Lyflex, also known by its generic name baclofen, is a medication primarily used to treat muscle spasticity. It works by acting on the central nervous system to relax muscles, which can be particularly beneficial for individuals suffering from conditions such as multiple sclerosis, spinal cord injuries, or other neurological disorders that cause muscle spasms and tightness. Lyflex is available in tablet form and sometimes as an injectable solution for more direct administration. It is important for patients to follow their healthcare provider's instructions closely when taking Lyflex, as the dosage may need to be adjusted to achieve the best balance between muscle relaxation and potential side effects, which can include drowsiness, weakness, and dizziness among others.
