Prometrium 100mg, while generally well-tolerated, can cause side effects. These vary in frequency and severity. Common side effects include drowsiness, dizziness, headache, and nausea. Less frequent but still possible side effects are breast tenderness, mood changes, and vaginal bleeding. A small percentage of users experience more serious reactions.
Serious Side Effects
Rare but serious side effects necessitate immediate medical attention. These include allergic reactions (rash, hives, difficulty breathing, swelling of the face, lips, tongue, or throat), severe abdominal pain, jaundice (yellowing of the skin or eyes), and unusual vaginal bleeding. If you experience any of these symptoms, contact your doctor immediately. The medication may interact with certain other drugs, so inform your physician about all medications and supplements you’re taking.
Risks and Precautions
Women with a history of blood clots, stroke, or heart disease should discuss the risks with their doctor before starting Prometrium. The medication might increase the risk of these conditions in susceptible individuals. Pregnant women should use it only under strict medical supervision. Similarly, breastfeeding mothers need to consult their physician as Prometrium may pass into breast milk. Always follow your doctor’s instructions precisely for safe and effective use.
