Uses of Calmtack Injection

Benefits of Calmtack Injection

Treatment of Epilepsy
Calmtack 10mg Injection slows down electrical signals in the brain which cause seizures (fits). It can also help reduce symptoms such as confusion, uncontrollable jerking movements, loss of awareness, and fear or anxiety. The medicine can allow you to do some activities that you would otherwise be forbidden or scared to do (such as swimming and driving). It can take a few weeks for this medicine to work (because the dose has to be increased slowly) and during this time you may still have seizures.

Treatment of Short term anxiety
Calmtack 10mg Injection reduces the symptoms of excessive anxiety and worry that are triggered only at the time of stressful conditions that last for a shorter duration. These could be job interviews, exams, stage performances, etc. It can effectively manage feelings of restlessness, tiredness, difficulty concentrating and feeling irritable. Calmtack 10mg Injection will therefore help you go about your daily activities more easily and be more productive.

Treatment of Alcohol withdrawal
Calmtack 10mg Injection is a medicine used, along with social support and counseling, to help people recover from alcohol addiction and to avoid having the urge to drink alcohol again. Calmtack 10mg Injection starts working from the very first dose and is a very safe and effective way of treating alcohol addiction.

Treatment of Muscle spasm
Calmtack 10mg Injection effectively relieves muscle stiffness or spasm, thereby improving muscle movement. Take it as prescribed by the doctor to get the most benefit. Do not take more or for longer than needed as that can be dangerous and it also has habit-forming potential. In general, you should take the lowest dose that works, for the shortest possible time. This will help you to go about your daily activities more easily and have a better, more active, quality of life.
