Otrexup (methotrexate) is a medication that can be injected into a muscle, under the skin, or infused into a vein. It is used to treat severe cases of rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, and psoriasis. While Otrexup can be effective, it has been associated with a range of side effects, from mild to severe. One of the potential side effects of Otrexup is muscle cramps or spasms. This may be related to the medication's impact on the body's bone marrow and blood cell production, which can lead to muscle weakness and other issues. It is important for patients taking Otrexup to be aware of these possible side effects and to seek medical advice if they experience any adverse reactions.

Otrexup can cause muscle cramps as a symptom of tumour lysis syndrome (TLS)
Otrexup (methotrexate) is a medication that can be injected into a muscle, under the skin, or infused into a vein. It is used to treat severe, active rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, and severe psoriasis. Otrexup can also be used to treat cancer in certain cases.
Otrexup has been known to cause serious and sometimes fatal side effects. One of these side effects is muscle weakness, which can manifest as muscle cramps or spasms. While muscle cramps can be a common symptom of physical exertion or dehydration, persistent or severe muscle cramps can be a sign of something more serious and should be evaluated by a medical professional.
In rare cases, Otrexup can cause a serious condition called tumour lysis syndrome (TLS). TLS occurs when there is a rapid destruction of cancer cells, leading to the release of their contents into the bloodstream. People with certain cancers or tumours who are prescribed Otrexup have a higher risk of developing TLS. The typical symptoms of TLS include nausea, vomiting, low appetite, tiredness, side pain, a pounding chest, dark urine, and decreased urination, in addition to muscle cramps.
If you or someone you know is experiencing muscle cramps or any other symptoms mentioned above after taking Otrexup, it is important to seek medical advice promptly. A healthcare provider will be able to assess your condition, determine if TLS or another complication is present, and provide appropriate treatment. It is crucial to follow the instructions provided by your doctor when taking Otrexup and to report any side effects, even if they seem mild.

TLS is rare, but can be fatal
Otrexup (methotrexate) is a medication that can be injected into a muscle, under the skin, or infused into a vein. It is used to treat severe, active rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, and severe psoriasis that has not responded to other treatments.
While Otrexup is an effective treatment for these conditions, it can cause a range of side effects, some of which can be serious and even fatal. One such rare but potentially fatal complication is Tumor Lysis Syndrome (TLS). TLS is a serious condition that can occur in people with certain cancers or tumors who take Otrexup. It is caused by the rapid destruction of cancer cells, which releases their contents into the bloodstream, leading to potential kidney damage and other complications.
The risk of developing TLS is typically low for people using Otrexup to treat arthritis or psoriasis, unless they have a known or undiagnosed tumor. However, if TLS does occur, it can be life-threatening, so it is crucial to recognize the symptoms and seek immediate medical attention. These symptoms include nausea, vomiting, loss of appetite, extreme tiredness, side pain, muscle cramps, a pounding chest, dark urine, and decreased urination.
If you experience any of these symptoms while taking Otrexup, it is imperative to call your healthcare provider right away. They may recommend adjustments to your medication or prescribe additional treatments to manage TLS and prevent further complications. It is important to closely monitor your health and follow your healthcare provider's instructions to ensure the best outcome.
In addition to TLS, Otrexup can cause other serious and potentially fatal side effects, including bone marrow suppression, anemia, gastrointestinal toxicity, liver damage, kidney problems, and embryo-fetal toxicity. It is crucial to be aware of these potential risks and to seek medical advice if any concerning symptoms occur.

Otrexup can cause serious or fatal toxic reactions
Otrexup (methotrexate) can cause serious or fatal toxic reactions. It is a folate analog metabolic inhibitor used to treat severe, active rheumatoid arthritis (RA) and polyarticular juvenile idiopathic arthritis (pJIA) in children. It is also used to treat severe, disabling psoriasis. Otrexup is administered through injection into a muscle, under the skin, or as an infusion into a vein.
Otrexup can cause severe or fatal toxicities, including bone marrow suppression, infection, renal, gastrointestinal, hepatic, pulmonary, hypersensitivity, and dermatologic reactions. It can also cause embryo-fetal toxicity and fetal death. Use in pregnant women is contraindicated as it can cause birth defects and death in unborn babies. Women who are pregnant or planning to become pregnant must not take Otrexup. Along with its intended effects, Otrexup may cause unwanted side effects. Although not all of these side effects may occur, if they do occur, they may need medical attention.
Otrexup can cause serious allergic and skin reactions. Get medical help right away if you experience trouble breathing, swelling in your face or throat, rash, blisters, peeling skin, red skin, mouth sores, muscle aches, or fever. Otrexup can affect your bone marrow and reduce your body's ability to fight infections. Your healthcare provider will likely monitor your blood cell counts periodically during treatment. Contact your provider immediately if you experience sudden muscle weakness, unexplained bruising or bleeding, or fever.
Otrexup may also cause serious eye symptoms such as sudden vision loss, blurred vision, tunnel vision, eye pain or swelling, or seeing halos around lights. It can also cause serious heart symptoms such as fast, irregular, or pounding heartbeats, fluttering in the chest, shortness of breath, and sudden dizziness, lightheadedness, or fainting.

Otrexup is not recommended for pregnant women
Otrexup (methotrexate) is a prescription medicine that is injected into a muscle, under the skin, or infused into a vein. It is used to treat severe, active rheumatoid arthritis (RA), and polyarticular juvenile idiopathic arthritis (pJIA) in children. It is also used to control the symptoms of severe, disabling psoriasis in adults.
Otrexup has been associated with embryo-fetal toxicity, resulting in an increased risk of death of the baby and birth defects. Published reports and studies on methotrexate's mechanism of action indicate that the drug can cause fetal harm when administered to pregnant women. As a result, Otrexup is contraindicated for pregnant women, and it is crucial to verify the pregnancy status of females of reproductive potential before initiating treatment.
Additionally, Otrexup can pass into breast milk and may harm a breastfeeding infant. Therefore, it is advised that women do not breastfeed during treatment with Otrexup and for at least one week after the final dose. The potential for serious adverse reactions, including myelosuppression, in breastfed infants further emphasizes the importance of this precaution.
In summary, Otrexup is not recommended for pregnant women due to the significant risks associated with embryo-fetal toxicity, fetal death, and congenital anomalies. Contraception and pregnancy testing are crucial considerations for both females and males taking Otrexup. Furthermore, the potential for harm to breastfed infants underscores the importance of discontinuing breastfeeding during and shortly after treatment.
