Questions about Ofev’s dosing

Below are some common questions about Ofev’s dosing.

  • What if I miss a dose of Ofev? If you miss a dose of Ofev, skip the missed dose and take your next dose at its regular time. You should not take more than one dose of Ofev at a time. This could raise your risk of side effects.
  • Will I need to use Ofev long term? Yes. If you and your doctor agree that Ofev is working well for you, you’ll likely take the drug long term.

How does Ofev compare with similar drugs, such as pirfenidone (Esbriet)?

Ofev and pirfenidone (Esbriet) are both used to treat idiopathic pulmonary fibrosis (scarring in the lungs with no known cause) in adults.

Both Ofev and Esbriet come as a capsule that you swallow, and both are taken with food. (Esbriet is also available as a tablet that you swallow and take with food).

The drugs have some similar side effects, such as nausea, diarrhea, and liver-related side effects.

But these drugs also have some differences. For example, Esbriet may cause your skin to be more sensitive to light, including sunlight. It may not be the best treatment choice if you spend a lot of time in the sun.

On the other hand, Ofev can cause blood clots in rare cases. It may not be the best treatment choice if you have heart disease or other heart problems that raise your risk of blood clots.

To learn more about how Ofev and Esbriet compare, talk with your doctor or pharmacist.

What is Ofev’s cost with Medicare?

Ofev’s cost with Medicare will vary, depending on a few factors. These include:

  • the specifics of your Medicare plan and whether it includes prescription drug coverage
  • the pharmacy you use

To learn more about Ofev’s cost with Medicare, contact your insurance provider. You can also talk with your pharmacist to get a cost estimate for your Ofev prescription.

How does Ofev work?

Ofev is used to treat certain conditions that cause scarring and inflammation in the lungs.

Ofev works by slowing the buildup of scar tissue in your lungs. It does so by blocking certain enzymes (proteins) in your body that help form scar tissue.

To learn more about the conditions Ofev treats and how it works, see the “What is Ofev used for?” section below. You can also talk with your doctor or pharmacist to learn more about how Ofev works.

Does Ofev cause eye-related side effects?

No, Ofev should not cause eye-related side effects. These weren’t reported by people taking Ofev in studies.

Sometimes, drugs called corticosteroids are used to treat interstitial lung disease. (Ofev also treats interstitial lung disease in certain cases.) And corticosteroids may cause eye-related side effects. But Ofev is not a corticosteroid and isn’t known to affect the eyes.

Check out this article to learn more about corticosteroids and possible effects on vision. But this side effect isn’t expected with Ofev.

Ofev is used to treat certain kinds of lung disease in adults. See below for details.

Idiopathic pulmonary fibrosis. With idiopathic pulmonary fibrosis, you have scarring in the lungs with no known cause. Symptoms can include:

  • shortness of breath
  • dry cough that doesn’t go away
  • discomfort in your chest
  • fatigue (low energy)
  • weakness

Chronic interstitial lung disease with worsening fibrosis (scarring). Interstitial lung disease is a group of conditions that affects the air sacs in your lungs. Over time, scarring gets worse and decreases how well your lungs work. Symptoms of this condition may include:

  • dry cough
  • shortness of breath, especially with exercise or climbing stairs
  • discomfort or pain in your chest
  • fatigue

Interstitial lung disease associated with systemic sclerosis. Systemic sclerosis is a condition that leads to tissues in your body becoming thickened and scarred. Symptoms of interstitial lung disease are described above.

Each condition described above involves scarring in your lungs. Ofev works by slowing the buildup of scar tissue in your lungs. It does so by blocking certain enzymes (proteins) in your body that are needed for scar tissue to form. Over time, preventing new scar tissue from forming helps reduce how fast your condition and symptoms worsen.

Before you begin taking Ofev, there are important considerations to discuss with your doctor. This includes telling your doctor about any medications you may take and your complete health history. This allows your doctor to check for interactions with Ofev.

Interactions

Taking a medication with certain vaccines, foods, and other things can affect how the medication works. These effects are called interactions.

Before taking Ofev, be sure to tell your doctor about all medications you take, including prescription and over-the-counter types. Also describe any vitamins, herbs, or supplements you use. Your doctor or pharmacist can tell you about any interactions these items may cause with Ofev.

For information about drug-condition interactions, see the “Warnings”section below.

Interactions with drugs or supplements

Ofev can interact with several kinds of drugs. Examples include:

  • drugs that affect a certain enzyme (protein), such as the:
    • seizure medications carbamazepine (Tegretol, others) and phenytoin (Dilantin)
    • heart drugs diltiazem (Cardizem LA, others) and verapamil (Calan SR, others)
    • antibiotic drug rifampin
    • antibiotics clarithromycin and erythromycin (Ery-Tab)
  • blood thinners, such as warfarin (Jantoven) or apixaban (Eliquis)

This list doesn’t contain all types of drugs that may interact with Ofev. Your doctor or pharmacist can tell you more about these interactions and any others that may occur while taking Ofev.

Warnings

Ofev can sometimes cause harmful effects in people who have certain conditions. This is known as a drug-condition interaction. Other factors may also affect whether Ofev is a good treatment option for you.

Talk with your doctor about your health history before you take Ofev. Factors to consider include those described below.

Bleeding problem. Ofev increases your risk of bleeding. If you already have a bleeding problem, your risk of bleeding may be higher while taking Ofev. Talk with your doctor to learn more about whether Ofev is safe for you.

Heart problems. Ofev can cause heart-related side effects, including hypertensive crisis and heart attack. If you already have a heart problem, such as heart disease, you may have a higher risk of these side effects while taking Ofev. The drug could also worsen your existing heart condition. If you have a heart condition, talk with your doctor about whether Ofev is safe for you.

Liver problems. Ofev may cause liver-related side effects, including liver damage in rare cases. Due to this risk, doctors typically won’t prescribe Ofev if you have a moderate or severe liver problem.

If you have a mild liver problem and your doctor decides to prescribe Ofev for you, they’ll likely prescribe a lower dose. If you have a liver problem, ask your doctor whether Ofev is right for you.

Severe kidney problem. Ofev hasn’t been studied in people with severe kidney problems, such as end-stage kidney disease. If you have a kidney problem, talk with your doctor about whether Ofev is safe for you to take.

Allergic reaction. If you’ve had an allergic reaction to Ofev or any of its ingredients, your doctor will likely not prescribe Ofev. Ask them what other medications are better options for you.

Ofev and alcohol

There’s no known interaction between Ofev and alcohol. But Ofev and alcohol can cause similar side effects, such as diarrhea, headache, and nausea. Combining alcohol and Ofev may raise your risk of these side effects or could make the side effects that you experience worse.

If you drink alcohol, talk with your doctor about how much, if any, is safe for you to drink while taking Ofev.

Pregnancy and breastfeeding

See below for details on whether Ofev can be taken during pregnancy or while breastfeeding.

Ofev and pregnancy

Ofev is not safe to take during pregnancy because it could cause harm to a fetus.

If you can become pregnant:

  • your doctor will have you take a pregnancy test before prescribing Ofev for you
  • your doctor will recommend that you use birth control while taking Ofev and for at least 3 months after your last dose

If you’re pregnant or planning to become pregnant, talk with your doctor about your treatment options.

Ofev and breastfeeding

Breastfeeding is not recommended while taking Ofev. It isn’t known if the drug passes into breast milk. But based on how the drug works, the drug could cause serious side effects in a breastfed child.

If you’re breastfeeding or planning to breastfeed, talk with your doctor about your treatment options.

Your doctor will explain how you should take Ofev. They’ll also explain how much to take and how often. Be sure to follow your doctor’s instructions.

Taking Ofev

Ofev comes as a capsule that you swallow.

Accessible medication containers and labels

If it’s hard for you to read the label on your prescription, tell your doctor or pharmacist. Certain pharmacies may provide medication labels that:

  • have large print
  • use braille
  • contain a code you can scan with a smartphone to change the text into audio

Your doctor or pharmacist may be able to recommend a pharmacy that offers these options if your current pharmacy doesn’t.

Also, if you’re having trouble opening your medication bottles, let your pharmacist know. They may be able to put Ofev in an easy-to-open container. Your pharmacist may also recommend tools to help make it easier to open the drug’s container.
