Lamotrigine, available under brand names like Lamictal, is prescribed for certain types of seizures and to stabilize mood in adults with bipolar disorder. A common question is whether it causes tiredness, which is a recognized side effect. This article explores why Lamotrigine may lead to tiredness, offers strategies for managing this effect, and clarifies when to consult a healthcare professional.
Lamotrigine’s Effect on Energy
Tiredness is a common side effect of Lamotrigine. It can manifest as feeling groggy or more fatigued than usual, especially when starting the medication or after a dosage increase. Lamotrigine works by stabilizing electrical activity in the brain, inhibiting voltage-sensitive sodium channels in neurons, and reducing excitatory neurotransmitters like glutamate.
This calming effect on overactive nerves can contribute to a sedating sensation. While it helps prevent seizures and stabilize mood, this stabilization can also slow central nervous system activity. Individual responses vary; some experience noticeable tiredness, while others do not. The severity can also be dose-dependent, with higher doses sometimes leading to more pronounced effects.
Coping with Tiredness
Managing tiredness while taking Lamotrigine involves several practical strategies. Establishing a consistent sleep schedule and practicing good sleep hygiene can help. This includes ensuring your bedroom is dark, quiet, and cool, and avoiding stimulating activities before bedtime.
Regular, moderate exercise can improve energy levels and sleep quality, but avoid intense workouts close to bedtime. Maintaining a balanced diet and staying well-hydrated supports overall well-being and can mitigate fatigue. Be cautious with other substances that cause drowsiness, such as alcohol, as combining them with Lamotrigine can intensify tiredness.
If tiredness is bothersome, discuss medication timing with your healthcare provider; taking it at a different time may reduce daytime drowsiness. Any adjustments to your medication schedule or dosage should only be made under a doctor’s guidance.
When to Seek Medical Advice
While some tiredness is expected with Lamotrigine, certain situations warrant immediate medical consultation. Contact your healthcare provider if you experience severe fatigue that significantly interferes with daily activities, work, or quality of life.
A sudden onset of extreme tiredness, especially with other concerning symptoms, should also prompt a medical review. Be alert for tiredness combined with signs like a rash, fever, swollen lymph nodes, or unusual bruising or bleeding. These could indicate a more serious reaction requiring prompt attention. Only a doctor can assess if tiredness relates to Lamotrigine, another health issue, or necessitates a treatment plan change.
