Ursodeoxycholic acid has been used successfully as a treatment for cases with liver involvement. Thalidomide has also been tried successfully as a treatment for treatment-resistant lupus pernio in a clinical trial, which may stem from its anti-TNF activity, although it failed to exhibit any efficacy in a pulmonary sarcoidosis clinical trial. Cutaneous disease may be successfully managed with antimalarials (such as chloroquine and hydroxychloroquine) and the tetracycline antibiotic, minocycline. Antimalarials have also demonstrated efficacy in treating sarcoidosis-induced hypercalcemia and neurosarcoidosis. Long-term use of antimalarials is limited, however, by their potential to cause irreversible blindness and hence the need for regular ophthalmologic screening. This toxicity is usually less of a problem with hydroxychloroquine than with chloroquine, although hydroxychloroquine can disturb the glucose homeostasis.

Recently selective phosphodiesterase 4 (PDE4) inhibitors like apremilast (a thalidomide derivative), roflumilast, and the less subtype-selective PDE4 inhibitor, pentoxifylline, have been tried as a treatment for sarcoidosis, with successful results being obtained with apremilast in cutaneous sarcoidosis in a small open-label study. Pentoxifylline has been used successfully to treat acute disease although its use is greatly limited by its gastrointestinal toxicity (mostly nausea, vomiting, and diarrhea). Case reports have supported the efficacy of rituximab, an anti-CD20 monoclonal antibody and a clinical trial investigating atorvastatin as a treatment for sarcoidosis is under-way. ACE inhibitors have been reported to cause remission in cutaneous sarcoidosis and improvement in pulmonary sarcoidosis, including improvement in pulmonary function, remodeling of lung parenchyma and prevention of pulmonary fibrosis in separate case series'. Nicotine patches have been found to possess anti-inflammatory effects in sarcoidosis patients, although whether they had disease-modifying effects requires further investigation. Antimycobacterial treatment (drugs that kill off mycobacteria, the causative agents behind tuberculosis and leprosy) has also proven itself effective in treating chronic cutaneous (that is, it affects the skin) sarcoidosis in one clinical trial. Quercetin has also been tried as a treatment for pulmonary sarcoidosis with some early success in one small trial.

Because of its uncommon nature, the treatment of male reproductive tract sarcoidosis is controversial. Since the differential diagnosis includes testicular cancer, some recommend orchiectomy, even if evidence of sarcoidosis in other organs is present. In the newer approach, testicular, epididymal biopsy and resection of the largest lesion has been proposed.

As the granulomas are caused by collections of immune system cells, particularly T cells, there has been some success using immunosuppressants (like cyclophosphamide, cladribine, chlorambucil, and cyclosporine), immunomodulatory (pentoxifylline and thalidomide), and anti-tumor necrosis factor treatment (such as infliximab, etanercept, golimumab, and adalimumab).

In a clinical trial cyclosporine added to prednisone treatment failed to demonstrate any significant benefit over prednisone alone in people with pulmonary sarcoidosis, although there was evidence of increased toxicity from the addition of cyclosporine to the steroid treatment including infections, malignancies (cancers), hypertension, and kidney dysfunction. Likewise chlorambucil and cyclophosphamide are seldom used in the treatment of sarcoidosis due to their high degree of toxicity, especially their potential for causing malignancies. Infliximab has been used successfully to treat pulmonary sarcoidosis in clinical trials in a number of persons. Etanercept, on the other hand, has failed to demonstrate any significant efficacy in people with uveal sarcoidosis in a couple of clinical trials. Likewise golimumab has failed to show any benefit in persons with pulmonary sarcoidosis. One clinical trial of adalimumab found treatment response in about half of subjects, which is similar to that seen with infliximab, but as adalimumab has better tolerability profile it may be preferred over infliximab.

Uveoparotitis is a symptom of sarcoidosis. It describes a chronic inflammation of the parotid gland and uvea. There is also a phenomenon called Waldenström's uveoparotitis. In this case, the symptom is related to Heerfordt's syndrome.

In patients that have already been diagnosed with sarcoidosis, Heerfordt syndrome can be inferred from the major symptoms of the syndrome, which include parotitis, fever, and facial nerve palsy. In cases of parotitis, ultrasound-guided biopsy is used to exclude the possibility of lymphoma. There are many possible causes of facial nerve palsy, including Lyme disease, HIV, Melkersson–Rosenthal syndrome, schwannoma, and Bell's palsy. Heerfordt syndrome exhibits spontaneous remission. Treatments for sarcoidosis include corticosteroids and immunosuppressive drugs.

Heerfordt syndrome, also referred to as uveoparotid fever, Heerfordt–Mylius syndrome, Heerfordt–Waldenström syndrome, and Waldenström's uveoparotitis, is a rare manifestation of sarcoidosis. The symptoms include inflammation of the eye (uveitis), swelling of the parotid gland, chronic fever, and in some cases, of the facial nerves.
