Can you drink alcohol while taking aciclovir?

Yes, you can drink while you are taking Aciclovir. Alcohol won’t interfere with its antiviral properties. Since alcohol will reduce your ability to fight off infections, though, it’s best to keep your intake down. If you can avoid alcohol entirely until you’ve fully recovered, you should do so.

Abstaining from drinking while you’re taking Aciclovir will also reduce your risk of experiencing side effects. We’ll discuss this more in the next section.

Mixing Aciclovir and alcohol: safety concerns

It’s important to be aware of any possible interaction between any medication you take and alcohol, including Aciclovir tablets.

However, in the case of Aciclovir tablets and alcohol, there is no real risk of any danger and no need to be concerned about your safety.

Mixing Aciclovir and alcohol is considered safe and will not affect the way this popular herpes and viral infections medication works.

Mixing Aciclovir and alcohol: side effects

Like all medicines, Aciclovir can cause unwanted side effects as well as benefiting the user — although not everybody gets them.

To find out more about the possible side effects associated with Aciclovir, you can visit our Aciclovir side effects page. Side effects don’t affect the majority of Aciclovir users, but it’s always worth being aware of them just in case.

Combining alcohol and Aciclovir may mean that some of these side effects may be exacerbated, such as headaches, dizziness, nausea or drowsiness.

If you think you are experiencing any side effects due to mixing Aciclovir tablets and alcohol, then you should stop drinking alcohol. If they persist, you should seek advice from a doctor or pharmacist.

How to use Aciclovir tablets safely

It is very easy to use Aciclovir tablets safely. Simply follow the instructions you have been given by your doctor or pharmacist; the Aciclovir dosage and treatment plan will change according to your individual condition. Do not take this medicine in larger or smaller doses than your doctor or the directions on your prescription label suggest.

Aciclovir tablets can be taken with or without food. However, if you find you are suffering from side effects such as feeling or being sick (nausea), then it may help to take your medication after you have eaten.

You should swallow each tablet with water (or a non-alcoholic drink).

It is important to drink plenty of fluids whilst taking Aciclovir tablets to avoid dehydration and to keep your kidneys working well.

Drinking lots of water and reducing your alcohol intake while on Aciclovir will also help you to avoid side effects such as headaches too.
