Interactions between your drugs

Moderate

olmesartan pretomanid

Applies to: hydrochlorothiazide / olmesartan and pretomanid

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with pretomanid may significantly increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of organic anion transporter 3 (OAT3). The proposed mechanism, based on in vitro data, is decreased clearance due to pretomanid-mediated inhibition of OAT3. No clinical interaction studies have been conducted in humans with OAT3 substrates.

MANAGEMENT: Caution is advised if pretomanid is used concomitantly with drugs that are substrates of OAT3, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring of the OAT3 substrate drug should be considered whenever pretomanid is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Moderate

olmesartan food

Applies to: hydrochlorothiazide / olmesartan

If you are taking olmesartan you should avoid potassium-containing salt substitutes or over-the-counter potassium supplements without first talking to your doctor. This can cause high levels of potassium in your blood. High levels of potassium can cause weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs. Call your doctor at once if you have any of these symptoms.

Moderate

pretomanid food

Applies to: pretomanid

Food can enhance the levels of pretomanid in your body. Pretomanid should be taken just after eating food. Do not take it on an empty stomach. This will make it easier for your body to absorb the medication. Swallow tablets whole. Do not crush, chew, or break the tablets.

Moderate

hydroCHLOROthiazide food

Applies to: hydrochlorothiazide / olmesartan

HydroCHLOROthiazide and ethanol (alcohol) may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. 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.
