Accutane/Isotretinoin can cause muscle pain
Accutane, or Isotretinoin, is a drug used to treat severe acne. It was introduced in the United States in 1982 but was taken off the market in 2010 due to safety concerns. It is now only available through a restricted distribution program approved by the FDA.
Isotretinoin has a wide range of side effects, including musculoskeletal pains such as myalgia, arthralgia, and low back pain. These musculoskeletal pains are the most common rheumatologic side effects of the drug, affecting 20% of patients. Myalgia and arthralgia have been reported in 2-5% of patients receiving oral isotretinoin >0.5 mg/kg/day. In one study, 49.5% of patients experienced musculoskeletal side effects, with 78.7% of those patients experiencing back pain. Another study found that 46.9% of patients taking isotretinoin for acne vulgaris experienced low back pain.
The drug can also cause more serious muscle problems, such as myopathy, which can manifest as muscle weakness, increased CPK levels, myalgia, myoglobinuria, and EMG and histologic changes. In rare cases, myopathy can lead to severe weakness with rhabdomyolysis, renal failure, and even death.
If you experience muscle weakness with or without pain while taking Accutane, it could be a sign of serious muscle damage, and you should stop taking the medication and contact your doctor immediately.

Accutane/Isotretinoin can cause joint pain
Accutane, also known as Isotretinoin, is a drug used to treat severe acne. It is a high-dose vitamin A pill and belongs to a group of medications known as retinoids. It has been in use for more than three decades and is known to have several side effects, including musculoskeletal adverse effects.
Isotretinoin can cause joint pain, which is one of its most common rheumatologic side effects. Arthralgia, or joint pain, has been reported in 2-5% of patients receiving oral isotretinoin at a dosage of more than 0.5 mg/kg/day. This side effect is usually mild and tends to resolve with dose reduction. However, it is important to note that musculoskeletal pains and arthralgia can be detected in up to 20% of patients taking isotretinoin.
In addition to joint pain, isotretinoin can also cause myalgia, or muscle pain. Myalgia has been reported in a small percentage of patients, ranging from 2-5% to 3% of those taking the drug. It is important to be aware of this side effect as it can be a sign of more serious muscle damage. If you experience muscle weakness along with pain, it is crucial to stop taking isotretinoin and consult a doctor immediately.
The back, particularly the lower back, is one of the most commonly affected areas by isotretinoin-induced joint and muscle pain. Studies have shown that inflammatory back pain is prevalent in patients taking isotretinoin, with some reporting back pain severity using the Visual Analog Scale (VAS). The severity of pain was classified as mild (VAS score of 1-4), moderate (VAS score of 5-6), or severe (VAS score of 7-10).
While joint pain is a known side effect of isotretinoin, it is important to consult a doctor or healthcare provider if the pain becomes unbearable or persists even after discontinuing the medication. Light exercise is generally considered safe for those experiencing isotretinoin-induced joint pain, but intense physical activity should be avoided as it may worsen the pain.

It is also used to treat folliculitis decalvans, a rare, chronic, inflammatory scalp condition that leads to scarring alopecia.

Back pain is one of the most common musculoskeletal side effects of Isotretinoin, with a reported incidence of 49.5% in one study. The back pain can be mechanical or inflammatory, with the latter being more common. Pain severity is directly correlated with increasing age, and the cumulative dose of Isotretinoin can influence pain severity.
