I recently started a new medication and have had a stomach ache ever since. Am I allergic to the drug?
A clear drug allergy often involves difficulty breathing or a large, encompassing rash (such as hives) - not a minor side effect like a stomach ache. Stomach pain is often a side effect of a medication and should not be confused with a true drug allergy. With that being said, it is important to keep in mind that a stomach ache is not always a normal side effect and may be a sign of something more severe such as a drug allergy. That is why you should always discuss your concerns regarding side effects/drug allergies with your physician or pharmacist.
