Rose,
You probably looked at this, but here is a list of precautions for Synthroid (Levothyroxine):
What special precautions should I follow?
Before taking levothyroxine,
•
tell your doctor and pharmacist if you are allergic to levothyroxine, thyroid hormone, any other drugs, povidone iodine, tartrazine (a yellow dye in some processed foods and drugs), or foods such as lactose or corn starch. Levothroid contains lactose, while Synthroid contains tartrazine and povidone.
•
tell your doctor and pharmacist what prescript
ion and nonprescript
ion medications you are taking, especially amphetamines; anticoagulants ('blood thinners') such as warfarin (Coumadin); antidepressants or anti-anxiety agents; arthritis medicine; aspirin; beta-blockers such as metoprolol (Lopressor, Toprol), propranolol (Inderal) or timolol (Blocadren, Timoptic); cancer chemotherapy agents; diabetes medications (insulin and tablets); digoxin (Lanoxin); estrogens; methadone; oral contraceptives; phenytoin (Dilantin); steroids; theophylline (TheoDur); and vitamins.
•
if you take an antacid, calcium carbonate (Tums), cholestyramine (Questran), colestipol (Colestid), iron, orlistat (alli, Xenical), simethicone (Phazyme, Gas X), sodium polystrene sulfonate (Kayexalate), or sucralfate (Carafate), take it at least 4 hours before or 4 hours after you take levothyroxine.
•
tell your doctor if you have or have ever had diabetes; hardening of the arteries (atherosclerosis); kidney disease; hepatitis; cardiovascular disease such as high blood pressure, chest pain (angina), arrhythmias, or heart attack; or an underactive adrenal or pituitary gland.
And here is a list of the possible side effects. I see nausea and headaches, but as badly as
you feel, please let your doctor know.
What side effects can this medication cause?
Levothyroxine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
weight loss
tremor
headache
nausea
vomiting
diarrhea
stomach cramps
nervousness
irritability
insomnia
excessive sweating
increased appetite
fever
changes in menstrual cycle
sensitivity to heat
temporary hair loss, particularly in children during the first month of therapy
If you experience either of the following symptoms, call your doctor immediately:
chest pain (angina)
rapid or irregular heartbeat or pulse
