Hi , Im 41-bipolar(among other conditions) and take lamictal (lamotigine) 300mg. I have been on it for 4or 5 years cant remember (have a bad memory)

Lamotrigine can interact with valproic acid. When lamotrigine is begun in patients already receiving valproic acid, the blood concentrations of valproic acid can decrease over a 3-week period. This may result in loss of seizure control. The risk of severe skin rash may be increased by combining lamotrigine with valproic acid.

There may be a higher incidence of dizziness, double vision, and blurred vision in patients receiving carbamazepine together with lamotrigine

Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Carbamazepine
Desogestrel
Escitalopram
Estradiol Cypionate
Ethinyl Estradiol
Ethynodiol Diacetate
Etonogestrel
Ginkgo
Levonorgestrel
Lopinavir
Mestranol
Methsuximide
Norethindrone
Norgestimate
Norgestrel
Oxcarbazepine
Phenobarbital
Primidone
Rifampin
Risperidone
Ritonavir
Rufinamide
Sertraline
