About REACTIVE CAPSULE

REACTIVE CAPSULE belongs to the class of drugs known as analgesics and muscle relaxants. It is primarily indicated for the relief of severe skeletal muscle spasms associated with painful conditions such as low back pain, sprain, strain, myalgia (muscle pain), headache, traumatic muscle injuries, cervical root and disc syndrome, torticollis (neck muscle contractions), and fibrositis (pain and inflammation of muscles). Muscle spasms are involuntary contractions of muscle, which can be painful.

REACTIVE CAPSULE is a combination of two drugs: Paracetamol (Analgesic) and Chlorzoxazone (Muscle relaxant). Paracetamol works by inhibiting the synthesis of prostaglandins, which are responsible for pain and inflammation. Chlorzoxazone acts on the brain and spinal cord centres, where it inhibits the multisynaptic reflex involved in muscle spasms, thereby providing relief from skeletal muscle spasms. Together, REACTIVE CAPSULE helps in relieving musculoskeletal pain.

You are advised to take REACTIVE CAPSULE for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects, such as gastrointestinal disturbances, nausea, dizziness, drowsiness, weakness, and light-headedness. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.

REACTIVE CAPSULE contains paracetamol; do not take any other medicines containing paracetamol along with REACTIVE CAPSULE unless prescribed. Consult your doctor if you are pregnant or breastfeeding. REACTIVE CAPSULE is not recommended for children as safety has not been established. Avoid consuming alcohol along with REACTIVE CAPSULE as it could increase the risk of stomach bleeding. REACTIVE CAPSULE may cause drowsiness and dizziness, so drive only if you are alert. Keep your doctor informed about your health condition and medicines to rule out any side effects/interactions.
