Can Using Nicotine Replacement Cause An Irregular Period?
The noted side effects for Nicoderm CQ according to their official website which some users may experience include irregular heartbeat or palpitations, skin redness caused by the patches, swelling in the skin, nausea, vomiting, dizziness or weakness. Other independent websites such as this one here list similar side effects as well as others but not any effects to do with the menstrual cycle. It does however note that “If you notice other effects not listed above, contact your doctor or pharmacist” which is pretty much which boat you are in. I would say that it is your best bet, to at least put your mind at ease and make sure everything is OK with you.
