The use of some of the most commonly prescribed medications are designed to assist with some of the symptoms that the tumor or the treatment can cause.
Corticosteroid drugs are used to reduce brain swelling. Swelling is common with brain tumors. Dexamethasone is most often used. It is given by mouth or IV. Decreasing swelling associated with brain tumors is the most effective way to decrease head pain.
Possible side effects include: Feeling of hunger and associated weight gainAcneMuscle weakness (steroid myopathy)—most noticeable when rising from a seated position or going up stairsInsomniaIncreased blood sugarIncreased blood pressureRestlessness (less common)
Steroids also increase your risk of developing
ulcers. Often, your doctor will place you on an additional medication to decrease this risk. Steroids are also associated with joint aching and an increased risk for
Medications to control brain swelling are usually used short-term, avoiding the majority of side effects. Your doctor will often taper you off the corticosteroids slowly.
Anti-epileptic medication are chosen based on the potential benefits and the risks of side effects. The potential interactions with your other medication will also be considered. In any given case, one may work better than another.
Many of the anti-epileptic medication have the potential to interact with your other medication, including chemotherapies.
Possible side effects for carbamazepine include: Bone marrow damageMental status changesRashes/possibly severe skin reactionsLow sodium level in the blood—hyponatremia
Possible side effects for valproic acid include: Liver damageFetal damage if pregnantPancreatitisPersistent decrease in the number of blood platelets—thrombocytopeniaWeakness, sleepinessLightheadednessNausea, vomitingDiarrheaIndigestion, abdominal pain, loss of appetiteVisual disturbancesHair lossRespiratory infectionWeight gainRashes
Possible side effects for phenytoin include: Mental status changesRashesNausea, vomiting
constipationLiver and bone marrow damageGum swellingRespiratory inflammations
Possible side effects for levetiracetam include: Mental status changesIrritabilityLoss of contact with reality—psychosisRashes
NSAIDs in higher doses, including: IndomethacinNaproxenCelecoxib
Each NSAID has a slightly different chemistry and side effect profile. NSAIDs are used primarily to control pain. They do not control swelling as well as the steroid drugs, and they have side effects of their own.
Possible side effects include: Stomach irritation, ulceration, and bleedingAllergic reactionsKidney damageLiver damage
There is no substitute for opioids in the treatment of severe pain. However, these drugs are addicting and the potential for opioid abuse is high.
Possible side effects include: LightheadednessSleepiness/SomnolenceNausea and vomitingItchinessConstipationAllergic reactionsDecreased respiratory driveOverdose—can lead to death
NSAIDs in lower doses
Possible side effects include: Stomach irritationUlcerationBleedingAllergic reactionsKidney damageLiver damage
Acetaminophen is the common pain killer used for mild-to-moderate pain. Possible side effects include allergic reactions that damage blood cells or cause rashes. Overdoses can damage the liver. Because brain tumors grow, a medication that works at first may not do so as the tumor enlarges. Doses may have to be increased or stronger medications used.
