Interactions between your drugs

Moderate

ibuprofen valGANciclovir

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine and valganciclovir

Consumer information for this interaction is not currently available.

GENERALLY AVOID: The use of ganciclovir or its prodrug, valganciclovir, with other drugs associated with myelosuppression and/or nephrotoxicity may increase the risk and severity of these adverse reactions due to additive effects on the kidney and bone marrow. Valganciclovir is rapidly and extensively converted to ganciclovir, which has had the following adverse reactions observed with its treatment when used alone: severe leucopenia, neutropenia, anemia, thrombocytopenia, pancytopenia, bone marrow depression, aplastic anemia, increased serum creatinine levels, and acute renal failure. Additionally, ganciclovir is primarily renally excreted; therefore, patients with impaired renal function will have increased concentrations of ganciclovir and may be at an even greater risk of experiencing adverse reactions from treatment. Theoretically when two or more medications with similar side effect profiles are given concurrently, the likelihood of experiencing these adverse reactions may be increased.

MANAGEMENT: Ganciclovir or its prodrug, valganciclovir, should generally not be combined with other drugs associated with myelosuppression and/or nephrotoxicity unless the benefits are anticipated to outweigh the potential risks. Extreme caution is advised if they are used in patients who have recently received or are receiving treatment with myelotoxic and/or nephrotoxic drugs, and vice versa. If coadministration is required, reduced dosages of one or more of the drugs may be required, and the patient should be monitored for the development of hematologic and/or renal adverse effects both during and after discontinuation of therapy.

Drug and food interactions

Moderate

chlorpheniramine food

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine

Alcohol can increase the nervous system side effects of chlorpheniramine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with chlorpheniramine. Do not use more than the recommended dose of chlorpheniramine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Moderate

valGANciclovir food

Applies to: valganciclovir

Food can enhance the levels of valGANciclovir in your body. To ensure maximal oral absorption, valGANciclovir should be administered with or immediately after a meal. This will make it easier for your body to absorb the medication.

Moderate

ibuprofen food

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine

Ask your doctor before using ibuprofen together with ethanol (alcohol). Do not drink alcohol while taking ibuprofen. Alcohol can increase your risk of stomach bleeding caused by ibuprofen. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

pseudoephedrine food

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine

Both pseudoephedrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
