What is Elyxyb?

Elyxyb is a ready-to-use oral solution containing celecoxib that is used to treat migraine headaches in adults.

Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat conditions that cause pain and inflammation. Since 1998 celecoxib has been available in capsule form (Celebrex), but in 2020 the US Food and Drug Administration (FDA) approved Elyxyb oral solution.

Elyxyb oral solution is made using a self-micro emulsifying drug delivery system that enables celecoxib to be absorbed better and work faster. Elyxyb works within one hour to provide relief from a migraine attack.

Elyxyb is thought to work by inhibiting an enzyme called cyclooxygenase-2 (COX-2), which inhibits the production of a group of lipids called prostagladins. Prostagladins can cause inflammation and pain.

What is Elyxyb used for?

Elyxyb is a prescription medicine used for the acute treatment of migraine attacks with or without aura in adults.

  • Elyxyb is not used as a preventive treatment of migraine.
  • It is not known if Elyxyb is safe and effective in children.

Important information

Elyxyb contains the NSAID celecoxib. NSAIDs, including Elyxyb, can cause serious side effects, including:

  • Increased risk of a heart attack or stroke that can lead to death. This risk may happen early in treatment and may increase:
    • with increasing doses of NSAIDs
    • with longer use of NSAIDs

Do not take Elyxyb right before or after a heart surgery called a coronary artery bypass graft (CABG).

Avoid taking NSAIDs, including Elyxyb, after a recent heart attack, unless your healthcare provider tells you to. You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack.

  • Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus (tube leading from the mouth to the stomach), stomach and intestines:
    • anytime during use
    • without warning symptoms
    • that may cause death

The risk of getting an ulcer or bleeding increases with:

  • past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs
  • taking medicines called corticosteroids, antiplatelet drugs, anticoagulants, selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs)
  • increasing doses of NSAIDs
  • longer use of NSAIDs
  • smoking
  • drinking alcohol
  • older age
  • poor health
  • advanced liver disease
  • bleeding problems

Elyxyb should only be used:

  • exactly as prescribed
  • for the shortest time needed

Who should not take Elyxyb?

Do not take Elyxyb:

  • if you are allergic to celecoxib or any of the ingredients in Elyxyb. See below for a complete list of ingredients in Elyxyb.
  • If you are allergic to sulfonamides.
  • if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAIDs.
  • right before or after heart bypass surgery.

What should I tell my doctor before taking Elyxyb?

Before taking Elyxyb, tell your healthcare provider about all of your medical conditions, including if you:

  • have liver or kidney problems.
  • have a history of stomach ulcer or bleeding in your stomach or intestines.

Other information about NSAIDs

Aspirin is an NSAID but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines.

Some NSAIDs are sold in lower doses without a prescription (over-the counter). Talk to your healthcare provider before using over­ the-counter NSAIDs for more than 10 days.


Tell your healthcare provider about all of the medicines you take, including prescription or over-the-counter medicines, vitamins or herbal supplements. NSAIDs, including Elyxyb, and some other medicines can interact with each other and cause serious side effects. Do not start taking any new medicine without talking to your healthcare provider first.

Especially tell your doctor if you take:

  • Corticosteroids
  • Antiplatelet and anticoagulant drugs such as warfarin and aspirin
  • SSRIs
  • SNRIs
  • Ace inhibitors, angiotensin receptor blockers or beta blockers
  • Diurectics
  • Digoxin
  • Other NSAIDs

If you are not sure if you take one of these medications then check with your doctor or pharmacist.

Pregnancy and breastfeeding

Tell your doctor if you are pregnant or plan to become pregnant. Taking NSAIDs, including Elyxyb, at about 20 weeks of pregnancy or later may harm your unborn baby. If you need to take NSAIDs for more than 2 days when you are between 20 and 30 weeks of pregnancy, your healthcare provider may need to monitor the amount of fluid in your womb around your baby. You should not take NSAIDs after about 30 weeks of pregnancy.

Tell your doctor if you are breastfeeding or plan to breast feed. Elyxyb may pass into your breast milk. Talk with your healthcare provider about the best way to feed your baby if you take Elyxyb.

Common antidepressants used for orthopedic pain relief may include SSRIs like fluoxetine (Prozac), paroxetine (Paxil), and sertraline (Zoloft), SNRIs such as duloxetine (Cymbalta), or tricyclic antidepressants (TCAs) like amitriptyline (Elavil) or nortriptyline (Pamelor). Continue reading

At lower doses, meloxicam is more similar to Celebrex (celecoxib) than it is to other NSAIDs, like ibuprofen or naproxen, because it is relatively selective for the COX-2 enzyme. But at higher doses, even within the prescribed range, meloxicam can inhibit both COX-1 and COX-2 enzymes, which may lead to side effects like stomach ulcers or bleeding. COX-2 selectivity is a dose-related effect. Continue reading
