Drug treatment for trigeminal neuralgia and trigeminal neuropathy relies primarily on antiseizure medications and antidepressants.
These medications can be highly effective, but like all medicines they may cause side effects. This is a common concern, so it is helpful to understand what to expect and why these effects should not discourage treatment.
Common Side Effects
Antiseizure medications
- Drowsiness, dizziness, brain fog
- Balance problems
- Nausea or gastrointestinal symptoms
- Swelling and weight gain
- Skin rash or allergic reactions
- Less commonly, liver abnormalities, blood count changes including leukopenia
Antidepressants
- Dry mouth and constipation
- Drowsiness or insomnia
- Dizziness and low blood pressure
- Sweating
- Appetite changes
- Weight gain
- Sexual side effects including erectile dysfunction, reduced libido, and difficulty reaching orgasm
Contraception
Some antiseizure medications, including carbamazepine, oxcarbazepine, and phenytoin, may reduce the effectiveness of hormonal contraception. Discuss additional or alternative contraceptive methods with your doctor.
Why Continue Treatment Despite Side Effects?
Side effects often improve after several days or weeks as the body adapts. Doctors usually begin with a low dose and increase it gradually. If side effects become troublesome, another medication or combination of lower-dose medications may be considered.
For many people, pain relief far outweighs the discomfort caused by side effects.
Always discuss concerns, including sexual side effects, with your doctor instead of stopping medication on your own.
Future posts will discuss supplements that may help support the body while taking antiseizure medications and antidepressants.
