Some medications can be extremely helpful for people who have had a brain injury. The amount and type of medication your child is given will depend on the stage of their brain injury. During an intensive care unit admission, children are often given many medications. These medications are stopped as soon as
it is safe to do so. The aim is for children to be on as few medications as they need.
In the acute or early stages after a brain injury, children may need to be sedated using medications such as anaesthetics, morphine and midazolam. Sedation helps to protect the brain from agitation and restlessness. Agitation raises the pressure inside the skull and is not
good for the injured brain. Some children require medications to control their blood pressure (eg beta blockers or clonidine) because the internal control mechanisms located in the brain are
temporarily out of order.
If a child has seizures soon after their brain injury, they may be given anticonvulsants (usually phenytoin or carbamazepine) and these medications may be continued for a number of months. The child may be weaned off the medication after a period of time but only if they have not had any further seizures. Other
children have anticonvulsant medication in the early days after a brain injury to protect against having a seizure. This is usually stopped before the children go home, provided that no seizures have occurred.
If a child has a lot of difficulty with muscle stiffness or spasticity, oral medications such as diazepam, baclofen or dantrolene sodium may be used. In rare instances, botulinum toxin injections can also be used to relieve localised areas of extreme stiffness.
Once discharged from hospital, only a few children need ongoing medications related to their brain injury. Before starting any medication, check with your child's GP or specialist what the side effects could be, and what positive or negative effects you should look out for
After a brain injury, some children will have difficulty with attention, concentration and distractibility. Many strategies can be used at home and in the classroom to help children with these problems before you consider medication.
Some children respond to stimulant medications such as dexamphetamine or methylphenidate. This should be trialed with careful assessments to ensure your child responds well to the medication. Involving your child's teacher in this medication trial is also important.
If your child's attention and concentration improve on stimulant medication then it is worth staying on the medication for a reasonable amount of time (eg 12 months) to make the most of this benefit. Some children take stimulant medication for many years with no long-term side effects.
Common side effects of stimulant medications include nausea, abdominal pain, anorexia (poor appetite), sometimes weight loss and difficulty sleeping. The side effects are minimised by increasing the dose slowly and giving the medication early in the day.
Some children are extremely irritable after a brain injury. It is important to determine if this is due to an inability to control their impulses, or if it is a sign of depression.
In this situation, some of the anticonvulsant medications have an additional beneficial effect of being a mood stabiliser. Carbamazepine or sodium valproate are the most commonly used drugs. Both of these medications can be very effective and are worth trying when behavioural, psychological and
environmental adjustments have not helped. These children usually start on a lower dose than what is used for seizures. If the medication is helpful it should be continued for at least six months.
These medications are usually very well tolerated by children. Side effects are varied and may include rash, nausea, weight loss or gain and vomiting. If behavioural difficulties continue, or you suspect depression as a cause of your child's irritability, then consultation with a child psychiatrist is
often required. Antidepressant medications (amitriptyline) or SSRIs (such as sertraline or fluoxetrene) may be useful.
All of the following conditions are best investigated by an endocrinologist who can also start treatment for:

Your GP or paediatrician will be the best person to rule out other causes for irritability, headache and pain. Your child may need to be seen by a rehabilitation specialist, neurologist or psychiatrist before commencing specific medications.
