How long does treatment for polymyalgia rheumatica last?

Polymyalgia rheumatica (PMR) requires a careful, long-term treatment plan. Generally, corticosteroid treatment lasts for about two years, although many patients notice a significant improvement in symptoms, such as stiffness and pain, within just a few days of starting medication [4]. It is essential to understand that this rapid improvement does not mean a complete cure; rather, it indicates that the medication has begun to suppress the inflammation caused by the disease [4].

The Steroid Treatment Journey and Management

The primary treatment relies on a type of steroid called "prednisolone," which works by inhibiting the chemicals responsible for inflammation within the body [4]. This treatment is not initially intended to permanently eradicate the disease, but rather to control the severity of symptoms affecting the neck, shoulders, and hips, which are often worse after periods of rest [3]. During the treatment period, which may last for two years, the physician will gradually taper the doses every month or two, provided the patient responds well and symptoms remain under control [4]. You can find more details about the nature of these symptoms and how to manage them in our dedicated article on Polymyalgia Rheumatica: Shoulder and Hip Stiffness and Pain (Arabic).

Importance of Follow-up and Periodic Exams

Regular medical follow-up is a fundamental pillar of a successful treatment plan. Physicians need to monitor the body's response to treatment and ensure there are no complications resulting from long-term steroid use [4]. The follow-up process includes regular blood tests to measure inflammation levels, such as the C-reactive protein (CRP) test or the erythrocyte sedimentation rate (ESR) test [1]. Decreasing levels in the blood are a positive indicator that the treatment is working correctly and that inflammation in the body is in remission [1]. It is usually recommended to schedule appointments every few weeks for the first three months, then once every three months during the first year [4].

Risks of Sudden Discontinuation and Relapses

It must be strongly emphasized that one should not stop taking steroid medications suddenly or without consulting a physician, as this can lead to a severe deterioration in health status [4]. There is also a possibility of symptoms returning, known as a "relapse," even after improvement begins. In some cases, the physician may prescribe additional medications, such as immunosuppressants (e.g., methotrexate), to help control the condition if relapses recur or if the patient does not respond sufficiently to steroids alone [4].

Signs Requiring Immediate Medical Attention

Although steroids are effective, they can be associated with side effects that require caution. Patients should contact their doctor immediately if changes in mood occur, such as depression, severe anxiety, or negative thoughts [4]. Urgent medical care should also be sought if any of the following occur:

• Thoughts of self-harm or ending one's life (seek emergency care immediately) [4].
• Exposure to the varicella-zoster virus (the cause of chickenpox or shingles), as infection risks increase with steroid use [4].
• Appearance of new, unusual symptoms or severe worsening of pain during the treatment period [4].
