Can I take Allopurinol and Atenolol together?

You can usually take allopurinol y atenolo together, but you should be vigilant as there is a potential for these two medicines to interact.

Contact your doctor immediately if you develop a skin rash, hives, or any signs of an allergic reaction (such as swelling of the face or difficulty breathing). Your doctor may want to monitor your kidney function with routine blood tests.

Por qué sucede esto

Both allopurinol and atenolol are cleared from the body through the kidneys. It is thought that taking them together might slightly alter how the kidneys process the drugs, or trigger an overactive immune response in sensitive individuals.

You may be experiencing an interaction between allopurinol and atenolol if:

• You feel dizzy, lightheaded, or faint, especially when standing up.

• You notice unusually slow heart rate or palpitations.

• You experience tiredness, weakness, or fatigue.

• You have shortness of breath or swelling in the ankles or feet.

• You develop rashes, itching, or other allergic-type reactions.

• Symptoms appear shortly after starting or adjusting the dose of either medicine.
  

Si tienes alguno de los síntomas mencionados, deberías:

• Contacte a su médico de cabecera o farmacéutico para obtener asesoramiento lo antes posible.

• Do not stop taking allopurinol or atenolol suddenly unless instructed by a healthcare professional.

• Seek urgent medical help if you experience severe dizziness, fainting, or shortness of breath.

• Informe a su profesional de la salud sobre todos los demás medicamentos y suplementos que está tomando.

• Attend any monitoring or blood tests recommended to check heart rate, blood pressure, or kidney function.

Asma o EPOC

Atenolol can cause severe breathing difficulties or trigger a life-threatening asthma attack, even if your condition is mild. You must not take this medicine if you have a history of asthma.

Severe skin rash

Deje de tomar alopurinol inmediatamente y busque ayuda médica urgente si desarrolla una erupción cutánea, descamación de la piel o úlceras en la boca. Esto puede ser un signo de una reacción alérgica rara pero potencialmente mortal.

Abrupt withdrawal

Do not stop taking atenolol suddenly. Doing so can cause a rapid heart rate, a sharp rise in blood pressure, or trigger a heart attack. Your dose must be reduced gradually under medical supervision.

Acute gout attack

Do not start allopurinol during a sudden gout attack, as it can make the pain worse. If you have an attack while already taking it, continue your regular dose but treat the pain separately.

Alcohol

Alcohol can increase the levels of uric acid in your blood, making allopurinol less effective at preventing gout attacks. It is best to limit or avoid alcohol, especially beer and spirits.

It is best to avoid or strictly limit alcohol while taking atenolol. Alcohol can increase the blood-pressure-lowering effect of the medicine, which may make you feel dizzy, lightheaded, or faint, especially when standing up.

Orange and apple juice

Drinking large amounts of orange or apple juice may reduce the amount of atenolol absorbed by your body, potentially making it less effective. It is recommended to avoid drinking these juices in large quantities or to wait at least 2 hours between drinking them and taking your medicine.

Water / Fluids

It is important to drink plenty of fluids (at least 2 to 3 litres a day) while taking allopurinol. This helps to prevent the formation of kidney stones and ensures the medicine works correctly to flush uric acid from your system.
