USES
Emgality (generic name: galcanezumab) is a prescription medication used for the prevention of migraine headaches in adults. Here are the primary uses of Emgality:
Migraine Prevention
It is used to reduce the frequency and severity of migraine attacks, potentially improving the quality of life for individuals who experience chronic or episodic migraines.
Chronic Migraine
Emgality is approved for the prevention of chronic migraine, which is defined as having 15 or more headache days per month, with at least 8 of those being migraines, for at least three months.
Episodic Migraine
Emgality may also be prescribed for the prevention of episodic migraines, which are less frequent but still disruptive. Episodic migraines are characterized by having fewer than 15 headache days per month.
SIDE EFFECTS
Like all medications, Emgality may cause side effects in some individuals. It is essential to be aware of these potential side effects and consult a healthcare professional if you experience any of them.
Common Side Effects
- Injection Site Reactions: Emgality is typically administered as a subcutaneous injection.
- Headache: Ironically, one of the side effects of Emgality is a headache. However, this headache is usually mild and temporary.
- Infections: In rare cases, Emgality may increase the risk of upper respiratory tract infections, such as the common cold.
Less Common Side Effects
- Allergic Reactions: While rare, some individuals may experience allergic reactions to Emgality. Seek immediate medical attention if you develop symptoms like itching, rash, swelling, severe dizziness, or difficulty breathing.
- Constipation: Infrequent cases of constipation have been reported in individuals taking Emgality.
- Nausea: Some users may experience mild nausea as a side effect.
Individual experiences may vary, and you should always consult your healthcare provider for a comprehensive understanding of the potential side effects and their management.
WARNING
Before starting Emgality, it’s crucial to discuss your medical history and any preexisting conditions with your healthcare provider. Additionally, be aware of the following warnings and precautions associated with Emgality:
Warnings
Hypersensitivity
If you have a known hypersensitivity or allergy to galcanezumab or any of the ingredients in Emgality, you should not use this medication.
Liver Disease
Emgality should be used with caution in individuals with severe hepatic impairment.
PRECAUTIONS
Pregnancy and Breastfeeding
It is essential to inform your healthcare provider if you are pregnant, planning to become pregnant, or breastfeeding. The safety of Emgality during pregnancy and lactation is not well-established.
Pediatric Use
Emgality has not been studied in pediatric patients, and its safety and efficacy in this population have not been established.
Driving and Operating Machinery
Some individuals may experience dizziness as a side effect of Emgality. If you are affected, avoid activities that require alertness, such as driving or operating heavy machinery.
Alcohol
Be cautious when consuming alcohol while taking Emgality, as it may exacerbate certain side effects, such as dizziness.
Other Medications
Inform your healthcare provider about all the medications, supplements, and herbal products you are taking, as Emgality may interact with other drugs.
INTERCATIONS
Emgality may interact with other medications and substances, potentially affecting its efficacy or increasing the risk of side effects. It’s essential to inform your healthcare provider about all the drugs and supplements you are taking to ensure your safety and the effectiveness of treatment.
Here are some potential drug interactions to be aware of:
Other CGRP Inhibitors
Concurrent use of multiple CGRP inhibitors (e.g., Aimovig, Ajovy) may lead to an increased risk of side effects or reduced effectiveness. Combining these medications is generally not recommended unless specifically directed by a healthcare provider.
Anticoagulants: Drugs that affect blood clotting, such as warfarin or heparin, may interact with Emgality. Your healthcare provider may need to monitor your blood clotting parameters more closely if you are taking both Emgality and an anticoagulant.
CYP450 Enzyme Inducers/Inhibitors
Some drugs can affect the metabolism of Emgality by interacting with cytochrome P450 (CYP450) enzymes. For example, drugs that induce CYP450 enzymes (e.g., rifampin, phenytoin) may reduce Emgality’s effectiveness, while inhibitors (e.g., ketoconazole, fluoxetine) may increase its blood levels, potentially leading to an increased risk of side effects. Your healthcare provider can assess potential interactions and adjust your medication regimen accordingly.
Immunosuppressive Drugs
Emgality may affect the immune system to some extent. If you are taking immunosuppressive medications (e.g., corticosteroids, methotrexate), your healthcare provider should monitor you closely for potential interactions or changes in your immune response.
Other Preventive Migraine Medications
If you are taking other preventive medications for migraines (e.g., beta-blockers, antiepileptic drugs), your healthcare provider will need to assess the potential interactions and determine the best treatment plan for you.
Herbal Supplements and Over-the-Counter Medications
Even non-prescription drugs and herbal supplements can interact with Emgality.
Alcohol
While there is no specific known interaction between Emgality and alcohol, excessive alcohol consumption can trigger migraines in some individuals. Be cautious and moderate your alcohol intake if you are prone to migraines.
DOSAGE
The dosage of Emgality may vary depending on your individual circumstances and the recommendations of your healthcare provider. Emgality is typically administered as a subcutaneous injection once a month.
The recommended dose is 120 mg, followed by 240 mg as a loading dose. Subsequent monthly doses are 120 mg.
It’s crucial to follow your healthcare provider’s instructions regarding the administration and dosage schedule for Emgality.
PRESCRIPTION
Emgality is a prescription medication, which means it can only be obtained with a valid prescription from a licensed healthcare provider.
Your healthcare provider will assess your medical history, migraine frequency, and other relevant factors before determining if Emgality is an appropriate treatment for you.
When prescribed Emgality, be sure to:
Follow Instructions
Adhere to your healthcare provider’s instructions regarding the administration, dosage, and frequency of Emgality.
