Annual Notice of Change (ANOC):

The Medicare Annual Notice of Change (ANOC) is a letter for people enrolled in Medicare Advantage plans and anyone with Medicare Part D prescription coverage. People with Medicare Advantage or original Medicare (Part A and/or Part B) can have Part D plans. The ANOC informs enrollees about any changes to their benefits for the coming coverage year. By law, Medicare Advantage and Part D plans must send the ANOC to enrollees by September 30 — which is before the annual Medicare open enrollment period of October 15 to December 7. Even if you have the same plan, your benefits could change year to year.

Premium:

A premium is the cost of having a health insurance plan and is usually paid monthly. Medicare enrollees may pay several premiums. Most people don’t pay anything for Part A hospital insurance, but some people do depending on how long they worked and paid taxes. For outpatient and preventive coverage, the Part B standard premium is $185 a month in 2025, but people with higher incomes pay more. Your premium for Medicare Advantage plans will vary, but even so-called “zero premium” plans require you to pay your Part B premium. Part D premiums range in price, but the average is about $47 a month in 2025. If you have original Medicare and a Medigap supplement plan, you have an additional premium for that coverage.

Deductible:

A deductible is the amount you pay out of pocket before your Medicare plan begins cost-sharing. In 2025, the Part A deductible is $1,676 per benefit period. The Part B deductible is $257 for the year, but you can access certain preventive care — including some vaccines — without meeting your deductible. Medicare Advantage deductibles vary and your Part D deductible can’t exceed $590 in 2025.

Out-of-pocket limit:

Original Medicare has no annual out-of-pocket maximum. Medicare Advantage plans have out-of-pocket limits. In 2025, they are $9,350 for in-network covered services and $14,000 for in-network and out-of-network covered services combined.

Medicare Prescription Payment Plan:

Starting January 1, 2025, anyone with Part D coverage had the option to use the Medicare Prescription Payment Plan for their out-of-pocket medication costs instead of paying upfront at the pharmacy. This plan doesn’t provide savings, but allows you to spread prescription costs — including your deductible — over the year. Making payments can be particularly helpful for people who may skip or delay picking up prescriptions because of high costs early in the year. Also in 2025, the Part D out-of-pocket limit dropped to $2,000.

Initial coverage phase:

After a Medicare enrollee meets the Part D deductible (if the plan has one), the health insurance begins cost sharing. The initial coverage phase means you pay coinsurance or a copay for covered prescriptions.

Catastrophic phase:

When you reach the $2,000 out-of-pocket maximum, your Part D plan pays for 100% of covered medications for the rest of the year.

How to save on drugs with Medicare

Medicare Part D is the part of Medicare that helps cover prescription medications, including both brand name and generic. It also includes coverage for certain vaccines that aren’t covered by Part B, as well as some medical supplies.

Even with Medicare Part D coverage, you may still have out-of-pocket costs such as premiums, deductibles, copayments, and coinsurance. As of 2025, Medicare Part D plans include a $2,000 annual out-of-pocket cap. Once you reach this limit, your plan covers the full cost of your covered medications for the rest of the year.

Still, there are several ways to reduce your prescription medication cost. From GoodRx coupons to patient assistance programs, here are ways you can save money on the medications you need.

1. See if you qualify for Medicare’s Extra Help program

The Medicare Extra Help/Low-Income Subsidy program is a federally funded program for people covered under a Medicare Part D plan. It helps reduce enrollees’ out-of-pocket costs by limiting their deductibles and copays. To qualify, your income and assets fall below a certain limit.

If you’re eligible, you may receive:

  • No monthly premiums for Medicare Part D

  • No Medicare Part D deductible

  • Low copays for prescription medications

2. Use GoodRx coupons

You can’t combine GoodRx coupons with Medicare, but you can choose to use a coupon instead of your insurance if it results in a lower price.

Here’s how to download a GoodRx coupon:

  1. Go to the GoodRx website, or download the GoodRx app on your phone.

  2. Search for your prescription medication.

  3. Enter your prescribed dose and quantity, then set your location.

  4. Compare prices across different pharmacies in your area.

  5. Click “Find the lowest prices” or press “Enter.”

  6. You can have the coupon sent by text or email, or print it out.

  7. To apply the discount, show the coupon at the pharmacy when you fill your prescription. Ideally, this is done at drop-off before the prescription is filled.

3. Consider the Medicare Prescription Payment Plan

The Medicare Prescription Payment Plan is a new program that can help make paying for medications more manageable. It’s open to anyone with a standalone Part D plan or those with Medicare Advantage plans that offer prescription medication coverage.

There is no cost to participate in the Medicare Prescription Payment Plan and participation is voluntary. Instead of paying for the total cost of your medications up front at the pharmacy, the payment plan allows you to spread the cost into smaller payments during the year. If you join, you will continue to pay your premium every month as well as an additional monthly amount on your payment plan. It’s a good idea to review how the Medicare Prescription Payment Plan works to determine if it’s right for you.

4. Compare Part D plans during open enrollment

Medicare open enrollment, which takes place every year from October 15 to December 7, is your chance to switch plans if another option offers better prescription medication coverage or lower costs. Plan costs and coverage details can change each year, so it’s important to review your options.

Here are some steps to help you compare plans:

  1. Make a list of all your medications and what dosages you take.

  2. Enter the names of your prescription medications to see which plans offer the best coverage.

  3. Look at premiums, deductibles, and medication costs for each plan. Plans usually change their formularies, premiums, and copays annually.

  4. Check if your preferred pharmacy is in each plan's network.

5. Get a 90-day supply

Opting for a 90-day supply instead of a monthly refill of your medication might help reduce your long-term out-of-pocket costs. Many insurance plans offer lower copays or bulk pricing for 3-month prescriptions.

If your medication is covered under your plan, see if your insurer’s mail-order or specialty pharmacy provides savings on a 90-day supply. If they do, ask your prescriber to write a prescription for a 90-day quantity to take advantage of these potential savings.

6. Ask about the generic version of your medication

Some medications have a generic version, and they generally cost less than the brand-name prescriptions. Generic medications are just as safe and effective as brand-name medications, so it’s an option worth considering to reduce your cost. Ask your prescriber about switching to a generic version of your medication to save money.

7. Consider lower-cost alternative medications

There may be other medications that help manage your condition, and they may cost less. If your medication is costly or not covered by your insurance, talk to your prescriber about lower-cost alternatives that might be a good option for you. Alternatives might have better insurance coverage or lower costs.

8. Learn more about patient assistance programs

Patient assistance programs (PAPs) offer free or low-cost medications to uninsured and low-income consumers. These programs, which primarily offer savings on brand-name medications, are usually run by private pharmaceutical companies or nonprofit organizations. You must meet certain qualifications and complete paperwork to receive savings from PAPs. However, some PAPs exclude Medicare recipients, so it’s important to review the program’s rules and requirements carefully.

9. Check state-funded resources

Depending on where you live, your state may offer programs to help you navigate prescription medication costs. A good place to start is your local Department of Aging. This U.S. Department of Health and Human Services office can help you find the best Medicare plan for the coverage you need.

Some states even have their own cost-saving programs for older adults. For example, Pennsylvania runs PACE and PACENET. These programs help eligible residents get prescription medications at reduced costs.

Alternatively, you can find out if your state has a State Pharmaceutical Assistance Program by using Medicare’s search tool. These programs are state-run and help qualifying residents pay for prescription medications.

10. Use a health savings account to pay for prescription medications

Although you can’t contribute to a health savings account (HSA) after enrolling in Medicare, you can still use any remaining funds in your account to pay for qualified medical expenses. An HSA allows you to use tax-free dollars to pay for eligible prescription medications. The money in your account does not expire so you can use your funds at any time to reduce your out-of-pocket medication costs.

Frequently asked questions about Voltaren

Before you start Voltaren, ask your provider for guidance on how long you should take this medication. The length of treatment can differ from person to person, depending on what medical condition you have and what formulation of diclofenac you're taking. For example, if you're taking diclofenac (Cambia) for migraine attacks, you should only take one dose. But if you're taking diclofenac tablets for arthritis, your provider will likely ask you to take it regularly for at least 1 to 2 weeks to see if you experience relief from pain and inflammation. In general, you should take the lowest dose of Voltaren for the shortest amount of time needed to treat your symptoms. This is because taking Voltaren for too long and at higher doses can raise your risk for serious side effects, such as heart attack or stroke.

It'll take about 5 to 10 hours for your body to clear most of Voltaren after a single dose. This timeframe is estimated based on the half-life of Voltaren, but it can differ depending on other factors such as what other medications you're taking and your medical conditions. It can also be influenced by what formulation of Voltaren you're taking. Talk with your provider if you've more questions about how long this medication stays in your system.

Yes, you can take acetaminophen (Tylenol) with Voltaren together because they work differently in your body to relieve pain. Before you start taking acetaminophen (Tylenol), ask your provider if it's appropriate for you. While acetaminophen (Tylenol) is generally safe to take, it does carry certain risks, such as the risk of liver problems for people who already have liver damage or who drink alcohol regularly.

Sleepiness isn't a common side effect reported by people who take Voltaren. But rarely, some people have felt dizzy or drowsy after taking this medication. If you feel sleepy after taking Voltaren, let your provider know. They can check to see if the sleepiness is a side effect of Voltaren or whether its caused by another medication or medical condition.

No, Voltaren isn't muscle-relaxer; it's a NSAID. But certain forms of Voltaren is FDA-approved to ease mild to moderate pain, which can include pain in muscles. If you have muscle pain or tension, talk with your provider about what treatment options are best for you.

Don't take Voltaren with other NSAIDs, such as ibuprofen (Advil), naproxen (Aleve), or even topical NSAIDs like diclofenac (Voltaren) gel. Doing so puts you at higher risk for severe side effects (e.g., stomach bleeds, stroke, heart attack). NSAIDs are commonly found in over-the-counter pain and cold medications. Talk with your healthcare provider or pharmacist if you're not sure whether you're already taking an NSAID.

If you're prescribed Voltaren and become pregnant while taking the medication, stop using it and let your provider know right away. A study from the CDC showed that babies born to mothers who took NSAIDs in early pregnancy had a higher risk of birth defects (e.g., hole in the stomach, cleft palate), compared to mothers who took acetaminophen (Tylenol). Additionally, the FDA specifically says to avoid NSAIDs in pregnant females who are at least 20 weeks pregnant because it can cause kidney and heart problems to your unborn baby. Don't use Voltaren if you're pregnant until your provider specifically said it was safe for you to do so.

Diclofenac sodium and diclofenac potassium are different salt forms of Voltaren. The salts affect how fast the medication gets absorbed into your body. Diclofenac potassium is absorbed by your body more quickly compared with diclofenac sodium. That's why it can treat sudden, sharp pain from certain conditions, such as migraines or menstrual cramps. On the other hand, diclofenac sodium is typically used for other conditions that cause pain that last longer (e.g., arthritis etc.) since it works more slowly and stays in your body longer.
