Synthroid

Synthroid, also known as levothyroxine sodium, is a prescription medication that is used to treat an underactive thyroid gland (hypothyroidism). Synthroid belongs to a class of drugs known as thyroid hormones. It works by replacing or providing more thyroid hormone, which is normally produced by the thyroid gland. This medication helps to regulate the body’s metabolism and energy levels.

Synthroid is available in tablet form for oral administration and comes in various strengths. The dosage may vary depending on the individual’s age, weight, and the severity of their condition. It is important to take Synthroid exactly as prescribed by a healthcare professional.

When Not to Take Synthroid

Synthroid should not be taken if an individual has a known allergy or hypersensitivity to levothyroxine sodium or any of the inactive ingredients present in the medication. Allergic reactions to Synthroid may include rash, itching, swelling, severe dizziness, or difficulty breathing.

Additionally, individuals with uncorrected adrenal insufficiency, untreated thyrotoxicosis (excessive thyroid hormone levels), or acute myocardial infarction (heart attack) are advised not to take Synthroid.

Synthroid Reactions

Common side effects of Synthroid may include hair loss, headache, nervousness, irritability, sleep disturbances, increased appetite, weight loss, and menstrual irregularities. These side effects are usually mild and temporary. However, if they persist or become severe, it is important to consult a healthcare professional.

In rare cases, severe allergic reactions to Synthroid may occur, characterized by symptoms such as skin rash or hives, severe itching, swelling of the face, lips, or tongue, and difficulty breathing or swallowing. Immediate medical attention should be sought if any of these symptoms are experienced.

Administration

Synthroid should be taken once a day on an empty stomach, at least 30 minutes to 1 hour before breakfast. This is because food can interfere with the absorption of the medication. It is important to swallow the tablet whole and not crush or chew it.

If a dose of Synthroid is missed, it should be taken as soon as possible. However, if it is close to the time for the next scheduled dose, the missed dose should be skipped and the regular dosing schedule resumed. Double doses to make up for a missed dose should be avoided.

An overdose of Synthroid can lead to symptoms such as chest pain, rapid or irregular heartbeat, shortness of breath, tremors, confusion, or seizures. If an overdose is suspected, emergency medical attention should be sought immediately.
