Leflunomide Side Effects
Leflunomide, as any other medicine, may cause certain side effects. That is why it is important to be aware of the most common leflunomide side effects. Whether you occur to have some of them or not depends on many factors: other medications you are currently taking, your lifestyle, diet, age, other chronic diseases or permanent conditions, etc. It is very important to be extremely attentive to your overall health condition and any minor changes that occur when you start taking leflunomide (this rule refers to any other medication!). Always inform your med prescriber about all leflunomide side effects that you experience, even though leflunomide side effects are generally reversible and not severe.
