Dynacirc CR (Isradipine CR) and/or alternatives

General Information On Dynacirc CR

Dynacirc CR (generic name: Isradipine ER) is usually prescribed along with thiazide diuretics in order to treat high blood pressure. Isradipine ER belongs to the group of calcium channel blockers, which widen your arteries so that blood can flow through them more easily. You can buy Dynacirc CR in the form of oral capsules with 2.5mg and 5mg strengths. Though this drug helps in keeping your high blood pressure in check, it cannot cure the condition, and so, you may need to take this drug in the long term, even if you are not feeling sick.

Side Effects for Dynacirc CR

Dizziness, warmth, a tingly feeling or redness under the skin, headache, tiredness, weakness, nausea, diarrhea, vomiting, upset stomach, itching, or skin rash are some of the commonly experienced side effects of Dynacirc CR. However, you need to inform your doctor if you experience shortness of breath, swelling on the hands or feet, chest pain, or pounding and fast heartbeat. Sometimes, you may see an empty capsule shell in your stools, but this is not harmful as the medicine has already been absorbed in your body. You should immediately stop using Dynacirc CR and notify your doctor if you have severe constipation or abdominal pain or notice changes in your vision like double vision, blurred vision, or complete vision loss. An allergic reaction to the medicine is rare, but it can be identified by hives, rash, swelling or itching of the face, throat, tongue, or lips, breathing trouble, and severe dizziness. In that case, you should discontinue using Dynacirc CR and seek medical help.

Precautions

You should inform your doctor if you are suffering from a liver or kidney disease, congestive heart failure, or blockage or narrowing of the digestive tract. If you have any of these conditions, your doctor will need to conduct special tests or make dosage adjustments while recommending Dynacirc CR. Your doctor will also not ask you to buy Dynacirc CR if you are pregnant or breastfeeding unless extremely necessary. Apart from that, you should not consume grapefruit or grapefruit juice, as doing so may increase the amount of the medicine in your blood and result in low blood pressure. In order to prevent dizziness as a side effect of Dynacirc CR, you should try to get up from a lying or sitting position slowly, without a jerk.

Dynacirc CR Dosage

The medication usually starts with Dynacirc CR 5mg daily divided into 2 doses of Dynacirc CR 2.5mg 2 times a day. The capsule needs to be swallowed whole, without breaking, opening, crushing or chewing it. The increment in the dosage depends on your medical condition and response to treatment, and you need to take the medicine in the long term, as it only helps in controlling blood pressure, not curing it. Your blood pressure will remain under control as long as you are taking this medicine, and it will come back to its normal level if you stop taking it.

Interactions

Some medicines that may react with Dynacirc CR include azole antifungals, rifamycins, macrolide antibiotics, and anti-seizure medications. Cimetidine is used for treating excessive stomach acid, and thus, may interact with Dynacirc CR. Therefore, you should consult your doctor before taking the two drugs together. You should also not take other drugs that decrease your blood pressure, as taking two medications to lower blood pressure can prove fatal.
