphine and hydromorphone are seeing steep increases. Manufacturers cite rising “manufacturing and distribution expenses.” These costs are passed on to patients during surgery or ER visits. You will not see this at the pharmacy counter. You will see it on your hospital bill under “Pharmacy Services.”
6. Chemotherapy Generic Exits
Low profit margins are driving manufacturers out of the generic cancer drug market. Essential drugs like Cisplatin are frequently in shortage. When major suppliers exit, the remaining supply becomes expensive. Hospitals turn to “gray market” suppliers to secure doses. These costs are often passed to patients or result in higher insurance premiums. The lack of reliable suppliers is keeping prices artificially high for life-saving treatments.
7. GLP-1 Supply Chain Squeeze
Weight loss drugs like Wegovy remain in short supply. Manufacturers cannot build production capacity fast enough to meet demand. This scarcity allows suppliers to maintain high list prices. They have little incentive to offer deep rebates to insurers. Consequently, many plans are dropping coverage or raising copays. The supplier’s inability to scale production is directly keeping your out-of-pocket costs high.
Check Authorized Generics
You cannot control supplier exits. You can check if an “authorized generic” is covered. Ask your pharmacist if a manufacturer change caused your price hike. If so, call your insurer to request a “formulary exception.” In 2026, you must track who makes your medicine to understand why it costs so much.
