Dupixent (dupilumab) is a medication prescribed for inflammatory conditions such as sinusitis, asthma, and atopic dermatitis (a form of eczema). It is administered by subcutaneous injection and works by targeting a type of inflammatory protein called an interleukin. While Dupixent has been effective in treating these conditions, it has also been associated with several side effects, including injection site reactions, eye problems such as conjunctivitis, and joint pain. In rare cases, Dupixent has also been linked to muscle pain or myalgias, with some patients reporting severe muscle spasms and constant pain in their thighs, hips, and knees. This adverse effect is substantial enough in some individuals to warrant discontinuation of the medication, despite its benefits in treating their underlying condition.

What You'll Learn
Dupixent (dupilumab) is prescribed for sinusitis, asthma, and atopic dermatitis
Dupixent (dupilumab) is a prescription medicine used to treat moderate-to-severe atopic dermatitis (eczema) in adults and children aged 6 months and older. It is also used to treat adults and children aged 6 years and older with asthma that is not adequately controlled with current asthma medications. Additionally, Dupixent is prescribed for adults with nasal polyps, specifically those with chronic rhinosinusitis with nasal polyposis (CRSwNP).
Atopic dermatitis is a condition characterised by an overreactive immune system, leading to inflammation and skin problems such as eczema. Dupixent works by targeting a type of protein called an interleukin, which is involved in inflammation. By calming the immune system, Dupixent helps to reduce the frequency and severity of inflammatory episodes. This mechanism also underlies its effectiveness in treating asthma and chronic rhinosinusitis, as it can prevent severe asthma attacks and reduce oral corticosteroid requirements in these conditions.
Dupixent is administered through injection, and it is considered a specialty medicine due to its specific storage requirements. It is important to consult a doctor before starting Dupixent to discuss any potential benefits and risks, as well as any existing medical conditions and medications.
While Dupixent has been shown to be effective in treating these conditions, it is associated with certain side effects. The most common side effects include injection site reactions, such as redness, pain, and swelling. Other possible side effects include eye problems like conjunctivitis, blepharitis, dry eyes, itchy eyes, and keratitis. Additionally, Dupixent has been linked to joint pain, with some cases of acute arthritis and arthralgia reported as adverse reactions to the medication. While the exact reason for Dupixent causing joint pain is not fully understood, experts suspect it may be related to the inhibition of certain interleukins, enhancing inflammation in the joints.

Joint pain is a common side effect of Dupixent
Several cases have been reported where patients experienced joint pain after taking Dupixent. For example, a 38-year-old woman developed severe joint pain and morning stiffness in one ankle within days of her first dose, which then spread to her knees, hips, and elbows. Similarly, a 40-year-old man who had been taking Dupixent for 16 weeks experienced generalized joint pains and morning stiffness, resulting in a decline in mobility. In another case, a 32-year-old man with atopic dermatitis developed generalized joint pain after his fourth injection of Dupixent, and the pain worsened with each subsequent injection.
The exact mechanism behind Dupixent causing joint pain is not fully understood. However, experts suspect that it may be related to the drug's inhibition of interleukins IL-4 and IL-13, which could enhance IL-17-mediated inflammation in the joints. This inflammation is believed to be the cause of the joint pain experienced by some individuals taking Dupixent.
It is important to note that not everyone who takes Dupixent will experience joint pain. In some cases, patients have been able to continue taking the medication with mild symptoms. However, if you experience joint pain while taking Dupixent, it is recommended to consult your doctor or pharmacist. They can suggest ways to manage the pain, such as applying cold or hot packs to the affected joints. Additionally, naproxen or methotrexate may be prescribed to treat Dupixent-associated joint pain. If the pain persists or becomes severe, discontinuing Dupixent may be considered.
While joint pain is a known side effect of Dupixent, it is important to weigh the risks and benefits of the medication. In some cases, patients have reported that the clinical benefits of Dupixent in managing their inflammatory conditions outweighed the joint pain. Therefore, it is crucial to work closely with your healthcare provider to find the right treatment plan for your specific needs.

Dupixent can cause weight gain
While the product information for Dupixent does not list weight gain as a side effect, several sources suggest that it can cause weight gain. A case series of 12 people prescribed Dupixent reported an average weight gain of 6.1kg over one year – the amount of weight gained ranged from 0.1kg to 18.0kg. Blog sites also report weight gain as a side effect. However, it is not known how Dupixent causes weight gain.
Dupixent (generic name: dupilumab) is a medication prescribed for inflammatory conditions such as asthma, sinusitis, and atopic dermatitis. It is administered by subcutaneous injection and works by targeting a type of protein called an interleukin, which is involved in inflammation. By inhibiting certain interleukins, Dupixent calms an overreactive immune system, reducing the frequency and severity of inflammatory episodes.
Despite its effectiveness in treating inflammatory conditions, Dupixent has been associated with various side effects, including injection site reactions and eye problems such as conjunctivitis, blepharitis, dry eyes, itchy eyes, and keratitis. These eye problems are believed to be caused by Dupixent blocking interleukin-13 (IL-13), an inflammatory protein that stimulates the production of mucus-producing goblet cells in the eye.
In addition to weight gain and eye problems, Dupixent has been linked to joint pain and muscle spasms in some patients. While not everyone experiences these side effects, they can be significant enough to impact mobility and quality of life, sometimes leading to the discontinuation of Dupixent. It is suspected that Dupixent may enhance IL-17-mediated inflammation, particularly in the joints, leading to joint pain.
It is important for patients to be informed about the potential side effects of Dupixent, including weight gain, and to discuss any new symptoms with their doctor or pharmacist. While Dupixent can be effective in treating inflammatory conditions, managing its side effects is crucial to ensure the best outcome for patients.

Dupixent may cause eye problems such as conjunctivitis and blepharitis
Dupixent (dupilumab) is a medication that is administered by subcutaneous injection. It is prescribed for inflammatory conditions such as asthma, sinusitis, and atopic dermatitis. Like all medications, Dupixent can cause certain side effects, including injection site reactions and eye problems.
Dupixent is associated with several different eye problems, including conjunctivitis, blepharitis, dry eyes, itchy eyes, and keratitis. Conjunctivitis is the most common side effect, reported in 10% of people, according to product information. However, other sources suggest a higher percentage, with 16% of patients in clinical trials reporting conjunctivitis over a 52-week treatment period. Conjunctivitis is an inflammation of the conjunctiva, which is the layer that covers the white part of the eye. It can be caused by allergies, bacteria, or viruses.
Blepharitis, another possible side effect of Dupixent, is an inflammation along the edges of the eyelids. It is reported by less than 1% of people, according to product information. However, it is still a common enough side effect that it is listed as such. Blepharitis can cause symptoms such as eye pain, red eyes, watery eyes, a gritty feeling in the eyes, and sensitivity to light.
If you experience any eye-related problems while taking Dupixent, it is important to talk to your doctor as soon as possible. Certain eye issues can lead to long-term problems if left untreated. For example, severe or untreated keratitis can result in vision loss. Your doctor will likely examine your eyes and recommend the best treatment option to manage any side effects. Artificial tears and antihistamines may work for milder eye side effects, while stronger cases might require topical corticosteroids or cyclosporine eye drops.

Muscle pain and spasms are rare side effects of Dupixent
Dupixent (dupilumab) is a medication prescribed for inflammatory conditions such as sinusitis, asthma, and atopic dermatitis or eczema. It is administered by subcutaneous injection every two or four weeks. While it is an effective treatment for many, it can cause certain side effects, including injection site reactions, eye problems, and joint pain.
Dupixent works by targeting a type of protein called an interleukin, which is involved in inflammation. By inhibiting interleukins IL-4 and IL-13, Dupixent may enhance IL-17-mediated inflammation, particularly in the joints. This is thought to be the cause of joint pain in some patients. However, muscle pain and spasms are also rare side effects of Dupixent.
In one case, a patient with atopic dermatitis reported severe myalgias and muscle spasms within one month of starting Dupixent. The muscle pain was described as a constant, bilateral pain in the thighs, which was distinct from the joint pain experienced in the hips and knees. This pain impacted the patient's sleep and daily lifestyle, and they decided to discontinue Dupixent despite its effectiveness in treating their dermatitis.
Another patient experienced a rare development of severe dupilumab-associated myalgias within one month of treatment. They also chose to stop Dupixent, even though it had benefited their atopic dermatitis exacerbation. While rare, these cases demonstrate that muscle pain and spasms can occur as adverse effects of Dupixent and significantly impact a patient's quality of life.
If you experience muscle pain or spasms while taking Dupixent, it is important to consult your doctor or pharmacist. They can help determine if your symptoms are related to the medication and provide guidance on managing or treating your symptoms.
