How it works in plain English

How to take Calaptin SR 120 Mg

• Dose and timing: usually once daily. Take it at the same time every day.
• With food: you can take it with or without food. If your stomach is sensitive, a small snack helps.
• Do not crush, chew, or split sustained release tablets. Swallow whole with water.
• Missed dose: take it when you remember the same day. If it is close to the next dose, skip the missed dose. Do not double up.
• Do not stop suddenly unless your clinician tells you to. Stopping abruptly can raise the risk of rebound symptoms.

What to expect

• Blood pressure and heart rate usually start improving within a few days, with full benefit over 1 to 2 weeks.
• Common effects include constipation, mild swelling of ankles, dizziness, or headache as your body adjusts.
• Keep a simple log of home blood pressure and pulse. Bring it to visits so your clinician can fine tune the plan.

Safety notes you should know

• Avoid grapefruit and grapefruit juice unless your clinician says it is safe for you. Grapefruit can raise verapamil levels.
• Tell your clinician if you have heart failure with reduced ejection fraction, very low blood pressure, a slow heart rate, second or third degree AV block, or sick sinus syndrome without a pacemaker. Verapamil may not be advised in these situations.
• Liver problems can raise medicine levels. Your prescriber may start lower and monitor closely.
• Call for fainting, severe dizziness, very slow pulse, cold sweats, chest pain that is new or worse, or shortness of breath.

Common side effects

• Constipation, nausea, or stomach upset
• Dizziness or lightheadedness, especially when standing
• Headache, fatigue, or ankle swelling
• Flushing or a slow heartbeat

Important interactions

• Beta blockers and other heart rate lowering drugs can add to slow pulse or low blood pressure. Your clinician will decide on safe combinations and doses.
• Digoxin levels can rise with verapamil. Monitoring and dose changes may be needed.
• Statins that use CYP3A4, especially simvastatin, can build up. Simvastatin is often limited to 10 or 20 mg daily with verapamil. Ask about safer statin choices.
• CYP3A4 inhibitors such as clarithromycin, erythromycin, azole antifungals, and HIV protease inhibitors can raise verapamil levels. Rifampin can lower them.
• Alcohol can intensify dizziness and lower blood pressure further. Keep intake modest.
• Always share a full list of prescriptions, OTC medicines, and supplements.

Practical tips that help

• Take it at the same time daily. Set a phone reminder while you build the habit.
• Stand up slowly from sitting or lying down, especially the first week.
• Keep meals balanced and salt steady. Big swings in salt can affect blood pressure.
• Pair medicine with the basics: regular movement, weight management, and good sleep improve results.
