You are having a reaction to your medicine. This does not mean you are allergic to the drug. Medicines can have many different side effects and toxic reactions. These include:
Stomach symptoms, such as nausea, vomiting, cramps, diarrhea, bloating, constipation, and dry mouth.
Nervous system symptoms, such as weakness, muscle spasms, drowsiness, confusion, agitation, and headache.
Heart and blood vessel symptoms, such as fainting, irregular heartbeat (palpitations), and fast heartbeat.
Skin symptoms, such as itching, light sensitivity, and rashes.
When taking more medicines, there is an increased chance of a drug interaction that can make you sick. Take your medicines as your caregiver recommends. Keep a list of the names and doses of each of your drugs. Avoid alcohol and street drugs. Call your caregiver if you are worried about drug side effects or toxicity.
