Q&A with Dr. Fred Lado:

1. I lost my driver’s license due to seizures. If I switch medications or add a new medication, how long will it take to demonstrate that I can drive? Is the decision up to my doctor or the State?

The rules that govern whether and when an individual may drive are set by each state (Click HERE for more information). In New York State, individuals are required to be seizure free for 12 months before they may drive. If a seizure occurred because an individual reduced a medication on the orders of a doctor, it may be possible to resume driving sooner (after receiving approval of the NY Dept. of Motor Vehicles). Switching medications does not alter the time an individual may not drive.

2. I am now on two medications, and I’ve been doing better. I still have seizures every 3 or 4 weeks. Is it risky to add a third medication at this point?

The biggest improvement in seizure control usually occurs after starting the first medication. The second medication will also usually make a noticable difference in seizure control. The third medication may also help, but less than the first two. Taking more than three medications is unlikely to improve seizure control, but may increase side-effects. The chance of side-effects, particularly drowsiness, increases with each added medication. Most side-effects are reversible, meaning they will go away after reducing or stopping the new medication. There is always a chance of rare side-effects when starting a new medication, but one has to balance the risk of further seizures against the low risk of a rare side-effect. (more…)

Switching Seizure Medications: Part I

When should you consider switching medications?

There are two circumstances when one should consider changing medications, when the medication is not completely effective in stopping seizures, and when the medication is producing unacceptable side effects.  Cost of a medication may also be a reason one must consider switching to less expensive medication.  One should not, however, switch from a well-tolerated and effective medication to a different medication just to try the newest medication, or in response to advertising, or on the advice of a friend or acquaintance, since the effectiveness and side-effects of the new medication are difficult to know in advance and may result in worse seizure control or new side effects. For those individuals taking one or two medicines who are still having seizures, your doctor may recommend adding a seizure medication rather than switching from one medication to another.  Taking more than three seizure medications, however, rarely improves seizure control but often results in more side effects. For individuals taking two or three medications, switching out one medication to try another medication is the usual recommendation.

What are the risks of switching medications?

Switching medications involves risks, namely the possibility that seizure control will worsen, or that the new medication will cause unanticipated side-effects.  Since usually one is undertaking a medication switch because of either poor seizure control or side-effects, it is sometimes difficult to know whether the possible benefit of changing medications outweighs the risk.  This is a very individualized decision, since each individuals lifestyle and seizure type are important factors.  For example, if one individual has seizures occurring several times a month, then the benefits of a medication switch outweigh the risks of worsening seizure control, since seizure control is already poor.  On the other hand, if another individual has a seizure once every 1 to 2 years, then the risk of worsening seizure control is a greater concern.  One may still want to change medications to achieve complete seizure control, for example, to obtain a driver’s license. However, this individual and their doctor may approach the switch more gradually, first adding the new medication to the old one, and then after sufficient time – even 1 or two years – gradually tapering the older medication.

Q&A with Ruth Shinnar, RN, MSN:

 

1. I’ve heard that switching between brand drugs and generics can affect a change in seizure control and patterns. Is that true? Should I be concerned about using generics?

Switching between brand drugs and generics usually does not have an effect on seizure control. Unfortunately, there is no way to determine who will be affected by switching. The Federal Drug Administration (FDA) has set manufacturing guidelines for makers of generic drugs. The generic drug manufacturer must prove its drug is the same as (bioequivalent) the brand name drug. When a drug, generic or brand name, is mass-produced, very small variations in purity, size, strength, and other parameters are permitted. FDA limits how much variability is acceptable. Most people will not be affected by this variability but some are. If you are one of these people you can be prescribed the brand name and provide evidence of need to your insurance company with the help of your health care provider.

2. My daughter has experienced significant weight gain since she started taking seizure meds. While we recognize her concern, my husband and I are afraid that switching her medications will trigger more seizures. Do you have any recommendations for teens with epilepsy who have weight issues? 

Healthy eating habits and regular exercise are encouraged for everyone but medications can cause weight gain even when eating healthy. If the weight gain is felt to be from the antiepileptic medication a change may be beneficial. There are ways to safely switch over to another medication and you can discuss how to do this with your daughter’s health care provider.

3. Although my seizures are well controlled with my medication, I do get headaches more often that I used to. Is this typical? Should I talk to my doctor?

 Headaches can be a side effect from antiepileptic medications, although it is uncommon. Your neurologist can perform a headache evaluation and should be able to determine whether your medication should be changed. (more…)
