Can the head hurt after Asertin, there be a "gula" in the throat and trembling hands?

Yes, headaches, a lumpy sensation in the throat and trembling hands may be potential side effects of using Asertin (sertraline), especially at the beginning of treatment. The occurrence of these side effects is usually temporary. Side effects occur most often in the first or second week of treatment. Their severity and incidence decrease with continued treatment. However, if the side effects are particularly bothersome or persist longer, you should consult your doctor to assess the situation and, if necessary, adjust the dose or change to another drug.
