Levothyroxine 75 mg, while generally safe and effective, can cause side effects. Common ones include headache, changes in menstrual cycle, and insomnia. Less frequent but more serious effects include rapid or irregular heartbeat, weight changes (both gain and loss), and tremors. Always report any new or worsening symptoms to your doctor.
Certain foods and medications can interfere with levothyroxine absorption. Soy products, calcium supplements, and iron supplements, when taken concurrently, can reduce levothyroxine effectiveness. Maintain a consistent time between taking your medication and consuming these items–at least four hours apart is recommended.
Specific medications like antacids, cholestyramine, and certain medications for diabetes (e. g., certain types of insulin) can also impact levothyroxine absorption. Discuss all medications, including over-the-counter drugs and supplements, with your doctor or pharmacist to avoid potential interactions.
Regular monitoring of thyroid hormone levels through blood tests is crucial to ensure the medication’s effectiveness and adjust dosage as needed. Your doctor will schedule these tests to track your progress and make appropriate adjustments. This close monitoring helps minimize side effects and maximize treatment benefits.
If you experience any severe side effects, such as chest pain or shortness of breath, seek immediate medical attention.
