Hi and thanks for the query,
the drugs prescribed most of them have anti allergic and anti inflammatory effects.Rashes or allergies are not the expected side effects from this drugs. These are drugs designed to instead fight against allergic ad hypersensitivity
reactions as a whole. Respect of the prescriptions as prescribed by your treating physician is the ideal thing to do. However, unexpected effects could rarely occur with any external case. In such an event, stop the drug and report immediately to your treating physician. For now, you need not bother.
Thanks and best regards,
