My son does not drink a lot of water. What are the effects of not drinking a lot of water while taking Accutane?

Accutane is a go-to medication for patients with recalcitrant cystic acne. It can reduce pore size and also reduce sebum production in your skin, making it less oily; and in turn, dryer. Accutane can be used to control acne, but patients receiving the medication should be carefully monitored. In terms of skincare, always wear an appropriate sunscreen and reduce direct sun exposure. In my patients, I recommend a good ceramide moisturizer such as Elevase whenever they are on Accutane. This will keep the skin hydrated and reduce the oiliness of the skin that is associated with oil-based moisturizers.

It is recommended that Accutane be taken with a full glass of water to prevent the capsule from dissolving in the esophagus. If the capsule were to dissolve in the esophagus this could cause irritation.

Nothing really. Accutane dries out the skin and while water does help hydrate the skin in general, it's not going to affect the Accutane course if he does or does not drink a lot of water. "This answer has been solicited without seeing this patient and
