Levoythyroxine is a commonly subscribed drug used for people suffering with hypothyroidism. Levothyroxine is inexpensive and effective for regulating the thyroid.

About Levothyroxine

Levothyroxine is used for treating hypothyroidism. Hypothyroidism is a thyroid dysfunction that causes body systems like metabolism to slow down or stop working. Levothyroxine is a hormone replacement that simulates the chemical in the body. Slow thyroid or hypothyroidism can cause patients to become tired, listless and overweight. This organ affects and regulates the adrenal glands. A minor but disturbing side effect of this hormone replacement drug is hair loss. Serious side effects that should not be ignored are obvious allergic reactions, like facial swelling. Becoming irritable, depressed or unable to sleep are side effects that have been reported. If you experience serious changes in your appetite or your weight, you should contact your doctor.

About Advil

Advil is used frequently for the treatment of minor pains and swelling of the joints. While most people have no side effects when taking Advil-brand ibuprofen, some do. Minor side effects that have been reported to the FDA have been related to gastrointestinal dysfunction. These are namely gas, diarrhoea, constipation or stomach cramps. Major side effects effect small portions of the population but can be deadly if not recognised. Obvious allergic reactions include swelling of the face or body, problems breathing and yellowing of the skin. Anyone who suffers serious side effects to Advil should stop taking the medication immediately and get medical help.


There is no documentation or research that indicates Advil and Levothyroxine interact dangerously with one another. Like any drug, Advil should be taken as directed. Levothyroxine can only be taken when prescribed by your doctor.


Consuming grapefruit when you take your Levothyroxine can slow the absorption of the hormone into your body. It's recommended that you don't drink grapefruit juice or eat grapefruit near the time you take your medication. Tell your doctor if you have had heart problems or kidney problems when taking Levothyroxine. Take the prescribed amount and don't miss a dose. Advil should be taken as directed only. Pay close to attention to other drug interactions listed on the label.


While there is no concrete evidence to support that these two drugs could have a negative side effect tell your doctor if you suspect you have. Contact your doctor if you think that you are experiencing a drug interaction by taking these two together. Share all your symptoms and ask questions.
